Abstract
Ovary is the main source of the hyperandrogenism in polycystic ovary syndrome (PCOS). Adrenal glands may also be involved in the pathogenesis of the development of PCOS. To investigate this possibility and to find out if buserelin test is able to distinguish PCOS patients from the patients with idiopathic hirsutism (IH), ACTH and buserelin tests were performed in 29 women with PCOS, 21 women with IH, and 20 control subjects (CS). We also aimed to determine the role of dysregulation of 17 hydroxylase in the development of PCOS.
Basal and stimulated dehydroepiandrosterone sulfate (DHEA-S) and stimulated cortisol (F) levels after ACTH administration were significantly higher in PCOS group than in IH and CS groups (p < 0.0001 and p < 0.05, respectively). PCOS patients also possessed significantly higher basal and stimulated 17-hydroxyprogesterone (17-OH P) levels, including the peak levels (p < 0.02), during buserelin testing when compared with IH patients and CS. There was no significant correlation between the ACTH-stimulated and the buserelin-stimulated peak 17-OH P values.
In conclusion, significantly higher basal and ACTH-stimulated levels of F and DHEA-S in PCOS compared with controls and patients with IH, reflect that adrenal hyperactivity also plays a role in hyperandrogenemia seen in PCOS. Because of the lack of the correlation between ACTH-stimulated and buserelin-stimulated 17-OH P levels, it is hard to say that adrenal hyperactivity seen in PCOS is the result of the dysregulation of cytochrome P450c17-α enzyme. Our results suggest that buserelin test which is an GnRH analogue could distinguish at least some of the patients with PCOS from the other patients presenting with the common symptoms of hyperandrogenemia.
