Can men with erectile dysfunction take metformin?

Even though metformin lowers testosterone levels, it is overall beneficial for men experiencing erectile dysfunction. In addition to controlling blood sugar levels, taking metformin has the following positive effects:

  • Metformin is an insulin sensitizer. It reduces insulin resistance, enhances endothelium-dependent vasodilation, and increases blood flow to improve erectile function. 

  • Metformin increases the activity of an enzyme called nitric oxide synthase in erectile tissues, which is needed to make nitric oxide. Nitric oxide plays an important role in triggering erections.

  • Metformin regulates sympathetic nerve activity in the penis.

If you are worried that metformin may cause erectile dysfunction or sexual dysfunction, talk to your healthcare provider about alternative diabetes medications

Can a diabetic man get an erection?

A diabetic man may find it difficult to get an erection. Diabetes is a known risk factor for erectile dysfunction (an inability to get or keep an erection). The disease causes damage to the tiny blood vessels and nerves in the corpus cavernosum (penile tissue). This can decrease the response to sexual arousal and reduce blood flow to the penis, causing problems with erections. 

Studies have found that diabetic men are three times more likely to develop erectile dysfunction compared to men who don’t have diabetes. In addition, diabetes is often accompanied by other medical conditions, such as obesity, high blood pressure, high cholesterol, and smoking, which are all independent risk factors for erectile dysfunction.
