Implanon is a subdermal contraceptive implant that primarily contains progestin, specifically etonogestrel, which is a derivative of progesterone. Progestin plays a crucial role in providing long-term contraception as it suppresses ovulation, thickens cervical mucus, and thins the endometrial lining, thereby preventing pregnancy.

While levonorgestrel and progesterone are related concepts—levonorgestrel being another form of progestin and progesterone being a natural hormone—Implanon’s formulation is specifically designed to utilize progestin's contraceptive effects without the inclusion of estrogen. This makes it a suitable option for various populations, especially those who cannot take estrogen due to medical reasons or personal preferences.

Understanding the mechanism and function of the components within contraceptive methods is essential for ensuring appropriate patient education and guidance in selecting the right contraceptive method based on individual health needs.
