I.U.C.D. (Intra Uterine Contraceptive Devices)

Posted by e-Medical PPT Wednesday, March 7, 2012
The intrauterine device (IUD) is a form of birth control; it is an object placed in the uterus to prevent pregnancy.There are two types of intrauterine contraceptive available: the copper Paragard and the hormonal Mirena. Copper IUDs work by impairing the mobility of sperm and preventing them from joining with an egg. Additionally, the foreign body irritates the lining and wall of the uterus making it hard for an embryo to implant.Most non-hormonal IUDs have a plastic T-shaped frame that is wound around with pure electrolytic copper wire and/or has copper collars.The arms of the frame hold the IUD in place near the top of the uterus.
The hormal I.U.D. (Mirena) does not increase bleeding as copper-containing IUDs do. Rather, they reduce menstrual bleeding or prevent menstruation altogether, and can be used as a treatment for menorrhagia.Although use of the Mirena results in much lower systemic progestogen levels than other very-low-dose progestogen-only hormonal contraceptives, they might possibly have some of the same side effects.
