IUCD - Introduction
The intrauterine contraceptive device (IUCD) is a method of family planning that was designed to avoid the general effects of hormonal contraceptives. The device is placed in the cavity of the womb where it exerts its effects. There are two types of contraceptive coils; the copper IUCD and the Mirena which is a special system with a hormone in the place of copper.
