What is a key characteristic of condoms in terms of sexual health?

Condoms are a significant component of sexual health due to their dual protective abilities. They are designed to prevent both sexually transmitted infections (STIs) and unwanted pregnancies, making them a vital tool for safe sexual practices.

When used consistently and correctly, condoms act as a barrier preventing the exchange of bodily fluids that can transmit STIs, including HIV, gonorrhea, and chlamydia. At the same time, they create a physical barrier that prevents sperm from fertilizing an egg, thereby reducing the risk of pregnancy. This dual protection is why many health organizations recommend condoms as an effective method of contraception and protection against STIs.

In contrast, certain other characteristics, such as requiring a prescription or only preventing pregnancy, do not accurately reflect the comprehensive role condoms play in sexual health. Additionally, while it is true that effectiveness can diminish with improper use, this aspect does not pertain to the fundamental characteristics of condoms themselves. Thus, the assertion that condoms protect against both STIs and pregnancy encapsulates their primary function in promoting safer sexual practices.
