Stress Impact on Sperm Quality and Quantity
It's common knowledge that stress impacts our health, but a recent study also shines the light on the impact of stress on male fertility, specifically sperm count and the quality of the sperm produced. Researchers from Columbia University's Mailman School of Public Health along with researchers from the Rutgers School of Public Health worked on the study which was published in Fertility and Sterility.

The study included 193 men ages 38-49 from 2005-2008 during which the men were evaluated for various forms of stress including life events, workplace stress and even perceived stress. Men who experienced two or more stressful life events per year had a lower percentage of sperm motility (movement) as well as normal morphology (quality of the sperm). Interestingly, these percentages remained consistent across the study group regardless of age, health issues, or even historical fertility issues.

Other interestings findings from the study include:
  • Unemployed men had lower semen quality than those employed.
  • Workplace stress did not affect semen quality, however lower levels of testosterone were found.
It is not certain how stress affects sperm quality however the team theorizes that stress could activate oxidative stress and/or that it could cause the release of "glucocorticoids - steroid hormones that affect the metabolism of carbohydrates, fats and proteins - which could reduce testosterone levels and sperm production".
