So I read about the sperm count decline in men in rich countries. I wonder if this is accompanied by other changes for example in testosterone levels or in other hormones linked with the reproductive system ? Also other measures such as semen volume ? Example report on this issue https://www.sciencedaily.com/releases/2017/07/170726110954.htm

Also, the report shows a steady decline - will this continue and what would be the bottoming out of this trend ?

  • $\begingroup$ With an aging population, thanks to better medical science lower average testosterone and sperm is to be expected. If the study is not accounting for this it is pointless. $\endgroup$
