Male ligation can have sex, but should be avoided during the recovery period, please consult the surgeon in the hospital. The usual treatment for male ligation is to prevent sperm from being discharged by cutting off the vas deferens bilaterally so as to achieve the purpose of contraception, and it will not affect sex life, and you can ejaculate normally, except that there is no sperm present in the ejaculated semen. However, men should avoid sexual intercourse for one month after ligation because there may be residual sperm that can lead to pregnancy. In addition, it is not recommended to have sex for a short period of time after the surgery to avoid bleeding, infection and other complications, and sexual intercourse should be started only after the body recovers from the surgery and there are no abnormal discomfort symptoms. After ligation, men should pay attention to rest, avoid spicy and stimulating food, regular checkups and medication changes, etc. Functional exercises can be carried out appropriately to avoid tissue adhesion.
