Abstract

OBJECTIVE:

This retrospective study was conducted to explore causes of unsynchronized follicular maturation (UFM) and analyze the effects of large follicle puncture on embryo quality and pregnancy outcome.

METHODS:

Clinical features and controlled ovulation hyperstimulation (COH) were compared between the puncture group (n = 48) and the control group (n = 2545). We analyzed the COH process with in vitro fertilization during fresh cycle embryo transfer with different clinical pregnancy outcomes. We compared clinical characteristics and COH process of patients in the clinical pregnancy (n = 774) and non-clinical pregnancy (n = 527) groups. Finally, factors related to pregnancy outcomes were analyzed using multivariate logistic regression analysis.

RESULTS:

Age, level of estradiol on down-regulation day, and initial gonadotropin dose were significantly higher in the puncture group than in the control group. We detected significant differences in age, infertility, and body mass index (BMI) between the clinical and non-clinical pregnancy groups. Age, BMI, and endometrial thickness on the day of human chorionic gonadotropin administration were the independent factors influencing pregnancy outcome.

CONCLUSIONS:

Patient's age and level of anti-Müllerian hormone were the main factors causing UFM in patients undergoing COH. Large follicle puncture had no significant effect on pregnancy outcome.
