Abstract To investigate the influence of intrauterine insemination (IUI) timing on pregnancy outcomes. Methods: The data of 500 women with the first intrauterine artificial insemination of husband semen (AIH) were collected and analyzed. The women were divided into group A (260 cases were given AIH before ovulation), group B (139 cases were given AIH after ovulation), and group C (101 cases were given AIH before and after ovulation). The pregnancy outcomes were compared among the three groups. Results: After treatment, the biochemical pregnancy rate and clinical pregnancy rate of women in group C were 22.8% and 17.8%, which were significant higher than those (15.0% and 11.9%) of women in group A and those (15.8% and 11.5%) of women in group B (P<0.05), while which had no significant different between group A and B (P>0.05). There was no significant different in the abortion rate (11.1%，12.5%，and 12.9%) among the three groups (P>0.05). There were no significant difference in biochemical pregnancy rate, clinical pregnancy rate, and abortion rate between women with natural cycle and the women with ovulation induction cycle (P>0.05). There was no significant difference in biochemical pregnancy rate, clinical pregnancy rate and abortion rate of women in each group of the three groups between women with natural cycle and the women with ovulation induction cycle (P>0.05). Conclusion: AIH before ovulation and AIH after ovulation have the same clinical rate, but two times AIH before and after ovulation can improve the success rate of pregnancy.
