Also worth noting what kind of GE we're talking about: https://en.wikipedia.org/wiki/Genetically_modified_soybean https://en.wikipedia.org/wiki/Genetically_modified_soybean tl;dr: mostly pesticide resistance. That has significant environmental/economic consequences, but those edits (probably) don't change how soy interacts with endocrine receptors.

Pesticide resistant crops being completely doused in glyphosate right before harvest probably does have an impact on health though. http://people.csail.mit.edu/seneff/ITX_2013_06_04_Seneff.pdf http://people.csail.mit.edu/seneff/ITX_2013_06_04_Seneff.pdf

    Absolutely, but that's not isolated to soybeans. Plus we've been abusing toxic pesticides for decades - that's just greedy human shortsightedness.

  Ive only heard of herbicide resistance, aka roundup ready. The bt modification (Cry1Ac protein from Bacillus thuringiensis), afaik, is itself a pesticide, or produces pesticide. Edit: I suppose "pest" could refer to weeds and insects? I may have been thinking insecticide.

I don't know how different the number is for the US specifically but around 85% of soy grown is used for animal feed. I don't know what the intersection of GMO and animal feed is, but anecdotally, a lot of the soy I see for human consumption is non-gmo. But that raises the question of what soy's GMO status has to do with its affect on the endocrine system?

Is there any evidence to suggest that genetically-modified soy has higher or lower phytoestrogen content as compared with non-GMO soy?

  Soy (and other crops) are modified to be resistant to pesticides and pests, so I presume it makes no difference for their phytoestrogen contents. For example, glyphosate ("Roundup") resistant crops are only modified to have a different version (which still preforms the same function) of the enzyme that would otherwise have been inhibited by glyphosate, IIRC.
