The contraceptive implant is long-acting reversible contraception (LARC). Like other progestin-only contraceptives, it works through the regulation of progestin levels: inhibiting ovulation, thinning the endometrium, and thickening the cervical mucus. With an insertion time of < 1 minute, the implantable device is the most effective form of birth control.

Worldwide, > 100 million unplanned pregnancies occur each year, making accessibility of contraception a public health priority. Short-acting contraceptive methods, such as oral contraceptives and vaginal rings, are dependent upon user adherence. Conversely, LARCs, intrauterine devices (IUDs), and subdermal contraceptive implants provide continuous pregnancy prevention without ongoing effort from the user. Thus, they are an excellent method of preventing unplanned pregnancies in persons desiring future pregnancy.
