Anecdotally, as an aggregate, my testosterone levels increase during phases of my life when I do those things.

I suppose I am now required to look up references to support the following statements:

1. exercise without over-training boosts testosterone (maybe some middling results here: https://link.springer.com/article/10.1007/BF00441300 ) https://www.sciencedirect.com/science/article/pii/S174360951...

2. Reducing stress increases testosterone http://psycnet.apa.org/buy/2000-13208-002

3. High fat diet increases testosterone https://www.nature.com/articles/4500825 (and probably ref 33)

4. I should have also mentioned that my lifestyle often includes less drinking during these phases https://academic.oup.com/jcem/article-abstract/74/5/957/2875...

5. That i socalize more and skip work more as well. https://link.springer.com/article/10.1007/s00441-005-0006-2

and that taken as a whole, I feel more like myself, increasing self esteem, which may itself help. https://www.sciencedirect.com/science/article/pii/S136466131...

Or you can look for pop blogs. https://www.artofmanliness.com/articles/how-to-increase-test...

But of course, I just googled around for a bit to find one-off papers. It's a good starting point if I wanted to write a research paper on it, but I really don't. I wanted to provide my own experience, and have.

Quite interesting, thanks!

Yes..they do a great deal; outside activities that get you sun (Vitamin D) and the high fat (good fats not lard) give your body the raw material to make T. Exercise boosts it as well as anything involving moderate levels of fear/stress. Along with sleep.

I live in Canada, I'm basically a Vitamin D junkie. Otherwise I get depressed during November/December.

Excellent point! I had forgotten about vitamin D as well.

Diet and exercise do wonders. Best drug by far. Every other remedy is pain management.
