Can frogs change sex
A commonly used pesticide known as atrazine can turn male frogs into females that are successfully able to reproduce, a new study finds. Hayes of the University of California, Berkeley. Atrazine is banned in Europe. And since atrazine interferes with the production of the sex hormone estrogen, present in people and frogs, the findings could have implications for humans as well. Hayes and his colleagues raised 40 male African clawed frogs in water containing atrazine, from when they were larvae all the way up until sexual maturity.

What determines whether an animal becomes male or female? For frogs, sex is much more complicated than we thought. For some creatures, like reptiles and fish, sex can be heavily influenced by the environment. Sea turtles that grow up in warmer sand are more likely to become female , for example.

Lets face it; most things in the natural world revolve around sex. Specifically, making sure you survive long enough to find and impress a mate—then have lots of offspring. For lots of animals, sex is largely defined before birth, and depends on the chromosomes you receive during fertilisation. Yet for other animals like fruit flies, fish and some reptiles, things work a little bit differently. Depending on environmental and social conditions, some animals can change sex and then even change back again!
New research suggests that specific positions may serve to ensure that frog species only mate with their own kind. Things are heating up in frogville—researchers in India have discovered a completely new frog mating position. This new style of amplexus, as frog mating is known, is not for the prudish. Nor is this the first time a new position has been discovered in frogs. On closer inspection, the sex lives of frogs seem downright raunchy.
