Final answer:
The Implanon implant is a hormonal contraceptive, which releases hormones under the skin and has a meager failure rate, making it a highly reliable method of contraception.
Step-by-step explanation:
The Implanon implant is a hormonal contraceptive. This method involves the administration of hormones to prevent ovulation. Hormones can be administered in a variety of ways, including oral pills, injections, skin patches, and through implants like Implanon, which is an implant that releases hormones under the skin. Hormonal contraceptives are generally more effective than barrier methods of contraception, such as condoms and diaphragms. The Implanon implant has a meager failure rate of less than 1 percent, making it one of the most reliable contraceptive methods available.
