Men with type 2 diabetes are about twice as likely to have low testosterone, and the two conditions feed each other. Extra body fat and insulin resistance lower testosterone, while low testosterone makes blood sugar harder to control. Watch for low libido, fatigue, and lost muscle. A simple blood test confirms low T, and weight loss, exercise, or physician-guided therapy can help.
Could your diabetes and low testosterone be related? For many men, the answer is yes. The two conditions are closely linked, and they often make each other worse. If you have diabetes and you feel tired, flat, or less interested in sex, low testosterone may be part of the picture.
Are diabetes and low testosterone connected?
Yes. Diabetes and low testosterone are strongly linked, especially in men with type 2 diabetes. According to the American Diabetes Association guidance on sexual health, men with type 2 diabetes are about twice as likely to have low testosterone as men without it.
This connection works in both directions. Diabetes and excess weight can lower how much testosterone the body makes, and low testosterone can make blood sugar harder to control. Research published in Frontiers in Endocrinology describes this as a two-way relationship that can build into a cycle over time.
If you are noticing the early signs of hormone trouble, a good first step is to learn more about the symptoms and causes of low testosterone in men so you know what to bring up with your doctor.
Why does diabetes lower testosterone?
A few things happen at once. Extra body fat is one of the biggest drivers. Fat tissue can change testosterone into estrogen, so the more weight a man carries, the lower his testosterone tends to drop. As weight goes up in men with obesity, testosterone often falls even further.
Insulin resistance plays a role too. A large review of men with type 2 diabetes found that low testosterone is commonly seen alongside diabetes and the metabolic syndrome, and that it tends to mark men with a worse overall metabolic profile, as reported in a study indexed by the National Library of Medicine. In plain terms, blood sugar problems and low hormone levels often travel together.
What are the symptoms of low testosterone?
Low testosterone often shows up first in the bedroom. Many of the symptoms involve libido, such as low or no interest in sex, along with trouble getting or keeping an erection. These signs overlap heavily with diabetes, which is one reason low testosterone is so easy to miss.
Other common symptoms include:
Less interest in sex, or erectile dysfunction
Chronic fatigue and low energy
Lower muscle mass and strength
More body fat, especially around the middle
Low or depressed mood and trouble focusing
Because these symptoms look like many other conditions, they often go unexplained for years. The Mayo Clinic notes that when the body does not make enough testosterone in adulthood, early signs can include less sex drive, less energy, and depression, as described in its overview of male hypogonadism. If several of these sound familiar, it is worth getting checked.
How is low testosterone diagnosed?
Low testosterone is simple to identify. To find out if you have it, you usually just need a blood test that measures your testosterone level. Because levels shift through the day, doctors often draw blood in the morning and may repeat the test to confirm the result before making any decision.

How do you manage diabetes and low testosterone together?
The best foundation is the same for both conditions. Controlling your weight, eating well, and exercising regularly can all help manage type 2 diabetes and support healthier testosterone. These steps work because they attack the shared root causes: excess fat and insulin resistance.
For some men, lifestyle changes are not enough on their own. When that happens, treatment may include weight loss support or testosterone therapy guided by a physician. A University at Buffalo study reported that, among men who were treated, about one-third saw remission of their diabetes and nearly half reached normal glucose regulation, according to research summarized by the University at Buffalo. Results like this are promising, though they vary from person to person.
Treating low testosterone is one part of a larger plan. Our full range of men's health services is built to look at hormones, metabolism, and overall vitality together, rather than one symptom at a time.
Frequently Asked Questions
How can I increase testosterone if I have diabetes?
Start with the basics that also help blood sugar: lose excess weight, eat a balanced diet, move your body most days, and sleep well. These habits can naturally support testosterone. If levels stay low after lifestyle changes, talk with a doctor about whether testosterone therapy is right for you.
Can diabetes cause erectile dysfunction?
Yes. Diabetes can affect nerves, blood flow, and hormone levels, all of which matter for erections. Low testosterone often adds to the problem. Because the causes can overlap, men with diabetes and erectile dysfunction should get checked rather than assume one single cause.
Does low testosterone make diabetes worse?
It can. Low testosterone is linked with more insulin resistance and a harder time controlling blood sugar. That is why the two conditions can feed each other. Identifying and treating low testosterone is sometimes part of a broader plan to improve metabolic health.
Should men with diabetes get their testosterone checked?
It is reasonable to ask. If you have diabetes and notice fatigue, low sex drive, erectile dysfunction, or loss of muscle, a simple morning blood test can show whether low testosterone is part of the picture. Bring your symptoms to your doctor so testing can be tailored to you.
Is testosterone therapy safe for diabetics?
Testosterone therapy is not right for everyone, and a doctor will review your full health history first. Some conditions can make it a poor choice. When prescribed and monitored properly, it can help relieve symptoms of low testosterone. The decision should always be made with a qualified physician.
To find out more about the link between low testosterone and diabetes, talk with your doctor. If you think you may have low testosterone, getting tested is a simple next step. Results vary by individual, so work with a provider to find the plan that fits you best.
