Vasectomy refer to -

The correct answer is Option (2) → Sterilization procedure in males

Sterilisation is a permanent method of birth control. It blocks the transport of gametes, so conception cannot take place.

(1) Sterilization procedures in females — Incorrect. The procedure in females is called tubectomy. A small part of the fallopian tube is removed or tied.

(2) Sterilization procedure in males — Correct. In vasectomy, a small part of the vas deferens is removed or tied through a small cut on the scrotum. Sperms can then no longer pass out.

(3) Termination of pregnancy — Incorrect. This is medical termination of pregnancy (MTP), which ends a pregnancy that has already begun.

(4) Induced abortion — Incorrect. This is another name for MTP. Vasectomy prevents a pregnancy and does not end one.

NCERT Extract:
Contraceptive Methods – “… Surgical methods, also called sterilisation, are generally advised for the male/female partner as a terminal method to prevent any more pregnancies. Surgical intervention blocks gamete transport and thereby prevent conception. Sterilisation procedure in the male is called ‘vasectomy’ and that in the female, ‘tubectomy’. In vasectomy, a small part of the vas deferens is removed or tied up through a small incision on the scrotum (Figure 3.4a) whereas in tubectomy, a small part of the fallopian tube is removed (Figure 3.4b) or tied up through a small incision in the abdomen or through vagina. These techniques are highly effective but their reversibility is very poor.”
