BACKGROUND: It was our intention to determine whether hysteroscopic polypectomy before intrauterine insemination (IUI) achieved better pregnancy outcomes than no intervention. METHODS: A total of 215 infertile women from the infertility unit of a university tertiary hospital with ultrasonographically diagnosed endometrial polyps (EP) undergoing IUI were randomly allocated to one of two pretreatment groups using an opaque envelope technique with assignment determined by a random number table. Hysteroscopic polypectomy was performed in the study group. Diagnostic hysteroscopy and polyp biopsy was performed in the control group. RESULTS:Total pregnancy rates and time for success in both groups after four IUI cycles were compared by means of contingency tables and life-table analysis. A total of 93 pregnancies occurred, 64 in the study group and 29 in the control group. Women in the study group had a better possibility of becoming pregnant after polypectomy, with a relative risk of 2.1 (95% confidence interval 1.5-2.9). Pregnancies in the study group were obtained before the first IUI in 65% of cases. CONCLUSIONS: These data suggest that hysteroscopic polypectomy before IUI is an effective measure.
