I think it's pretty safe to assume no chemicals are good for us. Thanks, Henry!

For those who don't want to read on-- Many synthetic chemicals, including a number of pesticides, are probable "endocrine disruptors" that, typically, mimic female hormones or counteract male hormones. These, along with actual female hormones that are in our rivers downstream from cities (the consequence of using birth control pills), have the potential to keep developing male young from being fully masculinized. Probable evidence of these effects has been found in fish and frogs, which are particularly exposed owing to their spawning and developing in the water.

The paper Henry linked investigated ways that the conazole-type fungicides could disrupt hormones at the cellular level. They found that tebuconazole is likely an effective disruptor. Tebuconazole is the ingredient in Bayer Disease Control for Roses, Flowers, and Shrubs and some Bayer combo products. Women who are or might become pregnant should try to limit their exposure to endocrine disruptors.
