Erectile dysfunction (ED) is an increasingly prevalent medical problem, affecting up to 50% of men aged between 40 and 70-y-old. Many cases are vasculogenic and some of these stem from the inability of the penis to store blood during erection due to leak into the venous system, termed corporo-venocclusive dysfunction (CVOD). The area of leakage during erection could be the most direct measure of erectile function but has not been investigated before. We have developed a simple mathematical model to determine the area of leak during erection and have tested it on data from both normal men (n=3) and men with venogenic impotence (n=16) undergoing dynamic infusion cavernosometry (DIC). The area of leak in the impotent group is significantly greater than in normal men at intracorporal pressures above 30 mmHg and reaches a plateau between 60 and 90 mmHg. Based on this study, we suggest that it may be necessary only to perform DIC at intracorporal pressures between 60 and 90 mmHg.
