ovarian reserve in women of late reproductive age by the method of treatment of pcos

background: the prevalence of polycystic ovarian syndrome (pcos) particularly is increased in adolescents. very few longitudinal follow-up for assessment of ovarian reserve in women of late reproductive age with previously confirmed pcos have been conducted, especially after its diagnosis and treatment in adolescence. objective: the aim of the present study was to compare of the ovarian reserve of the women of late reproductive age by the method of treatment of pcos in adolescence. materials and methods: this cross sectional study in an unselected population was conducted from january to june 2014. a total of 123 women of late reproductive age were included. they had been diagnosed with pcos between 1984 and 1990 when they were 13-18 yr. from these, first group of the study was consisted of 67 participants who underwent conservative treatment with antiandrogens and combined oral contraceptives and second group of the study was consisted of 56 participants after surgery (34-bilateral ovarian drilling and 22- ovarian wedge resection). at the time of investigation patients were 35-45 yr. the participants were collected via analysis of histories at primary diagnosis of pcos in adolescence and at the time of the investigation analyses of reproductive hormones were conducted. data were compared between the groups. results: after conservative treatment pcos women had higher levels of anti- mullerian hormone and lower follicle-stimulating hormone levels (p=0.02 and p=0.04, respectively). the number of antral follicles and mean ovarian volume were significantly greater also, than in women who underwent surgical treatment (p=0.03 and p=0.04, respectively). conclusion: our data suggest that pcos patients who underwent conservative treatment have the better ovarian reserve than women who underwent surgical treatment of pcos in adolescence.
