Which IUD is copper-based and hormone-free?

• A. Copper IUD (Paragard)
• B. Mirena IUD
• C. Copper IUD with hormones
• D. Hormonal IUD with copper

Answer: (A)

Copper IUDs are non-hormonal devices that rely on copper to prevent pregnancy. The copper released by the device creates a hostile environment for sperm and disrupts their movement and viability, which reduces the chance of fertilization. Because no hormones are released, it does not affect ovulation or systemic hormone levels. The copper IUD Paragard is the example that fits this description, making it the copper-based and hormone-free option. Hormonal IUDs, like Mirena, release a progestin and work by thickening cervical mucus and thinning the lining of the uterus, not by using copper.
