Are chemicals shrinking your penis and depleting your sperm? Here's what the evidence says
ABCA doomsday scenario of an end to human sperm production has been back in the news recently, now with the added threat of shrinking penises. Selective reporting In 2017, Swan and several colleagues published an exhaustive review study showing an apparent drop in men's sperm counts of 59.3 per cent between 1973 and 2011. The problem with extrapolation Swan's 2017 study boils down to a straight descending line drawn between sperm counts of groups of men studied at different times between 1973 and 2011. We know sperm counts of men in the early 1940s were around 113 million sperm per ml of semen, not the roughly 140 million/ml you get from extrapolating backwards from Swan's research. But only a single study, of 383 young men from the Veneto region in northeastern Italy, links men's penis size to the types of chemicals Swan attributes to declining sperm counts.
