Step-by-step explanation:
Implantable Progestin Etonogestrel (Implanon), also known as the Implanon implant, is a form of birth control that is inserted under the skin of the upper arm. The implant releases a progestin hormone, which prevents ovulation and thickens cervical mucus to prevent sperm from reaching an egg. While the Implanon implant can be an effective method of contraception, there are potential risks and complications associated with its use. These include weight loss, skin irritation at the implant site, and an increased risk of blood clots. However, improved bone density is not a reported risk or possible complication of the Implanon implant.
