Question

Which among the following is hormone releasing IUD?

• A. Cu7
• B. LNG-20
• C. Multiload 375
• D. Lippes loop

Answer 1

The correct option is B LNG-20

All the options given are IUDs, but their modes of action are different.

LNG-20 releases levonorgestrel, a progestin (synthetic hormone similar to progesterone) and makes the uterus unfavourable for implantation, as well as thickens the cervical mucus.

Cu7 and Multiload 375 release copper ions and help in contraception by decreasing sperm motility.

Lippes loop is a double S shaped inert flexible plastic loop and does not contain any hormone. It is a non-medicated IUD.
