Sperm counts in men from America, Europe, Australia and New Zealand have dropped by more than 50 percent in less than 40 years according to new research released a couple of days ago.
Researchers also said the rate of decline is increasing.
The analysis did not explore the reasons for the decline in full but researchers said falling sperm counts have previously been linked to various factors such as exposure to certain chemicals, air pollution, pesticides, smoking, stress and obesity.
