Does male sterilization have an effect on sexual performance? Nowadays, there are many different methods of contraception, so for couples who are sure they don’t want to have any more children, ligation is a once and for all and cost-effective way of contraception! So does male ligation have an effect on sexual performance? Ligation is primarily performed on the male vas deferens, which is a permanent form of birth control. The principle is to cut the vas deferens, which carries sperm from the testicles to the penis, so that the sperm cannot enter the semen and is expelled from the body. The ligation procedure does not adversely affect sexual feelings. For men, the vas deferens and sexual function are like two systems that do not interfere with each other. The ligation of the vas deferens only blocks the tube for sperm to reach from the testicles and mix with the rest of the semen, so the man will still ejaculate and there will be no significant decrease in ejaculate volume because sperm make up only a tiny fraction of the semen and sperm have a certain cycle of production and will wither away if they are not expelled in the body. Vasectomy in men is a reliable form of contraception, with a simple procedure that carries little risk, can be completed in a few minutes, and is easy to revert to unblocking later if you want to get pregnant. Currently, many men in Europe and the United States and other countries use vasectomy for contraception, but not many men in China have undergone vasectomy due to some misconceptions.
