Serum AMH concentrations were compared between responders and non-responders. The receiver-operating characteristic（ROC）curve was used to evaluate the prognostic value of circulating AMH.Results hM G responders had a significantly lower serum AMH concentration compared with non-responders（8.43±2.18 μg/L vs 11.05±2.85 μg/L, P〈0.001）. In multivariate Logistic regression analysis, AMH was an independent predictor of ovulation induction by hM G in PCOS patients. ROC curve analysis showed AMH was a useful predictor of ovulation induction by hM G in PCOS patients, having 91.7% specificity and 66.7% sensitivity when the threshold AMH concentration was 10.12 μg/L.Conclusion Serum AMH can be used as an effective parameter to predict ovarian response to hM G treatment in PCOS patients.展开更多

Methods In the retrospective study, 842 patients undergoing IVF were collected and classified into two groups： hMG in combination with CC in mid-to-late follicular phase （group A, n=319） and short protocol of GnRHa-hMG （group B, n=523）. The main outcome measures were ovarian responses in stimulation cycles and pregnancy outcomes in subsequent frozen-thawed embryo transfer （FET） cycles. Results In group A, the serum LH concentration on day 8 -10 was similar with that on the day of hCG administration （2.43 ± 1.92 IU vs 2.51 ±2.05 IU）. The number of mature follicles and oocytes retrieved was significantly lower in group A than in group B while the fertilization rate and the cleavage rate were comparable. The clinical pregnancy rate （47. 79% vs 48.04%）, the implantation rate （32.49% vs 33.11%） and the cumulative pregnancy rate （58.09% vs 60.22%） were respectively similar in group A and group B. Conclusion hMG in combination with CC in mid-to-late follicular phase results in the same pregnancy outcome as short protocol. The novel protocol may take the advantage of eliminating the occurrehce of a premature endogenous LH Surge.展开更多
