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 کاملElectrotonic Coupling in the Pituitary Supports the Hypothalamic-Pituitary-Gonadal Axis in a Sex Specific Manner
Gap junctions are present in many cell types throughout the animal kingdom and allow fast intercellular electrical and chemical communication between neighboring cells. Connexin-36 (Cx36), the major neuronal gap junction protein, synchronizes cellular activity in the brain, but also in other organs. Here we identify a sex-specific role for Cx36 within the hypothalamic-pituitary-gonadal (HPG) ax...
متن کاملPituitary-gonadal axis in male undermasculinisation.
AIMS To study the value of assessing serum concentrations of luteinising hormone (LH), follicle stimulating hormone (FSH), testosterone, and dihydrotestosterone (DHT) in patients with male undermasculinisation not caused by androgen insensitivity. METHODS A retrospective study of a register of cases of male undermasculinisation (20 with abnormal testes, eight with 5alpha-reductase deficiency,...
متن کاملEffect of Camphor on Pituitary-Gonadal Hormonal Axis and Oogenesis in Adult Female Rats
Background & Objective: Camphor stimulates the nervous system and the circulatory system, reduces lactation, and prevents conception and embryo embedding. We investigated the effects of camphor on the pituitary-gonadal hormonal axis and concentration of steroidal hormones. Materials & Methods: The parameters investigated were concentrations of LH, FSH, estrogen, progesterone, and testosterone...
متن کاملDevelopment of the pituitary adrenal axis in fetal sheep twins.
Plasma cortisol increases in fetuses at term and is important for overall development. This study was designed to determine whether cortisol increases synchronously in twin fetal sheep and whether differences between twins contribute to the respective timing. Catheters were surgically implanted in fetal arteries in twins, the amniotic sac, and a maternal artery and vein. Blood was drawn daily u...
