Most frogs use external fertilization, in which a female and male release their eggs and sperm around the same time.
What causes hermaphroditism in frogs?
Working with the African clawed frog, Hayes and his colleagues showed in 2002 that tadpoles raised in atrazine-contaminated water become hermaphrodites – they develop both female (ovaries) and male (testes) gonads.
