Too much Oestrogen in the water supplies perhaps? https://www.sciencedaily.com/releases/2010/12/101208125813.htm https://www.sciencedaily.com/releases/2010/12/

  That paper reminds me of Connections by James Burke. High incomes leads to better spending on food leading to more cattle production leading to more soy use and more dairy consumption, which leads to more intake of oestrogen in water, leading to lower testosterone counts in consumers, leading to lower fertility rates.

  That would only lead to higher oestrogen levels, I suppose.
