This article was very interesting:


---------------------------------
FRIDAY, Oct. 27 (HealthDay News) -- The testosterone-fueled American male may be losing his punch.

Over the past two decades, levels of the sex hormone in U.S. men have been falling steadily, a new study finds.

For example, average total testosterone levels in men aged 65 to 69 fell from 503 nanograms/decileter (ng/dL) in 1988 to 423 ng/dL in 2003.

The reasons for this trend are unclear, said researchers at the New England Research Institutes in Waterdown, Mass. They noted that neither aging nor certain other health factors, such as smoking or obesity, can fully explain the decline.

"Male serum testosterone levels appear to vary by generation, even after age is taken into account," study lead author Thomas G. Travison said in a prepared statement.

Testosterone is the primary male sex hormone and plays an important role in maintaining bone and muscle mass. Low testosterone levels have been linked to health problems, including lowered libido and diabetes.

It's normal for men's testosterone levels to peak in their late 20s and then start to gradually decline, experts say. But this study found that overall testosterone levels are lower than they were 20 years ago.

"In 1988, men who were 50 years and older had higher serum testosterone concentrations than did comparable 50-year-old men in 1996. This suggests that some factor other than age may be contributing to the observed declines in testosterone over time," Travison said.

He and his colleagues analyzed blood samples -- along with health and other information -- from about 1,500 men in the greater Boston area who took part in the Massachusetts Male Aging Study. That study collected data in 1987-89, 1995-97, and 2002-04.

"This analysis deals with men who were born between 1915 and 1945, but our baseline data were not obtained until the late 1980s, when the elder subjects were about 70 years old, and the youngest about 45," Travison said.

"Events occurring in earlier decades could certainly help explain our results, if their effects persisted into recent years," he noted.
------------------------------------------------


So my question is, is this a good thing or a bad thing, considering testosterone also affects how one acts in an aggressive or "fighting" manner. Are human males doomed to become, well, wimps? Or does this leave the path open for men (and to an extent, women!) to become more rational, thinking people who step back from situations where otherwise they would just charge in fists up?

One city isn't necessarily representative.

What's the average in other age brackets?

What's the margin for error in this test? A recorded change of only a couple of percentage points may not be statistically significant.

I agree with Reprobate. Maybe there is something that is affecting hormone levels in men around the Boston area. They need to study a broader population to draw any conclusions on a large population such as US males. They could say testosterone levels in Boston area males of a certain age are declining, but that is really all this study has shown.

Maybe I should tell my son to move out of the Boston area before it's too late! He's my only son and I'd like him to stay that way.

Heh.

I wonder how much of that is due to the current trend of the media emasculating men?

That is an excellent point.

If you were doing a study on crime in the US, you would not focus on just Newark, NJ. Similarly, you would not do a study on Syphilus in Baltimore, MD. It is--or was--the Syphilus capital of the world. Perhaps Boston, MA, uses poor water purification methods? Who knows? But, you need to look further than Boston to determine the delcine of male testosterone levels.

I would attribute it to the general laziness and disinclination of Americans to get off their asses and exercise. Are men in Boston unusually obese as well?


A bit off the subject, but your question reminds me of a book I once read: Malcolm Gladwell's Tipping Point. It was a great read.

A likely cause is "xenoestrogens" or "foreign estrogens," and those are not good for humans, or the planet. Aside from lowering testosterone, they also lower the sperm count, compromise the immune system, lower fertility, and affect the anatomy of all sorts of non-human animals, AND they often promote or cause cancer (as in "pretty pink ribbons and run-for-the-cure" type cancers).

One of the causes is food stored or cooked in plastic-where the xenoestrogens are absorbed from the plastic. Another major cause is the hormones (which are a form of xenoestrogen) used by ranchers to fatten animals and speed up their maturity. When you ingest the meat you also ingest the hormones.

Progesterone (in the correct dosage) is the precursor to estrogen production in women and testosterone production in men.

It appears that we must bid farewell to the generation of good wholesome air polluting heart crunching a mile to the gallon automobiles and the heart attack inducing thick texas steaks and greet the new age of extra-metrosexual reality + makeover shows.

Queer Eye for the queer guy anyone?

I just read the article you posted. Interesting, since haven't we all heard the argument before that when women rule the world, all will be well.

I'm not convinced.

Women can be more vicious than men if their children are threatened. As if suddenly, womankind as a whole, will be unable to resist the lure of powerover, and maintain an egalitarian ideal.
I'd be the first power hungry bitch with a lesbian harem.

Women ruling the world?

But as I stated draw your own conclusion.


I personally can't imagine living in a world without men.

In theory an egg has the potential to undergo the divisions necessary in order to give a new being, albeit identical to its mother. I have read of a species of aphids who forgo sexual reproduction altogether and reproduce by parthenogenesis, which means that the entire population is female. When times are tough they revert back to sexual reproduction and therefore increase genetic variability and chances of survival of the species. Males serve the only purpose of providing the genetic variability.

In response to the original post regarding the decrease of testosterone, I don't think the article mentions if they saw an increase of estrogens in these males. When I was in university I attended a conference in which the specialist proposed that our water (here in Montreal) could contain trace amounts of female hormones which would come from all the women who take the pill. Montreal is an island, and municipal water is taken from the St-Laurent (the river surrounding Montreal), which is also the river where municipal waste goes. So what this person was saying is that female hormones were then very likely present in our tap water and therefore ingested by everyone who drank the water. Eventually this would cause feminisation in men. Now I remember thinking how many liters of water a day must a man drink in order for this to happen? I did a quick search and found nothing published on this subject, so I guess it has stayed at the hypothesis level.
I agree with those who have stated that one study is not indicative of a real "problem". In order for a study like this to have any significance, it would have to be recreated by different researchers in different cities. I find that a lot of the times, the media will pay too much attention to studies like this one, just to stir up a commotion.

A world without men!? Noooooooo. I like sex with guys. I like hanging out with guys. It just wouldn't be the same.

Women can be more vicious than men..

You can just stop there!

A reading of the jucier bits of history will bear this out.

The suffragettes insisted that the world would be a better place when women had the vote.

It turned out that the number of voters was doubled. That was it! The world did not go down in flames, nor did it turn into utopia. Fancy that!

As to the original post -- our food and water have become increasingly tainted with thousands of chemicals, usually in trace amounts. It's anyones' guess what the effects are.

I find it difficult to imagine how they could ever sort out what causes what in whom.

Another biological "urban legend." Doesn't even make vague biological sense, similar to the legend that blondes will go "extinct" in a couple centuries. Probably used to get people riled up believing the endtimes are somehow at hand, or some global unified race will exist, or whatever.
