Plastics definitely are lowering testosterone levels worldwide.

  Can you cite any evidence of this?

      How about a source that isn't a magazine interview from someone trying to sell their book? There are sibling comments elsewhere in this thread that go into much greater detail than I can about how the link between plastic and fertility is tenuous at best. But the most significant piece of evidence against it IMO is that plastics are more or less evenly distributed. You don't have a lot more exposure at various socio-economic levels. But higher socio-economic class has a distinct negative correlation with obesity.

    Not specifically testosterone or world-wide: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7967748/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7967748/ >> In a further study, following 28 days exposure by oral gavage (100 μL PS-MPs (10 mg/mL)) PS-MPs (0.5, 4, 10 μm) bioaccumulate in mice testis altering spermatogenesis progression, SPZ morphology, testosterone biosynthesis and body weights and inducing inflammatory response [73]; interestingly, in vitro MPs enter into germ cells, Sertoli and Leydig cells [73].
