Hormonell aktive Substanzen könnten zum weltweiten Artensterben von Amphibien beitragen. Einige Stoffe (z.B. aus Pharmaka) kommen in „biologisch relevanten“ Konzentrationen in Gewässern vor, so dass sie das Hormonsystem der Tiere und die Geschlechtsentwicklung beeinflussen. Forscher des Leibniz-Instituts für Gewässerökologie und Binnenfischerei (IGB) und der Universität Wroclaw verglichen bei drei Amphibienarten die Wirkungen des Pillen-Östrogens Ethinylestradiol (EE2) auf die Geschlechtsentwicklung. Die in „Scientific Reports“ publizierte Studie zeigt, dass EE2 zur vollständigen Verweiblichung genetischer Männchen führen kann. Ohne molekulare Feststellung des genetischen Geschlechts blieb dies bislang teilweise unbemerkt.
