Male ligation does not affect sexual function, but it may affect fertility. Male ligation mainly ligates the bilateral vas deferens to block the transportation of sperms, which can prevent sperms from entering the vagina, thus achieving the effect of contraception. Male ligation is a more common form of contraception, but this method does not affect the secretion function of the testes. The testes can also produce androgens normally, so male sexual function is normal. Sexual function is mainly related to androgens, erectile nerves and blood vessels in the penis, and the ligation process does not cause any damage to hormones, nerves or blood vessels. Some men may experience less satisfaction with their sexual function after ligation than before, possibly due to psychological factors. If you have problems with sexual function after ligation, you need to go to a regular hospital in time and seek treatment under the guidance of a doctor.
