Which of the following is a non-medicated intrauterine device(IUD)?

Lippes' Loop

The correct answer is Option (2) – Lippes' Loop.

An effective and popular method of contraception is the use of Intra Uterine Devices (IUDs). These devices are inserted by doctors or expert nurses in the uterus through the 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).

On the other hand, CuT, Cu7, and LNG-20 are examples of IUDs that contain medication or a copper component:

• CuT and Cu7 refer to Copper-T intrauterine devices, which have copper incorporated into the device and these increase phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilising capacity of sperms
• LNG-20 -The hormone releasing IUDs, in addition make the uterus unsuitable for implantation and the cervix hostile to the sperms.
• The Lippes' Loop, unlike the others listed, is a non-medicated IUCD, relying solely on its physical presence within the uterus to prevent pregnancy.
