A total of 848 couples attended our infertility clinic over a period of 4 years. Two hundred forty-eight complained of secondary infertility of which 63.7% had an abnormal hysterosalpingographic finding. The abnormal hysterosalpingography (HSG) was seen to increase with an increase in age and duration of infertility. Of the subjects with previous viable delivery, 41.6% had normal HSG whereas 38.1% with previous spontaneous abortion and only 11.5% with previous induced abortion had a normal HSG. Uterine abnormality was 2 and a half times in the cases with spontaneous abortion than in cases who had previous viable delivery. Tubal blocks were detected more in secondary infertility group whereas congenital uterine abnormalities were more in primary infertility group. Bilateral tubal blocks were more common in cases who had an abortion followed by sepsis.
