Over-consumption of soy has been seen to have adverse effects in women. One of the main components of soy is an isoflavone called genistein.

Too much estrogen, too many hormones in the body can lead to weight gain, specifically fat in the breasts and hips, gallstones, fibroids and cancers found mainly in women like breast cancer, ovarian and uterine cancer. If increased estrogen from soybean consumption leads to side effects like this in the female body than it naturally will transfer the same positive and negative benefits to a growing fetus.
