Western Men’s Sperm Counts Are Dropping, and Scientists Don’t Know Why

Western Men’s Sperm Counts Are Dropping, and Scientists Don’t Know Why, by LiveStrong from mid 2017.

Researchers from Hebrew University-Hadassah Braun School of Public Health and Community Medicine in Jerusalem announced this week that sperm count in men residing in developed countries has dropped by a whopping 50 percent over the past 40 years. They claim this alarming trend could potentially result in a decline in male health, fertility and possibly even extinction if the trend doesn’t turn around.

“This study is an urgent wake-up call for researchers and health authorities around the world to investigate the causes of the sharp ongoing drop in sperm count,” explained study co-author Hagai Levine.

After data was collected from 185 studies looking at sperm count and concentration in men from North America, Europe, Australia and New Zealand from 1973 to 2011, researchers found that total sperm count declined by 59.3 percent and sperm concentration declined by 52.4 percent.

Data from men in South America, Asia and Africa were also examined, however, no serious decline was detected. Researchers did note that not as many studies have been conducted in these regions.

Researchers didn’t look into reasons why the drop in sperm count occurred, but noted that the phenomenon has been previously linked to factors ranging from exposure to chemicals and pesticides to lifestyle choices, including smoking, obesity and stress. They are worried that if things keep heading in this direction, the human race could be doomed.

Could it be connected to the obesity epidemic? Some new chemical in our diets perhaps?
