The correct answer is (B) : LNG-20.
The correct answer is: (B) LNG-20.
An example of a hormone-releasing intrauterine device (IUD) is LNG-20. LNG-20 is a type of intrauterine system that releases the hormone levonorgestrel (LNG) into the uterus. This hormone is a synthetic form of progesterone, which works to prevent pregnancy by thickening cervical mucus, thinning the endometrial lining, and inhibiting ovulation.
The LNG-20 IUD is a long-acting, reversible contraceptive method that can provide protection against pregnancy for up to five years. It is highly effective and often preferred by women who want a hormone-based contraceptive option without the need for daily pills. Hormonal IUDs, like LNG-20, have a lower risk of side effects compared to other hormonal methods like the birth control pill.
Thus, LNG-20 is a hormone-releasing IUD used for contraception.
