Which of the following is a hormone releasing Intra-Uterine Device?

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

Option (4) LNG- 20 — Correct. Hormone-releasing IUDs release a hormone into the uterus. LNG-20 (and Progestasert) are of this kind; they make the uterus unsuitable for implantation and the cervix hostile to sperms.

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).”
