Why is soy bad for females?

Does eating soy increase estrogen?
According to a handful of studies, soy consumption may have a link to raising serum estrogen in humans (3), and potentially causing thyroid disorders (4). Animal studies have also suggested potential male infertility and breast cancer associated with soy consumption.
