A consensus on the normal characteristics of corpus cavernosum EMG.

Corpus cavernosum EMG (CC-EMG) has raised much controversy since its introduction. The first workshop on CC-EMG has resulted in acceptance of a standardized technique of recording. Using this technique 110 normal potent volunteers have been examined in different centres. One year later there is an agreement among participants that an analogous recording of CC-EMG during flaccidity in normal subject results in reproducible findings. CC-EMG is characterized by highly reproducible waveforms (potentials) within the individual subject and mostly of comparable shape interindividually. Maximum peak to peak amplitude lies between 75 and > 500 microV and potentials have a mean duration of 12 s.
