Sperm counts worldwide have plunged 62% in under 50 years, Israeli-led study finds
Sperm counts worldwide have plummeted by 62 percent since 1973, according to new Israeli-led research. The research paper was published on Tuesday in the journal Human Reproduction Update. At the rate of current decline, fertility is projected to start to dip globally within a decade. Plummeting sperm counts, decreasing over 1 percent each year, are part of a broader decline in men’s health, including increased instances of testicular cancer, hormonal disruption, and genital birth defects.
