Testosterone Tumbling in American Males 597

An anonymous reader writes "Yahoo is running a story about a study that concludes that testosterone levels are falling across all age groups among American men. It says 'The testosterone-fueled American male may be losing his punch'" I leave it to you all to draw your conclusions about this, but I still wonder what my hours of laptop-fu does to me.

            Michael Jackson may be a reference point. His voice never changed, he never developed secondary attributes, and his baby had to be fertilized artificially, so there was some medical intervention at work there. Plastic surgery was probably not the first elective surgery he went through. I suspect that this is the root of most of his psychological problems. That's why I tend to give the guy a pass for a lot of his weirdness--the decision would have been forced on him by his father.

      Quite probably, yes. Adipose cells make an enzyme called aromatase, which converts testosterone into estrogen for the fat cell's use. (estrogen actually makes fat more metabolically active, so it's not really a bad thing per se) This, however, has the effect of lowering free testosterone in the body as a whole. If you lose fat, your testosterone levels WILL increase.

      However, keep in mind humans are the only animal species that actually get overall, most of their testosterone from DHEA rather than free testosterone in the blood. In addition to stimulating androgen receptors directly, DHEA is also metabolized by local tissues into testosterone (and estrogen) as needed. So free testosterone is one part of the picture. Androgen receptor sensitivity and density also matter, but I'm uncertain as to what factors dynamically affect those in adults.

Bisphenol A will leech from polycarbonate food or drink containers, especially ones cleaned with very hot water, or with bleach.

There is no known cause of this cancer scientifically proved, but after getting this cancer, and speaking 'hear say' to consultants, doctors. etc. one theory is that estrogen (oestrogen), the female hormone, is being dumped into the environment from products (baby products, nappies etc.). This chemical doesn't break down in nature - so drinking water, cows milk, fish, meat... all contain this bumped chemical up that would not otherwise be there.

      When women got the vote, it was inevitable that government was going to become more powerful, more intrusive, and more "protective" (ie. more coddling), because women are hard-wired to treasure security more than uncertainty and danger.
      I am supposed to believe that the women voters in this country are to blame for our heavy handed, civil rights trampling, fear mongering, war-hawking government? That all the men voted to live dangerously and with uncertainty, and the women were all like, "No, we need a large, over powered, fascist government to protect us".

      Well that and this:
      Speaking of rap music, do you want to know why more White boys buy that crap than Black boys do? You know why rape is such a problem on college campuses? Why binge drinking is a problem among college freshmen? It's a reaction: a reaction against being pussified. And I understand it, completely. Young males are aggressive, they do fight amongst themselves, they are destructive, and all this does happen for a purpose.

      Umm...what? I'm sorry but the argument that being assertive and aggressive is an appropriate replacement for being intelligent and diplomatic does not hold water with me. You can't use Rumsfeld as an example of what people should be like until you can prove that Rumsfeld isn't a complete idiot. People fear Rumsfeld because he is irrational and has the world's most powerful military at his disposal. So many people have died unnecessarily as the direct result of this man's actions and we're supposed to be more like him?

It is because, chained by guaranteed sex to relationships they do not want, they do not have the strength to hold their principles above their libidos. Restraint is strength.

I'm 40 now, but I still remember what it was like being 15-25. Thank God that's over with! It's no fun when the presence of a nubile female gives you an erection that hurts, and lasts as long as she's nearby.

    As an individual, this whole thing is also a nonissue, because natural differences in hormone levels bewteen one man and the next are probably huge -- much bigger than the effect being claimed.

    What's really scary about this is not the effect it's having on adult males (and the rest of society), which may be positive. What's scary is:
