N52.03

Clinical Causes: Atherosclerosis leading to narrowing or blockage of penile arteries Damage or dysfunction of the endothelial lining of blood vessels Chronic conditions such as diabetes or hypertension that impair blood flow Pelvic or perineal trauma affecting vascular structures Venous leak caused by malfunctioning of the erectile venous system Neurovascular disorders impacting blood flow and sensation Lifestyle factors such as smoking and obesity contributing to vascular issues Medications or surgeries that impair vascular function

Key Symptoms: Difficulty achieving or maintaining an erection Reduced firmness of the erection during sexual activity Premature loss of erection Presence of a sensation of soft or flaccid erections despite sexual arousal Possible psychological effects like anxiety or reduced self-confidence In some cases, noticeable venous leakage during erection

Diagnosis Path: Medical history review focusing on cardiovascular health and sexual function Physical examination, including assessment of penile blood flow Duplex Doppler ultrasound to evaluate arterial inflow and venous leak Pharmacological testing, such as injection of vasoactive agents to observe vascular response Nocturnal penile tumescence testing to assess natural erections during sleep Laboratory tests to check for underlying conditions like diabetes or hormonal imbalances

Treatment Protocols: Lifestyle modifications such as weight loss, smoking cessation, and exercise Oral medications like phosphodiesterase inhibitors (e.g., sildenafil, tadalafil) to enhance blood flow Injection therapy with vasoactive substances directly into the penis Vacuum erection devices to promote blood flow and maintain an erection Surgical options, including penile arterial revascularization or venous ligation, in selected cases Psychological counseling or sex therapy to address emotional and psychological impacts Consideration of penile implants if other treatments are ineffective
