The approval process for glyphosate herbicide is disputed because the commercial formulations contain co-formulants, which are more toxic than glyphosate alone.

We measured the endocrine disruptive effects of co-formulants of six glyphosate herbicides. We did this by measuring the activity of aromatase, a key enzyme for the balance of sex hormones, in human placental cells, using a method validated by the OECD to assess endocrine disruptors.

The aromatase activity was significantly decreased both by the co-formulants alone and by the formulations, from doses 800 times lower than the agricultural dilution, while glyphosate alone only showed such an effect from one-third of the agricultural dilution.
