No More Tofu For Me

RE: Soy may water down little swimmers: sperm research

CBC - A study published in the July 24 issue of Human Reproduction finds that men who eat half a serving of soy per day - such as 115 g of tofu or 240 ml of soy milk - had lower concentrations of sperm than men who didn't eat soy.

Hm...I wonder if this includes soy sauce.
