Diabetes and ED

“Diabetes” is a disease in which insulin is not secreted or works poorly and the concentration of sugar in the blood continues to be too high. A fasting blood glucose level of 126 mg/dl or higher or HbA1c of 6.5% or higher increases the likelihood of diabetes. At first, it is often taken lightly because it has no subjective symptoms, but it takes a long time to have an adverse effect on various parts of the body. When severe, it can cause serious complications such as blindness, renal dysfunction, and gangrene of the hands and feet. Diabetes is also one of the diseases highly associated with “erectile dysfunction (ED)”.

Why are people with diabetes more likely to have ED?

For a normal erection, the brain, nerves, corpus cavernosum, blood flow, etc. must function without problems. Diabetic ED is often a combination of multiple problems, including those listed below.


An erection is caused by the sexual stimulation felt in the brain being transmitted to the penis, but diabetes makes it more likely that the neural circuit will be damaged.

Corpus cavernosum dysfunction

“Smooth muscle relaxation” is also essential for an erection. However, due to diabetes, the activity of “endothelial nitrogen monoxide synthase” (eNOS) decreases in endothelial cells such as the corpus cavernosum artery, which makes relaxation less likely to occur.


Arteriosclerosis in blood vessels throughout the body is a typical symptom of diabetes. In particular, sclerosis from the internal iliac artery to the penile artery leads to a significant decline in erectile function.

The capillaries of the corpus cavernosum are the smallest blood vessels in the body, and the blood flow is most likely to decrease due to arteriosclerosis. Conversely, the symptoms of ED are also a sign that arteriosclerosis is progressing in the body due to diabetes and other illnesses, aging, stress, drinking, and smoking.

ED caused by physical causes as described above is called ” organic ED “. In addition, there are ” psychopathic ED ” due to the depressive tendency caused by diabetes and ” drug-induced ED ” due to diabetes drugs and antihypertensive drugs, and there are many factors that induce ED compared to other diseases. You can say that.

Diagnosis method of diabetic ED

Whether or not it is diabetic ED is judged by estimating the degree of progression of arteriosclerosis from the value of hemoglobin A1c (HbA1c), which is an index of whether the blood glucose level can be controlled, and the period after becoming diabetic. However, it is known that the complication rate of diabetes and ED is very high, so it is natural to think that diabetes and ED are co-occurring if there are subjective symptoms such as bending or not becoming sufficiently stiff.

What is the treatment for diabetic ED?

We do not perform any extra tests, and if you have diabetes, check the hemoglobin A1c (HbA1c) level and the presence of other diseases, check the medicines you are taking, and use the oral ED treatment together. We have received it and judged the effect.
Even for people with diabetes, the combination of PDE5 inhibitors, such as Viagra, has a high probability of significant improvement and a wealth of treatment experience.
When you come to the hospital, you can check it smoothly if you bring the blood test result and the medicine notebook.

To prevent diabetic ED from getting worse!

In order to prevent the progression of diabetic ED, it is necessary to manage diabetes well, continue dietary habits, exercise, and treatment with medicines, and maintain the hemoglobin A1c level at most below 7. is important. This is because if the blood sugar level continues to be high, it will damage nerves and blood vessels and promote ED.

In addition, if you have hypertension, hyperlipidemia, depression, etc. associated with diabetes, it is important to adequately treat them.
