NO sexual behaviour in newts [PDF]

open access: yesNature, 1996
Nitric oxide regulates sexual behaviour in mammals, but nothing is known about its effects in lower vertebrates. Here we show that nitric oxide has a role in male courtship behaviour but not in females of the urodele crested newt (Triturus carnifex)
