Sperm counts in Western countries have decreased by half in recent years, suggesting a continuing and significant decline in male reproductive health, a new evidence review reports. “We found that sperm counts and concentrations have declined significantly and are continuing to decline in men from Western countries,” said Shanna Swan, PhD, professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai. “We don’t have a lot of data in men from non-Western countries, so we can’t draw conclusions about that part of the world,” add Dr. Swan. The continued decline raises concerns about male fertility, and also male health in general. “We are worried about these low sperm counts not only because people have trouble conceiving, but also because men with low sperm counts go on to have higher all-cause mortality.”
