African Clawed Frog
Scientists and researchers have began observing spontaneous gender changes in the frogs in their labs. More recently, they began seeing the same thing happening in the wild. However, in both cases it did not seem like a natural process. A large number of male frogs are becoming female, developing functional reproductive organs. And the reason for this turned out to be a common and popular weed killer chemical – atrazine.
This chemical has now been banned in Europe. When it would get absorbed into the soil and then later carried to rivers, it would completely mess up the hormone levels in the bodies of these frogs. By suppressing testosterone and boosting estrogen the chemical managed to make many of these frogs turn from male to female.
