Impact of evolution on human thought. Testosterone, Детальна інформація

On the contrary recent results from the Telecom Study showed that decreased testosterone levels were associated with increased cardiovascular risk factors in otherwise healthy men.

Eugene Shippen and William Fryer, in their book “Testosterone syndrome,” agree with the opinion that low level of testosterone are more associated with increased cardiovascular risk factors, rather than all the way around.

“The fundamental fact is this: a clear and ever-increasing majority of medical studies report an association between high testosterone and low cardiovascular disease in men. This is not a coincidental association, since when testosterone is diminished well-accepted risk factors increase, and when testosterone is administered in appropriate doses most of the major risk factors for heart disease diminish. Moreover, in the majority of patients, symptoms and objective EKG measurements improve. These studies are confirming the results I have been getting with patients for years. Men prosper health wise and live longer when their testosterone levels are normal. Heart problems, in particular, are more easily controlled (The Testosterone Syndromes, pp. 81).”

With growing old, men begin experiencing erective problems and losing sexual interest. These problems are caused by diminishment in testosterone level. Facts reveal that men who are taking testosterone, in any form, experience surge of sexual interest, and overall enhancement in physical strength. Eugene Shippen, and William Fryer, in their book “The Testosterone Syndrome,” relate diminishing sexual interest to a sign of future heart disease and diabetes, conditions common in the male menopause (“The Testosterone Syndrome,” pp. 59)

At the end of this research, I would like to notice and bring example of the fact that majority of scientific world hold opinion that artificial testosterone if correctly applied can bring much of good to the human kind, especially to elderly.

“Standford R. is seventy-four years old now, but he has had heart problems since the early 1970s. It did not make life easy for him. He is an athletic man who likes to hunt, fish on the river, and walk in the woods. By the time Standford together with his chest pains, got into the 1980s, it was time for a quintuple bypass. The chest pains started up again in a few years later. His chest pains went away, his energy returned and when he is not walking over the hills and fields and hunting in the woods, Standford makes love. Sometimes twice a day (“The Testosterone syndrome,” pp79).

Conclusion

As can be concluded from all researches discussed above change in testosterone level triggers changes in behavioral pattern, and environmental change followed by change in behavioral pattern triggers change in testosterone level.

The arguments in scientific world regarding testosterone and their role in human anatomy are not over yet. The subject is hard to explore, because experiments that has to be done in order to find right answers are not considered to be ethical on humans. The scientific world has no choice, but to use random historical facts to come to the answers. However, the fact the testosterone play a huge role in human development and behavior is not argued by any more.
