摘要: The effects of hormones upon the development behavioural characteristics have been reviewed extensively in past few years (Young, Goy & Phoenix 1964; Levine Mullins 1966; Phoenix, Resko 1968; Whalen 1968). Much information contained these reviews is limited to two species rodents (rat and guinea-pig). A limitation which perhaps has greater consequences for theoretical considerations restriction a set traits requiring hormonal activation adulthood before they can be displayed by individual. An analogous situation classical reproductive physiology would study neonatal or foetal hormone treatments prostatic secretory activity. In such study, prostate remain non-secretory unless activated appropriate essential supplied during either gonad injection. most studied similar nature include testosterone-dependent responses male sexual repertoire like mounting, intromission, ejaculation oestrogen-progesterone dependent female as oestrous mounting activity lordosis.
