All soy products, including edamame, contain large quantities of plant estrogen such as isoflavones. Though the research is inconclusive and insufficient, some studies suggest that neonatal exposure to isoflavones can have negative effects on reproductive development later in life.
12. Fertility problems
Pregnant women are at risk of consuming genetically-modified soy instead of organic soy. Crops that are genetically-engineered may have food safety issues and may increase the risk of fertility problems and affect reproductive health. Genetically-modified and conventional soy receive herbicide treatment containing a substance called glyphosate, which may increase the risk of miscarriages.
