Low testosterone linked to depression

Men who have low levels of testosterone have an increased risk of depression and depressive symptoms, according to a new study.
Depression can range from lasting feelings of sadness and hopelessness to losing interest in hobbies previously enjoyed. It can also incur physical symptoms, such as constantly feeling tired, sleeping badly and a loss of appetite or sex drive.
Researchers at the George Washington University set out to investigate the relationship between testosterone levels and depression.
Michael Irwig, lead researcher of the study, said: 'In an era where more and more men are being tested for "Low T" - or lower levels of testosterone - there is very little data about the men who have borderline low testosterone levels.
'We felt it important to explore the mental health of this population.'
For the study, they recruited 200 men aged between 20 and 77, with an average age of 48 years old. Each participant was referred for borderline total testosterone levels between 200 and 350 ng/dL.
The researchers collected information about the participants, including medical histories, signs and symptoms of hypogonadism (reduction or absence of hormone secretion), assessments of depressive symptoms and/or any known diagnosis of depression or use of an antidepressant.
It was found that 56 per cent of the men had depression and/or depressive symptoms. What's more, one-quarter of the participants were taking antidepressants and had high rates of obesity.
Common symptoms among these men included decreased libido, fewer morning erections, erectile dysfunction, sleep disturbances and low energy.
The researchers concluded that GPs and clinicians should check for depressive symptoms and depression in men who have been referred for low levels of testosterone
