One hundred thirteen couples with either male factor, cervical factor, endometriosis, or idiopathic infertility of at least 3 years' duration were treated by intrauterine insemination (IUI) of washed motile sperm. Of the 68 women who became pregnant or completed at least three cycles of insemination, the overall pregnancy rate was 38.2%, with a mean of 1.7 treatment cycles per pregnancy. The average pregnancy rate per treatment cycle was 11.4%. Women who did not become pregnant underwent an average of 4.7 treatment cycles. Importantly, only two pregnancies occurred independent of treatment in 113 couples. In the male factor group, the pregnancy rate was 42.9% (n = 21). In women with a cervical factor, 34.5% became pregnant (n = 29); in idiopathic infertile couples or women suffering from endometriosis, there was a pregnancy rate of 38.9% (n = 18). The presence of sperm antibodies in either the male or female partner significantly lowered the pregnancy rate (6.7%) when compared with couples without sperm antibodies (50.0%). The authors conclude from these observations that IUI with washed sperm is a successful mode of therapy, especially in the case of males with asthenozoospermia.
