Hebei reader Zhang Guang asked: My wife and I have been married for three years and just had a baby. We used oral contraceptives for contraception before, but because my wife was breastfeeding, I was worried that the contraceptives would harm the child, so I wanted to have a ligation. I heard that Zaza’s operation cut off the vas deferens, and I was worried that it would affect my sexual ability and future sex appeal. Is such a worry reasonable?
Zhang Zhichao, deputy director of the Andrology Center of Peking University First Hospital, replied: The zha operation mainly targets the male vas deferens, which is a permanent contraceptive method. The principle is to cut off the vas deferens, which transports sperm from the testicle to the penis, so that the sperm cannot enter the semen and exit the body. Vasectomy does not adversely affect sex appeal. For men, the vas deferens and sexual function are like two systems that do not interfere with each other. A vasectomy only blocks the ducts that lead sperm from the testicles to mix with other semen, so the man still ejaculates without reducing the apparent volume of ejaculate. Sperm only account for a very small part of semen, and the production of sperm has a certain cycle. If it is not excreted in the body, it will wither.
Male vasectomy is a reliable method of contraception. The operation is simple, the risk is small, and it can be completed in a few minutes. It is also very convenient to resume dredging after pregnancy in the future. At present, many men in Europe, America and other countries use vasectomy for contraception, but due to some misunderstandings in China, not many men receive vasectomy.
