Résumé
To determine the frequency of different causes responsible for subfertility in our setup. Prospective cross-sectional study from March 2005 to March 2006. Oupatients Dept. [OPD] of Gynaecology and Obstetrics [Unit 111], Civil Hospital, Karachi. All patients who were diagnosed as subfertile. Amongst the 156 women included in the study, 85 [54.5%] had primary and 71 [45.6%] secondary subfertility. Majority [59%] of cases were between 21-30 years of age; 78 [50%] complained of subfertility only, while 26 [17%] had history of vaginal discharge, 34 [21%] menstrual disorders and 12 [8%] weight gain. Nineteen [14%] cases had family history of subfertility, 18 [12%] of congenital anomaly and 3[2%] of genetic disorders. Abnormal hormonal profile was seen in 37 [27%] patients, whereas 63 [40.3%] had positive findings on pelvic ultrasound and 43 [27%] patients tubal blockage on hysterosalphinography. Out of 156 women, 27 [17.3%] had Ovarian factor in the form of anovulation, polycystic ovarian syndrome and premature ovarian failure and 51 [32.7%] had Tubo-Ovarian factor in the form of tubal blockage, endometriosis, endometritis and uterine fibroid; in 19 [12.2%] cases both the partners had abnormality, in 40 [25.6%] the male partners had semen abnormality [25.6%], while in 19 [12.2%] no cause could be found. A significant number of patients had secondary subfertility, mostly due to previous surgical interventions, and were suffering from anaemia and vaginal infection. Tubal blockage and male factors were the predominant causes of subfertility
