ABSTRACT
OBJECTIVE:
We retrospectively analyzed the correlation between different endometrial preparation protocols and pregnancy outcomes in patients with polycystic ovary syndrome (PCOS) who underwent frozen embryo transfer (FET).METHODS:
A total of 200 PCOS patients who underwent FET were divided into HRT group (n = 65), LE group (n = 65), GnRHa + HRT group (n = 70) according to different endometrial preparation protocols. The endometrial thickness on the day of endometrial transformation, the number of embryos transferred, and the number of high-quality embryos transferred were compared among the three groups. The pregnancy outcomes of FET in the three groups were compared and analyzed, and a further multivariate logistic regression model was used to analyze the factors influencing FET pregnancy outcomes in PCOS patients.RESULTS:
Endometrial thickness on the day of endometrial transformation, clinical pregnancy rate and live birth rate in GnRHa + HRT group were higher than those in the HRT group and LE group. The results of multivariate regression analysis showed that the pregnancy outcome of PCOS patients undergoing FET was significantly associated with the patient's age, endometrial preparation protocols, number of embryos transferred, endometrial thickness, and duration of infertility.CONCLUSION:
Compared with HRT or LE alone, GnRHa + HRT protocol results in higher levels of endometrial thickness on the day of endometrial transformation, clinical pregnancy rate, and live birth rate. Female age, endometrial preparation protocols, number of embryos transferred, endometrial thickness, and duration of infertility are determined as factors influencing pregnancy outcomes in PCOS patients undergoing FET.Palavras-chave
