Sexual dysfunction in male stroke patients: correlation between brain lesions and sexual function

Area of Science:

• Neurology
• Sexual Medicine
• Rehabilitation

Background:

• Stroke significantly impacts patients' quality of life, extending beyond physical and cognitive deficits.
• Sexual dysfunction is a common yet often overlooked consequence of stroke.
• Understanding the specific neurological correlates of sexual dysfunction post-stroke is crucial for comprehensive patient care.

Purpose of the Study:

• To investigate the prevalence and nature of sexual dysfunction in stroke patients.
• To determine the influence of brain lesion location on sexual function following a stroke.
• To identify key factors contributing to sexual inactivity in stroke survivors.

Main Methods:

• A survey was administered to 109 stroke patients and 109 age-matched controls.
• The International Index of Erectile Function (IIEF-5) and custom questions assessed sexual desire, erectile function, ejaculatory function, and satisfaction.
• Correlation analysis was performed between questionnaire results and the anatomical location of brain lesions.

Main Results:

• Stroke patients exhibited significantly lower erectile function (IIEF-5 score 5.89) compared to controls (10.67).
• A majority of stroke patients reported decreased sexual desire and intercourse frequency, with ejaculation disorders noted.
• Lack of sexual desire was the primary reason for reduced sexual activity (59.4%).
• Lesions in the right cerebellum were associated with ejaculation disorders, while left basal ganglia lesions correlated with decreased sexual desire.

Conclusions:

• Stroke leads to significant impairments in sexual desire, erectile function, and ejaculatory function.
• Reduced sexual desire is the main driver of sexual inactivity post-stroke.
• Specific brain lesion locations, such as the left basal ganglia and right cerebellum, are linked to particular sexual dysfunctions, highlighting the neuroanatomical basis of sexual health after stroke.
