Vasectomy and Tubectomy: Sterilization — NEET Biology
✅ Asked in NEET 2021Surgical 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 whereas in tubectomy, a small part of the fallopian tube is removed or tied up through a small incision in the abdomen or through vagina. These techniques are highly effective but their reversibility is very poor.
NTA tests whether students understand these permanent contraceptive surgical methods and how they prevent conception. Vasectomy blocks vas deferens in males; tubectomy blocks fallopian tubes in females. Students often confuse these procedures with temporary methods or mix up which surgery applies to which sex. The critical point to remember: both work by blocking gamete transport, making conception impossible, but have poor reversibility—this irreversibility distinguishes them from other contraceptives. Focus on the mechanism (blocking gamete/sperm passage) rather than anatomical details, as NTA frequently asks mechanism-based questions on sterilization procedures.
