Psychological stress is harmful to sperm and semen quality, affecting its concentration, appearance, and ability to fertilize an egg, according to a study. It is not fully understood how stress affects semen quality. It may trigger the release of steroid hormones called glucocorticoids, which in turn could blunt levels of testosterone and sperm production. Another possibility is oxidative stress, which has been shown to affect semen quality and fertility.
"Stress has long been identified as having an influence on health. Our research suggests that men's reproductive health may also be affected by their social environment," says Teresa Janevic, PhD, the study's first author and an assistant professor at the Rutgers School of Public Health.
