Sperm Count Among Men Has Dropped 60 Percent Globally Over Past 45 Years: Study

Epoch Times | Nov. 21, 2022

Sperm counts worldwide have halved over the past 45 years, according to a study published on Nov. 15 in the journal Human Reproduction Update.

The study was conducted by an international team of researchers led by professor Hagai Levine of Hebrew University of Jerusalem’s Hadassah Braun School of Public Health.

They aimed to examine trends in sperm count among men from all continents and analyzed 223 studies based on sperm samples taken from over 57,000 men across 53 countries including the United States, Europe, and Australia between 1973 to 2018.

Previously, a 2017 study conducted by the same team of researchers reviewed sperm count data in North America, Europe, Australia, and New Zealand. The new analysis updates that review to include data from Central and South America, Asia, and Africa for the first time.

Researchers in the latest study found an “appreciable decline” in sperm count during that time period.
