Testosterone Levels Falling
Testosterone Levels Falling
In this article studys show that testosterone levels are falling in American men. It doesn't point to any specific reason why, but it may help explain the fairly new trend of "metro-sexuality"...
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.
The findings were published in the Journal of Clinical Endocrinology and Metabolism.

I think our inablility to socially express our masculinity is repressing it.
The empowerment of women in the workplace has led to a feminization of society. And women don't generally understand loud talking . men are not always mad when they are talking loud and yelling at each other. When women are in there they act all offended and uncomfortable when you yell at them and call them a fat ho. I blame the feminists.

At my workplace it is some of the women who are the loud agressive and verbally abusive ones. Because they are young and pretty (purposely hired that way) it is tolerated (and probably celebrated) by management. The men are gentlemen, at least in the public area, but the women act like flaming whores.millipodium wrote:I think our inablility to socially express our masculinity is repressing it.

I think lowered testosterone levels may have something to do with stress in the workplace. Corporations have become efficient at milking the lifeforce of employees, including mental, emotional, and physical. Much moreso than 20 years ago. Add to that the constant bombardment of stimuli from media, cell phones, and heavy traffic commuting and you have a decreased desire for nookie recipe.

Oh I forgot to mention. It's only MEN who can't assert themselves. They can be flaming whores, as you say, in the name of empowerment.Carl G wrote:At my workplace it is some of the women who are the loud agressive and verbally abusive ones.

Any behavior that is expressly or implicitly encouraged, especially in the workplace by management, will be enhanced.Carl G wrote: At my workplace it is some of the women who are the loud agressive and verbally abusive ones.

yes, oftentimes that is the case.Elizabeth Isabelle wrote:Any behavior that is expressly or implicitly encouraged, especially in the workplace by management, will be enhanced.Carl G wrote: At my workplace it is some of the women who are the loud agressive and verbally abusive ones.

I've done a little research on the subject and found a few factors linked to a decrease in testosterone that might be playing a big role in the average American man's lifestyle. Some of these factors include a diet low in protein and low in fat, long periods of excercise, not enough excercise, not enough sleep, long periods of drawn-out emotional stress, and excessive carb intake. When I think of the way society is headed in relation to these factors it seems to be no suprise testosterone levels are in fact dropping.
With all the low fat diets and the bad wrap red meat recieves men aren't gettin enough fat and protein needed for testosterone production. Also with more and more jobs becoming office orientated, physical activity is far lower than where it should be at. A lack of sleep due to the work schedules such as the 9-5 job which is being forced down the throats of society as the norm. Personally I don't think any human being is designed to live their lives around an alarm clock. Last but not least the long drawn-out periods of emotional stress due to the responsibilities of juggling a feminine career and a family cause the body to completely shut down all anabolic processes. If you think back in history most emotional stress was very acute and short lived, unlike the stress of todays society. With that said it seems like women just might end up winning the battle of the sexes in a way they never planned on.

I would try not to lose too much sleep over this (which could lower testosterone levels). This level is well-within normal. I've known labs to consider 280-800 ng/dl as acceptable. This means (all other factors being normal) nothing would likely be done for a patient in regards to treatment.
Diurnal serum testosterone levels in the average adult male fluctuate significantly. A near 300ng/dl difference between peak/trough (a.m./p.m.) is normal. The difference from an 80 ng/dl drop would not likely be noticed by an average adult male (other than maybe his psyche). An equal drop in the average female would be a significant concern.

As far as metro-sexuality concerns, look at the differences between male/female (average) levels. The difference between genders is enormous.

I personally think, that more than anything else, it is caused by a general feminisation of masculine minds.
A feminisation of masculine thinking will lead to:
less masculine activity generally
a lesser need to react in some violent way to changes in the physical and human environment (technology has removed a lot of the physical needs for testosterone)
thus less testosterone needs to be produced.
