Some females are unable to reproduce.
Some animals have organs from both sexes. Many of the chemicals have been identified as organochlorine pesticides widely available and used by farms and households.

Crops grown is such soils are more susceptible to pests and disease, so farmers must use even more pesticides. Federal farm policy favors large-scale monocropping, making it difficult to financiallly sustain an organic farm.
