Reproductive epidemiology expert: Half of all men will have a sperm count of ZERO by 2050
One of the world's leading experts on environmental and reproductive epidemiology has predicted that, by 2050, most men around the world will have substantially no viable sperm for reproduction
Shanna H. Swan, a professor of environmental medicine and public health at the Icahn School of Medicine at Mount Sinai
and one of the co-authors of this latest research regarding global fertility rates, predicted an imminent "spermageddon" scenario
, which she said could cause severe existential issues for the future of humanity. (Related: Male fertility down 62% worldwide and it's still falling
Swan's study, co-authored with Hagai Levine of the Hebrew University of Jerusalem,
is a meta-analysis of previous studies regarding sperm counts
among men from all over the world, including South and Central America, Asia, Africa, North America, Europe and Australia.
Of the latter three regions, the team previously reported about decreasing sperm counts in 2017. They warned that this decrease has not only continued well into the 2020s but has also accelerated.
Sperm count an indicator of overall male health
Swan and Levine warned that sperm count is not just an indicator of human fertility, but of overall male health. They noted that low levels of sperm are associated with an increased risk of chronic disease, testicular cancer and a decreased lifespan.
"The troubling declines in men's sperm concentration and total sperm counts at over one percent each year as reported in our paper are consistent with adverse trends in other men's health outcomes, such as testicular cancer, hormonal disruption and genital birth defects, as well as declines in female reproductive health. This clearly cannot continue unchecked," Swan said.
Swan and Levine's study warned that, by 2050, the median man will have a sperm count of zero. This means that half of all men in the world will produce virtually no sperm at all, and the other half will produce so little sperm to be functionally infertile.
The study does not specifically investigate the causes of this global decline in sperm counts, but both Swan and Levine have no doubt that "lifestyle choices and chemicals in the environment" are playing an important role.
Lifestyle choices that men today can overcome include obesity and inactivity, which have powerful implications regarding the decline in male fertility
. Swan and Levine further warn that men should try their best to avoid prolonged exposure to endocrine-disrupting chemicals like BPA and phthalates.
Furthermore, the authors warn that women pregnant with male fetuses should avoid exposure to these same endocrine-disrupting chemicals, as exposure during the gestation period can be particularly problematic due to how these chemicals can adversely affect fetal development. Prolonged exposure is known to disturb the development of the reproductive tract, which serves to permanently impair fertility.
"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," said Levine. "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," Levine added.
