Low Testosterone Diabetes and Erectile Dysfunction – Are they related?


Fun Colored Supplements

It turns out that men who have Type 2 Diabetes, that also have erectile dysfunction have not been very widely studied. They have low testosterone levels, causing low sex drive and erectile dysfunction. This is not true of all men who have low testosterone but it is an overwhelming number and appears to be growing according to the National Institute of Health. In this post I will discuss all of these issues and how they appear to be related, according to the information I have found in my research. FYI, the reason I have done all this research was originally because I had all of these issues. Now I want to provide you all information that I have discovered in that research.

Diabetes and Erectile Dysfunction(ED) – How are they related?

Even though diabetes and erectile dysfunction (ED) are two totally different conditions, they have been shown to be very closely related. ED is defined as having a tough time achieving or keeping an erection. Many medical and health sites  have shown that men who have diabetes are 2 – 3 times more likely to develop ED. But, when men age 45 and under develop ED, there is a good chance it is a sign of type 2 diabetes and most likely low T.

We know diabetes happens when you have too much sugar running around in your bloodstream. There are two types of diabetes: type 1 diabetes, which affects less than 1 out of 10 of those who have diabetes, and type 2 diabetes, which accounts for over 9 out of 10 of all diabetes cases. Type 2 diabetes typically develops as a result of when you are overweight and probably not very physically active, like I wasn’t. Approximately 30 – 40 million Americans have diabetes, and unfortunately more than half of them are men. Note: I am one of them. Dangit!!

Approximately 10 percent of men ages 40 to 80 have severe ED, and another 25 percent have moderate ED. ED usually becomes more common as us men age, but it isn’t a for sure part of aging. That is 35% of all men after age 40, probably have Erectile Dysfunction. Ouch!!

Low T and Erectile Dysfunction(ED) – How are they related?

As we have discussed in other posts on my site, testosterone is a hormone found in both men and women. Men have much higher levels of testosterone than women. Production of testosterone increases during our early ages, especially in our teens, and then starts to decrease after age 30 – 40. For each year over about age 30, the level of testosterone in men starts to slowly drop at a rate of around 1 – 2 percent per year. A decrease in testosterone level is a natural result of aging and does not mean you will definitely also have ED.

One of the biggest things that men worry about, with declining testosterone levels, is the chance that their sexual appetite and performance may be affected. As men age, they can experience a number of symptoms related to sexual function that may be a result of lowered levels of testosterone.

These can include:

  • a reduced desire for sex
  • fewer erections that happen on their own, like when your are asleep
  • lower sperm count

Erectile dysfunction (ED) is not always caused by insufficient testosterone production. In cases where ED accompanies lower testosterone production, hormone replacement therapy will most likely help your ED, but the side effects are not pleasant. That is why I will be recommending only the best quality testosterone boosters in a new post very soon. Please keep an eye out for that and many more product reviews on my site.

Type 2 Diabetes Treatments – What are the effects on Low T and ED?

Since I have Low T and Type 2 Diabetes, I have spent a lot of time researching the medications I have been prescribed for my Diabetes. Unfortunately, the side effects of some are directly related to Low Testosterone and ED.

My Endocrinologist, who is amazing, prescribed Metformin initially. It turns out that Metformin leads to significant reduction in testosterone levels, sex drive and induces low testosterone-induced erectile dysfunction. That is an unpleasant side effect that I wasn’t aware of in the beginning. To battle that little side effect, I am now taking Glipizide which is sulfonylurea, that supposedly leads to significant elevation in testosterone levels, sex drive and erectile function. Still waiting for those results.

I am currently looking for natural supplements/boosters that will also help with my low t and ED, while medically treating my diabetes. There are many of those products on the market and when I find the best ones, I will post full detailed reviews for them.

Does Low Testosterone Treatment Help Erectile Dysfunction?

Testosterone Therapy Treatment (TRT) does not improve erections in men with normal testosterone levels. And studies show that it does not help men with low testosterone levels if ED is their only symptom. However, if you have Type 2 Diabetes and low Testosterone, increasing your Testosterone level will most likely help with your ED, as long as there is not another issue that can cause ED, such as low blood flow to the penis. This is a result of other conditions, like hardening of the arteries, high blood pressure, and high cholesterol. All of these conditions narrow the blood vessels and reduce blood flow to the penis.

Low testosterone may affect the desire for sex, but it rarely, on its own, causes ED.

There are however, natural herbs and supplements that have been shown to increase low testosterone and help ED, on the market today. Coming soon will be my next post with recommendations for the best options. UPDATE: I have done many testosterone supplement and booster reviews since this post.

The Not Surprising Conclusion

In summary, Low testosterone, Diabetes,  and Erectile Dysfunction are definitely related. You can have low T and not have ED, but if you have Type 2 Diabetes, you are most likely going to develop both. If you have belly fat and you are overweight, you are most likely going to have all three issues. More on that to come in future articles.

Best thing to do for all of these issues is to eat the right foods and get some consistent exercise. More on that in other articles on my site.

  1. very interesting and informative post. I had no idea that diabetes and erectile dysfunction are related. Now I now that. I will share this post with people that would like to have this information. Thank you so much.

  2. Good health information ! I know Testosterone reduction not only affects reproductive health, it also affects bones, muscles, skin, hair and nails. Men need to know the causes of testosterone depletion in the body so that there are timely remedies to improve the physiology and bring about the best health.

    Thank you for the very useful information!

  3. That was a good post to help people understand how this two are related. Nice calling for those who are not diagnosed with diabetes to really take care of their health including me.

    • Thank you for reviewing this post. Even if you ever get diagnosed with pre-diabetes, it is time to get serious on your health or diabetes will definitely follow.

  4. A very informative post. This raised many questions in my head, e.g, why erectile dysfunction is not linked to type I diabetes? I also wonder the effect of Metformin on testosterone level, the side effect was not studied before you started using it. This could be a novel finding?
    I really appreciate your struggle though 🙂
    keep sharing such informative posts.
