This review provides an outline of how our understanding of the neuroendocrine control of the hypothalamo-pituitary–gonadal axis has evolved since the publication of Geoffrey Harris’ renowned monograph in 1955. Particular attention is directed to the neurobiology underlying pulsatile GnRH release from the hypothalamus, the neuroendocrine control of ovarian cycles, puberty and seasonality of gon...
The evolution of sex steroids in the plasma and gonads of the lizard Podarcis s. sicula during the postreproductive period shows that these hormones could be involved in determining refractoriness. In the male, during this phase, the oestradiol could lower the hypothalamo-hypophyseal system through a negative feed-back. In the female a similar role could be assigned to progesterone.
conclusions religiosity has been used as a coping mechanism among blacks. religiosity may also be related to stress regulation among black youth. future studies need to test complex associations between race, sex, religiosity, chronic stress, coping, and function of hypothalamo-pituitary-adrenal (hpa). it is not known whether male black youth who are and those who are not religious differently ...
CONTEXT Fibroblast growth factor (FGF) 8 is important for GnRH neuronal development with human mutations resulting in Kallmann syndrome. Murine data suggest a role for Fgf8 in hypothalamo-pituitary development; however, its role in the etiology of wider hypothalamo-pituitary dysfunction in humans is unknown. OBJECTIVE The objective of this study was to screen for FGF8 mutations in patients wi...
Control of the secretion of ACTH appears to involve several mechanisms. It is dependent upon the release, from neurones in the hypothalamus, of corticotrophin releasing factor, which is probably a complex including CRF-41 and vasopressin. The secretion of the complex is influenced by various central inhibitory and excitatory nervous pathways. The releasing factor is conveyed by the hypophyseal ...
BACKGROUND & OBJECTIVES Postmenopausal women constitute an ideal model for studying the extent of hypothalamo-pituitary gonadal (HPG) axis suppression in critical illness as the gonadotropins are normally high and non-cyclical in them. The objective was to assess the impact of acute severe illness in postmenopausal women on the HPG axis and the activities of the hypothalamo-pituitary-adrenal (H...
Abstract Introduction Cocaineand amphetamine-regulated transcript peptides have been implicated in the endocrine and autonomic regulation, food intake and anxiety. Anatomical studies demonstrate that cocaineand amphetamine-regulated transcript mRNA and peptides are expressed intensely in the hypothalamo-pituitary-adrenal gland axis and sympatho-adrenal system. In parallel with the anatomical st...
