Human papillomavirus (HPV) is a widespread sexually transmitted infection. In both men and women, HPV infection can result in a spectrum of genitourinary manifestations ranging from genital warts to cancer. Cervical cancer is nearly always associated with high-risk HPV infection. For men, penile cancer can develop following or independently of HPV infection. Basaloid and warty subtypes of penile squamous cell carcinoma are most frequently associated with HPV infection. Further research into the molecular alterations caused by HPV infection may provide prognostic markers and future treatment targets. Until an effective treatment for HPV infection is developed, prevention will remain the focus of disease control. For women, vaccination is increasingly utilized to prevent HPV infection and subsequent cervical cancer development. New recommendations for routine male vaccination may further reduce cancers for both men and women.
