UNITED NEWS INTERNATIONAL (UNI) — A new study is sounding the alarm on what may be a male fertility crisis.
Scientists behind the research say sperm counts in developed nations have dropped by more than half in recent decades and if the trend isn’t reversed, the human race could be at risk.
An international team of scientists recently analyzed dozens of past studies including data from more than 40,000 men.
They found that between 1973 and 2011, total sperm counts among men from North America, Europe and Australia declined by 59 percent. Sperm concentration also fell by 52 percent.
The decline is most apparent in Western countries. Recent studies have linked the problem to chemical and pesticide exposure as well as to lifestyle factors like stress and obesity and even wearing too tight of underwear.
The new study published in the journal “Human Reproduction Update” calls for urgent research to better understand and reverse the trend.
