testosteronewarfareMale-male competition can shape some behavioral or morphological traits of males. Here we investigate if this competition could play a role in the persistence of the polymorphism of handedness in human populations. A negative frequency-dependent selection mechanism has been hypothesized...

These findings are discussed in light of Geschwind's hypothesis of a testosterone-mediated association within families between left-handedness, immune disorders, and dyslexia. 展开 关键词: Monte Carlo simulation adsorption potential barriers DOI: 10.1001/archneur.1987.00520180054016 被引量: 260 ...
Another very interesting observation is that certain immune deficiencies are more prevalent among left-handers. In some of these cases, elevated testosterone levels in the fetus is known to be the cause. The salient point about testosterone is that it's always found in higher levels among male f...

Because males are overrepresented among lefties, some scientists propose exposure totestosterone in the wombmay affect handedness. Subtle differences Lefties may have a higher propensity to certain health problems, but they are also overrepresented amongst geniuses, Coren said. ...
left handed baby. This can explain why more men than women are left handed. Testosterone is the male sex hormone. However, studies have since come out debunking this theory; yet, it still caries prevalence because there is an increased amount of left handedness when there is a higher amount...
The testes are located outside the male body. They stay protected in a sac called the scrotum, which is located between the base of the penis and the anus. A man has a pair of testes consisting of testosterone, Sertoli or nurse cells, and Leydig cells. It is possible that the testes...
