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).
