ABSTRACT:
In response to the need of some women for long-acting, effective and safe contraceptive, the scientific community developed non-biodegradable progestational subdermal implants. Contraceptive implants are a form of birth control that contains one to six biodegradable capsules or rods that continuously release progestin into the blood stream for up to five years. The implant system is a set of six matchstick sized, hormone­ containing capsules made of flexible tubing ,works three to five years or until removed. The implants are surgically inserted under the skin in the upper arm(the part of the arm that lies against the side of the rib cage when the arms are at rest) and are one of the most effective birth control methods that require very little maintenance. For women who do not have the time or patience to remember to take a pill on a daily basis, contraceptive implants may be the best option. Contraceptive implants may also be used if a woman smokes, has a risk of cardiovascular disease, has high blood pressure and is breastfeeding. This review focus on introduction, need of contraception, methods of contraception, types, working, maintenance, advantages and disadvantages of implants.
