Soy doesn't contain estrogen, it contains phytoestrogen which looks very much like estrogen but actually has the opposite effect and block "real" estrogen. Phytoestrogen can help to lower estrogen levels.

Do you know where real estrogen comes from? Female animals. Do you know the gender of basically all meat/egg/milk products comes from? Females. So that's where your estrogen comes from.

Not from Soy.
