Brink of a fertility crisis: Scientist says plummeting sperm counts caused by everyday products
A 40-year-long study showed sperm counts have dropped by nearly half. Dr. Shanna Swan hypothesizes men will no longer produce sperm by 2045.
Her research found sperm counts have dropped by half in the last four decades. In 1973, the average ejaculate had 99 million sperm per milliliter. By 2011, the average ejaculate had 47 million sperm per milliliter.
“It’s not just the number of sperm. They have to be shaped well,” explained Swan, who described the upstream swim sperm have to travel for conception to occur.
