Study finds age alone may not cause testosterone to fall

A new study at the University of Sydney, Australia, suggests testosterone levels don’t necessarily drop with age, but it’s more likely among older men with declining general health.
Bucking prior research indicating age-related testosterone deficiency contributes to deteriorating health, fatigue and libido loss, Australian researchers found that blood testosterone amounts didn’t fall in older men with optimal health.
The data, gathered as part of the Healthy Man Study, is scheduled to be presented Tuesday at the Endocrine Society’s annual meeting in Boston.
