Question 1

Q: A 41-year-old male presents with complaints of inability to achieve proper erections during sexual intercourse. He reports that there were no abnormalities until last month, when on one occasion he tried having sex while he was drunk. He was not able to achieve a proper erection at that time, and since then, on four other occasions, he has been unable to have an erection during attempted sex. He reports that his morning erections are fine and erections during masturbation were also normal. He is a diabetic, and the blood reports show FBS-103 mg/dl, HbA1C-6.6. His BP was 138/88 mm Hg. What is the likely cause of his erection disturbances?

Anxiety. **Explanation** The clinical presentation points toward **Psychogenic Erectile Dysfunction (ED)**, specifically triggered by **Performance Anxiety**. **Why Anxiety is the correct answer:** The hallmark of psychogenic ED is the **situational nature** of the symptoms. The patient reports normal morning erections (nocturnal penile tumescence) and normal erections during masturbation. This confirms that the physiological mechanisms (neurological, vascular, and hormonal) required for an erection are intact. The dysfunction began after a single failure (likely due to alcohol's sedative effect), leading to a "vicious cycle" where the fear of failure (performance anxiety) triggers a sympathetic nervous system surge, preventing the parasympathetic response necessary for an erection. **Why other options are incorrect:** * **Diabetes & Hypertension:** While both are common causes of *organic* ED due to microvascular and endothelial damage, organic ED is typically gradual in onset and characterized by the **absence** of morning or masturbatory erections. This patient’s HbA1C (6.6) and BP are relatively well-controlled. * **Alcohol use:** While acute alcohol ingestion can cause temporary ED (as seen in his first episode), it does not explain the subsequent failures while sober, especially when nocturnal erections remain preserved. **Clinical Pearls for NEET-PG:** * **Organic vs. Psychogenic ED:** If spontaneous morning erections are present, the cause is almost always psychogenic. * **Performance Anxiety:** This is the most common cause of psychogenic ED in young and middle-aged men. * **Nocturnal Penile Tumescence (NPT) Test:** Used to differentiate organic from psychogenic ED. A positive NPT (erections during sleep) confirms a psychogenic etiology. * **Diabetes:** The most common organic cause of ED due to a combination of neuropathy and angiopathy.
