The earliest day of egg retrieval after IVF depends on the woman’s own estrogen production and follicle development, which needs to be analyzed on a case-by-case basis. If a woman has a high level of estrogen production, her follicles may develop faster, usually about a week after ovulation, and it is more appropriate to retrieve eggs at that time. However, for some women with low estrogen secretion and weak body, the time for egg retrieval after ovulation will be extended, maybe 10-15 days or longer. Before egg retrieval, you should get enough sleep and feel comfortable, avoid mood swings and have a balanced diet. It is also important to keep the vulva clean.
