These studies suggest that erectile dysfunction is common in men with diabetes, is multifactorial and more severe, and requires a holistic and multimodal treatment approach including glycemic control, lifestyle modifications, and various therapies.

Erectile dysfunction (ED) is a prevalent complication among men with diabetes, with studies indicating that more than half of diabetic men are affected. A systematic review and meta-analysis of 145 studies found that the overall prevalence of ED in diabetic men is 52.5%, with a higher prevalence in Type 2 diabetes (66.3%) compared to Type 1 diabetes (37.5%). This prevalence is significantly higher than in non-diabetic men, with diabetic men having approximately 3.5 times higher odds of experiencing ED .
Several risk factors contribute to the high prevalence of ED in diabetic men. These include advancing age, longer duration of diabetes, poor glycemic control, hypertension, hyperlipidemia, sedentary lifestyle, smoking, and the presence of other diabetic complications . The pathophysiology of diabetes-induced ED (DIED) is multifactorial, involving mechanisms such as elevated advanced glycation end-products, increased oxidative stress, impaired nitric oxide synthesis, and neuropathic damage .
Interestingly, even men with prediabetes are at a higher risk of developing ED. A meta-analysis of observational studies found that men with prediabetes have a 1.62 times higher prevalence of ED compared to men with normoglycemia. This association is particularly strong in younger men (mean age < 50 years).
ED significantly impacts the quality of life of diabetic men, often leading to symptoms of depression and anxiety. These psychological effects can further exacerbate the condition, creating a vicious cycle that affects both the individual and their partner's sexual experience and overall quality of life.
The management of ED in diabetic men requires a holistic approach. Optimized glycemic control and management of associated comorbidities are essential. First-line treatment typically involves phosphodiesterase type-5 (PDE5) inhibitors, which have been shown to be effective and safe for diabetic men . For non-responders or those contraindicated for PDE5 inhibitors, second-line treatments include transurethral prostaglandins, intracavernous injections, and vacuum devices. Penile implants are considered a third-line therapy for those who do not respond to other treatments .
Emerging therapies aim to address the underlying mechanisms of DIED. Research is ongoing to develop treatments that can correct or mitigate the multifactorial causes of ED in diabetic patients. Additionally, the identification and treatment of hypogonadism, which is commonly found in diabetic men, can enhance the effectiveness of existing therapies .
Erectile dysfunction is a common and distressing complication of diabetes, significantly affecting the quality of life of those affected. The condition is multifactorial in nature, with various risk factors and underlying mechanisms contributing to its prevalence. Effective management requires a comprehensive approach that includes lifestyle modifications, optimized glycemic control, and a range of therapeutic options. Ongoing research and emerging therapies hold promise for improving the management and outcomes of ED in diabetic men.
