The hypothalamo-pituitary–gonadal axis
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...
متن کاملDevelopmental Disorders of the Hypothalamo-Pituitary Axis
Short stature is defined by a height that lies <-2SDS below the mean. Recent molecular advances have led to the identification of the underlying aetiology in a number of cases that were previously believed to be “idiopathic”. This review will briefly discuss the advances in the field of pituitary development and the GH-IGF-1 axis that have led to the unravelling of the genetic basis to a number...
متن کاملSpinal and supraspinal analgesic effects of Nimodipine : The role of Hypothalamo-Pituitary-Adrenal(HPA) axis .
Nimodipine, an L-type calcium channel blocker, can induce analgesia. However, it is not clear that this analgesic effect is at the level of spinal or supraspinal pain pathway. In addition, it has been reported that the analgesic effect of nifedipine, another L-type calcium channel blocker is related to the HPA axis, but there is no report indicating the role of this axis in the analgesic eff...
متن کاملTesticular feed back on the hypothalamo - pituitary axis in rainbow trout ( Salmo gairdneri R . )
A testicular feed back on the hypothalamo-pituitary system was studied in male rainbow trout (Salmo gairdneri) after bilateral castration and steroid or testicular supplementation. Experiments were carried out at various periods of the spermatogenetic cycle ; in March-April (resting stage), June (initiation of spermatogenesis), October (end of spermatogenesis and before spermiation), and Decemb...
متن کاملRecovery pattern of hypothalamo-pituitary-testicular axis in patients with macroprolactinomas after treatment with cabergoline
BACKGROUND & OBJECTIVES Hyperprolactinaemia affects testicular functions by influencing hypothalamo-pituitary-testicular (HPT) axis at various levels. Available literature on the level of defect, time course of improvement of gonadal functions and its relation with decline in prolactin levels is scanty. We carried out this study to evaluate the HPT axis in patients with macroprolactinomas, befo...
