Due to ESHRE criteria (2011) 150 infertile women of IVF department were divided into the group of cases with POR and the control group with the normal ovarian response. The elder age of the women and the earlier age of menopause in their mothers seemed to be the significant risk factors of POR. Also POR was associated with the history of abortions, ovarian stimulation, and hormonal contraception. Ovarian stimulation protocol did not influence the number of follicles and oocytes in both case and control groups. The pregnancy rate was higher in patients with GnRH antagonists protocol.poor ovarian responselow ovarian reserveassisted reproductive technologies (ART)in vitro fertilization (IVF)protocol of GnRHaprotocol of GnRH-ant«бедный» овариальный ответснижение овариального резервавспомогательные репродуктивные технологииэкс- тракорпоральное оплодотворениепротокол с агонистами гонадотропин-рилизинг-гормонапротокол с антагонистами гонадотро- пин-рилизинг-гормона[Ulug U, Ben-Shlomo I, Turan E.
