Yeah I get all those things, I just don't think Boston is that different than the rest of the USA to account for the magnitude of change we see. A little change, sure. But we are talking a halving of bioavailable testosterone. Nevermind the fact that this isn't the only study showing declines in testosterone all over the world. https://www.forbes.com/sites/neilhowe/2017/10/02/youre-not-the-man-your-father-was/ https://www.forbes.com/sites/neilhowe/2017/10/02/youre-not-t... >Studies show that men’s testosterone levels have been declining for decades. The most prominent, a 2007 study in the Journal of Clinical Endocrinology and Metabolism, revealed a “substantial” drop in U.S. men’s testosterone levels since the 1980s, with average levels declining by about 1% per year. This means, for example, that a 60-year-old man in 2004 had testosterone levels 17% lower than those of a 60-year-old in 1987. Another study of Danish men produced similar findings, with double-digit declines among men born in the 1960s compared to those born in the 1920s.
