Which device is a small progesterone-containing implant inserted under the skin and lasts about three years?

• A. Patch
• B. Vaginal ring
• C. Contraceptive implant
• D. Injection

Answer: (C)

Long-acting reversible contraception delivered through an implanted device is the contraceptive implant. It’s a small rod placed under the skin of the upper arm that steadily releases a progestin hormone to prevent pregnancy. Because it’s implanted, there’s no action needed from the user after insertion, and it works for about three years before it needs to be removed or replaced. The other options involve hormones delivered in non-implanted ways—a patch worn on the skin and changed weekly, a vaginal ring placed inside the vagina for a few weeks, or an injection given every few months—so they don’t fit the description of “small implant under the skin lasting about three years.”
