Which method is a hormonal long-acting reversible contraception?

• A. Copper IUD
• B. LNG IUS
• C. Condom
• D. Diaphragm

Answer: (B)

Hormonal long-acting reversible contraception uses a method that releases a progestin over an extended period to prevent pregnancy. The LNG IUS fits this because it continuously releases levonorgestrel directly into the uterus, providing contraception for several years. The hormone works mainly locally: it thickens cervical mucus to block sperm, thin the lining of the uterus, and can suppress ovulation in some cycles. Because the hormone is delivered via an intrauterine device, systemic exposure is lower than with pills, yet the effect is long-lasting and reversible once the device is removed.

In contrast, a copper IUD is non-hormonal; it prevents pregnancy through copper’s local effects in the uterus. Condoms and diaphragms are barrier methods, not hormonal or long-acting.
