Men's testosterone levels declined in last 20 years

[poison]

^I was just thinking that. You cant get away from that ****. tThey put that stuff in everything! F*** soy. Thats **** is for f**s and women. They might as well change the name from soy bean to h*** bean. And I dont get it I see these hott girls with these guys that I can hardly tell their male. if you can be confused for a women at any distance then your a f**. its sickening!

:huh: Take it easy, it's just a ****ing soybean.

Dr.D...I have actually read somewhere about aggression in relation to low testosterone levels in males. I cant recall where so I will have to look.

Definitely, I agree with that Size. I'm sorry, I guess I'm not making my point very well. My accretion is really just that testosterone is correlated with aggression and that's just the way the good Lord made it! Your body is a finite system and every part must necessarily have some influence on every other part because a stable system requires constant equilibrium. Parts may operate more or less exclusively but the system is a result of the function and interaction of all those connected parts. Using a specific chemical will usually result in a very predicable response based on the nature of the chemical. This is the principle that Pharmacology is based on. In other words, any endocrine manipulation at all will have appropriate behavioral consequences, even if you are not consciencesly aware of it. It could range anywhere from obvious physical hostility to subtle passive aggression or it may be totally positive energy, but something is happening. It can be caused by high or low levels because any change in the gradient disrupts equilibrium. Progestins for example can foster a unique type of attitude characterized by whiney intolerance. Estrogens can often promote emotional instability in multiple forms. SERMs can cause a similar type of crankiness but usually even more sinister than the rest because of a combined anti-social component. If you are affected in any adverse way, the best you can do is employee a healthy coping mechanism for release of aggression (anything physical like sports) or take another chemical to oppose the specific symptoms of the altered testosterone level. Benzodiazepines and diuretics are sometime used with great success.

Basically, any imbalance in proper levels of sex hormones will result in sure physiochemical changes that may result in frustration, depression, anger and even aggression and mania (rage). I am not saying that one is ever entitled to use that to excuse belligerent behavior, but to say that there is no link between testosterone and aggression is just naive! It does not take a scientist to realize this. If you belong to a gym or have a girlfriend on her period or have a kid going through puberty, you already know this little fact of life without me trying to expalin it!

Very interesting.......Thanks Dr. D Now I have the upper hand on all men in the universe!!!!!!! :bruce2: They cant fool me anymore!!!! :aargh:

 

[DR.D]

Haha, yes F&F, you are indeed the gait keeper! I won't ever deny you that.

The only logic I could see with that is there is a known correlation with high dopamine levels, and high testosterone levels. Smoking (nicotine) causes a spike in dopamine... Although I'm not too sure about this because I thought it was Test that caused high dopamine :think:

A few years ago I read sonething about nicotine raising
test-levels by increasing Gonadotrophin Releasing Hormone.

As for the enviromental influences, it´s more likely to be caused by multiple ways, such as soy-bean and unsatuarated trans-fat acids, which will in return produce fat-deposits which will quench the HPT action, by realisnig estrogens and damaging cytokines, less smoking, less "pure" man jobs (being with other men increases test-levels:good: ) and
a declining smoking-habitute among people in conjunction with overweightm, mabybe even bad sleep-patterns.

Also, the married male with kids, has a strong decline in testosterone to stay with the family and not chasing other females.:run: .

As for enviromental issues, I don´t believe in evolution so much, we develop the way, that nature dictates us to be,
we don´t adapt like rabbits or rats by a high reproduction-rate
and short life-span.

There are still "palaeonthologic" beings in the oceans, so why didn´t they change, or adapt? -because they just happen to be the way the are and as such, as a complete product of hazard.

I think Darwin is overstated, too, cause, if it´s just hazard, there´s only littel survival of the fittest, just a being together, with the only choice to play ot your genetic code.
There may be adations and wevolution but that´s rather will powered or too slow to happen at such a short time.

So in today´s world, I see not an adation, it´s a degeneration, because we are not challanged the way we were before challanged with a more or less "pure" natural enviroment.Plus, we ´re negativley challanged by unheathy food and habits and psychological illnesses, because most of the civilized population has completely lost a feeling to their own body and its needs, or are forced into a negative loop-hole, that needs to be addressed to the "different" peolpe being miscalled buklemic and sick because they have a BMI of 20, and energy to waste, which is then again calles ADS, to get some products sold.

BZT wasn´t test in men associated with more compliance and
"coolness" so-to-say, and rather the huge amounts of estrogens produced, that makes the equilibrium shift to a more aggressive behaviour... like females being more aggressive and impulsiv than males? I think it was in Havard, where it was done, lately, but only with adolescece boys and girls recieving hormones.

Forgot about this thread. Obviously, with hormonal changes mood does change. But then why are there countless conclusions that aggression is not correlated to androgen level? Is it because it is difficult to measure or induce in a clinical setting or if the person knows they are being watched? Here are a few to show you what I mean:

The effects of supraphysiological doses of testosterone on angry behavior in healthy eugonadal men--a clinical research center study

Anecdotal reports of "roid rage" and violent crimes by androgenic steroid users have brought attention to the relationship between anabolic steroid use and angry outbursts. However, testosterone effects on human aggression remain controversial. Previous studies have been criticized because of the low androgen doses, lack of placebo control or blinding, and inclusion of competitive athletes and those with preexisting psychopathology. To overcome these pitfalls, we used a double-blind, placebo-controlled design, excluded competitive athletes and those with psychiatric disorders, and used 600 mg testosterone enanthate (TE)/week. Forty-three eugonadal men, 19-40 yr, were randomized to 1 of 4 groups: Group I, placebo, no exercise; Group II, TE, no exercise; Group III, placebo, exercise; Group IV, TE plus exercise. Exercise consisted of thrice weekly strength training sessions. The Multi-Dimensional Anger Inventory (MAI), which includes 5 different dimensions of anger (inward anger, outward anger, anger arousal, hostile outlook, and anger eliciting situations), and a Mood Inventory (MI), which includes items related to mood and behavior, were administered to subjects before, during, and after the 10 week intervention. The subject's significant other (spouse, live-in partner, or parent) also answered the same questions about the subject's mood and behavior (Observer Mood Inventory, OMI). No differences were observed between exercising and nonexercising and between placebo and TE treated subjects for any of the 5 subdomains of MAI. Overall there were no significant changes in MI or OMI during the treatment period in any group. Conclusion: Supraphysiological doses of testosterone, when administered to normal men in a controlled setting, do not increase angry behavior. These data do not exclude the possibility that still higher doses of multiple steroids might provoke angry behavior in men with preexisting psychopathology.

The prospects of wider application of testosterone (T) in novel indications such as male contraception have prompted renewed interest in the investigation of nonreproductive actions and safety of androgens. This study investigated potential changes in mood and behavior in response to elevations in circulating T concentrations produced by the new long-acting preparation, T undecanoate (TU).

Twenty-eight eugonadal men were randomized into one of two treatment groups: A1) active, receiving 1000 mg TU im followed by A2) washout, followed by A3) placebo, receiving 4 ml castor oil im; B1) placebo, 4 ml castor oil im; B2) washout followed by B3) active, receiving 1000 mg TU im. Mood, self- and partner-reported physical and verbal aggression, anger, hostility, irritability, assertiveness, self-esteem, and sexual function were assessed.

A single injection of 1000 mg TU im increased plasma T concentrations from 20.7 ± 1.5 to 37.5 ± 2.2 nmol/liter at wk 1 and 31.6 ± 1.5 nmol/liter at wk 2, and estradiol from 74.0 ± 4.9 to 120.4 ± 10.7 pmol/liter at wk 1, and 100.0 ± 6.3 pmol/liter at wk 2.

The T increment was associated with detectable but minor mood changes. Increased circulating T was associated with significant increases in anger-hostility from baseline (mean score = 7.48) to wk 2 (mean score = 10.71) accompanied by an overall reduction in fatigue-inertia (treatment = 6.21 vs. placebo = 7.84). TU treatment did not increase aggressive behavior or induce any changes in nonaggressive or sexual behavior. Changes in estradiol were not associated with any behavioral alterations.

Our results suggest that exogenous TU-induced elevation of circulating T, to the range likely to be used in hormonal male contraception, has limited psychological effects. Future research should investigate the implications of these minor mood changes.

The Male Menopause and Mood: Testosterone Decline and Depression in the Aging Male—Is There a Link?
Howard C. Margolese, MD, CM

The objective of this study was to review the literature on the hormonal changes that occur in aging males in order to determine if testosterone declines in relation to depressed mood and if testosterone might prove useful in treatment of depression. Pertinent articles were identified through a MEDLINE search from 1966 to 1999 and by careful review of the bibliographies of articles most relevant to the topic. There is a moderate decline of total testosterone and more significant decline of bioavailable testosterone in aging males. Elderly males who are depressed appear to have the lowest testosterone levels. In eugonadal males, testosterone replacement does not have a significant effect on mood; in hypogonadal males, some studies show an effect whereas others do not. In several small studies of depressed hypogonadal males, testosterone was effective in alleviating depression. Major side effects of testosterone include increased hematocrit and potential effects on the prostate and lipid metabolism. Testosterone replacement as primary or adjuvant treatment of depression may prove useful in elderly, hypogonadal males who fail to respond to conventional antidepressants. Further studies are needed to confirm these initial impressions. (J Geriatr Psychiatry Neurol 2000; 13:93-101).

I do see lots of studies in hypogonadal males reporting an increase in aggression when administered T, but fewer with eugonodal. Attached something I found interesting with a decent introduction to some of the research.

i dunno if anyone has mentioned it but what about sport supplementation. in the last few yrs with andro's ph's and what not that werent around 20 yrs ago could have a impact if taken at one time in the past no?
