This research paper presents the results of ovarian reserve estimation for 125 women with the Polycystic Ovary Syndrome (PCOS) who have undergone various methods of surgical treatment resection of the ovaries, thermokauterisation and drilling by laser (HoYag). Ovarian reserve was estimated according to the amount of antral follicles, level of follitropin and Müllerian inhibiting substance (MIS), also named antiMüllerian hormone (AMH). Blood flow in ovarian tissue was also examined after various methods of surgical treatment. The study has shown that the gentlest method of surgical treatment is drilling by HoYag laser, which is least likely to injure the tissue of ovaries, and also this method is most effective in enhancing and preserving ovarian reserve., Vasiliy Simrok, Daria Simrok-Starcheva, and Literatura
