Testosterone function in the body

How might behaviors affect hormones? The birdsong example demonstrates how hormones can affect behavior, but as noted, the reciprocal relation also occurs; that is, behavior can affect hormone concentrations. For example, the sight of a territorial intruder may elevate blood testosterone concentrations in resident male birds and thereby stimulate singing or fighting behavior. Similarly, male mice or rhesus monkeys that lose a fight decrease circulating testosterone concentrations for several days or even weeks afterward. Comparable results have also been reported in humans. Testosterone concentrations are affected not only in humans involved in physical combat, but also in those involved in simulated battles. For example, testosterone concentrations were elevated in winners and reduced in losers of regional chess tournaments.

Among the 493 men with AAMI (mean age, years [SD, ]; mean baseline testosterone, 234 ng/dL [SD, ]), 247 were assigned to receive testosterone and 246 to receive placebo. Of these groups, 247 men in the testosterone group and 245 men in the placebo completed the memory study. There was no significant mean change from baseline to 6 and 12 months in delayed paragraph recall score among men with AAMI in the testosterone and placebo groups (adjusted estimated difference, - [95% CI, - to ]; P = .88). Mean scores for delayed paragraph recall were at baseline, at 6 months, and at 12 months in the testosterone group and at baseline, at 6 months, and at 12 months in the placebo group. Testosterone was also not associated with significant differences in visual memory (- [95% CI, - to ]; P = .24), executive function (- [95% CI, - to ]; P = .14), or spatial ability (- [95% CI, - to ]; P = .89).

As we learn more about how testosterone affects women, the more we will discover how it can either benefit or hinder women in their fitness goals. Testosterone is important to female metabolic, sexual, and muscular function. And just like with men, it is important for women to have a healthy hormone balance. You don’t want too much or too little of any hormone in order to make your fitness goals. Since testosterone is not the primary hormone for women, we will have a lesser concentration than men, but there is a level that is still considered normal for us. As long as we are at this level in the body, we will remain healthy and fit.
