what causes hpv in males

HPV (human papillomavirus) is a sexually transmitted infection that can cause health problems in both men and women. In men, HPV can cause genital warts, which can appear on the penis, testicles, anus, groin, thighs, tongue, and top of the mouth. Some types of HPV associated with genital cancers can lead to cancer of the anus or penis in men, although these cancers are rare, especially in men with a healthy immune system. HPV can also cause oropharyngeal cancer, which occurs in the back of the throat, the base of the tongue, and tonsils. Men who have sex with men are more likely to contract HPV, as are men with weakened immune systems, including those with HIV. HPV spreads by close human contact, including intimate sexual contact, and often there are no symptoms. The best way to prevent HPV is to get vaccinated.
