It is probable that an important m which prolactin feedback at the hypothalamus ng alters secretion of gonadotrophin-releas hormone (GnRH), thus causing LH and etion to follicle-stimulating hormone (FSH) sec onadal become inappropriately low, relative to atility also steroid levels. Abnormalities in LH pul nd FSH occur, Prolactin may interfere with LH e action at the gonad, blocking progestero drogen synthesis, and may stimulate adrenal a segre ...
