[Neurogenic etiology in patients with erectile dysfunction]

Area of Science:

• Neurology
• Urology
• Internal Medicine

Context:

• Erectile dysfunction (ED) is a common condition, particularly in aging populations, with multifactorial origins.
• Neurological factors, originating from either the central or peripheral nervous system, significantly contribute to ED pathogenesis.
• Systemic diseases, medications, and psychological factors also play a role in the development of ED.

Purpose:

• To provide a comprehensive review of the most relevant causes of neurogenic erectile dysfunction.
• To detail the etiopathogenic mechanisms underlying these neurological causes of ED.
• To outline the most appropriate current therapeutic approaches for each specific case of neurogenic ED.

Summary:

• Neurogenic erectile dysfunction can arise from central nervous system conditions like tumors, stroke, Parkinson's disease, multiple sclerosis, and dementias.
• Peripheral nervous system disorders affecting afferent or efferent pathways of the erection reflex can also lead to ED.
• Understanding the specific neurological underpinnings is crucial for effective management.

Impact:

• Accurate diagnosis of erectile dysfunction requires identifying underlying etiopathogenic factors, including neurological ones.
• Recognizing neurogenic risk factors enhances understanding of physiopathologic mechanisms.
• This knowledge facilitates improved diagnostic, prognostic, and therapeutic strategies, particularly for patients refractory to first-line treatments.
