NIH study analyzes data from more than 450 men attempting to conceive.

Working in a physically demanding job, having high blood pressure, and taking multiple medications are among health risks that may undermine a man’s fertility, according to a study by researchers at the National Institutes of Health and Stanford University, Stanford, California. The study is the first to examine the relationships between workplace exertion, health, and semen quality as men are trying to conceive. The results were published online in Fertility and Sterility.
