Where can I read about "dropping male fertility" as a medical thing? Just taking a blind guess, as someone who doesn't follow the medical field, I would suggest that increases in "infertility" are much more likely to be caused by the older age at which people are becoming interested in "fertilization" than environmental factors causing biological malfunctions. In other words, it's not that reproductive systems are breaking faster, it's just that people aren't using them until they're worse for wear.

- sreaching 9y agotestosterone levels have declined in most developed countries when comparing similar age cohorts over time. See the following studies: from Finland - https://www.ncbi.nlm.nih.gov/pubmed/23161753 https://www.ncbi.nlm.nih.gov/pubmed/23161753. from USA - https://academic.oup.com/jcem/article/92/1/196/2598434 https://academic.oup.com/jcem/article/92/1/196/2598434 it is a bit of a medical mystery because the trend cannot be fully explained by lifestyle factors like weight gain.
- 52-6F-62 9y agoThis discussion came up sometime within the past few months. It was really interesting. I recall mentioning some research into the effects of food/organics preservatives (namely Parabens) and low testosterone: https://www.ncbi.nlm.nih.gov/pubmed/12419695 https://www.ncbi.nlm.nih.gov/pubmed/12419695
