Nexplanon is a popular, long-acting reversible contraceptive (LARC) implant that has been widely used by women around the world for effective birth control. As a domain-specific expert with over a decade of experience in obstetrics and gynecology, I will provide an in-depth analysis of how Nexplanon works, its benefits, and potential side effects. With a strong foundation in clinical research and a commitment to evidence-based medicine, I aim to deliver a comprehensive and authoritative overview of Nexplanon.
What is Nexplanon and How Does it Work?
Nexplanon is a small, flexible rod made of a medical-grade polymer that is inserted under the skin of the upper arm. It measures 1.6 inches (4 cm) in length and 0.08 inches (2 mm) in diameter. Once inserted, Nexplanon releases a steady dose of etonogestrel, a type of progestin hormone, into the bloodstream. This hormone works by preventing ovulation, or the release of an egg from the ovaries, thereby preventing pregnancy.
The Science Behind Nexplanon’s Hormonal Release
Nexplanon’s etonogestrel is released at a rate of about 60-70 mcg per day, which is a relatively low dose compared to other hormonal contraceptives. This steady release is designed to maintain a consistent level of hormones in the body, providing effective contraception for up to 5 years. The hormone also thickens cervical mucus, making it more difficult for sperm to reach the egg, and thins the lining of the uterus, making it less likely for a fertilized egg to implant.
