Abstract
Introduction
Polycystic ovary syndrome (PCOS) is a common endocrine disease among women in the reproductive age that is associated with consequences such as insulin resistance and hyperandrogenemia. This study was aimed to assess the association of sex hormone profile and kisspeptin levels in PCOS women in Gorgan, Iran.
Methods
In this case-control study, 43 women with diagnosed PCOS between the ages of 15 and 37 years and 40 healthy demographically matched controls were recruited. Sex hormone profile and kisspeptin levels were measured in these subjects using ELISA assay kits.
Results
Follicle stimulating hormone (FSH), sex hormone binding globulin (SHBG), and kisspeptin levels were significantly lower in cases than in controls. Luteinizing hormone (LH), free-testosterone (FT), 17-OH-progesterone (17-OH-P), dehydroepiandrosterone sulfate (DHEA-S), estradiol (E2), and free androgen index (FAI) were higher in PCOS significantly. There was a significant positive correlation between kisspeptin levels and LH and E2 in cases (p = 0.037 and p = 0.024, respectively). The results of the regression analysis have shown a significant association between the LH and kisspeptin concentrations in PCOS group (r = 0.275, p = 0.037).
Conclusion
PCOS patients had lower plasma kisspeptin level that was positively correlated with LH and estradiol levels. Also, higher levels of free androgens were demonstrated in these patients. It is suggested that kisspeptin may be involved in complex interactions of the sex hormone endocrine system of PCOS.
