Most people think of tuberculosis as a lung disease with a cough. But Mycobacterium tuberculosis travels through the bloodstream, and when it settles in the reproductive organs it causes genital tuberculosis — a quiet, slow, scarring infection that often produces no symptoms at all until a couple cannot conceive.
It is one of the most important causes of infertility in India, and one of the least discussed. Women arrive at our clinic in Patna having been investigated for a year, with no explanation, and no one has looked for it. Others arrive having been put on nine months of anti-TB treatment on the strength of a single test that should never have been used alone. Both situations are avoidable, and this article is about how.
Can TB Cause Infertility? The Short Answer
Yes. Tuberculosis affecting the reproductive organs — genital tuberculosis — is a well-recognised cause of infertility in both women and men. In women it scars and blocks the fallopian tubes, damages the uterine lining and creates pelvic adhesions. In men it can obstruct the epididymis and cause azoospermia. Most people who develop it never had obvious lung tuberculosis and often have no symptoms beyond difficulty conceiving. The infection itself is curable with anti-tubercular treatment, but the scarring it leaves behind frequently is not — which is why IVF plays a central role, and why early diagnosis matters more here than in almost any other cause of infertility.
What Is Genital Tuberculosis?
Genital tuberculosis is tuberculous infection of the reproductive tract. It is almost always secondary: the bacteria enter through the lungs first, then spread through the bloodstream or lymphatic system to the genital organs, where they can lie quietly for years before causing recognisable problems.
Two features make it unusually difficult to catch. First, it is paucibacillary — very few organisms are present in the tissue, which is why standard tests so often come back negative even when disease is present. Second, it is frequently silent. Many women have no pain, no fever, no weight loss and no cough. The first sign is that a pregnancy does not happen.
It falls under extrapulmonary tuberculosis, and genital involvement accounts for a meaningful share of all extrapulmonary cases — commonly cited at around 9%.
How Common Is Genital TB in India?
India carries the largest tuberculosis burden in the world, and that changes what a fertility specialist here has to consider compared with one in Europe or North America.
Among infertile women, reported prevalence of genital TB globally sits at roughly 5–10%. In developed countries the figure falls below one per cent. In Indian series it has been reported as high as around 19%, and one recent Indian review estimates genital TB contributes to a substantial share of infertility cases nationally, concentrated in women aged 20 to 40.
Those ranges are wide because diagnosis is genuinely difficult and different studies use different criteria — which is a point worth holding on to, because it becomes important later in this article. But the direction is not in doubt: in Bihar and across north India, genital TB belongs on the list of things to actively exclude in unexplained infertility, not on the list of rare curiosities.
How Genital TB Affects Female Fertility
Once established, the infection causes chronic inflammation, fibrosis and scarring. Where that scarring happens determines what it does to fertility.
Tubal Damage — the Most Common Mechanism
The fallopian tubes are involved in the overwhelming majority of cases. TB inflames the delicate lining, destroys the cilia that move the egg, and scars the tube shut. Sometimes the tube fills with fluid, forming a hydrosalpinx. Once a tube is blocked, natural conception through that side is not possible, and a hydrosalpinx also reduces the success of IVF unless it is dealt with first. This is usually the point at which genital TB is first suspected — on an HSG test and what the report means.
Endometrial Damage — the Harder Problem
Where TB infects the uterine lining, the consequences are different and more difficult. The endometrium becomes thin and unresponsive, and adhesions can form inside the uterine cavity. A thin endometrium is one of the most stubborn problems in reproductive medicine, and it is the reason some women with treated genital TB still struggle after IVF: the embryos are fine, but the lining will not support implantation. If you have had repeated implantation failure and recurrent loss with no explanation, this is one of the causes worth actively excluding.
Ovarian and Pelvic Involvement
Prolonged inflammation can affect the ovaries themselves, and Indian data on women with latent genital TB has found lower anti-Müllerian hormone levels and lower antral follicle counts than in comparable infertile women without it. If you are trying to make sense of your own reserve numbers, our explainer on what a good AMH level actually means covers the interpretation. Dense pelvic adhesions can also distort the anatomy so that even structurally open tubes cannot function normally.
Genital TB Symptoms in Women
The single most important thing to understand is that there may be no symptoms at all. Infertility is frequently the only presenting feature. Where symptoms do occur, they are easy to attribute to something else:
- Menstrual changes — scanty periods, irregular cycles, or periods stopping altogether. A previously normal period becoming very light is a classic and frequently ignored sign; our guide on what counts as a normal period sets out what should prompt a review.
- Chronic pelvic pain — often low-grade and long-standing rather than acute.
- Abnormal vaginal discharge.
- Pain during intercourse.
- Recurrent miscarriage or repeated failed IVF cycles where no other cause is found.
- Constitutional symptoms — low-grade evening fever, unexplained weight loss, tiredness, night sweats. These are the classic TB symptoms, and in genital TB they are frequently absent.
These overlap heavily with other conditions — endometriosis, pelvic inflammatory disease and PCOS, which does not close the door on motherhood — which is a large part of why the diagnosis is delayed.
Can TB Cause Infertility in Men?
Yes, and this is one of the least-discussed areas of male infertility in India. Male genital TB usually affects the epididymis first, and often presents as a painless scrotal swelling that is mistaken for something else.
Epididymal involvement and obstruction. The epididymis is the coiled tube where sperm mature and through which they travel. TB scarring here blocks that passage. Sperm continue to be produced normally in the testis but cannot get out — obstructive azoospermia, where a semen analysis shows no sperm at all despite normal production. Our page on what a zero sperm count actually means explains why this particular form is one of the more hopeful ones.
Prostate and seminal vesicles. Involvement here affects semen volume and the transport of sperm, and may show up as an abnormal semen report without an obvious cause — see what abnormal sperm results actually mean.
Testicular involvement. Less common, but where the testis itself is affected, sperm production can be directly impaired.
Symptoms to take seriously: a painless or mildly painful scrotal lump or swelling, a thickened or beaded epididymis, a discharging scrotal sinus, burning on urination, or blood in the semen. A man with unexplained azoospermia and any past TB exposure deserves a proper evaluation for this — the wider picture is in our guide to what causes male infertility and how it is treated, and because several causes often coexist, it is worth also reviewing how chronic stress affects sperm count and motility.
The encouraging part: obstructive azoospermia caused by TB is one of the more retrievable situations in male infertility. Sperm are usually still being made, and surgical sperm retrieval combined with ICSI can achieve pregnancy even when the passage cannot be reopened.
How Genital TB Is Diagnosed
This is where the topic becomes genuinely complicated, and where patients most need to understand what is happening. Because the disease is paucibacillary, no single test reliably confirms or excludes it. Diagnosis rests on combining findings.
In practice, when genital TB is suspected, the decisive step is usually direct visualisation — whether you need a laparoscopy and what it involves is worth reading before that conversation, because it also allows biopsy and treatment of adhesions in the same sitting.
Why Genital TB Is Often Over-Diagnosed and Over-Treated
This section exists because patients are rarely told any of it, and because it affects a great many women in India every year.
TB PCR on an endometrial sample is cheap, quick and widely available. It is also prone to false positives. The published position is explicit: a positive PCR alone is not taken as a diagnosis of genital tuberculosis. Yet in practice, a positive PCR frequently results in six to nine months of anti-tubercular treatment being started immediately.
The consequences of getting this wrong are real. Anti-tubercular drugs carry side effects including liver toxicity. Fertility treatment is typically postponed until the course is finished, which for a woman in her late thirties is a meaningful loss of time she cannot recover. And researchers affiliated with India’s own ICMR have written that this pattern of empirical over-treatment is a concern not only for drug toxicity but as a contributing factor in the rise of multidrug-resistant tuberculosis in India.
None of this means anti-tubercular treatment is wrong. Where genital TB is genuinely present, ATT is essential and can be fertility-restoring. It means the diagnosis should be made on a combination of findings — history, imaging, laparoscopic or hysteroscopic appearance, and laboratory results together — rather than on one positive PCR.
So if you are told you need nine months of TB treatment before fertility treatment can begin, these are reasonable questions to ask your doctor:
- What is this diagnosis based on — which specific findings?
- Was anything other than a PCR positive?
- Has a laparoscopy or hysteroscopy been done, and what did it show?
- What happens to my fertility timeline during and after treatment?
- If I am in my late thirties, can any part of the fertility work — such as egg or embryo freezing — proceed alongside?
A good clinician will welcome these questions. Asking them is not a challenge to the doctor; it is the patient doing exactly what the literature says should happen.
Genital TB Treatment: ATT, Surgery and Fertility Options
Anti-Tubercular Therapy (ATT)
The standard treatment uses a combination of drugs — typically rifampicin, isoniazid, pyrazinamide and ethambutol — over roughly six to nine months, sometimes extended to twelve, and longer in drug-resistant disease. ATT eliminates the active infection and reduces inflammation. Completing the full course exactly as prescribed matters enormously: incomplete treatment is how drug resistance develops.
What ATT can do is cure the infection. What it usually cannot do is reverse scarring that has already formed. That is the crucial distinction, and it is why treatment alone does not always restore fertility.
Surgery
Laparoscopic or hysteroscopic surgery can divide adhesions, drain or remove a hydrosalpinx and partially restore anatomy. Tubal surgery to reopen TB-damaged tubes has limited success, because the damage is usually to the delicate internal lining rather than simply a mechanical blockage — which is why IVF is generally preferred over tubal repair in this specific condition. Removing or clipping a hydrosalpinx before IVF, however, meaningfully improves the chance of the cycle working.
Assisted Reproduction
Where damage is permanent, IVF bypasses the tubes entirely, and ICSI with surgical sperm retrieval addresses obstructive azoospermia in men. IUI has a limited role here, since it still requires at least one functioning tube.
Can You Get Pregnant After Genital TB?
Yes — and the honest version of this answer depends on how early it was caught and where the damage is.
A 2025 systematic review of pregnancy outcomes in genital TB found that where anti-tubercular treatment is given in early-stage disease, pregnancy outcomes can be comparable to those achieved with IVF. In advanced disease, IVF produced significantly higher pregnancy rates than ATT alone. And where hysterosalpingography or laparoscopy showed no structural abnormality, pregnancy rates were similar whether conception was spontaneous or through IVF.
Translated: if it is found before the tubes and lining are scarred, treating it may be enough. If it is found after, IVF is the route — and it works. Which is the entire argument for looking earlier.
Does IVF Work After Genital TB? Tubal vs Endometrial Disease
This is the most important table on the page, and the distinction almost nobody explains to patients.
Studies of women with treated endometrial TB have reported cumulative clinical pregnancy rates after IVF similar to non-TB patients, with live birth rates somewhat lower — so the picture is difficult rather than hopeless. And natural pregnancy after a failed IVF cycle does happen, particularly where tubal patency was partially preserved. Because time is a variable in all of this, our discussion of how age affects your chances is worth reading alongside.
Can Genital TB Be Prevented?
Partly. BCG vaccination in infancy offers protection against severe and disseminated tuberculosis in childhood, which reduces the chance of the bacteria seeding distant organs, though it does not fully prevent adult pulmonary or extrapulmonary TB. Treating pulmonary TB promptly and completely is the most effective prevention for genital involvement — every incomplete course is an opportunity for the infection to persist and spread.
Beyond that: good nutrition and general health support immunity, and a full preconception consultation before trying is where a past TB history should be raised, because it is far easier to investigate before a year has been lost. Our guide on the wider role of diet and lifestyle in fertility covers the general groundwork.
If you have ever been treated for TB of any kind, or lived closely with someone who was, say so at your first fertility appointment. It changes what we look for.
When to Raise This With a Doctor
Ask specifically about genital TB if any of the following apply: unexplained infertility with normal basic tests; periods that have become very scanty or stopped; blocked tubes or hydrosalpinx on an HSG; a thin endometrium that does not respond to treatment; repeated implantation failure or recurrent miscarriage; a personal or close family history of tuberculosis of any kind; or, for men, unexplained azoospermia with a scrotal lump or a history of TB.

Genital TB and Fertility Care at Shradha IVF, Patna
Under Dr. Shradha Chakhaiyar, MBBS, DGO, MRCOG (London), genital tuberculosis is something we actively consider rather than reach for last, because in Bihar it belongs on the differential from the beginning.
Our approach at Shradha IVF & Maternity in Patna is to build the diagnosis on a combination of findings rather than a single test — history, imaging, hysterosalpingography, and where indicated diagnostic laparoscopy and hysteroscopy with biopsy, which lets us see the disease directly and treat adhesions in the same procedure. Where genital TB is confirmed, we treat it properly and completely. Where it is not confirmed, we say so plainly rather than starting nine months of treatment on a doubtful result — because for many of the women who come to us, time is the resource in shortest supply.
If you are coming in, our guide on how to prepare for a first consultation lists what to bring. Bring any old TB treatment records — even from years ago, even from a relative’s treatment that you were screened during. They matter more here than almost anywhere else.
The scarring it leaves is what we are racing.
Genital TB and Infertility FAQs
Can TB cause infertility?
Yes. Tuberculosis affecting the reproductive organs, called genital tuberculosis, is a recognised cause of infertility in both sexes. In women it scars and blocks the fallopian tubes, damages the uterine lining and causes pelvic adhesions. In men it can obstruct the epididymis and cause azoospermia. Most affected people never had obvious lung tuberculosis.
What is genital tuberculosis?
Genital tuberculosis is tuberculous infection of the reproductive tract, usually spread through the bloodstream from an earlier lung infection. It is described as paucibacillary, meaning very few organisms are present, which makes it hard to detect. It is frequently silent, and infertility is often the only presenting symptom.
What are the symptoms of genital TB in women?
There may be none at all — infertility is often the only sign. Where symptoms occur they include scanty, irregular or absent periods, chronic pelvic pain, abnormal vaginal discharge, pain during intercourse, and recurrent miscarriage or repeated failed IVF cycles. Classic TB symptoms such as low-grade fever, weight loss and night sweats are frequently absent.
How is genital TB diagnosed?
No single test confirms it. Diagnosis combines history, pelvic ultrasound, hysterosalpingography, endometrial biopsy with histopathology and culture, molecular tests such as GeneXpert, and direct visualisation through laparoscopy and hysteroscopy. A normal chest X-ray does not rule it out, and a positive TB PCR alone is not accepted as diagnostic because of high false positivity.
Can you get pregnant after genital TB treatment?
Yes. Where the disease is caught early and anti-tubercular treatment is given before significant scarring, pregnancy outcomes can be comparable to those achieved with IVF. In advanced disease, IVF produces significantly higher pregnancy rates than treatment alone. Where imaging and laparoscopy show no structural damage, spontaneous conception rates are similar to IVF rates.
Does IVF work if you have had genital TB?
It depends on where the damage is. If only the fallopian tubes are affected and the uterine lining is healthy, IVF bypasses the blockage and outcomes are broadly comparable to other IVF patients. If the endometrium is involved, implantation is the limiting factor, and results are poorer, sometimes requiring hysteroscopic treatment or endometrial preparation first.
Can TB cause infertility in men?
Yes. Male genital tuberculosis most often affects the epididymis, scarring it and blocking the passage sperm travel through, which causes obstructive azoospermia — no sperm in the semen despite normal production. The prostate, seminal vesicles and rarely the testis can also be involved. Surgical sperm retrieval with ICSI is usually effective in these cases.
Is genital tuberculosis contagious?
Genital tuberculosis is not spread through sexual contact in the way sexually transmitted infections are. Tuberculosis spreads through the air from someone with active lung disease. If you have genital TB, you are generally not infectious to a partner, but active pulmonary tuberculosis should be excluded, since that form is transmissible and requires its own treatment.
Genital Infertility? Ask About This One.
Genital TB is one of the most commonly missed causes of infertility in India — and one of the most treatable when found early. A proper evaluation combines several findings rather than relying on one test. First consultations at Shradha IVF & Maternity are free.
