Why is nobody mentioning the potential biological basis for this? Men's sperm counts are going down 3% a year and have been consistently for over 30 years. Nobody knows exactly why, but environmental contamination through "xenoestrogens" (e.g. BPA in receipt paper) is a major theory. This is no freak trend and has been researched by over a thousand papers with no good answer (so don't reply with a pet hypothesis like exercise-- it's not). 1. https://www.theatlantic.com/family/archive/2018/10/sperm-counts-continue-to-fall/572794/ https://www.theatlantic.com/family/archive/2018/10/sperm-cou... 2. https://scholar.google.com/scholar?hl=en&as_sdt=0%2C33&q=sperm+decline+men&btnG= https://scholar.google.com/scholar?hl=en&as_sdt=0%2C33&q=spe...
