Evaluation of clitoral blood flow by color Doppler ultrasonography

The feasibility of reliably measuring clitoral bloodflow using standard col or Doppler ultrasonography was evaluated by two independent assessors in a sample of 40 pre- and post-menopausal women. High positive correlations wit h no significant mean differences between examiners were found for three ma jor standard blood flow measures including maximum velocity, resistance, an d pulsatility indices. With further methodological refinements, ultrasonogr aphic evaluation of clitoral bloodflow will be adaptable for clinical and r esearch use and is likely, to become the standard physiological measure of female sexual arousal.
