The hormonal contraceptive method is:

The correct answer is Option (4) → LNG-20

Intra uterine devices (IUDs) are placed in the uterus to prevent pregnancy. They are of three kinds: non-medicated IUDs (Lippes loop), copper releasing IUDs (CuT, Cu7, Multiload 375) and hormone releasing IUDs (Progestasert, LNG-20). A hormonal method works through a hormone such as a progestogen.

(1) CuT — Incorrect. CuT is a copper releasing IUD. The copper ions reduce sperm motility and the fertilising capacity of sperms. It releases no hormone.

(2) Cu7 — Incorrect. Cu7 is also a copper releasing IUD, not a hormonal one.

(3) Saheli 375 — Incorrect. Saheli is an oral contraceptive pill for females. It contains a non-steroidal preparation and is taken once a week, so it is not a hormone like the progestogens.

(4) LNG-20 — Correct. LNG-20 is a hormone releasing IUD. It makes the uterus unsuitable for implantation and the cervix hostile to the sperms.
