The behavioural effects observed following repeated injections of pregnant mare serum (PMS), human chorionic gonadotropin (HCG), testosterone propionate (TP), oestradiol benzoate (OB) or progesterone (P) were accompanied by significant effects on reproductive morphology and on plasma levels of pituitary-gonadal hormones. The testes weight was decreased by TP and P treatment, FSH secretion was inhibited by the three steroid preparations (TB, OB, P) but LH was not suppressed following OB injections (only TP and P were effective in this respect). The behavioural effects previously described are discussed in the light of the present results and a possible unitary mechanism is proposed for the inhibition of social display by TP, OB and P. Correlations between individual variations of hormone levels and of behaviour are presented: these are shown to be significant in only a few cases. Finally, a tentative model is proposed to explain the endocrine basis of the annual reproductive cycle of male ducks.
重复注射孕马血清（PMS）、人绒毛膜促性腺激素（HCG）、丙酸睾酮（TP）、苯甲酸雌二醇（OB）或孕酮（P）后观察到的行为效应，伴随着对生殖形态以及垂体 - 性腺激素血浆水平的显著影响。TP和P处理使睾丸重量降低，三种类固醇制剂（TB、OB、P）抑制促卵泡激素（FSH）分泌，但注射OB后促黄体生成素（LH）未被抑制（仅TP和P在这方面有效）。根据目前的结果讨论了先前描述的行为效应，并提出了一种可能的统一机制来解释TP、OB和P对社会行为表现的抑制作用。呈现了激素水平个体差异与行为之间的相关性：结果表明仅在少数情况下具有显著性。最后，提出了一个初步模型来解释雄鸭年度生殖周期的内分泌基础。
