Sperm count in developed world has drops by 50%

LONDON: Sperm counts in men from America, Europe, Australia and New Zealand have dropped by more than 50% in less than 40 years, researchers said on Tuesday. They also said the rate of decline is not slowing. Both findings -- in a meta-analysis bringing together various studies -- pointed to a potential decline in male health and fertility. The analysis did not explore reasons for the decline, but researchers said falling sperm counts have been linked exposure to certain chemicals, smoking, stress and obesity.
