The BBC has just released a video on the dramatic findings of Dr. Shanna Swan's landmark research on declining sperm counts.
She is an environmental and reproductive epidemiologist and the author of the breakthrough book Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race.
"A man today has only about half the amount of sperm that his grandfather had," the video says. And women are less fertile at 21 than their grandmothers at 35.
"We're looking at the sperm concentrations, when we last looked at them–samples collected in 2011–the sperm concentration in Western countries was 47 million per milliliter down from 99 million per milliliter 39 years earlier," says Swan in the video.
Exposure to farmland intensively sprayed with herbicide appears to be one of the biggest hazards-for workers as well as for residents.
