What Some Research Shows About Stress and Low T. Over the years, some studies have suggested that the stress hormone cortisol and the sex hormone testosterone work against each other. This has led to the theory that stress may cause infertility and loss of libido in men by inhibiting testosterone.
Stress causes the release of a hormone called cortisol. Giving rats daily injections of corticosterone (rat cortisol) for several weeks kills certain brain cells. Stressing the rats each day for the same amount of time has an identical effect. Cortisol has been shown to damage and kill cells in the hippocampus (the brain area responsible for your episodic memory) and there is robust evidence that chronic stress causes premature brain aging.
