Human papilloma virus: to what degree does this sexually transmitted infection affect male fertility?
Human papilloma virus (HPV) is the most common sexually transmitted infection in men and women in the United States; approximately 79 million Americans are estimated to have an active infection (1). Some infections may be asymptomatic and clear without consequence. Other HPV-related infections may have minimal consequences, such as benign genital warts. However, strong evidence suggests that some subtypes of HPV are a primary driving etiologic factor for the development of cervical, oral, penile, and anal cancers.
