What method provides the only protection against sexually transmitted infections?

Diaphragm
IUD
Condom
Patch

The correct answer is: Condom

Condoms are designed specifically to provide a barrier that helps prevent the transfer of sexually transmitted infections (STIs) during sexual activity. They are made from materials that effectively block the passage of pathogens, such as viruses and bacteria, thus significantly reducing the risk of infection for both partners. While other methods, like diaphragms or intrauterine devices (IUDs), are effective for pregnancy prevention, they do not offer the same level of protection against STIs. The contraceptive patch also does not prevent the transmission of infections. Therefore, while various contraceptive methods serve to avoid pregnancy, condoms uniquely function to safeguard against STIs, in addition to providing contraceptive benefits.
