OBJECTIVE: To analyze the factors affecting clinical pregnancy rate of intrauterine insemination in Center of Reproductive Medicine, Peking University Third Hospital, to guide clinical treatment.
METHODS: In the study, 5 167 intrauterine insemination cycles were retrospectively analyzed from May 2011 to October 2012 in our reproductive center. The data were collected, the single-factor was analyzed with χ2 test, and the multi-factor was analyzed with Logistic regression with a significant level of 0.05.
RESULTS: The cycle clinical pregnancy rate was 12.8%, which decreased with the increase of the female age and infertile duration. The clinical pregnancy rate was low when the sperm density was less than 1×10(6)/mL. In the ovulation group, the clinical pregnancy rate was higher than the natural group. The group with more than 2 dominant follicles had higher clinical pregnancy rate as compared with the single dominant follicle group. The clinical pregnancy rate was the highest in the third cycle but decreased after the fourth cycle. The clinical pregnancy rate was higher in cervical factors, sexual dysfunction, and polycystic ovary than in the group with other reasons.
CONCLUSION: The female age, infertile duration, ovarian stimulation and follicle number, cause of infertility were the main factors affecting clinical pregnancy outcome; the sperm density, and cycle numbers have influence too; the insemination timing, and frequency have little effect.
