Pregnancy Rate Is High When the Length of the Luteal Phase During the In Vitro Fertilization Hormone Replacement Cycle Is 144 Hours or More Before Embryo Transfer
This study clarified two aspects. First, the pregnancy rate in the 144-h group was significantly higher than that in the 132-h group in the analysis of all embryos. Second, the window of implantation may be more important for poor-quality embryos. This study showed that the oral administration of dydrogesterone requires a window of implantation of at least 144 hours.
