ED treatment for diabetic men
Find the best options for ED if you have diabetes.
There are several ways diabetes can affect a man sexually – a key one being erection problems. And this is because diabetes and erectile dysfunction are physically linked.
So is there a best ED treatment for men with diabetes? In short yes – men with diabetes can take Viagra, but there are other options that might be slightly better suited to them (depending on their individual health needs and how they respond to treatment).
Diabetes has been linked to a range of sexual problems in men, including low libido, ejaculation and – most commonly – erectile dysfunction.
The main reason is physical: good blood flow and nerve transmissions are vital for erections to happen, and diabetes can interfere with both of these functions. But there’s a psychological element too. If you’ve got diabetes, you might be more aware of these potential problems – even if they aren’t happening yet – which could lead to psychological ED.
Diabetes can cause erectile dysfunction by interfering with your internal ‘plumbing’. Over time, high blood glucose can damage blood vessels, reducing blood flow to the penis and making it harder to get and maintain an erection.
There’s another way that diabetes can lead to ED too. Over time, severe cases of diabetes can lead to nerve damage, and affect the communications that control erectile function. When men become aroused, signals from the brain help blood vessels near the penis to widen and relax, so blood can get through and ‘fuel’ an erection. With diabetes-induced nerve damage, this process can become disrupted, making erections harder to achieve.
If you’ve got diabetes, there are ways you can treat erectile dysfunction and stop it from getting worse. One is to stick to your diabetes treatment plan – this will help to prevent your diabetes from progressing, causing further damage to blood vessels and making ED symptoms worse.
Another is to eat a healthy diet and exercise regularly. Doing this can help to improve your diabetes control, but also has the added effect of improving vascular health (which can contribute towards better erections).
And then there are treatments that can help increase blood flow to the penis, such as Viagra. While these don’t treat the instigating cause, they can help to tackle the problem of ED itself.
According to Diabetes UK, men with diabetes are three times more likely to develop erectile dysfunction. Studies into how common erectile dysfunction is in diabetic men have suggested prevalences of 52% , and in men with type 2 diabetes specifically, 66% and 59%. A paper published by the American Diabetes Association suggested a prevalence of between 35-75%, compared with 26% in the general population.
So we know there’s a strong correlation between ED and diabetes, which indicates a higher risk. But the exact extent of the risk is debatable because other factors (many of which can be present alongside diabetes) can contribute towards erectile dysfunction too. It’s rarely possible to single out diabetes as the sole contributing factor.
It’s thought that diabetes can cause ejaculation problems by interfering with nerve transmissions from the brain. Severe diabetes can lead to autonomic nerve damage, which impacts the muscles controlling how semen is released.
This can result in a condition called retrograde ejaculation, where semen travels backward into your bladder rather than out of your penis. It can also cause a general loss of sensation or reduced ejaculatory control. If you notice these changes, it’s a key sign to speak with your doctor about your blood sugar levels.

If you’ve got diabetes, the best pill to treat erectile dysfunction can depend on a few factors, including whether you’re on blood pressure lowering treatment, how severe your ED is, and any other medications you’re taking.
Several ED pills, including sildenafil (Viagra), vardenafil and tadalafil (Cialis) have been shown in clinical studies to be effective at treating ED in men with diabetes. They are safe to take alongside standard diabetes medications like metformin or insulin.
Sildenafil and Tadalafil are the most commonly prescribed options. Tadalafil is particularly popular because it’s available as a daily low-dose pill, offering continuous support without needing to plan ahead. Generic Vardenafil is another excellent option, although its original branded version (Levitra) has been discontinued, the generic equivalent works identically to boost blood flow when you need it.
Sildenafil, which is also known by the branded name Viagra, is an effective treatment for diabetic men with erectile dysfunction to use. One study into the use of the drug in just over 100 men with ED and diabetes found that 55% were able to have at least one successful sexual intercourse’ after using it (compared to 15.6% in the placebo group).
Another study analysing sildenafil use in just over 250 men with diabetes and ED reported improved erections in 56% of participants (compared with 10% in the placebo group).
So if you have diabetes and ED, Viagra can be an effective treatment for you. But if you have diabetes and Viagra doesn’t quite work well enough or gives you side effects, you might be recommended a different treatment, like Vardenafil, rather than a higher dose of sildenafil. This is because higher doses of ED drugs like sildenafil pose a higher risk of side effects or interactions with other treatments.
There are certain patient criteria in the UK that, if met, mean that someone with erectile dysfunction is entitled to branded treatment on an NHS prescription (which is free if you’re entitled to free treatment).
One is that if you have diabetes and erectile dysfunction, you can get an NHS prescription for Sildenafil, the generic version of Viagra. To access the treatment, you’ll need to make an in-person appointment with your GP. They can normally prescribe it without referring you to a specialist if you have diabetes.
Because diabetes can cause damage to blood vessels and the nervous system, it’s not always possible to fully reverse erectile dysfunction related to it. Sometimes, you might need to use ED treatment long-term to counter the problem.
But it is possible to improve erectile dysfunction symptoms associated with diabetes by controlling your blood sugar and following your diabetes treatment plan.
Some men who have diabetes and intermittent erectile dysfunction may find that their symptoms pass if they follow a healthier diet, maintain good blood sugar control and get plenty of exercise. If you have diabetes and think you might be experiencing ED though, it’s worth seeing a doctor so they can make sure your diabetes is well-controlled – as well as give you advice and treatment recommendations for your ED symptoms.
