Figure 1 In early gestation, maternal cortisol passing through the placenta inhibits corticotropin-releasing hormone (CRH) production by the fetal hypothalamus as well as adrenocorticotropic hormone (ACTH) production by the fetal pituitary gland. In this way, fetal cortisol production is inhibited... More

Figure 2 Conversely to early gestation, in later gestation, there is greater presence of 11-β hydroxysteroid dehydrogenase (11β-HSD) in the placenta. Active maternal cortisol is transformed into inactive cortisone by this enzyme. As a result, the fetal hypothalamic-pituitary-adrenal axis is now ab... More

ACTH=adrenocorticotropic hormone, CRH=corticotropin-releasing hormone, FSH=follicle-stimulating hormone, GH=growth hormone, GHRH=growth hormone-releasing hormone, GnRH=gonadotropin-releasing hormone, IGF=insulinlike growth factor, LH=luteinizing hormone, TRH=thyrotropin-releasing hormone, TSH=thyroid-stimulating hormone, T₃=triiodothyronine; T₄=thyroxine.
