There's a beautiful book I don't know if you've read it called countdown and it's about the sperm counts going down in across the world and I actually brought her onto my podcast the woman who wrote the book and said that there's one chemical that's reducing sperm counts more than any.

Why people recommend it
Count Down by Shanna H. Swan and Stacey Colino is a book that examines the impact of environmental toxins, specifically endocrine disruptors like phthalates and microplastics, on human reproductive health and development. On The Joe Rogan Experience, Joe Rogan repeatedly brought up the book, calling it terrifying and emphasizing how exposure to chemicals leached from plastics and used in agriculture is radically affecting the way children develop and threatening human fertility. Rogan expressed shock that there is no large-scale effort to reverse course on these pressing environmental issues. Similarly, Dr. Mindy Pelz discussed the book on The Diary Of A CEO with Steven Bartlett, noting that Swan's work highlights the alarming global decline in sperm counts driven by chemical exposure. Pelz mentioned that she even invited the author onto her own podcast to discuss which chemicals are most responsible for reducing sperm counts. Throughout these podcast appearances, the speakers underscored the urgent warning presented in the book regarding modern pollution and its threat to the future of the human race.
