Magnetic resonance imaging of male and female genitals during coitus and female sexual arousal
BMJ 1999;319:1596-1600 ( 18 December )
"Their most remarkable observations regarding sexual arousal in the woman were the backwards and upwards movements of the anterior vaginal wall (vaginal tenting) and a 50-100% greater volume of the uterus. This increase disappeared 10-20 minutes after orgasm. When sexual excitement without orgasm occurred, the volume returned to normal in 30-60 minutes. Masters and Johnson presumed that the greater volume of the uterus was due to engorgement with blood. However, they qualified their presumption: "In view of the artificial nature of the equipment, legitimate issue may be raised with the integrity of observed reaction patterns."
