Of the estimated 6.8 million rapes and physical assaults that occur each year against U.S. women, 2.6 million will result in injury and 792,200 will require health care. The reported incidence of genital injury resulting from sexual assault ranges from 32% on direct visualization to 87% with colposcopy. Physiologic theory suggests that consensual sex is associated with lower rates of genital injury than that of non-consensual sex because of the lack of lubrication that occurs during non-consensual sex.
