Cumulative pregnancy rates and probability of pregnancy in various indications for intrauterine insemination

A total of 122 patients were evaluated in a retrospective study for the cumulative pregnancy rate after intrauterine insemination. The indications included idiopathic infertility, anovulation, male factor, poor postcoital test, endometriosis, and pelvic factor. The cumulative pregnancy rate by 3 cycles or less varied from 7.7 to 43.5%. The highest pregnancy rate was for the group with poor postcoital test. There was no increase in pregnancy rate after 3 cycles of treatment. The concentration and motility of sperm were not significantly different between pregnant and nonpregnant groups.
