Male<unk> s being stress tested by adding water, as part of a museum exhibit.<unk>  is how effective<unk> s are at preventing STDs and pregnancy. Correctly using male<unk> s and other barriers like female<unk> s and dental dams, every time, can reduce (though not eliminate) the risk of sexually transmitted infections (STIs), including human immunodeficiency virus (HIV) and viral hepatitis. They can also provide protection against other diseases that may be transmitted through sex like Zika and Ebola. Using male or female<unk> s correctly, every time, can also help prevent pregnancy. Consistent and correct use of male latex<unk> s can reduce (though not eliminate) the risk of STD transmission and pregnancy. To achieve the maximum protective effect,<unk> s must be used both consistently and correctly. Inconsistent use can lead to STD acquisition or pregnancy because transmission or conception can occur with a single act of intercourse. Similarly, if<unk> s are not used correctly, the protective effect may be diminished even when they are used consistently. The most reliable ways to avoid transmission of sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV), are to abstain from sexual activity or to be in a long-term mutually monogamous relationship with an uninfected partner. However, many infected persons may be unaware of their infections because STDs are often asymptomatic or unrecognized.
