Vulvar trauma is more common in prepubertal children due to small labial fat pads and more physical activity. Adults are more protected. Though some injuries are serious, most are accidental minor blunt traumas. The most common type of injury is a straddle injury, which can be incurred through normal activities like bicycle riding. Due to the vascularity of the vulva, it may form a large hematoma when injured. The vulva can also be injured through sexual assault. Vulvar trauma can occur concurrently with vaginal trauma, especially if a sharp object is involved
Vaginal trauma can occur when something is inserted into the vagina, for example, a sharp object, causing penetrating trauma
Penile trauma can take several forms. Abrasions can be caused by a zipper injury, and fractures can be caused by sexual activity.
