Satisfactory results following in vitro fertilization-embryo transfer (IVF-ET) treatments depend on retrieving an appropriate number of mature oocytes without causing the development of ovarian hyperstimulation syndrome (OHSS). The present study was carried out to investigate whether the ovarian reserve is predictable based on the day-3 serum concentration of follicle stimulating hormone (FSH) during the pituitary suppression cycle using a gonadotropin releasing hormone (GnRH) agonist (defined as day-3 FSH) in patients undergoing IVF-ET treatment. Day-3 FSH before the administration of gonadotropin was assessed in 72 IVF-ET cycles from 59 infertile women. The mean ± SD of day-3 FSH, the total amount of FSH plus human menopausal gonadotropin (hMG) administered, and the total number of oocytes retrieved was 5.5 ± 2.6 mIU/ml, 2834.2 ± 1236.5 IU and 7.7 ± 5.8, respectively. There were significant correlations between day-3 FSH and the total amount of FSH-hMG administered (p < 0.001), and day-3 FSH and total number of oocytes retrieved (p < 0.001). There was a significant difference of day-3 FSH between patients who subsequently conceived (4.4 ± 1.3 mIU/ml) and those who did not conceive (6.1 ± 2.9 mIU/ml) (p = 0.001). There was also a significant difference of day-3 FSH between patients who developed moderate or severe OHSS (4.5 ± 1.2 mIU/ml) and those who did not (5.9 ± 2.8 mIU/ml) (p = 0.003). Receiver-operator characteristic curve analysis showed that the significant cut-off point for day-3 FSH for predicting ovarian reserve was 5.25 mIU/ml. These findings indicate that day 3-FSH is useful for predicting ovarian reserve during the pituitary suppression cycle using a GnRH agonist in patients undergoing IVF-ET.
