Declining Sperm Counts In Men Worldwide Could Threaten Future Of Humanity, Study Warns By Study Finds for Natural Blaze
The continued decline of sperm counts in men all over the world is a looming crisis that threatens the very existence of humanity, a new report out of Israel warns.
The first major analysis of its kind reveals declining sperm counts among men globally, but specifically in South and Central America, Asia, and Africa. Alarmingly, the study also shows that the decline in sperm counts in North America, Europe, and Australia – reported by the same research team in 2017 – has continued and even accelerated in the 21st Century.
The team explains that sperm count is not only a measure of human fertility, but it’s also a marker of men’s health. Low levels have a connection to increased risk of chronic disease, testicular cancer, and shorter lifespans.

The study notes that the decline reflects a “global crisis” related to our modern environment and lifestyle, which has broader implications for the survival of the human race. An international team led by Professor Hagai Levine from the Hebrew University of Jerusalem’s Hadassah Braun School of Public Health conducted the research. Prof. Shanna Swan at the Icahn School of Medicine at Mount Sinai in New York, along with other researchers from Denmark, Brazil, Spain, Israel, and the United States were also part of the team.
Sperm counts have dropped by 50 percent
Study authors analyzed data from 53 countries, including seven years of data collection from 2011 to 2018, focusing on sperm count trends among men in regions not reviewed previously — specifically South America, Asia, and Africa. The data shows, for the first time, that men in these regions share the same “significant decline” in total sperm counts (TSC) and sperm concentration (SC). It’s the same trend seen in previous studies of men in North America, Europe, and Australia.
The study also shows an accelerated post-2000 decline in TSC and SC globally.
