Maybe the Republicans should push more environmentalism. Seems these contaminants in the environment are what is creating all these soy boy Democrats!
"Sperm counts in Western countries have dropped by more than 50 percent since the 1970s. At the same time, men’s problems with conceiving are going up: Erectile dysfunction is increasing and testosterone levels are declining by 1 percent each year.
“The current state of reproductive affairs can’t continue much longer without threatening human survival,” warns Mount Sinai fertility scientist Dr. Shanna Swan in her book, “Count Down” (Scribner), out Tuesday. “It’s a global existential crisis....”
Worldwide fertility has dropped by 50 percent between 1960 and 2015. The United States has a total birth rate that is 16 percent below what it needs to replace itself. Though there are obvious factors at play (couples are conceiving later and opting to have smaller families), Swan argues that the issues run deeper than personal choice.
Rates of miscarriages are on the rise and girls are experiencing earlier and earlier puberties (in some cases before the age of 8). “In some parts of the world, the average twenty-something woman today is less fertile than her grandmother was at 35,” Swan writes....
Normal sperm count ranges from 15 million sperm per milliliter to 200 million per milliliter. Though the World Health Organization deems a rate below 15 million as “low,” Swan argues that anything below 40 million creates challenges for reproduction. Today the average male is nearing that number at 47.1 million sperm per milliliter. Compare him to his father, who had an average of 99 million sperm per milliliter, and it’s clear that this is a deeply worrying trend.
Not only do men today have less sperm than their fathers, but they also have lower testosterone levels. A 2006 study showed that a 65-year-old man in 2002 would have testosterone levels that are 15 percent lower than a 65-year-old man in 1987. A similar drop has been noted in young adults and adolescents, according to a 2020 Urology Times Journal article...."
