title: Intrauterine insemination treatment in subfertility: an analysis of factors affecting outcome.
abstract: A total of 811 intrauterine insemination (IUI) cycles in which clomiphene citrate/human menopausal gonadotrophin (HMG) was used for ovarian stimulation were analysed retrospectively to identify prognostic factors regarding treatment outcome. The overall pregnancy rate was 12.6% per cycle, the multiple pregnancy rate 13.7%, and the miscarriage rate 23.5%. Logistic regression analysis revealed five predictive variables as regards pregnancy: number of the treatment cycle (P = 0.009), duration of infertility (P = 0.017), age (P = 0.028), number of follicles (P = 0.031) and infertility aetiology (P = 0.045). The odds ratios for age < 40 years, unexplained infertility aetiology (versus endometriosis) and duration of infertility < or = 6 years were 3.24, 2.79 and 2.33, respectively. A multifollicular ovarian response to clomiphene citrate/HMG resulted in better treatment success than a monofollicular response, and 97% of the pregnancies were obtained in the first four treatment cycles. The results indicate that clomiphene citrate/HMG/IUI is a useful and cost-effective treatment option in women < 40 years of age with infertility duration < or = 6 years, who do not suffer from endometriosis.
