Abstract：Objective To explore the impacts of natural ovulation cycles and stimulation cycles on the outcome of intrauterine insemination (IUI) in order to improve the clinical effects of IUI. Methods 176 women received 384 stimulation cycles. According to different ovulation stimulation protocols , the women were divided into six groups including natural cycle (NC) group, clomiphene citrate (CC) group, letrozole (LE) group;human menopausal gonadotrophin (HMG ) group, CC + HMG group, and LE + HMG group. The pregnancy rate between nature cycles and ovarian hyperstimulation cycles was compared. Results The pregnancy rate was 9.33%in the nature cycle group and 13.27% in the stimulation cycle group, with a significant difference (P < 0.05);and it dif not differ significantly among the stimulation cycle groups (P > 0.05). Conclusions Use of ovulation-induction medications is one of the important factors affecting the pregnancy rate of intrauterine insemination. There are no differences in the outcome of IUI among different ovulation stimulation protocols.
