Contraceptive Coils

Contraceptive Coils

Contraceptive coils (or intrauterine devices - IUDs) are usually used by young women who have had babies. Fitting inside the womb, the IUD is only the length of a matchstick and helps to inhibit pregnancy by preventing sperm from getting through the womb and into the tubes, making the womb lining less able to accept an egg and altering secretions in the cervix thus creating an additional barrier for sperm. Although they do not prevent STIs, they have a 98% effectiveness rate when it comes to birth control. The only notable drawback is that periods may become heavier.
