Men can still have sex after ligation. Men can still have normal sex after ligation and it will not affect their sex life significantly. Male ligation usually involves ligating both vas deferens to block the transportation of sperm through the vas deferens to the outside of the body, thus preventing the sperm from combining with the egg to achieve contraception. The ligation does not damage the surrounding blood vessels or nerves, so it does not affect normal erectile function, so men can still have normal sex after the ligation. Usually a small amount of sperm may be present in the semen in the early stages of ligation, so contraception is usually needed. The end of contraception can only be considered after several routine semen tests have been performed to make sure that there are no sperm. Male ligation surgery usually takes a minimally invasive approach, after the surgery should pay attention to good cleanliness and hygiene of the wound area, try not to get wet in a short period of time, and also avoid touching the wound with your hands, so as to avoid bacterial growth, which may lead to infection. At the same time, in order to promote the recovery of the wound, try to avoid sexual intercourse within a short period of time. And after the operation, pay attention to maintain sufficient rest, avoid strenuous exercise and heavy physical labor, eat as light as possible, avoid greasy, spicy diet.
