Is it all genetic, or does lifestyle/training have any effect. I read one study in Finland that found an increase in testosterone after 2 years of training (on Olympic weightlifters), yet I’ve heard people say that doctors say that there isn’t much that can be done about changing one’s testosterone levels. What’s the story?
There are definite advantages to having higher testosterone levels. So how come there isn’t much research on what causes variations in testosterone levels and how to improve them. It seems that you can’t do anything about it until your levels reach 300 ng/dL or below. Somehow, you suffer through life with lower testosterone, meaning you are less decisive, less masculine-looking, etc, and can’t do much about it.
