Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A), (C) and (D) only
IUDs are of three kinds: non-medicated (Lippes loop), copper releasing and hormone releasing. Copper releasing IUDs give out Cu ions, which suppress sperm motility and the fertilising capacity of sperms.
(A) Cu7 — Correct. It is a copper releasing IUD.
(B) LNG-20 — Incorrect. LNG-20 is a hormone releasing IUD. It makes the uterus unsuitable for implantation and the cervix hostile to sperms.
(C) CuT — Correct. It is a copper releasing IUD.
(D) Multiload 375 — Correct. It is a copper releasing IUD.
NCERT Extract:
Population Stabilisation and Birth Control – “… Another effective and popular method is the use of Intra Uterine Devices (IUDs). These devices are inserted by doctors or expert nurses in the uterus through vagina. These Intra Uterine Devices are presently available as the non-medicated IUDs (e.g., Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and the hormone releasing IUDs (Progestasert, LNG-20) (Figure 3.2).”
