Researcher: Pesticide 'Castrates' Male Frogs
Posted: March 7th, 2010, 2:00pm CST
Atrazine is widely used as weedkiller on American farms. And a new study shows this common chemical may have gender-bending effects on frogs. Host Guy Raz talks to biology professor Tyrone Hayes about his work with atrazine and frogs. Hayes found that 9 of every 10 male frogs he exposed to atrazine became chemically castrated. And that other 1 out of every 10? Well, he became a she.
