The technique of sterilizing a male by blocking the vas deferens is known as:
Vasectomy
∙ Vasectomy is a surgical procedure for male sterilisation and/or permanent contraception. During the procedure, the male vas deferens are severed and then tied/sealed in a manner so as to prevent sperms from entering into the seminal stream (ejaculate) and thereby preventing fertilisation.
∙ Tubectomy is a similar process in females where the fallopian tube is sealed.
∙ Hysterectomy is the removal of uterus which is carried out only is severe disease conditions.
∙ Mastectomy is the medical term for the surgical removal of one or both breasts, partially or completely.
