In Agricultural Areas, Male Toads Feminized

(Beyond Pesticides, July 17, 2008) In a new study published in Environmental Health Perspectives, researchers have found an increased occurrence of intersex toads in areas with greater agricultural land cover. This points to a link between certain pesticides and endocrine disruption, a change in the hormonal balance that can have sexual and reproductive effects. Such […]
