The Hormone Releasing Intra Uterine Device (IUD) is a type of IUD that releases hormones to prevent pregnancy. The correct answer is:
(2) LNG-20: The LNG-20 is a hormone-releasing intrauterine device that releases Levonorgestrel (LNG), a synthetic progestin, into the uterus to prevent pregnancy. It is designed for long-term contraception.
Here’s a brief explanation of the other options:
(1) Lippes loop: This is a non-hormonal IUD that works through a mechanical mechanism and does not release hormones.
(3) Multiload 375: This is another non-hormonal IUD that uses copper as its active ingredient for contraception.
(4) Cu 7: This is also a copper-based IUD and does not release hormones.
Thus, the correct answer is (2) LNG-20.
LNG-20 is a hormone-releasing IUD that releases levonorgestrel, a type of progestogen, which helps in birth control by thickening cervical mucus and preventing ovulation.
