HPV stands for human papillomavirus, and it’s the virus that’s responsible for most cases of cervical cancer. It spreads through skin-to-skin contact with someone who has the virus. To date, about 100 types of HPV viruses have been detected and identified. About a third of these types can affect both male and female genitalia. These types are most commonly spread through vaginal, anal or oral sex. Some types of HPV can cause genital warts. HPV is extremely common, and most men and women become infected with the virus at some point in their lives; however, in most people, the virus does not cause any symptoms or health effects.
