The implant is a prescription birth control method that offers prolonged protection against pregnancy. The implant contains a single hormone - a progestin - which stops ovulation and/or changes cervical mucus thereby preventing pregnancy.

What does it look like?
The implant consists of one or six match-sized plastic rods which your family physician or gynecologist inserts under skin of your upper arm, using a local anesthetic. The rods release a constant dose of a hormone, progestin, thereby protecting against pregnancy. A modern alternative consists of only one rod and is inserted by means of a specially designed disposable applicator.

How effective are they?
The implant is considered to be most effective form of contraception available. Once in place it lasts for a period of three to five years. During that time it provides 99.8% or even more protection against unintended pregnancy.

Are there any other benefits besides contraception?
Yes. The implant offers additional health benefits or "non-contraceptive benefits" which are same for all progestin-only contraceptive methods.
