How effective is the copper IUD (paraguard) to prevent pregnancy?

As good as tubal. Iuds are the most effective method of bc--as effective as sterilization), and the copper iud lasts 10 years. Low rates of side effects, very easy, safe, and effective.
Like sterilization. The CopperIUD is one of the BEST forms of birth control available. Non-hormonal (no effect on fertility/acne/headaches/nausea/wt gain/bloating/blood clots) and VERY safe (except if you have Wilson's dz/Copper allergy). Only risk is a heavier period and complications w/ insertion (RARE). Immediately effective to prevent pregnancy, but DOES NOT protect against STIs. OK for women who haven't had kids.
