Mental Attitude: Stress Reduces Male Fertility

Past studies have linked stress to a number of health problems including heart disease, asthma, obesity, and depression. A new study suggests that stress can also reduce male fertility. Researchers found that men who experienced two or more stressful life events over the previous year had lower sperm quality compared with men who did not experience any stressful life events. They also found that regardless of stress, jobless men had lower semen quality than those who were employed.
