The fluid ejected after a vasectomy is mainly prostate fluid. Since prostate fluid does not contain sperm, the ejected fluid will not lead to pregnancy and can also be called sterilization. Vasectomy only cuts off the vas deferens on both sides of the body, resulting in the sperm produced by the testes not being able to be expelled from the body during sexual intercourse, along with prostate fluid. The resultant semen does not contain sperm and is used as a contraceptive. Although the patient has undergone vasectomy, the secretion function of the testes remains normal, and the sperm can be secreted normally, only that all the sperm secreted normally are stored in the seminal vesicles and cannot be discharged, and the man will still have normal sexual impulses, and it will not affect the normal erection of the penis and sexual life, and the hormone level in the body will not change. According to the related problems, it is recommended to consult a professional urologist.
