Low day 3 luteinizing hormone values are predictive of reduced response to ovarian stimulation
City Hospital, Buklum Sokak 53, 06660 Kavaklidere, Ankara, Turkey
Dear Sir,
We have read with great interest the paper by Noci et al. (Noci et al., 1998
), indicating that day 3 luteinizing hormone (LH) values <3 mIU/ml are predictive of poor response to ovarian stimulation in patients with normal basal follicle stimulating hormone (FSH) concentrations. In this study, no in-vitro fertilization (IVF) patients were included and patients treated by intrauterine insemination, direct intraperitoneal insemination and timed spontaneous intercourse were chosen as the study population (LH<3 mIU/ml, n = 30) or controls (LH>3 mIU/ml, n = 45). They found that the oestradiol peak and the number of follicles >15 mm diameter at the time of human chorionic gonadotrophin
