Could exposure to chemicals be impairing our ability reproduce as a species
Researchers from a study done at Hebrew University-Hadassah Braun School of Public Health and Community Medicine in Jerusalem announced last week that sperm counts in men from America, Europe, Australia and New Zealand showed a 52.4 percent decline in sperm concentration and a 59.3 percent decline in total sperm count among North American, European, Australian and New Zealand men. And the rate of decline is not slowing.
This analysis did not look into reasons for the decline, but noted that falling sperm counts have previously been linked to various factors such as exposure to certain chemicals and pesticides, smoking, stress and obesity.
No significant decline was seen in South America, Asia and Africa, but researchers noted that far fewer studies have been done in these regions.
