Intrauterine Devices (IUDs) are classified into three main types:

Non-medicated IUDs: e.g., Lippes loop.

Copper-releasing IUDs: e.g., CuT, Cu7, Multiload 375. These release copper ions which suppress sperm motility and the fertilising capacity of sperms.

Hormone-releasing IUDs: e.g., Progestasert, LNG-20. These release hormones that make the uterus unsuitable for implantation and the cervix hostile to the sperms.

Therefore, LNG-20 is a hormone-releasing IUD.
