Norplant and Nuvaring are examples of which type of birth control method?

• A. Barrier methods
• B. Hormonal birth control methods
• C. Surgical sterilization
• D. Copper IUD

Answer: (B)

These are hormonal birth control methods. They work by delivering hormones that prevent ovulation and alter the cervical environment to reduce the chance of fertilization. Norplant is a subdermal implant that continuously releases a progestin over several years, blocking ovulation. Nuvaring is a vaginal ring that releases estrogen and progestin for a few weeks each cycle, also preventing ovulation and thickening cervical mucus. They’re not barrier methods (which physically block sperm), not surgical sterilization (permanent), and not the copper IUD (a non-hormonal device that acts mainly through local effects in the uterus).
