A 10-year follow‐up on the practice of luteal phase support using worldwide web‐based surveys
Abstract Background It has been demonstrated that luteal phase support (LPS) is crucial in filling the gap between the disappearance of exogenously administered hCG for ovulation triggering and the initiation of secretion of endogenous hCG from the implanting conceptus. LPS has a pivotal role of in...
