title: A new device for diagnostic screening of nocturnal penile tumescence.
abstract: An erectometer for the measurement of sleep erections is described. Comparative studies using simultaneously strain gauges and the new device indicate that it possesses a significant potential for valid measurement of the circumferential increase that may occur during sleep. Because of its reliability, simplicity and low cost the erectometer is proposed as a screening procedure or as a diagnostic alternative when sleep laboratory facilities are not feasible.
