The lack of coitus during IVF does not affect the success rate, and sexual intercourse is not allowed during this period. During IVF, doctors will use gonadotropins and other drugs to promote ovulation, which can help women’s ovaries to produce multiple eggs. During this time, the ovaries are enlarged, so if you have sex, it will affect the hormone secretion of the woman’s body, which will increase the likelihood of ovarian torsion and rupture, and may also reduce the number of eggs produced. Moreover, before the IVF surgery, the eggs need to be retrieved from the vagina. If you have sex, the mucous membrane of the vagina will be affected, which will prevent the retrieval of the eggs from taking place normally. Therefore, you should not have intercourse during the IVF period, and if you experience any discomfort during the IVF procedure, you should go to the hospital in time for treatment.
