With the extensive use of highly efficient embryo cryopreservation technology, cumulative live birth rate (CLBR) encompassing live birth outcomes in the fresh and subsequent frozen embryo transfer (FET) following a single ovarian stimulation cycle is progressively regarded as a significant indicator for assessing the success of ART but so far, no study has directly explored the relationship of CLBR and baseline AMH level in PCOS patients. The gene discussed is AMH; the disease is polycystic ovary syndrome.
