Testosterone Tumbling in American Males
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.
Having being diagnosed, and having surgery and chemotherapy for this (like Lance Armstrong et al), there is a worrying trend. 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. Too see how bad it is, there are even scientific reports of fish changing sex in estrogen rich rivers - do a google on this. This is not a subject to laugh at.
As a web-page of NYUMC suggests, Tai Chi may be of help.
Quote: Enhanced Endocrine and Immune System
One study found that tai chi was associated with increased blood levels of a number of hormones, including thyroid hormone, testosterone, and estradiol. Another study found that tai chi was associated with an increased number of T cells (cells involved in the immune response).

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.
Indeed, polycarbonate - which is in pretty much everything - is made from a chemical originally used as a synthetic estrogen, bisphenol A. Bisphenol A will leech from polycarbonate food or drink containers, especially ones cleaned with very hot water, or with bleach. (Some plastics are safer: #1 PETE, #2 HDPE are fairly safe from leaching and are easy to recycle, #4 LDPE and #5 PP are also said to be safe for food storage.)
Many other chemical pollutants are also xenoestrogens. And there's also the widespread use of hormones in animal farming, as well as medical uses which means excess amounts being urinated out and ending up in the water supply.

Are you suggesting that I'm fapping my way to femininity?
Makes sense.

The other possibility is the males' levels of testosterone are dropping because they are biologically less able to produce it than they were in the 1980s. The Testosterone level in a male goes in parallel to his level of zinc intake. If you are a male who is zinc deficient, you are going to lack testosterone too. A decline of zinc in the American food supply or a changing American diet which contains less zinc rich foods like beef is going to lower the males' average testosterone level. Low zinc levels causes anorexia in females, which also seems to have worsened since the 1980s.
What whith the ubiquity of pr0n, avaliable readily for free and without embarrassment on the Intarweb Tubes, the testosterone no longer has a chance to build up in the male body.
Interesting? You don't ejaculate testosterone, you know. I'm no specialist, but I don't see why there would be a "build up".
Toit mentions wanting to take a
I am the wife of one such "pussified" (as Toit puts it) man. My husband has diabetes and many of the usual complications that come with it, one of which is low testosterone (less than half the "normal" amount). You know what? I'm GLAD his attitude is the way it is. If anything, the reduced testosterone level has served to soften the hard shell he says he used to have. He's well aware of my feelings as well as his own, and he's not afraid to show them. He loves me deeper than words can describe, and I love him equally. He loves nature, cares about his and my health, and...well, you get the idea. I don't expect I'd find any of this in the macho type Toit is trying to rally.
The way I figure it, the average Slashdot user is getting close to that time in their lives when they feel the desire to find a mate and maybe start a family. For the group of you folks who fall in line with Toit's attitude, face this fact: After hundreds of years of you men telling us women to shut up and get in line, your type is being phased out, whether you like it or not. The world does not need your crap anymore, nor does it need the sterotypical southern belle attitude some women used to have, either. Rather, all need to move away from the extremes toward some common, middle ground where men AND women can be happy.
The terms were defined as such to resolve ambiguity back in the 19th century to better describe intersexed, homosexual, and transsexual people.
Way to "revise" history. The usage of the word gender to describe someone's personality as opposed to their biological sex was invented in the middle of the 20th century. It is technical jargon used by social scientists and psychologists. I'm really tired of seeing people "corrected" when they use gender as a synonym for sex. When the the Merriam-Webster Dictionary lists "sex" as a definition, it's good enough for me. Stop trying to impose what you were told in your Humanities electives on the rest of us.
If you can read this sig, you're too close.
No, they don't put any estrogen anywhere. Chemicals which are superficially similar to estrogen are not estrogen. If you want to make the claim that those chemicals are just as bad as estrogen, that's another issue entirely. But the claim was that they are causing estrogen to be found in everything, and its simply not true. Trying to claim plastic has anything to do with estrogen in meat and milk is ridiculous.
