IUCD
What?
The intrauterine
device (IUD) is a form of birth control; it is an
object placed in the uterus to prevent pregnancy.[1]
Types?
Among modern IUDs, the two types available are copper-containing devices, and a hormone-containing
device that releases a progestogen.
Currently, there are over 10 different kinds of
copper IUD available in different parts of the world, and there is one hormonal
device, called Mirena.
Copper IUCD
· 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.[5]
Hormonal IUCD
· The hormonal I.U.D. (brand name 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 (heavy periods).
· 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.
