Abstract:

AIM: To investigate the effect of intrauterine injection of human chorionic gonadotropin (hCG) upon pregnancy outcomes following frozen-thawed embryo transfer (FET) for endometriosis (EMs) patients. METHODS: We retrospectively collected 228 FET cycles of EMs patients, and divided them into intrauterine injection group (50 cycles) and control group (178 cycles). Age, infertile duration, body mass index, hormone profile, endometrial thickness, embryo quality, clinical pregnancy rate and live birth rate were compared, the related factors affecting live birth were further analyzed. RESULTS: No significant difference was detected when baseline character, hormone change, endometrial thickness and embryo quality were compared between two groups, while live birth rate was found statistically higher and miscarriage rate was remarkably lower in intrauterine injection group. Age and intrauterine injection of hCG were two independent factors affecting live birth in EMs following FET. CONCLUSION: Intrauterine injection of hCG prior to FET can improve the live birth rate and reduce the miscarriage rate for EMs patients.
