Amid the many global problems we are facing today, one of humanity’s biggest issues comes relatively unnoticed: the decline in reproductive health, especially for males.
Specifically, the sperm count of males in the West has significantly decreased by 59% between 1973 and 2011 due to chemicals found in everyday items, a co-authored by Dr. Shanna Swan in 2017 has found.
In the study, which has been making headlines around the globe, scientists noted that sperm count is of considerable public health importance for several reasons including the decline of male fertility and the rise of other health issues, such as testicular cancer.
“If you look at the curve on sperm count and project it forward—which is always risky—it reaches zero in 2045,” Swan said in her new book titled “Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race,” as cited by Axios on Feb. 24.

In the book, Swan also noted that aside from the decline in sperm count, penis size and testes volume have been decreasing among humans in the past few decades.
“The current state of reproductive affairs can’t continue much longer without threatening human survival,” Swan writes in the book.
