Intrauterine Devices (IUDS) (Intrauterine Contraceptive Devices or IUCDs): The devices are made of plastic, metal or a combination of the two and are inserted into the uterus to prevent conception. IUDS are called loops, spirals, rings, bows, shields or Ts depending upon the shape. IUDs are of three types inert, copper releasing and hormone releasing. The inert IUDs are made of polyethylene impregnated with barium sulphate or stainless steel e.g., Lippe's loop. The exact mechanism of inert IUD contraception is not clear.

• There is impairment of sperm ascent.

• There is quick tubal motility resulting in premature migration of fertilised eggs into uterus before it is ready for receiving it.

• Histological and biochemical changes in endometrium which have gametotoxic and spermicidal effect.
