A study on Trichomoniasis vaginalis and female infertility.

A total of 280 patients, 240 infertile and 40 pregnant were subjected to thorough history taking, general and local examination for exclusion of organic lesion, laboratory investigations to exclude parasitic, bacterial and fungal infections. Sterile vaginal swab from the posterior fornix was taken, and examined by wet smear preparation, Giemsa staining and cultivation on C.P.L.M. medium for trichomoniasis infection. The mean age of the infertile group was 25.75+/-3.92, and of the control group was 21.6+/-2.38 (in years). The mean duration of infertility was 2.81+/-1.51 (years). Out of 240 infertile women, 18.75% complained of discharge, 17.5% itching, 15.42% dysuria, 14.58% dyspareunia, and 10% had cervical lesion. Of the 40 controls, 5% complained of discharge, 2.5% complained of itching, dysuria, dyspareunia, but none had cervical lesion. Of the total cases (280), 36 (12.9%) had T. vaginalis. The clinical data observed were significantly higher among the infertile group than the control group. Cultures were positive in 14.58% of the infertile group and 2.5% in the control group. The difference between the 2 groups was statistically significant. No doubt, T. vaginalis plays an important role in female infertility.
