Mention the surgical methods of contraception in: 1. Human males 2. Human females.
Topic: Surgical methods of contraception
Answer
- HUMAN MALES — VASECTOMY: the VAS DEFERENS (sperm duct) is cut and tied, so sperms cannot pass into the semen.
- HUMAN FEMALES — TUBECTOMY (tubal ligation): the FALLOPIAN TUBES are cut and tied, so the ovum cannot travel down and sperms cannot reach it.
Name the method AND the structure cut — that is what distinguishes a full answer from a bare name.
Each name contains its structure: VAS-ectomy cuts the VAS deferens, TUBE-ctomy cuts the fallopian TUBES. Reading the word prevents confusion.
WHAT THESE OPERATIONS DO NOT DO, a common follow-up question: a vasectomy does not stop the production of testosterone, and a tubectomy does not stop ovulation, menstruation or hormone secretion. Only the passage of the gametes is blocked.
Both are SURGICAL and regarded as PERMANENT, which distinguishes them from temporary methods — the condom, diaphragm, copper T and oral pills.
