Hormonal birth control has reshaped testosterone levels in men through environmental exposure. The video uses nature analogies to explain how widespread contraceptive use affects biology in both sexes.

But one of the reasons I think we have a decline in testosterone, especially in young men, is that 85% of women are on industrial hormonal birth control at some point in their life. So now, if you're a guy walking around in a world where there's no fertile women, what is your biology going to do? You're going to have less testosterone because there's no need for it. And the evidence I have to support that comes from trees going back about 50 years now. We started planting only male trees in cities because male trees don't make a lot of debris that you have to clean up in those cities when there are no girl trees around for the boy trees, the boy trees make 10 times more pollen, because there's a sensing mechanism to know, oh, my gosh, the other trees must be very far away. So let me make extra pollen in the hopes that I can reach one. And doesn't it make sense that our own human hormones, entirely invisible to our conscious mind, would be affected by those around us? So when we use hormonal disruptors as birth control, it affects men and women.
