Nocturnal penile tumescence and rigidity monitor having detachable loops

A penile rigidity and tumescence monitor and apparatus including a transducer apparatus (20) for providing output signals indicative of penile rigidity and tumescence throughout a penile tumescent event. A control apparatus (22) being operatively interconnected to the transducer apparatus (20) for providing control thereover. A control apparatus (22) also provides for acquisition and storage of penile rigidity and tumescence data represented by the output signals received from the transducer apparatus (20). The transducer apparatus (20) includes readily detachable loop-like portions (38) enabling replacement of the loop-like portions (38).
