The problem begins after an injury or prostate surgery In the study, the researchers extracted smooth muscle cells and endothelial cells from the animals' penises. The cells were then separated and grown in the laboratory on rod-shaped collagen scaffolds for support.

Dynamic infusion cavernosometry: This test is used for men with ED who have a venous leak. During this test, fluid is pumped into the penis at a predetermined rate. By measuring the rate at which fluid must be pumped to attain a rigid erection, doctors can determine the severity of the venous leak. The rich database of the Massachusetts Male Aging Study has allowed important insights to be gained into a variety of risk factors for erectile dysfunction, both psychosocial and physical. A submissive personality was associated with a higher risk of erectile dysfunction. Obesity status was also associated with the condition (p = 0.006), with baseline obesity predicting a higher risk regardless of follow-up weight loss.
