Too much testosterone kills brain cells
September 27, 2006

WASHINGTON (Reuters) -- Too much testosterone can kill brain cells, researchers say, in a finding that may help explain why steroid abuse can cause behavior changes such as aggressiveness and suicidal tendencies.

Tests on brain cells in lab dishes showed that while a little of the male hormone is good, too much of it causes cells to self-destruct in a process similar to that seen in brain illnesses such as Alzheimer's.

"Too little testosterone is bad, too much is bad but the right amount is perfect," said Barbara Ehrlich of Yale University in Connecticut, who led the study.

Testosterone is key to the development, differentiation and growth of cells and is produced by both men and women, although men produce about 20 times more of the hormone....

Writing in the Journal of Biological Chemistry, Ehrlich and colleagues said their findings meant people should think twice about supplementing with testosterone, even if it does build muscle mass and aid recovery after exercise....

1. Anyone surprised?

[Ameritopia]

49. Yet men outperform women

on most standardized tests

[blonndee]

51. Your point? n/t

[nodehopper]

54. yeah....

and there have never been any studies about how standardized tests have demographic bias...and black people are stupider than white people because white people do better on the SATs...because standardized tests have been SHOWN to be objective criteria of INTELLIGENCE, rather than socialization into a particular style of learning.

[Atman]

2. What, no comments about macho war lord, GWB, yet?

Talk about dead brain cells!

[nolabels]

39. Considering he probably was only operating on two in the first place......

it kind of makes the situation kind of touch and go at best :shrug:

4. Sophia and Athena goddess of Wisdom

they are women

15. Yes and Enki, Ganesha, Fugen Bosatsu, and Bacchus are Gods

attributed with wisdom. Was there a point, or were you just trying to be insulting to men in general?

[eppur_se_muova]

5. Thanks, we already had that figured out. nt

[hlthe2b]

6. MUST....

NOT.....


SAY.....


ANYTHING!!!!!!!!!!!














Whew, that was tough...:evilgrin:

9. I'll Say It Then...Testosterone All Around To My GOP Colleagues

It's on the House! and the Senate!

8. No shit.....

add some Black Label beer and you've got some serious mental retardation.....Water is wet, too.

[Uncle Joe]

38. Eureka! This is exactly why it was so important

according to the mass corporate media in 2000 to choose a President you would be comfortable having a beer with.:think:

[Demonaut]

10. no mention of DHEA supplements

I wonder if this can also be a problem?!

[sendero]

25. I strongly..

... doubt it, since it doesn't really do anything :)

[Megahurtz]

40. What's about DHEA supplements?

Are they bad to take?

[Demonaut]

55. my impression is that DHEA is converted to testosterone

within the body

[NOLADEM]

11. They spent money on this? What next: Is water wet?

[DuaneBidoux]

12. It still makes sex more fun.

[dweller]

17. the brain is the sexiest erogenous zone

unless it's nullified with testosterone.


imo
dp

[BlueIris]

31. And without it, it's kinda impossible to have sex, so...

I miss having testosterone. Thanks, L/O Ovral-28. FUCK HORMONAL CONTRACEPTIVES.

13. *ahem*

14. I could say something...

but I won't.

[KurtNYC]

43. "the right amount is perfect" -- this is what research money buys?

[Anakin Skywalker]

20. These Researchers Just Wasted Their Money!

They should've just asked women all over the world. :)

[Gman]

21. Duh! Classic characteristics of Republicans and freepers

in general.

[WillieDee]

22. the more hair you have, the quicker you die.

The (few) men you find in a nursing home are invariably of a slender, slight body type. The hairy biker types all die by 65.

[Mr_Spock]

23. lol

stereotype much?

[AnneD]

45. Actually...

that is a pretty good description of most Nursing Homes I've ever worked in. And the women that have a little padding do well too-but the thin little mean ones are immortal.

[pitohui]

53. uh oh

i might be a thin little mean one

[sendero]

24. Anyone who doubts this..

... should go to a bodybuilder discussion forum (yes, there are DUs just for weightlifters) and read the discourse. :)

[darkism]

26. Is that why I'm so smart? ;)

I'm the girliest guy I know, but (not to toot my own horn) I like to think I'm pretty bright. Perhaps this is why. :D

[woodsprite]

27. OMG! I know a guy at work that I've ALWAYS said that about.

Now I have proof! :evilgrin:

[leesa]

28. No shit!

[Irreverend IX]

29. It also weakens the immune system.

That's why healthier men tend to develop more characteristically masculine traits like broad shoulders and deep voices. If an adolescent boy's immune system isn't strong enough to handle a high testosterone load, his endocrine system will recognize that and testosterone production will be less. But there are lots of hormones that can harm you in large concentrations. Estrogen can contribute to circulatory problems and increased risk of breast cancer if too much is administered.

Also, women shouldn't bash testosterone too much -- females secrete it as well, and it plays a key role in female sexual pleasure. Low testosterone for a woman means a lot fewer orgasms.

[Trajan]

30. When you cut through the cutting, adolescent commentary ...

One might realize this could be a serious issue, even if it is 'obvious' .... This is yet another message to those who might consider using steroids .... and hopefully dont ....

32. But if you're a woman, it will make you a faster runner

Length of a woman's ring finger reveals her sporting ability

28 September 2006

For an instant guide to how fast a woman can run, take a look at her hands. Women whose ring fingers are longer than their index fingers are quicker on their feet, offering a simple way of predicting who will win a race, researchers have found.

The discovery could be a boon for parents wondering whether to shell out large sums on coaching - by providing an indication of their daughter's chances of turning into a sports star.

Unlike men, most women have ring fingers that are shorter or the same length as their index fingers. Only a few have longer ring fingers.

The finding adds to evidence that the ratio between the two fingers - not the length itself but their length relative to each other - is associated with a number of different personality traits, which include sexuality, fertility, intelligence, aggressiveness and musical ability. The difference is believed to be linked to the level of the male hormone testosterone, to which the foetus is exposed in the womb. Scientists have suggested that the higher the level of testosterone, the more masculine the resulting foetus is likely to be, with its associated traits of strength, fertility and mathematical ability.

Unfortunately, while a longer ring finger is associated with some desirable traits, such as musical skill, a longer index finger is associated with others, such as intelligence, past research has shown.

46. OMG....

My ring finger is bigger than my index and I did very well in track in my younger days. Couches thought I wouldn't be good because I was short...but they would be shocked at my times. Cool:thumbsup:

[xxqqqzme]

58. my ring fingers on both hands

are longer. Des that count for dance and/or gymnastics?

[Seabiscuit]

34. So that's what happened to Ah-nold?

[zanne]

35. I KNEW IT! nt

[RaleighNCDUer]

37. When I saw this, my first thought was Richard Dawson's line in

'The Running Man' as he is verbally abusing his behemouth bodyguard --
"Whatsa matter? Steroids make you stupid?"

Some people saw this twenty years ago.

[KamaAina]

41. I knew it! "Cranial Testosterone Poisoning" is real!

I spent quite a while as the "token male" in a clinic defense movement. Sometimes the women would forget I was around, so I got to hear lots of female locker-room talk. Among this was the notion of "Cranial Testosterone Poisoning", or CTP, which they deemed to be epidemic -- and lo and behold, fifteen years later, science has at last caught up with the feminists!

[Ameritopia]

48. At least we have more than one brain cell

Just kidding ladies, don't get excited.

[Ameritopia]

42. But women love it!!!

[Pastiche423]

44. Not this woman

[Ameritopia]

47. Why not?

[ckramer]

50. In one episode of Frasier

The Crane's family and friend of five went to a ski resort for the weekend. That night, Niles was after by the beautiful sexy woman and by the handsome French speaking ski coach, but no one wanted Frasier, who apparently has more testosterone.

[pitohui]

52. what was their first clue EOM

.

[daleo]

56. Comment from the story about estrogen

Ehrlich's team tried the same thing with the "female" hormone estrogen, just to be fair.

"We were surprised, but it actually looks like estrogen is neuroprotective. If anything, there is less cell death in the presence of estrogen," she said.

[Make7]

57. Huh?
