Erectile Dysfunction among Yemenis: Does Chewing Khat Play a Role?

Area of Science:

• Urology
• Andrology
• Public Health

Background:

• Khat (Catha edulis) is a plant with stimulant properties, widely consumed in Yemen and parts of Africa.
• Erectile dysfunction (ED) is a significant health concern with multifactorial causes.
• Understanding the specific etiology of ED in the Yemeni population is crucial for targeted interventions.

Purpose of the Study:

• To determine the primary causes of erectile dysfunction (ED) in Yemeni patients.
• To investigate the potential association between Khat chewing and ED in this demographic.
• To identify risk factors contributing to ED in Yemen.

Main Methods:

• A cohort of 236 male patients presenting with ED at the University of Science and Technology Hospital were evaluated.
• Penile Doppler ultrasonography was utilized for diagnostic assessment.
• Patient biodata and health information were collected through medical records and mobile interviews.

Main Results:

• Psychological factors were identified as the leading cause of ED, accounting for 72% of cases.
• Pathological ED, including venous leakage (19%) and arterial disease (9%), increased with age.
• A significant association was found between pathological ED and comorbidities like heart disease and diabetes (p<0.05).
• Despite 81% of ED patients reporting Khat use, no statistically significant correlation with ED was established (p>0.05).

Conclusions:

• Psychological issues are the predominant cause of ED in Yemen, especially in younger individuals.
• While current data does not link Khat use to ED, it cannot be definitively excluded.
• Further large-scale, case-control studies are necessary to elucidate the role of Khat in ED etiology.
