Many clinical and experimental data suggest that suckling can modify reproductive function. Among these are lactation amenorrhea, lactation diestrum and inhibition of castration changes in the anterior pituitary glands in puerperal rats. In the present work, FSH and LH content of the anterior pituitary glands in suckling and non-suckling rats following gonadectomy were assayed by means of the modified HCG-augmentation method of Steelman-Pohley and the modified OAAD method of Parlow, respectively. The results were as follows:(1) On Day 3 postpartum, all the mothers were gonadectomized and divided into the suckling and non-suckling groups. On Day 17 postpartum, they were sacrificed and pituitary FSH and LH content were bioassayed. The litters had a normal increase in body weight during the experimental period after the mothers were gonadectomized.(2) Both pituitary FSH and LH content in the castrated non-suckling group were approximately as high as the levels found in the simple castrated adult female rat. Those in the castrated suckling group were lowered to levels approximately equal to those in the intact suckling rats. The gonadotrophins of the suckling groups were significantly different from those in the non-suckling groups. Histological findings of the anterior pituitary glands were in agreement with the functional changes observed The present data confirm that suckling plays an important inhibitory role in pituitary gonadotrophin (FSH and LH) secretion in castrated puerperal rats. More physiological and useful therapeutic methods for the study of some reproductive disfunctions might be found through investigation of this mechanism, probably involving hypothalamico-hypophysial process.
