为了确定内源性催乳素（PRL）参与雄性蝾螈（Cynops pyrrhogaster）的求偶行为的表达，将抗同源PRL的抗血清给予在野外表现出求偶行为并被带到实验室的雄性蝾螈。还研究了抗血清对陆生生境的偏好性的影响。在第一次注射抗血清后24小时内，求偶行为的发生率和频率与免疫前注射血清的蝾螈相比显著下降。此后抗PRL血清诱导的下降变得更加明显。这些动物开始喜欢陆地栖息地。停止注射抗血清和给予催乳素在一定程度上恢复了求偶行为的表达，并改变了它们的栖息地偏好。结果表明，内源性PRL参与了求偶行为的表达，以及在水生生境的偏好。
In order to ascertain the involvement of endogenous prolactin (PRL) in the expression of courtship behavior by the male newt, Cynops pyrrhogaster, antiserum against homologous PRL was administered to male newts, which had been exhibiting courtship behavior in the field and had been taken to the laboratory. The effect of the antiserum on the preference of terrestrial over aquatic habitats also was investigated. Within 24 hr of the first injection of antiserum, both incidence and frequency of courtship behavior declined markedly compared with those in the preimmune serum-injected newts. The anti-PRL serum-induced decline became more conspicuous thereafter. These animals came to prefer a terrestrial habitat. Cessation of antiserum injection and administration of PRL restored the expression of courtship behavior to a certain extent and altered their habitat preference from terrestrial to aquatic. The results strongly suggest the involvement of endogenous PRL in the expression of courtship behavior as well as in the preference of aquatic habitat.
