Dear Sarah, I’ve heard a number of views on soy, particularly about the linkage between soy foods, infertility, and birth defects.
I've read that that phytoestrogens can impair fertility.
Humans and animals appear to be the most vulnerable to the effects of soy estrogens prenatally, during infancy and puberty, during pregnancy and lactation, and during the hormonal shifts of menopause. Of all these groups, infants on soy formula are at the highest risk because of their small size and developmental phase, and because formula is their main source of nutrient.
