Genital tuberculosis in women reaches the genital tract predominantly by which route?

• A Direct contiguous spread from bowel
• B Haematogenous spread from a pulmonary or other primary focus ✓
• C Lymphatic spread from inguinal nodes
• D Ascending infection via the vagina during intercourse

Explanation

Female genital tuberculosis is almost always secondary, with Mycobacterium tuberculosis reaching the tubes haematogenously from a primary focus, most commonly the lung, which may itself be quiescent or healed. The tubes are infected first, followed by the endometrium. Sexual transmission producing primary vulval or vaginal tuberculosis is described but is exceedingly rare.
