Objective — to give a comparative assessment of the state of the ovarian reserve in patients after laparoscopic removal of endometrioid ovarian cysts with the use of bipolar coagulation and without using surgical energies, using hemostatic matrices. Material and methods. The study included 133 patients with infertility and the presence of an ovarian endometrium who underwent laparoscopic cystectomy using two methods of intraoperative hemostasis: group 1 — 75 patients underwent bipolar coagulation, 2nd group — 58 patients using hemostatic matrices. All patients underwent a study of the main parameters of the ovarian reserve before and after the operation: AMG, FSH and the number of antral follicles. Results. To compare the groups by the quantitative parameters after the operation, a nonparametric Mann—Whitney test was used. When studying the effect of the operation type on the studied parameters, it was revealed that the groups differ in the level of AMH (p=0.029), FSH level (p=0.049), and in the number of follicles in the operated ovary (p=0.0008). According to the number of follicles in the ovary in the study, the groups were not statistically significantly different (p=0.15). Median level of AMG when using hemostatic matrices is 1.72 (0.6; 2.7) ng/ml, and when using coagulation –1.2 (0.4; 2.0) ng/ml. Significant differences were also revealed after the operation and FSH levels in the blood serum: in group 1 of FSH — 7.4 (5.3; 11.2) IU/l, in the second group of FSH — 7.1 (4.6; 8.4) IU/l. Conclusion. The use of modern hemostatic matrices for the purpose of hemostasis during surgical treatment of the ovarian endometrioma has a smaller negative effect on the main indicators of the ovarian reserve than classical operational techniques using bipolar coagulation.
