Honey I shrunk the twins

I would venture to say that its probably from poorer diets than generation to generation test leak.

Obesity is a cause of or perhaps correlation of lower test.  The amount of fatties have been growing as a percentage of the population.

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.

Is that even a statistically significant difference?
 
well there is a lot of weird stuff going on. About a year ago there was an article which said ----many common plastics used for food storage, because of their molecular structure, can sometimes set off the estrogen receptors in men. Also read that because of birth control pills and all, you can actually measure estrogen in streams and runoff It is all a bit scarry. Maybe AS isn't so bad after all

i also find it strange that testosterone is said to contribute to agressive tendencies,but in fact its been shown that low test levels can have the same effect.

I also read that 'roid rage is simply an exaggeration of one's personality. So if you juice, whatever your personality is will magnify.

I'd better not consider roids.

Of course testosterone can cause increased aggressive behaviour.  What do you think the ratio of men to women is who get into fist-fights, etc.?  Of course much more men, due to higher T-levels.  It is the same with animals, like lions and elephants, etc., the males fight like crazy when breeding season hits and their t-levels are elevated. If you castrate a healthy adult male, his behaviour will change dramatically, less aggressive towards other males, and almost no sexual drive towards anything!
That is one reason why I don't want to mess with steroids, I am 28 years old, already a very aggressive and horny person, the last thing I need is more test, even if it helped my muscles grow, it effects alot more than just muscles.
I am not saying that if you take steroids you will turn into a raving lunatic, just that steroids (basically all hormones) absolutely affect the nervous system and that can translate into behavioural changes.

edit- BTW, I am not anti-steroids, there are valid reasons to use them, just as there are valid reasons not to use them.

theres a big difference between dominant behavior and plain old aggressive tendancies,if it was the case that everyone with high levels of test became agressive then there'd be alot more murders,when you consider that most serious people on gear are running between 500mg-4 grams per week,which is well over 10x the norm.however im willing to accept that behavioral changes do occur,of course.test is only part of the equation when talking about behavior changes,dht,seratonin and other chemicals play a vital roll in these changes,it comes down to,each person is effected differently.
 
plus if the study bob posted is anything to go by then everone is becoming less aggressive,which is a good thing.

You are right Icars, there are are far more variables than just test. And it does come down to a person's psyche ultimately. A mentally stable person who takes a ton of male hormones may have some increased aggressive feelings, but will probably be fine. Someone however with mental problems and a short temper is a likely candidate for 'roid rage'.

I just wanted to point out that a link between hormones and mood/behaviour has been known for a long time, and is nothing new or weird. Anyone experimenting with artificial hormones like steroids should be aware of this. Testosterone related steroids affect the entire system, not just the skeletal-muscular system, hence side-effects on skin, sex organs, brain and nervous system, cardio-vascular system, etc. If science could come up with a drug that only affected the skeletal-muscular system, without affecting the rest of your body, I would be on board, but as of now this looks impossible.

yeah there are some that ive looked into that have some of the properties you mentioned ie,certain compounds used are reduced to a far less potent androgen(which is the main culprit)which in turn has less effect on the skin,scalp and prostate etc while maintaining a large effect on muscle tissue,unfortunatley it has the same effect on your hpta,which is total shut down.
