  ABSTRACT: In 2009 anti-Müllerian hormone (AMH) assay was approved for clinical use in Korea. This study was performed to determine the reference values of AMH for predicting ovarian response to controlled ovarian hyperstimulation (COH) using the clinical assay data. One hundred sixty-two women who underwent COH cycles were included in this study. We collected data on age, basal AMH and FSH levels, total dose of gonadotropins, stimulation duration, and numbers of oocytes retrieved and fertilized. Blood samples were obtained on cycle day 3 before gonadotropin administration started. Serum AMH levels were measured at a centralized clinical laboratory center. The correlation between the AMH level and COH outcomes and cut-off values for poor and high response after COH was analyzed. Concentration of AMH was significantly correlated with the number of oocytes retrieved (OPU; r=0.700, p<0.001). The mean±SE serum AMH levels for poor (OPU≤3), normal (4≤OPU≤19), and high (OPU≥20) response were 0.94±0.15 ng/mL, 2.79±0.21 ng/mL, and 6.94±0.90 ng/mL, respectively. The cut-off level, sensitivity and specificity for poor and high response were 1.08 ng/mL, 85.8%, and 78.6%; and 3.57 ng/mL, 94.4%, and 83.3%, respectively. Our data present clinical reference values of the serum AMH level for ovarian response in Korean women. The serum AMH level could be a clinically useful predictor of ovarian response to COH.

  ABSTRACT: During stimulated IVF cycles, up to 15% of oocytes are recovered as immature. The purpose of this study was to investigate the trend of oocyte maturity in repeated ovarian stimulation for IVF. One hundred forty-eight patients were selected who underwent two consecutive IVF cycles using same stimulation protocol during 2008 to 2010. Ovarian stimulation was performed with FSH and human menopausal gonadotropin and flexible GnRH antagonist protocol in both cycles. Oocyte maturity was assessed according to presence of germinal vesicle (GV) and the first polar body. Immature oocyte was defined as GV stage or metaphase I oocyte (GV breakdown with no visible polar body) and cultured up to 48 hours. If matured, they were fertilized with ICSI. Percentages of immature oocytes were 30.8% and 32.9% (p=0.466) and IVM rates of immature oocytes were 36.2% and 25.7% (p=0.077), respectively. A significant correlation was noted between percentage of immature oocytes in the two cycles (R=0.178, p=0.03). Women with >40% immaturity in both cycles (n=21) showed lower fertilization rate of in vivo matured oocytes (56.4% vs. 72.0%, p=0.005) and lower pregnancy rate (19.0% vs. 27.1%, p=0.454) after the second cycle when compared with women with <40% immaturity (n=70). In both groups, female age, number of total retrieved oocyte and embryos transferred were similar. In repeated ovarian stimulation cycles for IVF, the immature oocyte tended to be retrieved repetitively in consecutive IVF cycles.
