Normally, if egg retrieval is performed after ovulation promotion, it takes at least about three months for the ovaries to recover. Generally, ovulation is mostly performed with clomiphene, which may affect the function of the ovaries, so it takes at least three months to recover. If fresh embryos are to be transferred in the future, it is necessary to remove the mature eggs and combine them with suitable sperm in time to form a fertilized egg for transfer into the uterine cavity. At this time, the ovaries have not fully recovered and cannot produce enough progesterone to maintain endometrial metaplasia, so exogenous drugs are needed to support the treatment. However, patients should never stop the medication on their own because the ovaries have not recovered their function and cannot supply it on their own. In addition, patients should pay more attention to rest during the period after egg retrieval, avoid straining and irregular work and rest, and refrain from eating spicy and stimulating foods.
