A new study has found that a significant number of men who have Type 2 diabetes may have low testosterone levels, a condition that can trigger erectile dysfunction but can be treated with testosterone replacement therapy.

The study, published in the April 2007 issue of the journal Diabetes Care, looked at 355 men over the age of 30 who had Type 2 diabetes. The researchers found that 17% of these men had low testosterone levels, and an additional 25% had borderline low levels of the male sex hormone. Obesity, as measured by body-mass index and waist circumference, was strongly associated with low testosterone levels in men.

Of the men in the study who were found to have low testosterone levels, 70% reported erectile dysfunction and 63% reported low sex drive. The major symptoms of low testosterone levels tend to be low sex drive, reduced erection strength, reduced physical strength, fatigue, and changes in mood.

As we revealed in the previous blog entry “Diabetes and Erectile Dysfunction: Two New Studies,” erectile dysfunction is reported by about half of men with diabetes, with increasing age being an important factor. Testosterone levels also decline in men with age. Other factors that may play a role in causing erectile dysfunction in men with diabetes are impaired circulation from blood vessel damage and neuropathy, or nerve damage. A combination of factors is often responsible for erectile dysfunction.

Other studies have shown that men with erectile dysfunction who do not improve with use of sildenafil (brand name Viagra) are often found to have low testosterone levels. What’s more, 60% of these men do see improvement when testosterone replacement therapy is added to the sildenafil treatment. Testosterone replacement therapy in men with low testosterone levels and Type 2 diabetes has also been shown to make them more sensitive to insulin, improve their blood glucose control and cholesterol levels, and help them lose weight.

The study’s authors have called for larger studies to see whether testosterone replacement therapy can improve quality of life and diabetes control in men with Type 2 diabetes. Meanwhile, if you have Type 2 diabetes and symptoms of low testosterone or erectile dysfunction, you may want to talk with your doctor about having your testosterone level tested. If you are a candidate for testosterone replacement therapy, several options exist, including injections, patches, and gels.

  2. I am a type 2 & on testosterone replacement injections. I’m 68 & it works. If I’m one week late I can tell the differance. Tried the patches & gels they arn’t as effective as the shots. If your very active perpiration can cause problems with the patches sticking. Viagra works but levitra works best for me with the least amount of side effects.

Tested 150 Testesterone level. Doctor wanted me retested fasting next morning and wait 2 weeks for next visit. Can’t wait…I want the shot. Want all the benefits it provides.

  15. I am borderline diabetic, age 54 - it started when I began applying Androgel testosterone gel daily for low testosterone. Because of an increase in PSA levels I have been told to stop the Androgel. Noticed a lack of sex drive. Don’t know what to do and neither do my doctors. Is the Androgel associated with increasing blood sugar in men? Saw a web site where it is in women.

  17. My husband refuses to go to the Dr to discuss his low testosterone problems. He is a brittle diabetic. He has had Diabetes for around 25 years. His testosterone levels were very low. He has had glucose levels as low as 41 @ night and . during the day his levels can go as high as 495. He has lost weight, which is good,but he refuses to go to an endocrinologist due to several past negative experiences. He is a 71 year old insuline dependent diabetic who sleeps most of the day,always tired,mostly sedentary, has erectile dysfuntion, was given Rx of Viagra tx but no testosterone replacement. He stopped taking the visgra because he says he sees no difference. Now he has a serious problem= forskin is sticking on his organ and he is having difficulty passing urine. Can you give me some advise? I want to help him be happy and live a better quality of life, rather than see him depressed, tired, sleepy. going through dangerous life threatning glucose levels. Thanks;
    I.D

  18. My husband is in his late 50’s and has experienced much difficulty controlling his Type 2 Diabetes in spite of Lantus and other meds. His PCP wasn’t responsive to our questions about the possibility of Low T. We were persistent and found a MD who not only listened, but suggested the testing before we even asked for it. Still waiting for the results but we’ll be very surprised if this is not what’s happening as he has all the symptoms. Thank you all for sharing your experiences. Just knowing there are effective therapies is making things easier already!

  19. Which drug company employs you?

  20. Hello, I started to have a raised blood sugar count, at the same time that I saw the TV commercials about Low T. After doing injections, and just coming off vacation, where I did not eat properly, this AM my blood level was 63. Did not trust that, so I took it again, 59. I then went on the web, found this site, and voila, just what I suspected. I’m 56. The “vitamin T” is good stuff. I now have the energy to get my body back in shape so that the fat band around my midsection will stop stealing my life away.
    Thanks for the info.

  21. I am 40 years old and I have low testosterone (260ng/dl) . Recently I had bloddwork done and I might have Type 2 diabetes. I have to go back for further testing. I don’t understand, I eat healthy, exercise 5 days a week and I never had any issues. I take Testim for the low T and it really does not work. In the past I had the injections which works but then I developed the “female side effects”. This is so frustrating!

  22. Chris, find somebody to treat you that knows what he is doing. Increasing your T can cause your Estrogen levels to rise also. Can also cause your testicles to shrink because your bringing it in from an outside source. Both of these problems are easily treated when you get your T replacement.

  24. I am having problems trying to find ANY studies where low levels of testosterone were diagnosed first, with testosterone was prescribed, yet, the levels didn’t go above 300-350 and type 2 diabetes followed (at least with me) about 5 years later. So, can anyone provide studies with my situation? If so, I am wondering if properly prescribed levels of testosterone would possibly rid my diabetes situation. Also, besides the diabetes following about 5 years later, I developed cholesterol issues, high blood pressure, mild sleep apnea etc. From what I can find is low level testosterone can cause all of these problems. So why do doctors only prescribe doses of testosterone which raises the levels to 300-350 versus 800+ where a normal healthy male is at ages 20-30 years old? It seems to me that keeping the testosterone levels low, keeps my other medical issues too. I guess I am going back to my original question here, are there any studies being done with people like me?
