Abstract
Plasma prolactin (PRL) and vitellogenin (VTG) concentrations were dete rmined during the annual reproductive cycle of the newt Triturus carni fex Laur. Plasma PRL was measured by a radioimmunoassay using purified newt (Cynops pyrrogaster) PRL as standard and radioligand and its ant ibodies. Using ELISA, plasma VTG titers were related to ovarian weight . The trends in PRL differed in the two sexes: the PRL changes seemed to be related with vitellogenic processes in the female, whereas they were more related to reproductive behavior in the male.
