In most conversations about fertility, women are the ones who have to worry. They've got to stop drinking, eat the right food, and worry about getting enough exercise and staying away from cigarettes. Men, on the other hand, can kick back and wait for show time. The good news is gender equality is finally coming to procreation; the bad news is that it comes at a cost: U.S. sperm counts are dropping at a rate of 1.5% a year, and in Europe and Australia, the drop is closer to 3%.
Studies from Center for Reproductive Epidemiology at the University of Rochester Medical Center and the European Science Foundation are reporting that overexposure to chemicals, and the lack of emphasis on male health and lifestyle — and its effect on fertility — are contributing to humanity's plummeting sperm count.
Apparently sperm production has been declining for the past fifty years, which isn't surprising since one of the main chemicals affecting sperm is found in take-out food containers and pesticides sprayed on fruits and veggies. So, you should probably learn to cook and start buying organic. Or, at least eat your take-out off a plate.
