Chinese scientists have found alarming results by examining the sperm of men who want to become fathers. Approach According to the study in which 34 thousand men participated; It turned out that air pollution affects sperm negatively.
THE DECREASE CONTINUES SINCE THE 1970S
Studies conducted in Europe, North America and Australia have found that sperm counts and quality have decreased since the 1970s. The scientists suggested that in areas with higher pollution levels, sperm count and quality dropped to negligible levels.
The researchers used a World Health Organization-approved method to analyze the quality of sperm from men.
CONNECTED WITH AIR POLLUTION AND SPERM QUALITY
Official air quality records were used to check the air pollution levels they experienced up to 90 days ago. The men in the study were divided into four groups based on how polluted their areas were. Men living in areas with the highest air pollution had low sperm counts, almost half what they should have been. Experts said this is more evidence of a potential link between pollution and low-quality sperm.
