In female genital tuberculosis, the infection reaches the genital tract PRIMARILY by which route, and which organ is affected FIRST?

• A Lymphatic spread from inguinal nodes, vulva first
• B Haematogenous spread from a pulmonary focus, fallopian tubes first ✓
• C Direct contiguous spread from bowel, uterus first
• D Ascending sexual transmission, cervix first

Explanation

Genital tuberculosis is almost always secondary, reaching the genital tract haematogenously from a primary focus, most often the lung, frequently reactivating around puberty when pelvic vascularity increases. The fallopian tubes are affected first in nearly all cases because of their rich arterial supply, followed by the endometrium in about half of cases. Lymphatic and direct spread occur but are uncommon routes.
