Could getting Joules on the Crown Jewels help with low testosterone in men?
Low testosterone levels in men is a growing problem with few answers.
A study done back in 2007 and published in the Journal of Clinical Endocrinology and Metabolism concluded "During the past two decades, testosterone levels in American men have rapidly declined."
The chart below really tells the story:
“The interesting thing we discovered was that, on average, when we measured the testosterone in the blood of a 60-year-old in 1989 it was higher than that in a different 60-year-old measured in 1995,” said Thomas Travison, PhD, of the New England Research Institutes, Watertown, Mass. “We observed the same phenomenon over a wide range of ages.”
So it seems we are not the men our grandfather's were.
When many think of the effects of low testosterone, they think of low libido, less overall drive in life, etc. Unfortunately low levels of testosterone may be more than just a lower quality of life problem. Low levels of testosterone have been linked to higher incidence of chronic disease.
A 2018 study published in the Journal Scientific Reports concluded there is a strong link between men's low levels of testosterone and having two or more chronic diseases such as arthritis, high blood pressure, and type 2 diabetes — even in the under-40s.
Further analysis showed that there was a significant "dose-response relationship" at play, which the studies author stated "means that men should be concerned about declining total testosterone, even if it has not reached a level to warrant a clinical diagnosis."
So to summarize - environmental factors seem to be at play which are driving the average level of testosterone in men lower with each subsequent generation. Low T is associated with not only lower quality of life, lower libido, lower sex drive and lower overall drive, but with higher incidence of chronic disease in a dose dependent manner.
If you are man who wants to live a high quality life, achieve your goals, overcome whatever obstacles life throws ate you; if you want to have a fulfilling and active sex life and if you want to avoid chronic disease to increase not only lifespan but health-span, it seems clear you need to employ strategies for increasing testosterone levels.
Clinical research on light therapy and testosterone looks promising
In 2013 a group of Korean researchers looked at the impact of testicular exposure of Red and Near-Infrared light. Thirty male rats were split into three groups: a control group, one group exposed to red light and the other exposed to NIR light. At the end of the 5 day trial - the untreated rats had no change in testosterone, but the rats exposed to one 30 minute treatment of light per day had significantly elevated testosterone levels.

if you are going to try red light therapy to raise testosterone, you'll want to be sure to use LEDs (rather than incandescent bulb) and to stand far enough way so as to not heat the testicles. Testicular tissue function is hindered by elevated temperature, so this is definitely one area where low heat red light LED devices shine.
