RESUMEN
[Objective]To investigate the relationship of baseline antimullerian hormone(AMH)and live birth rate of IVF/ICSI and further explore the prognostic effect of AMH on live birth rate.[Methods]All non-polycystic ovary patients who underwent their first embryo transfers in our unit and had basal serum AMH evaluated between 2010 and 2015 were evaluated in this retrospective study. Patients were grouped according to their AMH level,i.e. low AMH group with AMH less than 1.1 ng/mL(n = 485),middle AMH group with AMH between 1.1 ng/mL and 7.0 ng/mL (n = 1 989),and high AMH group with AMH higher than 7.0 ng/mL (n=468). For age subgroup analysis,patients were stratified as follow:group A(age≤29 years),group B(30~34 years),group C(35~39 years)and group D(over 40 years). We compared clinical outcomes between AMH groups in different age groups usingunivariate and multivariate analysis. ROC analysis was utilized to assess predictive value of AMH on live birth rate.[Results](1)In both fresh and frozen embryo transfers,baseline AMH was significantly related to clinical outcomes. The lower AMH was,the lower implantation rate,clinical pregnancy rate,and live birth rate. However,higher miscarriage rate was observed. All difference reached statistically significant.(2)In age subgroup analysis,we demonstrated AMH was related to live birth rate in patients in group A,B, and C,regardless of fresh or frozen embryo transferred. In those over 40 years,AMH was related to live birth rate in frozen cycles (P < 0.05)but not fresh cycles(P = 0.092). The further multivariate analysis confirmed the above results after controlling po?tential confounding variables.(3)The AUC of ROC analysis for AMH predicting live birth rate were 0.647,0.633 for fresh and fro?zen cycles respectively.[Conclusion]Baseline AMH as one of excellent ovarian reserve markers ,was significantly related to live birth rate in fresh or frozen cycles. Baseline AMH was an independent prognostic factor of live birth rate,but its predictive value on live birth rate was of limited clinical value.
