Highly effective and relatively hidden, the small, matchstick-sized implant is placed just below the skin of your upper arm where it continuously releases the hormone progestin in small doses from a reservoir into your blood stream. The hormone keeps your ovaries from releasing eggs but also thickens your cervical mucus making it hard for sperm to move around in the womb and fertilize an egg.
After administering local anesthesia, a well-trained healthcare provider will numb a small area of your inner upper arm and insert the implant just underneath the surface with a special needle. The implant releases small amounts of hormones into your blood over the course of up to 3 or 5 years, depending on the type. It is suitable for women who want highly effective and long-acting but reversible contraception and wish to avoid a daily, weekly or monthly regimen. It can be removed at any time with minor surgery by a well-trained healthcare provider. Once the implant is removed, the contraceptive effect wears off quickly and you can become pregnant as rapidly as women who have used no contraceptive at all.
