Copper IUD
/KOP-er I-U-D/
An intrauterine device that can be used as emergency contraception when inserted within 5 days of unprotected sex, and then provides ongoing contraception.
Detailed Explanation
The copper IUD (intrauterine device) is the most effective form of emergency contraception, preventing more than 99% of pregnancies when inserted within 5 days of unprotected sex. It works by creating an environment toxic to sperm and eggs. Unlike EC pills, it can be inserted up to 5 days after ovulation (not just after unprotected sex), giving a potentially longer window. It then continues working as regular contraception for up to 10-12 years.
