Regulation of gonadotropins by corticotropin-releasing factor and urocortin
Frontiers in Endocrinology, 2013 While stress activates the hypothalamic-pituitary-adrenal (HPA) axis, it suppresses the hypothalamic-pituitary-gonadal (HPG) axis. Corticotropin-releasing factor (CRF) is a major regulatory peptide in the HPA axis during stress.

Novas perspectivas no diagnóstico do hipogonadismo pediátrico masculino: a importância do AMH como marcador de células de Sertoli [PDF]
, 2011 Sertoli cells are the most active cell population in the testis during infancy and childhood. In these periods of life, hypogonadism can only be evidenced without stimulation tests, if Sertoli cell function is assessed.
