A new device for diagnostic screening of nocturnal penile tumescence.
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.
