A new study reveals a significant decline in sperm counts across the globe. Here’s all you need to know.
Worry over declining sperm count on the rise
In addition to being an indicator of human fertility, sperm count is an indicator of men’s health. Low levers are associated with testicular cancers decreasing lifespan and increasing the risk of chronic diseases. Research also reveals this pattern is related to modern lifestyle and environment. Additionally, it can have deeper implications for the survival of the species. Published on Tuesday, in the journal of Human Reproduction Update the study uses data from 53 countries.
It includes data from 2011 to 2018 and focuses on the trend of sperm count among men, specifically focusing on Africa, Asia, and South America. Among men from these regions, a significant decline in sperm concentrations (SC) and total sleek count (TSC) has been observed. Additionally, it reveals an acceleration in the decline post the 2000s.
“India is part of this larger trend. In India, due to the availability of good data (including 23 estimates in our study, one of the countries with the richest data), we have more certainty that there is a strong and sustainable decline, but it’s similar globally,” stated Professor Hagai Levine. Levine is a Professor of Jerusalem at Israel’s Hebrew University.
More on the study
However, the study did not look into the causes behind the decrease in sperm counts. “Overall, we’re seeing a significant worldwide decline in sperm counts of over 50 percent in the past 46 years, a decline that has accelerated in recent years,” added Levine. Additionally, he also pointed to other studies revealing that disturbances in the development of the reproductive tract are linked with lifetime impairment and other markers of reproductive dysfunction.
“Additionally, lifestyle choices and chemicals in the environment are adversely affecting this fetal development. 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.,” explained Levine. “We urgently call for global action to promote healthier environments for all species and reduce exposures and behaviors that threaten our reproductive health,” he added.
