Efeito do estresse sobre a secreção de prolactina em ratas nulíparas e primíparas no estro

Abstract

The reproductive experience (set of pregnancy, childbirth and lactation), is associated with changes in hormone secretion, reducing hormones such as steroids and prolactin. Prolactin plays an important role in the reproductive process, especially in lactation, controlling the production and composition of milk. This hormone responds to stressful stimuli, and its response is dependent on blood prolactin concentrations before stress. The aim of this study is to evaluate the influence of stress on prolactin secretion in nulliparous and primiparous rats during estrus, continuing our studies.
