Stress has many negative health consequences, including lowering testosterone levels and impairing spermatogenesis.
Although every person experiences emotional or physical stress periodically, it’s the prolonged periods that are more detrimental.
The body’s main stress hormone is called ‘cortisol’. It falls under the hormone class ‘glucocorticoid’. Cortisol is produced in the adrenal glands.
A study by Nassef et al. (2018)1 found that stress induced in Wistar rats lowered testosterone levels.
Arun et al. (2016)2 found that stress in rats significantly reduced testosterone levels as well as a particular testicular protein. The total weight of the rat's testes was significantly reduced too.
A study by Daly et al. (2005)3 proved a link between lower testosterone levels and elevated cortisol levels in humans post-endurance exercise.
During an educational course, Freuz et al. (1972)4 found that young men’s testosterone levels were significantly lower “during the early, stressful part of the course”.
Aakvaag et al. (1978)5 found that the increased cortisol levels of 8 young men through prolonged physical and psychological stress negatively impacted on their testosterone levels. Their levels dropped on average from 560 ng/dL to 90 ng/dL.
