A few causes of impotence may be iatrogenic (medically caused). Various antihypertensives (medications intended to control high blood pressure) and some drugs that modify central nervous system response may inhibit erection by denying blood supply or by altering nerve activity. Antidepressants, especially SSRIs, can cause impotence as a side effect. Surgical intervention for a number of different conditions may remove anatomical structures necessary to erection, damage nerves, or impair blood supply. Some studies have shown that male circumcision may result in an increased risk of impotence, [1] [2] while others have found no such effect, [3] [4] [5], and another found the opposite.

This was thought to be useful in distinguishing psychogenic from organic impotence. This test involves placing a band around the penis and instructing the patient to wear it for 2-3 successive nights. If an erection occurs, which is expected during rapid eye movement sleep, the force and duration are measured on a graph. Inadequate or absent nocturnal erections suggest an organic dysfunction, while a normal result indicates a high likelihood of a psychogenic etiology. Other devices are available to provide similar information. Some are also able to measure rigidity (resistance to mild compression) and tumescence (size). This test is rarely used in current practice, but it can be helpful in situations in which the diagnosis is in doubt.
