Nexplanon/Implanon consists of a single rod made of ethylene vinylacetate copolymer that is 4 cm long and 2 mm in diameter. [31] It is similar to a matchstick in size. The rod contains 68 mg of etonogestrel (sometimes called 3-keto-destrogestrel), a type of progestin. [ 24 ]
A contraceptive implant is an implantable medical device used for the purpose of birth control.The implant may depend on the timed release of hormones to hinder ovulation or sperm development, the ability of copper to act as a natural spermicide within the uterus, or it may work using a non-hormonal, physical blocking mechanism.
It is effective for five years. Nexplanon has replaced the former Implanon and is also a single rod that releases etonogestrel (similar to the body's natural progesterone). The only difference between Implanon and Nexplanon is Nexplanon is radio opaque and can be detected by x-ray. This is needed for cases of implant migration.
Hormonal methods which contain the hormones estrogen and progestin include oral contraceptive pills (there is also a progestin only pill), transdermal patch (OrthoEvra), and intravaginal ring (NuvaRing). Progestin only methods include an injectable form (Depo-Provera), a subdermal implant (Nexplanon), and the intrauterine device (Mirena).
The Pearl Index, also called the Pearl rate, is the most common technique used in clinical trials for reporting the effectiveness of a birth control method. It is a very approximate measure of the number of unintended pregnancies in 100 woman-years of exposure that is simple to calculate, but has a number of methodological deficiencies.
Levonorgestrel-releasing implant, sold under the brand name Jadelle among others, are devices that release levonorgestrel for birth control. [1] It is one of the most effective forms of birth control with a one-year failure rate around 0.05%.
