Sperm count you can at least approximate by looking at per-capita birthrates.

- freedomben 3y agoThat's a bad metric because there are many other things that can affect per-capita birthrates. There are birth control products that make it so even the most virile man with an explosive sperm count getting laid isn't going to result in a birth. People have have choosing less and less to have children, and deferring those choices to later in life, and I don't think that has anything to do with microplastics.
