My original post had a link to another site that had a nci study implicating overwork and its association with hypogonadism. The moderators, per rules on this site, removed the link. I simply brought this up because I had never really heard this before....I knew overwork could lead to TEMPORARY or accute reduction in T production, but I had never seen any study indicating long term T reduction.
Just thought this was interesting.
Note: I also think that "normal" levels really differ for different people. Someone who is at 500 for example, might really be at his normal level. However, when you add in weight training and additional muscle mass accumulated from that, I really am curious about whether or not higher levels of muscle actually REQUIRE higher levels of T in order to "feel right". In other words, and individual who is at 500 before any training, might still be at 500 after years of training, but the additional physical workout it took to attain any increase in muscle might not be enough to sustain "normal" feel.
I know many "natural" bodybuilders who all seem to suffer from low T. They all carry pretty good muscle mass (not steroid like mass, but still admirable)and train very hard...but they all are simply drained all the time and don't seem to be enthused about anything. Now, this is not everyone, but I've seen it more often than not.
