No: The copper IUD does not prevent std infections and can actually increase the chances. Only Mirena (levonorgestrel) is approved for decreasing the risk of std.

IUD: No. The main protection against std is condom and monogamy. As a matter of fact if exposed to a STI the iud may promote or complicate the infection and may need to be removed.

I agree, the answer is a big N-O!! Cooper IUDs should never be used in women who are potentially non-monogamous.

NO!: Iuds offer no protection against sexually transmitted diseases. They are very effective at preventing pregnancy, however. The most effective method of preventing the spread of STDs is using condoms every single time.

No.: 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
