The male hormone testosterone is frequently associated with aggression and, well, manliness. But testosterone has a wider role to play with moods and one that could well be implicated in depression.
It has been known for some time that depleted levels of testosterone is associated with a number of conditions. In a fairly recent study, featured in the Archives of General Psychiatry, men aged 70 and over with the lowest levels of testosterone were three times more likely to be depressed. Last month, Nicole Carrier and Mohamed Kabbaj, scientists at Florida State University, were reported to have discovered a specific brain pathway that influences the effects of testosterone on moods.
Testosterone, it appears, has a protective function against depression. Professor of psychiatry at Harvard Medical School, Harrison Pope, points out that ever since the 1940s, experiments with testosterone showed that depressive symptoms could be relieved. His own early experiment with th...

A testosterone test measures the amount of the male hormone, testosterone, in the blood.
How the test is performed
Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip....
