Psychological Stress Affects Male Fertility

the MPR take:

While perceived stress and stressful life events may impact semen quality, it seems that work-related stress does not. From 2005–2008, 193 men between the ages of 38–49 were studied on the relationship between stress measures like job strain, perceived stress, and stressful life events and outcome measures of sperm concentration, percentage of motile sperm, and percentage of morphologically normal sperm. The researchers found that perceived stress was inversely related to sperm concentration and that men who experienced two or more stressful life events in the past year had a lower percentage of motile sperm and a lower percentage of morphologically normal sperm. While unemployment was associated with reduced semen quality, job strain was not.

Psychological Stress Affects Male Fertility

Psychological stress may degrade sperm quality and sperm fertility, according to a study published today in the journal of Fertility and Sterility. “Men who feel stressed are more likely to have lower concentrations of sperm in their ejaculate, and the sperm they have are more likely to be misshapen or have impaired motility,” said researcher Pam Factor-Litvak, an epidemiologist at Columbia's Mailman School of Public Health, in a statement.
