Exploring the interconnectedness of multiple sclerosis and erectile dysfunction: mechanisms and management strategies

Area of Science:

• Neurology
• Urology
• Psychology

Background:

• Erectile dysfunction (ED) is a prevalent complication in men diagnosed with multiple sclerosis (MS).
• The etiology of ED in MS is multifactorial, involving neurogenic, autonomic, vascular, inflammatory, and psychosocial pathways.
• Understanding these pathways is crucial for effective management strategies.

Purpose of the Study:

• To synthesize epidemiologic data on ED prevalence and risk factors in men with MS.
• To map the mechanistic pathways linking MS-related central and spinal lesions, autonomic-endothelial dysfunction, and psychosocial factors to ED.
• To propose a stage-based care algorithm for managing ED in MS patients.

Main Methods:

• Systematic review and meta-analysis of over 30 studies on ED prevalence in MS.
• Analysis of mechanistic pathways connecting MS pathology to ED phenotypes.
• Development of a clinical care algorithm integrating diagnostic and therapeutic approaches.

Main Results:

• Pooled ED prevalence in men with MS is approximately 50%.
• Higher disability, lower urinary tract symptoms (LUTS), and depression are associated with increased ED risk.
• Phosphodiesterase-5 inhibitors (PDE5i) are common first-line treatments, but MS-specific data are limited and responses vary.

Conclusions:

• ED is highly prevalent in men with MS, linked to disease severity and comorbidities.
• A comprehensive care approach integrating neuro-urological and psycho-sexological support is recommended.
• Further research is needed to optimize ED treatment strategies in the MS population.
