A contraceptive implant is a type of birth control. It is a small flexible tube measuring about 40mm in length which is inserted under the skin by a health care professional(typically the upper arm). The implant is among the most effective birth control methods. After it is inserted it prevents pregnancy by releasing hormones that prevent ovaries from releasing eggs and by thickening cervical mucous. The implant can prevent pregnancy for up to three years. Though it protects against pregnancy, it does not protect against STIs. The costs for implantation range. Brands include:
- Norplant and Jadelle (Norplant II)
- Sino-implant (II) marketed as Zarin, Femplant and Trust
