A research that was published recently found a looming global issue — male sperm counts across the globe have declined more than 50% over the past 46 years.
According to the research that was published in the journal Human Reproduction Update, it was found that this trend was prevalent in South and Central America, Asia, and Africa. It was the same for North America, Europe, and Australia, but it may have accelerated in the 21st century.
The study took in meta-analysis from 53 countries from all seven continents and found that they all pointed to the same conclusion — sperm counts are continuing to decline globally.
“Overall, we’re seeing a significant worldwide decline in sperm counts of over 50% in the past 46 years, a decline that has accelerated in recent years,” said Professor Hagai Levine from the Hebrew University of Jerusalem’s Hadassah Braun School.
“Our findings serve as a canary in a coal mine.”
“We have a serious problem on our hands that, if not mitigated, could threaten mankind’s survival. We urgently call for global action to promote healthier environments for all species and reduce exposures and behaviors that threaten our reproductive health.”
Pollution a major contributor
According to the researchers, this is like a harbinger of declining health in men in general as sperm count is an important indicator of man’s overall health. Low sperm count is often associated with various underlying health issues, such as chronic illnesses, testicular cancer, and even decreased lifespans.
The researchers also believed that this issue was caused by modern environments and lifestyles, with all of it having broader implications for the survival of the human race.
Meanwhile, another study found that high levels of air pollution are one of the contributing factors to the decline in sperm count, with those living in more polluted areas showing higher rates of sperm decline.
However, the finding sparked a debate among experts in male fertility, with some saying the findings are real and urgent, while others were not convinced by the data because the methods of counting sperm have changed so much over time.
Nonetheless, nearly all experts agree that the issue needs more study.
