| description | The adenohypophysis produces among other hormones prolactin, which plays an important role in reproduction, especially on the mammary glands and lactation of mammals. Prolactin is tonically controlled by tufo-infundibular dopamine, but several studies indicate that prolactin secretion is altered by the action of glucocorticoids and, therefore, is related to stress. However, the exact contribution of corticosteroids in the control of prolactin secretion is poorly understood. On the other hand, it is also known that reproductive experience can modify prolactin secretion by adenohypophysis. Thus, the present study aims to study the hormonal relationships of the hypothalamic-pituitary-adrenal axis, in particular, the glucocorticoid relationship on prolactin secretion as a function of the reproductive experience in females during lactation. The results show that reproductive experience may be a factor modifying the sensitivity of the neuroendocrine response of prolactin secretion to glucocorticoids. However, more studies are needed to understand the possible mechanisms involved, as well as possible modifications in this response as a function of the reproductive status of the females. |
