Th investigation of organic impotence

A proportion of impotent men may have one or more underlying organic causes for their impotence and might benefit from the implantation of a silastic penile prosthesis. In order to identify those men with organic impotence we have investigated 30 impotent men. The methods used have included the assessment of penile arterial perfusion by techniques involving a Doppler probe, nocturnal penile tumescence studies, cystometry and cavernosography. Despite the limitations of these various techniques their combined use may help in the recognition of organic impotence and thus facilitate its treatment.
