In this retrospective study, patients with positive h CG(day 12 after transfer) were included to examine the h CG levels and their predictive value for pregnancy outcomes following 214 fresh and 1513 vitrified-warmed single-blastocyst transfer cycles. For patients who got clinical pregnancy, the mean initial h CG value was significantly higher after frozen cycles than fresh cycles, and the similar result was demonstrated for patients with live births(LB). The difference in h CG value existed even after adjusting for the potential covariates. The area under curves(AUC) and threshold values calculated by receiver operator characteristic curves were 0.944 and 213.05 m IU/m L for clinical pregnancy after fresh ET, 0.894 and 399.50 m IU/m L for clinical pregnancy after frozen ET, 0.812 and 222.86 m IU/m L for LB after fresh ET, and 0.808 and 410.80 m IU/mL for LB after frozen ET with acceptable sensitivity and specificity, respectively. In conclusion, single frozen blastocyst transfer leads to higher initial h CG values than single fresh blastocyst transfer, and the initial h CG level is a reliable predictive factor for predicting IVF outcomes.展开更多
