After undergoing surgery for an ovarian teratoma, generally, sexual intercourse can resume about a month later. However, the specific timing depends on the patient's recovery. Some women who are physically stronger may recover faster and can have sexual intercourse around a month post-surgery. However, if a female patient is relatively weak, recovery might be slower, and it is advised to wait until full recovery before engaging in sexual intercourse. It is essential to take contraceptive measures during intercourse to avoid pregnancy. After surgery, it is recommended to wait until at least three months post-surgery, when the body has recovered well, before attempting pregnancy. Regular prenatal check-ups should be done after conceiving.
