Men are able to excrete semen after sterilization, which is composed mainly of prostate fluid and does not contain sperm. The main purpose of male ligation surgery is to cut off the vas deferens, which transports sperm, so that the semen can’t be discharged out of the body, thus achieving the effect of sterilization. After the ligation surgery, there will still be fluid discharged out of the body, but it does not include sperm, and the fluid discharged is usually dominated by the fluid secreted by the prostate gland, which does not have the effect of fertilization. Men should have preoperative counseling before ligation surgery to eliminate concerns. After surgery, some patients may experience complications such as scrotal enlargement and skin bleeding, and patients should seek medical attention in a timely manner. Intercourse should be prohibited for 2 weeks after the operation, and contraception should be continued for 3 months because sperm may remain at the distal end of the amputated vas deferens. Men who experience discomfort after ligation should seek medical attention.
