Human papillomavirus (HPV) infection is usually transmitted sexually, though rare cases have been reported in virgins. [93] Condom use may not prevent transmission. [93, 94] A study in a mouse model by Roberts et al found that a widely used vaginal spermicide, nonoxynol-9, greatly increased susceptibility to HPV infection, whereas carrageenan, a polysaccharide present in some vaginal lubricants, prevented infection.
