Intrauterine insemination with husband's Percoll preparated sperm was performed in 179 couples in a total of 440 treatment cycles. A total of 60 pregnancies was obtained. The pregnancy and delivery rate was 13.6% and 9.3% per insemination cycle, respectively. The cumulative probabilities of pregnancy and delivery were respectively 42% and 31% after three cycles. There was a significantly higher pregnancy rate when the number of follicles was more than three and a trend towards more pregnancies when the number of spermatozoa was increased. The study shows that this easy and non-invasive treatment gives acceptable results. We recommend an ideal maximum of three treatment cycles, and at least 1-2 million spermatozoa for each insemination.
