This evidence includes a large body of U.S. government and National Institute of Health-sponsored human and primate research, in which controlled amounts of isoflavones from soy were fed and no effect on quantity, quality or motility of sperm were observed. In fact, a small-scale, preliminary study by Dr. Jorge Chavarro (1) found that "soyfood and soy isoflavone intakes were unrelated to total sperm count, ejaculate volume, sperm motility, or sperm morphology," which are the important measures of sperm quality and male infertility.
Misperceptions have developed regarding the estrogen-mimicking phytoestrogens and several men's health problems, including erectile dysfunction (ED). According to the American Urological Association Foundation, there is no association between soyfoods and ED.
