PURPOSE: Special attention has been focused on the contribution of the ischiocavernosus muscles to intracorporeal pressure during erection. MATERIALS AND METHODS: Length of the ischiocavernosus muscles and corpora cavernosa was studied in 30 cadavers. RESULTS: A biomechanical model for calculating interference of the ischiocavernosus muscles in rigidity during the initial phase of penile erection is proposed. CONCLUSIONS: We found that, among other things, intracorporeal pressure can be influenced by the ischiocavernosus muscles during erection.
