A premarital fertility test for a man is mostly an examination, not a blood panel. Testicle size tells me more about sperm production than testosterone does, and one semen sample is never a diagnosis. Nine tests follow from that examination: total testosterone, FSH, LH, prolactin, HbA1c, TSH, free T3 and T4, the STD screen, and a semen analysis when indicated. Do it three to six months before the wedding.
Vanakkam, and welcome to my clinic.
Every wedding season I see the same piece of paper. A couple walks in holding a quotation from a diagnostic chain, 38 tests on it, sometimes 48, occasionally 88, and they want to know whether to pay for it. Nobody has explained a single line to them. That panel was built by a marketing team, not by a doctor.
What follows is premarital fertility testing in Chennai as I actually practise it: what I order before a marriage, what I don’t order, and why. Some of it will save you money. One part of it, whether you and your partner are related, decides the whole plan, and no package will ever think to ask you.
7 things couples get told wrong about premarital testing
Testosterone is the number men fixate on
It is the wrong one. 44% of men with completely normal sperm counts test ‘low’. FSH is the marker that tracks sperm production.
Penis size has nothing to do with fertility
Testicle size has everything to do with it. Men worry about the wrong measurement, and no laboratory package measures either one.
Gym testosterone is a contraceptive
Exogenous testosterone shuts down sperm production and is contraindicated when you are trying to conceive.
One semen sample is not a diagnosis
Only 64% of men have matching sperm concentration across two samples. A routine premarital semen test usually creates worry, not answers.
A blood count is not thalassaemia screening
Red-cell indices alone missed up to 37% of true carriers. The line on your quotation has to say HPLC.
Bigger packages are not better packages
38, 48 and 88-test bundles are priced on test count. The expensive, useful item is often the one left out.
Two weeks before the wedding is too late
Vaccines, repeat tests and a carrier result all need months. Three to six is the window.
🔎 What is a premarital screening test, and what is a pre marriage health checkup?
A premarital screening test looks for conditions that are silent in you but consequential for your partner or your children: carrier states like thalassaemia (spelled thalassemia on most Indian lab reports), transmissible infections, and blood group incompatibility. A pre marriage health checkup in Chennai is the packaged commercial version of that idea, usually 38 to 88 tests, of which about nine do the work. If you would rather see the whole male workup first, that is set out on my page for the infertility specialist in Chennai.
They aren’t the same thing, and the gap between them is where your money goes. People search for it as a pre wedding health checkup, a marriage medical test or simply a blood test before marriage; it is all the same request. A premarital screening test is a clinical decision. A pre marriage health checkup is a product.
Premarital fertility testing in a nutshell
Your examination matters more than your panel
Testicle size tells me more about sperm production than any blood test will. No laboratory package touches you, which is why they miss it.
Testosterone is the wrong number
44% of men with completely normal sperm counts still test ‘low’. FSH, not testosterone, is the blood marker that tracks sperm production.
Gym testosterone can make you sterile
Exogenous testosterone shuts down sperm production and is contraindicated when you are trying to conceive. Tell me before the wedding, not after.
One semen sample is not a diagnosis
Among men giving two samples, only 64% had matching sperm concentration. A routine premarital semen test usually creates worry, not answers.
Nine tests, and they follow the examination
Total testosterone, FSH, LH, prolactin, HbA1c, TSH, free T3 and T4, the STD screen, and a semen analysis only when indicated.
Three to six months before the date
Long enough to repeat anything abnormal, start folic acid, vaccinate, and act on a carrier result without panic.
I recorded two videos on this. The first one walks through the tests I order and why each one is on the list.
Video: premarital fertility testing, part 1 — which tests to do
The short version of that video: screen both partners, insist on HPLC rather than a plain blood count, get the four infection tests done without arguing about trust, and leave yourself enough runway before the wedding to act on anything abnormal. The evidence behind each of those is below.
🙋 The 3 things men actually ask me before marriage
Let me start where the consultation actually starts. In fifteen years I’ve had perhaps four men open with “I’d like carrier screening.” Almost every man who sits down in front of me before his wedding is worried about one of three things, and usually all three.
So we deal with these first, and the rest of the list follows from what we find.
1. “Is my size normal?” — testicle size, penis size and male fertility
This is the question underneath the appointment more often than any other, and men rarely ask it directly. They ask something else and wait to see whether I bring it up.
So let me separate two things that get tangled together, because one matters enormously for fertility and the other does not matter at all.
Testicle size matters. It is the single most useful thing my hands tell me. The testis is where sperm is made, and its volume is mostly seminiferous tubule, so a small or soft testis means reduced sperm production far more reliably than any blood test will tell you. I measure it, and when it’s borderline I confirm on ultrasound. In one series of young men with a varicocele, a total testicular volume under 30 cc and a size difference of more than 20% between the two sides both tracked with poorer sperm counts and motility (Raymo, 2025). This is why an examination is not optional and why a laboratory package that never touches you is missing the most informative part of the assessment.
Penis size does not affect fertility. Not length, not girth, not curvature within the normal range. Sperm is deposited at the cervix by an ejaculate that travels perfectly well regardless of dimensions. The only situations where anatomy genuinely interferes with conception are severe hypospadias, a significant curvature that prevents penetration, or an inability to have intercourse at all, and those are visible, uncommon, and treatable.
Men do not believe this, so here is the number. A meta-analysis pooling 34,060 men found a mean erect length of 12.42 cm, with a standard deviation of 1.63 cm (Wang, 2025). Most men who come to me convinced they are abnormal are sitting comfortably inside one standard deviation of that mean. If this is what’s actually worrying you, say so at the start of the consultation rather than at the end, and read small penis syndrome before you spend money on anything you saw advertised.
2. “Should I check my testosterone?” — usually not, and here is the evidence
Testosterone has become the number men fixate on before marriage, and it is the wrong number.
Here is the finding that should settle it. Among 1,164 men assessed for fertility, median morning testosterone was identical in men with normal and abnormal sperm concentration: 316 ng/dL in both groups. FSH, by contrast, was clearly higher in the men with a sperm concentration below 15 million/mL, 6.0 against 3.8 IU/mL. And among the men whose sperm concentration was entirely normal, 44.1% still had a testosterone below 300 ng/dL (Greenberg, 2023).
Read that last figure again. Nearly half of men with perfectly normal sperm production would be labelled “low testosterone” by a package report. That number would frighten a man three weeks before his wedding and change nothing about his fertility.
If I want to know about your sperm production from a blood test, I look at FSH, not testosterone. FSH is the pituitary’s report card on the testis: when the testis is failing, the pituitary shouts louder and FSH climbs.
When testosterone genuinely earns a test: low libido, poor morning erections, erectile difficulty, gynaecomastia, small or soft testes on examination, or a genuinely abnormal semen analysis. A symptom or a finding, not a wedding date.
Dr Shahs notes (from my clinical observation)
One warning I now give every young man, because I see it constantly and almost nobody arrives knowing it: if you are taking testosterone from a gym, you may be sterile right now.
Exogenous testosterone suppresses the pituitary, collapses the testosterone concentration inside the testis, and shuts down sperm production. It is explicitly contraindicated in men trying to conceive, and while sperm production usually resumes after stopping, the recovery time is highly variable and can complicate family planning considerably (Naelitz, 2025). Non-medical use among young men in recreational strength training is rising, and the reproductive suppression is well documented (Kowalik, 2026).
The injection your trainer recommends is a contraceptive with side effects. If you are on anything at all, tell me at the first visit and tell me honestly. It changes what I test, what I advise, and how long we need before the wedding.
3. “Is my sperm count okay?” — the test I am careful about, and why
This is my own field, so you might expect me to order a semen analysis for every man before his wedding. I don’t, and the reason is not cost.
A semen analysis is a much noisier measurement than patients realise, and the noise is in the man, not only in the laboratory. Among 1,075 men who each gave two samples, only 64% had concordant sperm concentration between the two, and only 52% concordant motility. The authors concluded plainly that one sample is insufficient to assess any abnormality (Punjani, 2021). Those were men already under fertility evaluation rather than healthy grooms, so the exact percentages won’t transfer, but the direction is the point: the same man’s numbers move. They also swing with abstinence period, a recent fever, illness and sleep.
So a single borderline report on a healthy 28-year-old with normal testes and no complaint tells you very little, and it tells it to him three weeks before his wedding. I’ve sat with too many grooms who spent their engagement convinced they were infertile and had a normal repeat analysis afterwards. The appetite for the test is real: 70% of 740 Jordanian adults surveyed supported it (Banihani, 2019). The appetite isn’t wrong. One unrepeated sample is just the wrong way to satisfy it.
When I do order it before marriage: an abnormal examination, small testes, a varicocele, a history of undescended testis, mumps orchitis after puberty, testicular surgery, chemotherapy or radiation, any anabolic steroid use, or a man anxious enough that he won’t settle without knowing. Then I use a laboratory in an external quality-control programme that follows the current WHO method, and I book the follow-up to explain the result. That is a question you are entitled to ask any lab, and no package brochure answers it.
What the numbers mean, and why one report is never a diagnosis, is set out in full on my page about the semen analysis test in Chennai.
Those three questions, plus an examination, decide almost everything about what I order next. The list below is what remains.
👨 Premarital testing for men: the 9 tests I order
This is my panel for a male fertility test in Chennai. Not a package, not thirty-eight tests, and not the same list for every man who walks in. It follows the examination, and the examination decides how much of it I actually order.
- Total testosterone. The baseline. Drawn in the morning, because it falls through the day. Read it alongside the examination, never on its own.
- FSH. The one that actually tracks sperm production. When the testis is failing, the pituitary shouts louder and FSH climbs. A raised FSH with small testes tells me more than any other pair of findings on this list, and it is the usual starting point when a report comes back showing a low sperm count or no sperm at all.
- LH. Read with testosterone. High LH with low testosterone points to the testis; low LH with low testosterone points above it, to the pituitary. That distinction changes the treatment completely.
- Prolactin. Cheap, and it catches the occasional pituitary problem that presents as low libido or poor erections. A high prolactin needs explaining, not ignoring.
- HbA1c. Three months of sugar control in one number. Diabetes affects sperm, erections and pregnancy outcomes, and India’s numbers make this permanent on my list.
- TSH. The thyroid screen.
- Free T3 and free T4. Thyroid function proper. Both over- and under-active thyroid disturb libido, erections and semen parameters, and TSH alone occasionally misses it.
- The STD screen. HIV, hepatitis B, hepatitis C and syphilis. Enough of a subject that it has its own section below.
- Semen analysis, in indicated patients. Not routine. Ordered when the examination is abnormal, when the hormones are abnormal, after undescended testis, mumps orchitis, testicular surgery or chemotherapy, with any anabolic steroid use, or when a man is anxious enough that he needs to know.
Those are the medical tests before marriage that actually change a decision. Notice what is not on that list: no vitamin panel, no wide lipid profile, no liver and kidney screen, no ESR, no urine routine. Those are what the 38-test bundle adds to look generous.
👩 Premarital testing for women: what she actually needs
A female premarital checkup is shorter than most packages suggest, and the most valuable part costs nothing.
- A menstrual history. Regular, predictable cycles tell me more about her ovulation than any hormone panel I could order. This is a conversation, not a test.
- TSH, and free T3 and T4 if indicated. Undiagnosed hypothyroidism disturbs ovulation and raises early-pregnancy risk. It is common in Indian women and treated with one tablet a day.
- Fasting blood sugar, and HbA1c where there is reason. Family history, a high BMI, or irregular cycles with possible PCOS.
- Rubella IgG. If she is not immune she can be vaccinated now, but MMR is a live vaccine, so she must avoid conceiving for a month afterwards and it is not given in pregnancy. Easy in month five. Impossible in week two.
- An examination. Not just an interview. Vaginismus and other causes of an unconsummated marriage are common, entirely treatable, and far easier to raise before the wedding than three months after it.
- A day-2 pelvic ultrasound, only if the history raises something. Irregular cycles, heavy bleeding, or significant period pain. History first, scan second, never the other way round.
What is deliberately absent: a routine AMH, and a full FSH, LH, prolactin and oestradiol panel in a woman whose periods arrive predictably. Both are covered further down, in the section on tests you will be sold and do not need.
🦠 STD test before marriage: HIV, hepatitis B, hepatitis C and syphilis
This is the section couples most want to skip and least should. It applies to both of you, and it is four tests, not a negotiation.
HIV, hepatitis B, hepatitis C and syphilis — the sexually transmitted infection screen, for both of you
This is the uncomfortable one. Couples ask me whether they can skip it because they trust each other. Trust isn’t the point. These infections can sit silently for years and predate either of you.
One thing nobody explains: a negative result only covers exposures up to that test’s window period. A test done five months before the wedding says nothing about the five months after it. If there’s been an exposure since, the test needs repeating, and that is not an accusation, it’s just how the assays work.
All four are worth knowing because all four change something you’d do:
- Hepatitis B. If one of you is positive, the other is checked for existing immunity first, then vaccinated on a three-dose schedule over six months. For the sexual partner of someone who is HBsAg-positive, immunity should be confirmed by a blood test one to two months after the last dose rather than assumed. Use protection until it’s confirmed. The positive partner needs their own workup, because some people need antiviral treatment and some don’t, and a baby born to a positive mother needs vaccine and immunoglobulin at birth.
- Hepatitis C is now curable in most people with eight to twelve weeks of tablets. It’s the test people dread most and the diagnosis that has changed most in the last decade.
- Syphilis is curable with penicillin.
- HIV, treated early, is a chronic condition with a normal life expectancy. Two facts matter enormously here and rarely get said in Chennai: a person on treatment with a sustained undetectable viral load, confirmed on monitoring rather than assumed, does not transmit HIV sexually, and the negative partner can take PrEP. Transmission to a baby is preventable. A positive result is not the end of a marriage or of having children.
What about chlamydia? I don’t put it on the routine list, but I do test when there’s a reason, and you should know why it matters. Chlamydia is silent in most women, and it’s a leading infectious cause of blocked tubes. If either of you has had a previous partner with an infection, unexplained pelvic pain, or a past pelvic infection, ask for it specifically. That history also changes my answer about tubal testing further down this page.
If any result does come back positive, talk to me before you talk to anyone else. That conversation is what my STD clinic in Chennai is for. What you tell me is not shared with your family or anyone else’s. I should be straight about one limit, though: where a result affects the health of the person being screened alongside you, I will work with you on how and when they are told. I won’t hide a transmissible infection from someone I am also treating. In practice this is almost always a conversation we have together in the room, and it goes far better than people fear.
🧬 Thalassaemia and carrier screening: what your children inherit
Once the infections are settled, this is the part that decides something about your children rather than about the two of you. It is also the line most often missing from a Chennai package.
Haemoglobin with HPLC — thalassaemia carrier screening, for both of you
This is the most valuable test on the list and the one most commonly done badly.
Beta-thalassaemia carriers aren’t rare in India. A meta-analysis pooling 69 published studies put the carrier rate in the general population at 3.74% (95% CI 2.52–4.97) (Sumedha, 2023), and a targeted antenatal screening programme across 36 districts found 6.8% of women carried a haemoglobinopathy of some kind, of which more than half were sickle cell rather than beta-thalassaemia (Agarwal, 2025). Being a carrier is what your report may call thalassaemia minor or thalassaemia trait. You’re healthy. You carry one copy.
Here’s what the packages get wrong. Most bundles screen with a complete blood count and read MCV and MCH. That isn’t good enough. When 2,220 healthy young adults were screened by both methods, red-cell indices alone had low positive predictive value and missed up to 37% of true carriers confirmed on HPLC (Bharti, 2020). That study was in Himachal Pradesh and the exact figure won’t transfer unchanged to Tamil Nadu, but the direction isn’t controversial: a blood count is not a carrier test.
So look at your quotation and find the line that says HPLC or haemoglobin electrophoresis. If it only says CBC or haemogram, you’re not being screened for thalassaemia. You’re being screened for anaemia, which is a different question. If you can’t tell which it is, send me a photograph of the quotation on WhatsApp and I’ll mark it up for you.
Two caveats no package will tell you. First, HPLC is read alongside the blood count and iron studies, because iron deficiency lowers HbA2, the marker HPLC reads, and can mask a carrier; nearly a quarter of confirmed carriers in one Indian series also had iron deficiency anaemia (Singh, 2025). Second, HPLC does not reliably detect alpha-thalassaemia – there the flag is a small red cell with a normal HbA2, and the answer is alpha-globin gene testing. It does pick up sickle cell and HbE carriers, and those paired with a beta-thalassaemia carrier carry the same one-in-four risk, though severity varies from moderate anaemia to transfusion dependence.
If both of you are carriers, what happens next
You are entitled to know this before the wedding rather than at twenty weeks of pregnancy. The exact mutation is confirmed in both of you, you see a genetic counsellor before conceiving, and in a pregnancy the fetus can be tested by chorionic villus sampling at 11 to 13 weeks or amniocentesis from about 15 weeks. Couples who would rather not face that decision inside a pregnancy can consider IVF with pre-implantation testing. The arithmetic per pregnancy is one child in four unaffected, two healthy carriers, one with thalassaemia major. If a test comes back affected, the choice is to continue with a transfusion and transplant plan prepared in advance, or to end the pregnancy. All of it is easier six months before a wedding than five months into one.
Blood group and Rh typing before marriage — both of you
Cheap, quick, and it matters later rather than now. If she’s Rh-negative and he’s Rh-positive, that isn’t a problem for the marriage. It’s a flag for her first pregnancy, when anti-D prophylaxis becomes important. Knowing it now means her obstetrician isn’t finding out at 28 weeks.
💑 Marrying a relative: consanguinity and premarital genetic screening in Tamil Nadu
No premarital package in this city asks about this.
In Tamil Nadu and across south India, marrying within the family is normal, expected and often actively arranged. That’s culture, it isn’t a mistake, and I’m not here to tell anybody who to marry. But relative marriage is medically relevant, and pretending otherwise helps nobody.
The numbers aren’t small. A nationally representative survey of older Indian adults found consanguinity across south Indian states ranging from 5% in Kerala to 28% in Andhra Pradesh (Kundu, 2024). Those are neighbouring states rather than Tamil Nadu, and the cohort was aged 45 and above, so today’s rates are lower. Pooling India’s two most recent National Family Health Surveys, both close and distant consanguinity carried a significantly higher risk of spontaneous abortion (Kalam, 2024), and in a survey of 8,553 children in Karnataka, consanguineous parents had roughly two and a half times the odds of a child with an eye disease of likely genetic origin (Kemmanu, 2019).
Degrees of consanguinity in marriage: uncle–niece, cross-cousins, and why they aren’t the same
This distinction gets flattened everywhere and it matters here more than almost anywhere else in India.
Let me use the clinical terms first, because the everyday ones are ambiguous. A maternal uncle and niece share about one quarter of their genes: that’s a second-degree relationship. Cross-cousins, the children of a brother and a sister, share about one eighth: a third-degree relationship. The uncle–niece match therefore carries roughly double the excess risk of a cousin match.
Here’s why I’m being pedantic. In Tamil, murai maaman gets used for both, sometimes for the mother’s brother and sometimes for his son. If you tell me “murai maaman marriage” I still don’t know which of the two you mean, and the difference is a factor of two. So tell me the actual relationship: is he your mother’s brother, or your mother’s brother’s son?
To put the numbers in proportion, because “double” frightens people badly: roughly two to three in every hundred babies are born with a significant congenital condition, in any couple anywhere. For a cousin marriage that figure roughly doubles, and for an uncle–niece marriage roughly doubles again. Those are the standard figures used in genetic counselling rather than a finding from any single paper. Read them the right way round: the great majority of children born to related couples are entirely healthy, and most of the risk any couple carries is the same risk every couple carries. What shifts is the chance you both carry the same rare recessive variant, which is exactly what carrier screening is built to find.
Carrier screening for couples in Chennai: when it’s worth the money
This is the one place I reverse the argument I made above about expanded panels. For an unrelated couple with no family history, HPLC plus a good family history is usually enough. For a related couple, an expanded panel moves from optional to sensible, because shared ancestry is exactly what those panels were designed for. The condition stays the one I set earlier: order it with a counselling plan already in place.
Reading the consanguinity evidence honestly
Your marriage is not unsafe
The great majority of children born to related couples are entirely healthy. This is a shift in risk, not a verdict.
Nobody should call off a wedding over this
Mandatory premarital screening across the Middle East did not stop most at-risk couples from marrying. What it did reduce was affected births, and only in countries that also provided prenatal diagnosis and access to termination (Saffi, 2015).
Recessive conditions matter more here
Shared ancestry raises the chance you both carry the same rare variant, which is exactly what carrier screening is built to find.
The expanded panel earns its place
The test I argued against as a default is the test I’d order for you, provided somebody is lined up to explain the result.
Give me an hour for the family history
Infant deaths, disability, transfusion-dependent relatives, early menopause. These tell me what to look for.
Say it before I have to ask
Nobody can act on a fact they were never given, and this one almost never gets volunteered.
So when you sit down in front of me, say it plainly: we’re related, and this is how. I won’t react, because I hear it several times a week in this clinic. It simply moves the plan, from a standard panel to a targeted one, and from a form to a proper genetic history.
Private 1-on-1 consultation
Getting married in the next six months? Let’s do this properly, once.
One consultation, both partners, a real history and only the tests you need. We talk for a good while, I examine you, then I write a short list you can take to any lab in Chennai. Nothing from it goes to your family or your partner’s family. If you’re related to your partner, or there’s thalassaemia anywhere in either family, say so when you call and I’ll keep a longer slot.
🩺 The two things no premarital test package can do
These are the two items that decide my test list more often than any result does, and they are exactly what a package cannot sell you.
A physical examination before marriage — both of you
For him: the genital examination, with testicular volume
This costs nothing and gets skipped by every diagnostic package in Chennai, because a laboratory can’t bill for it.
I examine every man properly. Testicular volume tells me about sperm production directly, and small, soft testes point to a problem long before a blood test does. I’m also feeling for a varicocele, checking both vasa deferentia are present, and looking for undescended testis or a hernia repair scar. A man who had surgery for an undescended testis at four years old is carrying information about his fertility that no 88-test panel will ever find.
A scrotal ultrasound isn’t a routine premarital test. I order it only when the examination finds a varicocele, an asymmetry in testicular volume, or a lump. If something does turn up, what happens next is set out on my page about male infertility assessment.
For her: menstrual history, an examination, and a day-2 pelvic ultrasound if indicated
Regular, predictable cycles tell me more about her ovulation than any hormone panel I could order. Irregular cycles, very heavy bleeding, or significant period pain are worth investigating, and that’s when a day-2 ultrasound of the ovaries and uterus earns its place.
She should be examined too, not just interviewed. Vaginismus and other causes of an unconsummated marriage are common, entirely treatable, and far easier to raise before the wedding than three months after it. The order matters: history first, examination, then a scan only if something has been raised.
A family history: the cheapest premarital screening there is
Not a form. A conversation.
I want to know about infant deaths in the extended family, children with disability, repeated miscarriages in sisters and aunts, anyone on regular blood transfusions, early menopause in her mother or sisters, and whether the two of you are related. It’s the cheapest part of the consultation and it changes my test list more often than anything else on it. A diagnostic chain will never do this, because you can’t put it on a price list.
💊 Three things that aren’t tests and matter more than most of them
These get left off every package in Chennai because there’s nothing to bill.
Folic acid before marriage, started before you conceive rather than after
Nothing else here has evidence this strong behind it. A synthesis of 17 guidelines and consensus documents recommends starting folic acid at least three months before conception and continuing through the first trimester, at 0.4 mg daily for low-risk women, 1.0 mg for moderate risk, and 4.0 to 5.0 mg for high-risk women, a group that includes a previous affected pregnancy, diabetes, or anticonvulsant treatment. Diet alone isn’t sufficient, and routine folate blood testing isn’t recommended (Li, 2026).
One caution that matters particularly in Chennai: high-dose folic acid can mask a vitamin B12 deficiency, and B12 deficiency is common in long-term vegetarians. If she is going on 4 or 5 mg, her B12 should be checked first.
That is the same window I keep asking couples for. The neural tube closes before most women know they’re pregnant, so starting after a positive test is starting late.
A medication review before pregnancy
Isotretinoin for acne is the classic premarital catch in this city, and it needs stopping a month before conception. Sodium valproate, methotrexate, warfarin and ACE inhibitors all need a conversation and often a switch. Bring your tablets, or a photo of the strips, to the consultation. This takes two minutes and it’s one of the few genuinely preventable disasters in reproductive medicine.
Contraception and HPV vaccination before the wedding
Plenty of couples don’t want a pregnancy in the first year, and nobody in a premarital package ever asks. If that’s you, decide on contraception before the wedding rather than in the second week. It’s also the right moment to discuss HPV vaccination, which is worth considering into the twenties and is one of the more valuable preventive things available to a couple at this stage.
🚫 The 4 premarital tests you’ll be sold and probably don’t need
Each of these is a real test with a real use. My argument is narrower: run routinely, on a healthy couple, before a marriage, they answer a question nobody asked and frequently create a problem that didn’t exist.
1. AMH, sold as a “fertility score” for her
AMH has become the headline act of premarital packages aimed at women, and it’s the one I argue about most.
The evidence is genuinely mixed, and I’ll give you both sides rather than the half that suits me. A prospective cohort of 102 healthy pregnancy planners found no predictive effect of AMH on time to pregnancy once female age was accounted for (Depmann, 2017), and a larger preconception cohort of 993 couples found AMH wasn’t significantly associated with fecundability (Qiu, 2022). Against that, a cohort of 260 women did find pregnancy rates rising with AMH, 60.1% in the low group against 78.3% in the high group, with a shorter time to pregnancy at high AMH (Korsholm, 2018). But that same study found wide variation in fertility among women with near-identical AMH, and natural conceptions right down to an AMH of 1.2 pmol/l.
So there is a real association at population level, but nobody has shown that an AMH number changes what a healthy 26-year-old should do. Age is the variable that matters, and she already knows it.
What AMH reliably produces in a 26-year-old who isn’t trying to conceive yet is fear. A number in the lower half of the range gets read as running out of time, and I’ve watched that distort wedding plans and career decisions.
There is a woman for whom I do want this number. She’s in her late thirties. Or her mother or sister reached menopause early, which is a real and often-missed indication. Or she’s had ovarian surgery or chemotherapy. Or her cycles are irregular, where AMH has a genuine role in assessing PCOS. (One cohort saw a signal towards lower fecundability with low AMH in women with irregular cycles, but it did not reach statistical significance and is not on its own a reason to test.) Or the couple is actively planning fertility treatment and the result will change the plan. In those women it’s the right test. As a routine premarital screen on a woman in her twenties with regular cycles, it isn’t.
2. A full female hormone panel when her cycles are regular
FSH, LH, prolactin and oestradiol, run on a woman whose periods arrive predictably every month. Regular cycles have already answered the question those tests were going to ask, and the panel mostly returns borderline values that need repeating. I order them when cycles are irregular, absent, or when there is galactorrhoea or suspected PCOS.
3. HSG or any tubal patency testing
An HSG is invasive, uncomfortable, carries a small infection risk, and exists to answer a question that only arises after a couple has been trying for a year without success. I don’t think it belongs on a premarital quotation, and if it’s on yours, that tells you something about who designed the package.
The exception is real, though, so don’t take this as an absolute. A woman with a history of pelvic inflammatory disease, a past chlamydia infection, an ectopic pregnancy or previous pelvic surgery has an actual reason to have her tubes assessed, and for her the conversation starts earlier than a year.
4. Expanded genetic carrier screening panels — 88 or 420 genes — as a default
This one needs care, because for the right couple I’d order it without hesitating.
Large sequencing panels are a genuine advance. The difficulty with running one by default is that a broad panel on an unselected couple returns variants of uncertain significance, findings nobody can interpret with confidence, and an ambiguous result is heavy to carry. In practice, access to a trained genetic counsellor in Chennai is limited, so those results often land with a couple who have nobody to explain them. That’s my clinical observation, not a statistic.
Which is exactly why, when I do order a panel, I order it as part of a plan that already includes who will explain the result. A panel without that is worse than no panel.
When I recommend one: when there’s consanguinity, when there’s a family history of a genetic condition, when a previous child or a relative’s child has been affected, or when both partners come from a community with a known founder mutation. That’s a targeted decision made after a history, not a line item you tick because it was in the platinum package.
📦 The 38-test premarital package itself
Back to that piece of paper.
The test count is the product. A package priced against a competitor has to look bigger, so it grows by adding cheap assays: vitamin levels, lipid profiles, liver and kidney panels, urine routine, ESR. They run off the same two tubes of blood, they inflate the banner number, and they answer nothing you asked. Meanwhile HPLC, the expensive and genuinely useful item, is sometimes not in there at all.
You aren’t buying nine good tests plus twenty-nine harmless ones. You’re buying twenty-nine chances at an incidental abnormal value that’ll need a repeat, a specialist opinion, and six weeks of worry before your wedding.
Part two of my video makes this argument directly, including the tests I actively tell people not to do.

🧪 Fertility test before marriage: what a couple fertility test can and can’t tell you
A fertility test before marriage is the phrase most people search for, and it promises more than any test can deliver.
A pre marriage fertility test can tell you whether either of you carries something worth knowing about, whether there is an infection needing treatment, whether her thyroid and sugars are in order, and whether his examination is normal. That is most of the value on offer.
What no couple fertility test can tell you is whether you will conceive easily. No test predicts that, and anyone selling you one is selling reassurance rather than information. Most couples conceive within a year of trying, and that year is the only real test there is. It is also why I do not investigate tubes or run full hormone panels before a wedding: there is no question yet for them to answer.
If a year of trying passes without a pregnancy, that is when a full workup belongs, and what it involves is on my pages about male infertility causes and female infertility.
⏱️ When to do a pre marriage health checkup in Chennai: the three-to-six-month window
Three to six months before the wedding date. I’ve given that answer for years, and the reason is arithmetic rather than superstition: every useful thing you might have to do afterwards takes weeks.
- An abnormal result needs repeating. Almost nothing should be acted on from a single value, and a repeat plus a review is a month.
- Folic acid should start three months before conception (Li, 2026).
- Rubella vaccination needs a month of avoiding conception afterwards. Trivial in month five, impossible in week two.
- Hepatitis B vaccination is three doses over six months for the non-immune partner, plus a confirmatory antibody test afterwards.
- If both of you are carriers, you need an unhurried conversation about molecular confirmation and what your options are in a pregnancy. This one can’t be rushed and shouldn’t be.
- Medication changes need a washout. Isotretinoin needs a month clear of conception.
Two weeks before the muhurtham, you get a folder of numbers and no time to act on them.
So if your date is already close, call today rather than next week. We can still get the HPLC and the infection screens done and act on the results, and the sooner you call, the more of that list stays open to you.
💰 What a premarital health checkup costs in Chennai
I won’t quote you a figure for someone else’s package, because the price depends on which of the nine tests you actually need and where you have them done. What I can do is show you how these quotations get built, so you can read your own.
Packages are priced on test count, not on value. The headline number, 38 tests or 48 tests, is the marketing. The real cost to the lab sits in a handful of items; most of the rest are cheap automated assays running off the same two tubes of blood, which is exactly why adding them is such an easy way to make a package look generous.
The genuinely useful items are the ones most often missing. HPLC costs more than a CBC, so a package competing on price has every incentive to leave it out, and a clinical examination can’t be billed by a laboratory at all.
Worth paying for: a consultation where somebody takes a history and examines you, the HPLC, the four infection screens, and the basic sugar and thyroid tests.
What isn’t: tests nobody can give you an indication for. One question settles it, and you’re entitled to ask it of any lab or any doctor, including me: what will you do differently depending on this result? If there’s no answer, don’t buy the test. And if the lab won’t answer, read the list to me instead, on +91 97907 83856.
📍 Where to get a premarital health checkup in Chennai
You have three realistic routes, and they aren’t equivalent.
- A diagnostic chain package. Convenient, priced attractively, available near you, and chosen by a marketing team. Nobody examines you and nobody takes a family history. If you go this way, check the package says HPLC and includes all four infection screens, and be ready to ignore the extras. If you can’t tell which line is which, read the quotation out to me on +91 97907 83856. It takes five minutes.
- A hospital premarital package. Usually broader and more expensive, often with a consultation attached. Better, but still built as a product first.
- A clinician who writes you a list. You get examined, your history taken, and the list is yours rather than a package. That’s how I work.
My clinic is at No 21, Sree Kalki Apartments, Ground Floor, Bazullah Road, T-Nagar, Chennai 600017, and you can find it on Google Maps. Couples travel in from Adyar, Velachery, Anna Nagar, Porur, Mylapore, Kodambakkam, Tambaram and along OMR, and the same clinic runs my general sexologist practice in Chennai. The consultation happens in T. Nagar; the tests themselves you can have done wherever is convenient for you. Call +91 97907 83856 and I’ll write you the list.
📞 What happens at a premarital consultation in Chennai
People hesitate because they don’t know what they’re walking into, so let me remove that.
- You call and we fix a time. You don’t have to explain anything to whoever picks up. Say “premarital consultation” and that’s enough.
- Come as a couple if you can. If your partner can’t, come alone; half an assessment done well beats none.
- We talk first, for a good while. Cycles, illnesses, surgeries, medications, family history, whether you’re related, and whatever’s actually worrying you. Most of the value is here.
- I examine you, then write the test list. Usually short, and it’s yours: take it to any lab you like.
- We sit down again with the reports and go through every number in plain language, planning anything that needs action against your wedding date.
Nothing goes to your family, your partner’s family, or anybody else. Not the appointment, not the reports.
And if what’s actually worrying you isn’t fertility at all, if it’s performance, or pain, or the fact that you’ve never discussed sex with your partner and the wedding is in eleven weeks, say that instead. It’s a very common reason to book a premarital check, it’s treatable, and you can read about unconsummated marriage or psychosexual counselling first if you’d rather read than call.
Call today rather than next week
The sooner you call, the more of the list stays open to you. Tell me your wedding date and whether you’re related to your partner, and I’ll tell you what still fits in the time you have.
❓ Premarital fertility testing in Chennai: your questions answered
What is a pre-marital screening test?
A set of tests done before marriage to find conditions that are silent in you but consequential for your partner or your children: carrier states like thalassaemia and sickle cell, transmissible infections, and blood group incompatibility. It is a clinical decision about which tests you need, not a fixed package.
Where can I get a premarital health checkup in Chennai?
Either from a diagnostic chain, which sells a fixed package chosen by a marketing team, or from a clinician who examines you and writes a list that fits you. If you use a package, check it says HPLC and not just CBC. That one line is the difference between real thalassaemia screening and none. Call +91 97907 83856 and I’ll write you the list.
Which medical tests should be done before marriage?
For the man, nine: total testosterone, FSH, LH, prolactin, HbA1c, TSH, free T3 and T4, the STD screen (HIV, hepatitis B, hepatitis C, syphilis), and a semen analysis when indicated. For the woman: a menstrual history, thyroid, blood sugar, rubella IgG, an examination, and a day-2 scan only if the history raises something. Both of you also need HPLC for thalassaemia carrier status and blood group with Rh.
How much does a pre-marital medical test cost in India?
It varies widely, and the price tracks the number of tests rather than their usefulness. Check the package contains HPLC and the four infection screens, then ask what will be done differently based on each remaining test. A shorter, correctly chosen list often costs less and tells you more.
How much does a premarital health checkup cost in Chennai?
Chennai packages are priced on test count, so a bigger bundle can cost less than the nine tests that matter while omitting the most important one. The cost that actually varies is HPLC. Read your quotation to me on +91 97907 83856 and I’ll tell you what to keep.
Why is a thalassemia test needed before marriage?
Because thalassaemia is recessive and carriers are healthy, so you cannot tell you are one. Around 3.74% of Indians carry beta-thalassaemia (Sumedha, 2023). If both partners are carriers, each pregnancy carries a one-in-four risk of thalassaemia major. Insist on HPLC: red-cell indices alone missed up to 37% of carriers (Bharti, 2020).
Can two thalassemia minor carriers marry?
Yes. Carriers are healthy and it is no barrier to marriage. What changes is the pregnancy plan: the mutation is confirmed in both partners, you see a genetic counsellor before conceiving, and the fetus can be tested by chorionic villus sampling at 11 to 13 weeks. In each pregnancy, three in four children are healthy.
We are cousins. Do we need extra tests?
Yes, and the degree matters. Cross-cousins share about an eighth of their genes; a maternal uncle and niece share about a quarter, roughly double the excess risk. Shared ancestry raises the chance you both carry the same recessive variant, so an expanded carrier panel becomes worth doing. Tell your doctor which relationship it is.
Should a man do a semen analysis before marriage?
Not routinely. Among 1,075 men giving two samples, only 64% had concordant concentration and 52% concordant motility, so one sample is insufficient to assess any abnormality (Punjani, 2021). I order it when the examination is abnormal, after undescended testis, mumps orchitis, testicular surgery or chemotherapy, or when a man needs the answer to settle.
Is an AMH test worth doing before marriage?
Usually not. The evidence is mixed: AMH did not predict time to pregnancy once age was accounted for (Depmann, 2017), while another cohort found higher pregnancy rates at higher AMH (Korsholm, 2018). Nobody has shown it changes what a healthy woman in her twenties should do. It earns its place in her late thirties, with irregular cycles, or after ovarian surgery.
When should we do the check-up?
Three to six months before the wedding. That leaves time to repeat an abnormal result, start folic acid three months before conception, complete a hepatitis B course, take rubella vaccination and still avoid conceiving for the required month. If your date is close, call anyway on +91 97907 83856.
Do both partners need to be tested, or only the man?
Both. Carrier screening only means anything as a pair: one carrier isn’t a problem for this pregnancy, two carriers of the same condition is the finding that matters. Blood group and infection screening are similarly paired. A premarital assessment done on one person is half an assessment.
Is there a premarital test near me in Chennai?
The tests themselves can be done at any accredited laboratory near you. What should not be outsourced is deciding which tests you need. Couples come to the T. Nagar clinic from across the city, get the list written, then have the bloods drawn close to home. Call +91 97907 83856.
Which doctor should you see for a premarital check in Chennai?
For the man, an andrologist, because the testicular examination is the part packages skip. For the woman, a gynaecologist for the pelvic side. What matters more is that somebody examines you both and takes a family history. That is how I work, in T. Nagar. Call +91 97907 83856.
Are premarital fertility tests accurate?
It depends on the test. HPLC for carrier status, blood grouping and the infection screens are reliable. Semen analysis is far less reproducible than patients assume, which is why one sample is never a diagnosis. AMH measures ovarian reserve accurately while predicting natural conception poorly.
Two patterns account for most of the harm I see from premarital testing. The first is damage from a number without a conversation: a young man arrives having read a word he didn’t understand on a package report handed to him with no explanation, convinced for a fortnight that he can’t have children. His examination is normal, his repeat analysis is normal, and none of it needed to happen.
The second costs more. A couple comes to me after their first pregnancy is found to carry thalassaemia major, and the premarital package they paid for has 38 tests on it and no HPLC. They did everything they were asked to do. They were sold the wrong list.
That’s why I’d rather you arrived with a wedding date and a family history than with a folder of results.
