Does an IUD provide protection against STIs?

An intrauterine device (IUD) is primarily designed to prevent pregnancy and is not effective in providing protection against sexually transmitted infections (STIs). The primary function of an IUD is to create an environment in the uterus that is unfavorable for sperm and implantation, which aids in contraception. However, the protective measures against STIs come from barrier methods, such as condoms, which physically block the transmission of infections during sexual activity.

While some IUDs, like the hormonal types, can offer certain non-contraceptive health benefits, such as regulating menstrual cycles or reducing menstrual pain, they do not have any antiviral or antibacterial properties that would provide protection against STIs. Understanding this distinction is crucial for individuals who are considering the use of IUDs as their only form of sexual health protection.
