Which one of the following contraceptives is an example of non medicated intra uterine device?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Lippes loop
Intra uterine devices (IUDs) are devices placed in the uterus through the vagina to prevent pregnancy. They are of three kinds. Non-medicated IUDs release nothing. Copper releasing IUDs release copper ions. Hormone releasing IUDs release a hormone.
(1) Multiload 375 — Incorrect. It is a copper releasing IUD, like CuT and Cu7. The copper ions lower the movement and fertilising power of sperms.
(2) LNG-20 — Incorrect. It is a hormone releasing IUD. It makes the uterus unsuitable for implantation and the cervix hostile to sperms.
(3) Progestasert — Incorrect. It is also a hormone releasing IUD.
(4) Lippes loop — Correct. Lippes loop is the example of a non-medicated IUD. It does not release copper or any hormone.
