It is best not to have intercourse for 20 days after egg retrieval, and it is recommended that you have your period after egg retrieval or have sex after a month. Although egg retrieval is a minor surgery, most people will experience abdominal pain, bloating and other uncomfortable symptoms. The process of egg retrieval will also cause some damage to the ovaries, which need to recover and stop bleeding, and it is not recommended to have intercourse too early. Some women may undergo embryo transfer within a short period of time after egg retrieval, and after the transfer, they have to pay attention to observe the development of the embryo, and premature coitus may affect the embryo implantation. Therefore, if embryo transfer has been carried out after egg retrieval, it is not recommended to have sexual intercourse in the early stage of pregnancy, so as not to cause transplantation failure, induced preeclampsia and habitual abortion. Ovulation stimulation treatment will cause the ovaries to be stimulated and lead to enlargement, and premature intercourse may lead to rupture of the ovaries or ovarian torsion, which may lead to the occurrence of acute abdomen or hemorrhage. In addition, it takes some time for the ovaries to function and stop bleeding after egg retrieval Therefore, it is usually recommended to wait for a woman to have her period or for a month before having sex after egg retrieval without embryo transfer. Before intercourse, it is recommended to go to the hospital to review the ultrasound, if the size of the ovary has returned to normal and there are no other symptoms, then you can have intercourse appropriately. In addition, women should also be careful not to exercise strenuously after egg retrieval, and if there is abdominal pain or acute abdomen, etc., they must go to the gynecology clinic in time.
