Testosterone is a pivotal sex hormone that performs multiple functions throughout the human male lifecycle. Apart from being a major determinant of male sexuality, testosterone has now emerged as an indicator of a primary symptom of old age among men, i.e., loss of muscle mass. If the results of the latest study on the impact of testosterone on older men are to be believed, the higher testosterone levels among older men help in retaining their muscle mass and body strength.
While the causes of lean body mass loss are traditionally attributed to lack of dietary discipline and physical exercise, the hormonal imbalances were always suspected to play an important role in the events leading up to loss of strength in the muscles.
Aging men tend to lose more muscle mass and strength in arms and legs than women. This clearly implies that the sex hormone in men discreetly plays a role in determining the strength and muscle mass among older men.
A recent study involving 1,183 men aged 65 and older concluded that the amount of testosterone in the body determines the quantum of loss of muscle strength and mass as men grow older. The results of the study were published in The Journal of Clinical Endocrinology and Metabolism.
While we have grown up with the belief that loss of muscle strength with age is natural and should be accepted without questioning the rationale, the new findings will certainly open up new vistas for the researchers to further delve into the treatment aspect of weakened muscle strength in seniors. Perhaps, the next step should be to manufacture and test new medicines comprising testosterone supplements for their efficacy in preventing loss of muscle mass. Although hormone replacement therapy is not a foolproof treatment option, yet the latest studies have brought in a ray of hope for older men suffering from stability issues and limb weakness.
