Arginine and erectile dysfunction

This study looked at the safety and effectiveness of arginine in the treatment of erectile dysfunction (ED). It concluded that arginine is safe and effective in treating mild or moderate ED. 

ED is when you cannot get or keep an erection firm enough to have intercourse. ED can occur from a physical cause. This may include disease, injury or side effects of drugs. Emotional issues, psychological issues or mental health issues can also worsen ED symptoms. ED is treated by lifestyle changes, medications, devices or surgery. 

ED medications do not work for every patient. Some patients have side effects such as headaches. Arginine may be more effective in these patients. 

10 studies looking at arginine as a treatment for ED were assessed. These included 540 patients. Improvements in ED were assessed through a questionnaire. Side effects were also assessed. 

Questionnaires showed higher satisfaction with arginine than with no treatment for ED. Satisfaction was highest in supplements containing arginine. These also improved intercourse satisfaction. Treatment with arginine alone did not affect satisfaction with intercourse. Arginine did not affect sexual desire. Being able to orgasm was improved by both arginine and supplements containing arginine. 8.1% of patients taking arginine had side effects. These included: headache, insomnia and itching. 

This study concluded that arginine can improve mild or moderate ED. 

The authors note that the studies compared varied. This may affect this study's results.
