Benefits of testosterone replacement in men with low T, who present with ED, low libido, fatigue, insomnia, weight gain, and brain fog, can lead to a more productive and effecient workforce. 

Men with low T often present with erectile dysfunction, low energy and decreased mental sharpness.  Treatment can produce stronger soldiers by restoring normal physical stamina, muscle mass and recovery time.  Replacing testosterone, when low, can improve training, ability to carry gear and overall resilience. 

I have treated many active-duty military personnel at a nearby military installation who experienced prolonged physical and psychological stress associated with deployment. Some presented with symptoms including fatigue, reduced libido, erectile dysfunction, and depressed mood.  In appropriately evaluated patients, laboratory testing confirmed testosterone deficiency.

Chronic stress and sleep disruption may contribute suppression of the hypothalamic-pituitary-gonadal axis, although testosterone deficiency is multifactorial.  Cortisol significantly high or low due to the extreme stress of being shot, eating MRE's, away from family in a foreign country, who were diagnosed with PTSD and given antidepressants and sleeping pills can often improve when hypogonadism was confirmed. They actually had low testosterone, from cortisol stealing testosterone for flight or fight mode, with markedly improved energy, mood, sexual function and overall health with testosterone replacement.
