Additionally, our "normal" levels don't seem to be a reliable measurement. Men today are less hairy, have more cases of gynecomastia etc.. than 40 years ago because testosterone levels are dropping with each generation and there are countless amounts of environmental estrogens that we're exposed to daily. Whether it's the estrogen pumped chickens to produce their breast growth so those raising them are more profitable, or the water we drink which is contaminated with all the birth control women take, or the produce we eat which is sprayed with pesticides, or the plastics we use every day- we can't escape it. There's actually a study out that shows how testosterone levels in American men has dropped 20 % in 20 years. The study ranged from something like 1980 -2000. Meaning a 60 yo man in 2000 has, on average, 20% less testosterone than a 60 yo man from 1980. And who's to say how long this has been going on? birth control was introduced in 1950, I believe, so has this decrease been going on for this long? If so, that would mean our "normal" range for testosterone is actually WAY off. Maybe our testosterone levels should actually be much higher, but the average level when the normal testosterone range was measured and created was already altered by this testosterone decline. Who's to say the average man 100 years ago, before all the environmental estrogen exposure didn't have 40 % higher testosterone than the average man today- but just because the average man today has this lowered level, doesn't mean it's actually normal. If we take the average of 95% or so of the population to determine the normal level, but 100 % of the population's testosterone has been decreasing since the introduction of environmental estrogens, that 95% considered normal, is actually lower than what it would be, say 100 years ago. So our "normal" levels are actually based on skewed results-chemically altered men. So who's to say that normal shouldn't be 40% (or even more) higher than the scale reads today. Certainly this would explain why so many men feel shitty toward the lower end or the normal range, but feel much better at the higher end. Maybe the higher end 800-11000 is what the average man had 100 years ago. and the results we see today are only the result of decline due to all the environmental estrogens we're exposed to every day over the past how-many-ever years.
Low testosterone in men today is probably real and I beleive it. The artifical hormones in livestock and crops may not help, could be a part of it I just dont know after freezing and cooking how much it actualy affects men, and plastics in cooking and such probably dont help. The big thing is mens overall fitness, look at the amount of men over weight and dont work out. Men 40 years ago had to chop wood, mow lawns with powerless mowers, pretty much had a to work a lot harder at life then we do now, besides eating and going to the shiter everything can be done from your couch. If men were to be in shape and fit I would suspect the numbers to be much higher.
