After ligation, the fluid excreted does not contain sperm. The main purpose of male sterilization is to tie off the vas deferens, preventing the sperm formed in the testicles from being excreted through the vas deferens. Moreover, during ejaculation during sex after sterilization, some fluid secreted by the prostate gland and some fluid produced by the para-urethral glands will be excreted like water with the ejaculatory action. After ligation, there will still be sexual pleasure during intercourse and some fluid will be secreted, but it will not lead to pregnancy because the sperms have been blocked and the excreted fluid does not contain sperms. Men should avoid sexual intercourse for two weeks after ligation surgery, ensure rest, and avoid strenuous exercise. Contraception should be continued for 3 months after the ligation surgery.
