This is an awesome topic, and ironic too. I just got done talking about this with my naturopathic doctor. He knows all about it and said that is another reason why our ancestors had higher testosterone. That our male ancestors had direct exposure to the sun on their testes which caused a huge jump in testosterone. This is actually a big and under looked issue with testosterone. If males today went outside more, they would have more testosterone.
It is truly amazing how the seasons work. In the book "lights out", and many other biology books the authors describes how in the summer is the time for reproduction. They also describe how animals are hornier in the summer because the vitamin D adds significantly more testosterone. Back in the day before lightbulbs most people had kids in the spring months because they reproduced in the late summer months like july and august when men had the highest testosterone levels. I know that it is a proven fact vitamin d increases testosterone. I think there have been more studies on this, but my naturopath did his own studies with hypogonadal men. He gave these men 10,000 iu's of vitamin d for 10 days and their testosterone doubled.
When I am in the sun nude, I immediately get an erection. An interesting Idea I just thought of is what if you could just rub vitamin d cream on your testes? That would be a natural and awesome technique to increase test in the 21st century.
My testosterone needs reduction if anything, but I have noticed that being nude outdoors is awesome. Aside from getting aroused I would love to be au natural 24/7
No, never say you need reduction. Most men have low testoserone and would kill to have higher levels. I was hypogonadal, switched to this diet and my balls came screaming back with vengeance. Now my T levels are high as F**K and it is the best I have ever felt in my life. I get so much more attention from females too. My doc told me that higher T levels release more pheremones, and make females more attracted to you.
