Genital Tuberculosis

What Is Genital Tuberculosis?

Genital Tuberculosis (GTB) is a bacterial infection that affects the reproductive organs in both men and women. It is a form of “secondary tuberculosis,” meaning the infection usually starts elsewhere in the body (typically the lungs) and spreads to the genital tract through the bloodstream or lymph nodes.

How GTB Develops

The bacteria responsible for TB, Mycobacterium tuberculosis, can remain dormant (inactive) in the body for years after an initial infection. When the body’s immunity weakens, these bacteria can travel to the reproductive organs. In women, it most commonly affects the fallopian tubes and the uterus. In men, it affects the epididymis and testes.

Is GTB Common?

Yes, particularly in India. India has a high prevalence of tuberculosis, and Genital TB is one of the leading, often silent, causes of infertility. It is estimated that a significant percentage of women seeking IVF treatment in India have underlying, undiagnosed genital tuberculosis.

Causes of Genital Tuberculosis

How TB Spreads

TB is primarily an airborne disease spread through droplets when an infected person coughs or sneezes. Once the bacteria enter the lungs, they can enter the bloodstream and settle in the genital organs. It is important to note that Genital TB itself is generally not transmitted through sexual contact.

Risk Factors

You may be at higher risk if you have:

• A history of pulmonary (lung) tuberculosis.
• A weak immune system.
• Close contact with someone who has active TB.
• Live in crowded environments with poor ventilation.
• Malnutrition or poor diet.

Symptoms of Genital Tuberculosis

One of the biggest challenges with GTB is that it is often “silent” (asymptomatic). Many patients do not look or feel sick.

Symptoms in Women

• Infertility: The most common sign.
• Menstrual Irregularities: Scanty periods (Hypomenorrhea) or complete absence of periods (Amenorrhea).
• Pelvic Pain: Chronic, dull pain in the lower abdomen.
• Unusual Discharge: Persistent vaginal discharge that may be blood-stained.
• General Health: Unexplained weight loss, low-grade fever in the evenings, or fatigue.

Symptoms in Men

• Swelling: Painful or painless swelling in the scrotum (testicles).
• Ejaculation Issues: Low semen volume or painful ejaculation.
• Infertility: Difficulty fathering a child due to blockages.
• Blood in Semen: A condition known as hematospermia.

Complications of Genital Tuberculosis

Effects on Fertility

GTB is destructive to reproductive health.

• In Women: It causes severe scarring in the fallopian tubes (blocking them) and thins the uterine lining (endometrium), making it impossible for an embryo to implant.
• In Men: It causes blockages in the tubes that carry sperm (vas deferens), leading to Azoospermia (zero sperm count).

Long-Term Health Risks

If left untreated, GTB can lead to permanent destruction of the ovaries or testes, chronic pelvic pain, and increased risk of ectopic pregnancy (pregnancy growing outside the uterus) due to tubal damage.

Diagnosis of Genital Tuberculosis

At Ferty9, we use a multi-step approach because GTB is notoriously difficult to detect.

Medical History & Physical Exam

We review your past history of TB or exposure to family members with TB. A physical exam checks for tenderness or swelling in the reproductive organs.

Lab Tests

• TB-PCR: An advanced DNA test to detect the presence of TB bacteria.
• Blood Tests: To check for infection markers (like ESR) and latent TB (Mantoux test, though this is less specific for genital TB).

Imaging Tests

• Ultrasound: To check for a thin uterine lining or fluid in the tubes.
• HSG (Hysterosalpingogram): An X-ray to check if the fallopian tubes are blocked or damaged.

Endometrial Biopsy & Hysteroscopy

• Biopsy: Taking a small tissue sample from the uterus lining during the pre-menstrual phase is the most reliable way to test for GTB.
• Hysteroscopy/Laparoscopy: A camera procedure to look directly at the organs. TB often leaves visible white spots (tubercles) or adhesions that confirm the diagnosis.

Genital Tuberculosis & Infertility

How GTB Affects Female Fertility

The bacteria primarily attack the fallopian tubes, causing “hydrosalpinx” (tubes filled with fluid) and irreversible blockages. It also damages the endometrial lining, preventing the uterus from supporting a pregnancy (Asherman’s Syndrome).

How GTB Affects Male Fertility

It causes obstruction in the epididymis and vas deferens. While sperm production may still happen in the testes, the sperm cannot come out, resulting in a low or zero sperm count in the ejaculate.

Can Pregnancy Happen After Treatment?

• Natural Conception: This is difficult if the fallopian tubes are severely damaged.
• IVF (In Vitro Fertilization): This is the most successful route for women with treated GTB. By bypassing the blocked tubes, we can implant an embryo directly into the healed uterus.

Treatment for Genital Tuberculosis

Anti-TB Medications

The standard treatment is a course of antibiotics known as ATT (Anti-Tubercular Therapy). This involves a combination of drugs (like Rifampicin, Isoniazid, etc.) to kill the bacteria.

Duration of Treatment

Treatment is long-term, typically lasting 6 to 9 months. It is crucial to complete the full course even if symptoms disappear, to prevent the bacteria from becoming drug-resistant.

Surgical Treatment (Rare Cases)

Surgery is generally avoided for active TB. However, after medication, surgery may be needed to repair scar tissue in the uterus (hysteroscopic adhesiolysis) or to remove damaged fallopian tubes before IVF to improve success rates.

Prevention of Genital Tuberculosis

General Prevention Tips

• Maintain a healthy immune system through good nutrition.
• Ensure proper ventilation in living spaces.
• The BCG vaccine given at birth protects against severe forms of TB.

Preventing TB Spread

The best prevention is the early treatment of pulmonary (lung) TB. If you have a persistent cough or fever, seek medical help immediately to prevent the infection from spreading to other organs.

When to See a Doctor

Warning Signs

Consult a specialist at Ferty9 if you have:

• Been trying to conceive for over a year without success.
• Very light or absent periods.
• Chronic lower abdominal pain.
• A past history of TB infection.

Summary

Genital Tuberculosis is a major, often hidden hurdle in Indian fertility care. While it can cause significant damage to the reproductive system, it is treatable. With a timely diagnosis, a full course of medication, and advanced fertility treatments like IVF, parenthood is still very much possible. Ferty9 is dedicated to guiding you through this diagnosis with expert care and compassion.
