Abstract
THE antigonadal role of prolactin during the post-partum period seems well established in many species1–3. But mechanisms by which prolactin may act are not yet known. There is some evidence that prolactin may exert its inhibitory function at the ovarian level4,5, but an eventual action on the hypothalamo–hypophysial axis cannot be excluded. Experiments described here have been designed to resolve this problem.
