[Penile extensibility and erectile function. Preliminary results].
Extensibility, one of the main biomechanical functions of the penis, has been studied in 422 subjects. Preliminary results showed that a) the flaccid penis was extensible; b) this extensibility was significantly correlated with both age and erectile function. Thus, the more penile extensibility decreased, the more erectile function became impaired. This loss of extensibility is caused by fibrosis of the penis, that mainly affects the corpus cavernosa and, by reducing distensibility, impairs the vascular events involved in erection. Evaluation of the extensibility of the flaccid penis is a new, simple, no-invasive and reproducible clinical test. It contributes to the etiologic diagnosis of impotence by detecting tissular anomalies of the erectile corpora.
