Which of the following options is considered a nonhormonal contraception?

• A. Copper IUD
• B. LNG-releasing intrauterine system
• C. Etonogestrel implant
• D. Combined oral contraceptive pill

Answer: (A)

Nonhormonal contraception refers to methods that do not introduce hormones into the body. The copper IUD achieves this because it remains in the uterus and uses copper to disrupt sperm function and create a hostile uterine environment, preventing fertilization without releasing any hormones. In contrast, the LNG-releasing intrauterine system and the etonogestrel implant release progestin (hormones) and work by altering cervical mucus, the endometrium, and sometimes ovulation. The combined oral contraceptive pill contains estrogen and progestin, a clearly hormonal approach. Therefore, the copper IUD is the nonhormonal option.
