Update: Soy and Sperm (again)

Just added to Another Internet Soy Article:

A 2010 study found that low (1.64 mg/day) or high (61.7 mg/day) isoflavone consumption for 8 weeks did not significantly affect semen volume or sperm concentration, sperm count, total motile sperm count, or sperm motility in a sample of 32 healthy adult males (15).

62 mg is the amount of isoflavones found in about 2.5 cups of soymilk.

Thanks, Marco!
