Female genital tuberculosis and infertility

Objectives: This study was performed to evaluate the rate of diagnosed female genital tuberculosis and its presentational symptoms and methods of diagnosis. Methods: A total of 3088 cases of tuberculosis (TB) who had been registered and treated in the Health Center of Fars Province from 1989 to 1999 were retrospectively studied. From this group, 46 women were diagnosed as having genital TB. The diagnosis in 41 cases was based on the standard pathological criteria of tissue specimens. The other five cases were excluded from this study due to the lack of classical diagnostic criteria. Statistical analysis was performed using the Z-test. Results: The mean age of the patients at the time of diagnosis was 30.4 years. Seven patients presented with abdominal or pelvic pain (17.07%). In this group three cases underwent laparatomy due to abdominal mass and four patients for tubo-ovarian abscess, which led to the diagnosis. Abnormal uterine bleeding was the cause of diagnostic dilatation and curettage in three other patients (7.31%). However, in 31 cases (75.6%) TB was diagnosed during studies performed to evaluate the cause of their infertility, and the most common diagnostic procedure was endometrial curettage (25 cases). Female genital TB accounted for 1.32% of all tuberculous patients in this study. Of these, 75.6% were infertile by definition (Z = 12.13 P < 0.0001). TB endometritis was detected in 72.03%, tubal involvement in 34.03%, ovarian TB in 12.9% and cervical TB in 2.4% of the patients. Conclusions: This study confirms the presence of a strong relationship between genital TB and infertility; therefore genital TB would be more frequently diagnosed if this possibility was considered in the evaluation of every infertile patient in areas where tuberculosis is endemic.
