Erectile dysfunction (ED) is the inability to achieve or maintain a rigid penile erection suitable for satisfactory sexual intercourse, which substantially reduces the quality of life for patients and their partners. While ED prevalence increases with age, various co-morbidities such as depression, obesity, lack of exercise, diabetes mellitus, hypertension, dyslipidaemia, and cardiovascular disease, are associated with the condition7. Caffeine has been reported to associate with multiple physiological effects on vascular function and hormonal balance that might influence sexual function. Nonetheless, the meta-analysis of 4 cohort studies comprised 51,665 male cohort members by Karimi et al. (2024) revealed no significant relationship between coffee consumption and the risk of ED (relative risk [RR]: 0.94, p=0.999)8.
