    A recent meta-analysis found a 40-year decline in sperm count in a large sample of men across North America, Europe, Australia and New Zealand, NBC News reported.

    Researchers from the Hebrew University in Jerusalem and Icahn School of Medicine in New York reviewed 185 studies from 1973 to 2011, and observed a 52 percent decline in sperm concentration and a 59 percent decline in total sperm count.

    "For couples who are trying to conceive, this is a very severe problem and it's difficult psychologically, but in the big scheme of things, this is also a major public health issue," said Dr. Shanna Swan, an author of the study and professor of environmental medicine at the Icahn School of Medicine.

    The paper doesn’t give reasons for the decline and cause-and-effect is unclear. But Dr. Joseph Alukal, a urologist and director of male reproductive health at NYU Langone Health, recommends that men can increase their count with a healthy diet, exercise, by not smoking and getting sleep.
