Effect of Three Androgen Indexes (FAI, FT, and TT) on Clinical, Biochemical, and Fertility Outcomes in Women with Polycystic Ovary Syndrome.

This work sought to evaluate the effects of three androgen indexes of free testosterone (FT), total testosterone (TT), and free-androgen index (FAI) on clinical phenotype, endocrine metabolic disorders, and fertility outcomes in women with polycystic ovary syndrome. The data in this study came from a large, multicenter, randomized double-blind controlled clinical trial involving 1000 infertile PCOS patients. Baseline phenotypic, endocrine, and metabolic parameters and fertility outcomes undergoing ovulation induction were collected. FAI is superior to FT, and FT is superior to TT in terms of their correlation with anthropometric parameters and metabolic profile. FT and TT were significantly positively correlated with LH/FSH. FAI and FT were significantly correlated with the incidence of metabolic syndrome. FAI, FT, and TT were significantly positively correlated with polycystic ovary morphology and menstrual period. FAI was significantly related ovulations per cycle, pregnancy, conception, and live birth rates. After adjusting for age, the increased FT level was significantly related to the decreased rates of ovulations per cycle, conception, and pregnancy. FAI is superior to FT and FT is superior to TT in terms of their correlation with phenotypic and metabolic parameters in PCOS patients. FAI and FT are important factors related to the fertility outcomes of infertile PCOS patients. Clinical trial registration number: NCT01573858.
