As one read the recent study on this topic by The University of Western Australia that has been published in American Journal of Physiology: Heart and Circulatory Physiology, there were a couple of questions:
A. What attributes of youth did the study measure? Ageing for men, as regular readers would know, has implications. In fact the ageing male symptoms (AMS) questionnaire evaluates males ageing with seventeen questions across three broad categories, psychological, somatic and sexual.
B. Why is the other option, 'testosterone treatment'? Or specifically testosterone supplementation, while more natural ways of increasing testosterone exist, and have clinical evidence.
The answer to the first part is that the parameters used to define 'staying young' were, "fitness, body composition and strength." This covers the somatic part of the AMS, but the experience of ageing is more complex. Our experience of anxiety and stress, is so different after the 30s compared to what it was in the 20s. There are the sleep challenges, the question of burnout (mid-life crisis, you said?) and of course the decline in libido and sexual function. So yes, as far as the study's definition goes, there is little point arguing with the results. In any case, all of us here at Misters are strong advocates of exercise along with everything else you do to fight various signs of ageing.
The second point, comparing it against testosterone supplementation, is a more in-principle one. There is strong prevalence for the deployment of testosterone replacement therapy (TRT) in the west, and derivatives thereof, such as supplementation, but there are natural ways, such as Misters Daily Josh, which is formulated with Tesnor(TM), that is clinically proven to boost free testosterone. Surely one of the cohorts in such studies, going forward, should be this category of option, which has evidence for boosting the natural processes that lead to greater free testosterone.
However, these are relatively small points, for the message--that men should try and get more exercise--is one that we wholeheartedly endorse.Know more about testosterone
