PurposeTo investigate the effects of metabolic abnormalities, hyperandrogenemia and ovulation induction by clomiphene/acupuncture on liver function parameters among women with polycystic ovary syndrome (PCOS).MethodsThis is a secondary analysis of a randomized controlled trial. All 1000 subjects were diagnosed as PCOS by modified Rotterdam criteria. Liver function parameters, metabolic panel and hormone profile were measured at baseline and after treatment. The relationship between liver parameters with metabolic, hormonal parameters and ovulation induction was examined.ResultsPCOS women with metabolic syndrome had higher liver enzyme levels but lower bilirubin and bile acid levels than without. PCOS women with hyperandrogenemia had higher liver enzyme, bilirubin levels than without. Correlation analyses showed that worsening of metabolic parameters was associated with higher liver enzyme levels but lower bilirubin and bile acid levels, while increased androgen levels were associated with higher liver enzyme, bilirubin and bile acid levels. Ovulation induction with clomiphene citrate could decrease bilirubin and bile acid levels, while acupuncture had no obvious effect on liver function.ConclusionsAmong PCOS women, metabolic abnormalities and hyperandrogenemia impaired different liver function parameters. Clomiphene could decrease the bilirubin and bile acid levels while acupuncture had no obvious effect on liver function.
