Laser Doppler Imaging of Genital Blood Flow: A Direct Measure of Female Sexual Arousal

LDI appears to be able to differentiate blood flow during erotic and nonerotic conditions. In addition, physiological sexual arousal was significantly predicted by women's reported subjective sexual arousal. These findings suggest that LDI is a useful instrument for measuring female sexual arousal, and that women may be more aware of their level of physiological arousal than previously assumed.
