IUDs (Intra Uterine Devices) are inserted by doctors or expert nurses in the uterus through the vagina (making Statement I false and II true). They are available as non-medicated, copper releasing, and hormone releasing types (Statement III true). They are one of the most widely accepted methods of contraception in India (Statement IV true). Statement V is incorrect because the full form is Intra Uterine Devices, not Inter.
