Abstract

Purpose: It is well known that androgen excess impairs oocyte quality, endometrial receptivity and even embryo invasion to some extent. Free androgen index (FAI) is strongly recommended to evaluate active androgen. Previous studies have showed conflicting conclusions on the effect of hyperandrogenism on the pregnancy outcomes in patients with polycystic ovary syndrome (PCOS). This study aims to analyze the influence of hyperandrogenemia based on FAI on frozen embryo transfer (FET) outcomes in patients with PCOS.

Patients And Methods: Patients diagnosed with PCOS who underwent their first FET between January 2017 and April 2022 were stratified into two cohorts using FAI, a highly recommended parameter: PCOS with hyperandrogenemia (n=73) and PCOS without hyperandrogenemia (n=255). Basic and infertility characteristics were analyzed using Student's -test or chi-square (χ2) statistics. Logistic regression analysis was performed to verify whether FAI was helpful in predicting pregnancy outcomes in women with PCOS.

Results: Body mass index (BMI), total gonadotropin (Gn), basal serum follicle-stimulating hormone (bFSH), basal serum testosterone (bT), sex hormone binding globulin (SHBG), and FAI were significantly different between the two groups. (=0.005, <0.001, <0.001, <0.001, and <0.001, respectively). However, clinical pregnancies, abortions, and live births did not differ significantly. Further regression analyses showed that FAI was not related to clinical pregnancy, abortion, or live birth rates (adjusted odds ratio (OR)=0.978, 95% confidence interval (CI)=0.911-1.050, =0.539; adjusted OR=1.033, 95% CI=0.914-1.168, =0.604; and adjusted OR=0.976, 95% CI=0.911-1.047, =0.499, respectively).

Conclusion: FAI was not associated with pregnancy outcomes in patients with PCOS; that is, it did not reflect any negative effects of hyperandrogenemia on pregnancy outcomes in patients with PCOS and was not an informative clinical parameter. Therefore, more attention should be paid to the factors that influence the accuracy of FAI in reflecting androgen levels in vivo, and further discussion is needed.
