Which factors are commonly implicated in erectile dysfunction?

• A. Diabetes mellitus
• B. All of the above
• C. Psychogenic factors
• D. Vascular disease

Answer: (B)

Erectile dysfunction typically results from multiple interacting factors that affect the pathways necessary to achieve and maintain an erection. Diabetes mellitus stands out as a major contributor because chronic high blood sugar damages small blood vessels and nerves, leading to reduced penile blood flow and impaired nerve signaling. Vascular disease, such as atherosclerosis of the pelvic arteries, directly limits arterial inflow or promotes venous leakage, both of which blunt the ability to sustain an erection. Psychogenic factors—like performance anxiety, stress, or depression—can also significantly interfere with arousal and the neural signals that initiate and sustain an erection, especially in the absence of strong organic disease, or they can worsen organic problems. Because erectile dysfunction is commonly multifactorial, many patients have a combination of vascular, neurological, hormonal, and psychogenic contributors. That makes all of the above the best answer, as it reflects the broad range of factors that can play a role in ED.
