Which procedure involves cutting and sealing the vas deferens?

The procedure that involves cutting and sealing the vas deferens is a vasectomy. This surgical intervention is a form of male sterilization aimed at preventing sperm from mixing with semen during ejaculation. During a vasectomy, the vas deferens, which are tubes responsible for transporting sperm from the testicles to the urethra, are either cut or blocked. This effectively prevents sperm from exiting the male reproductive system, thereby achieving permanent contraception.

In contrast, tubal ligation refers to a procedure for females where the fallopian tubes are blocked or severed to prevent eggs from reaching the uterus. Hysterectomy involves the surgical removal of the uterus, which is not relevant to male sterilization. Endometrial ablation is a procedure aimed at destroying the lining of the uterus to treat various uterine conditions, but it does not involve the vas deferens either. Therefore, a vasectomy specifically addresses the male reproductive system and ensures contraception through the alteration of the vas deferens.
