Hormonal contraception is widely used among women worldwide; 50-89% of all women in the Western countries use oral contraception at some point in their lives. Oral contraceptives (OC) suppress the hypothalamic-pituitary-ovarian axis through a negative feedback of ethinyl estradiol and progestins and thereby potentially influence the markers of ovarian reserve due to a suppressed release of gonadotropins, which will impair the growth of antral follicles.
