Gonadotropin-releasing hormone (GnRH) neurons integrate synaptic information in their dendrites in order to precisely control GnRH secretion and hence fertility. Recent discoveries concerning the structure and function of GnRH neuron dendrites have shed new light on the control of GnRH neuron excitability and GnRH secretion. This work suggests that GnRH neurons have a unique projection to the m...

Given the close relationship among neuroendocrine systems, it is likely that there may be common signals that coordinate the acquisition of adult reproductive function with other homeo-static processes. In this review, we focus on central nervous system insulin-like growth factor–1 (IGF-1) as a signal controlling reproductive function, with possible links to somatic growth, particularly during ...

Growth hormone when used in precocious puberty in combination with Gonadotropin releasing hormone analogue (GnRHa) instead of using GnRHa alone has been shown to improve final height prognosis. We report here a two-year follow-up of three cases of precocious puberty, two of whom were treated with a combination of GH and GnRHa and the third treated with GnRHa alone.

Two distinct subgroups of gonadotropin-releasing hormone (GnRH) neurons are involved in the control of luteinizing hormone secretion, at least in rats: one subgroup located in the mediobasal hypothalamus constitutes the GnRH pulse generator associated with opioid neurons, and the other located in the preoptic area constitutes the GnRH surge generator associated with gamma-aminobutyric acid neur...

(I)2.Coasting may reduce severe (III)3.Coasting longer than 3 days reduces in vitro fertilization pregnancy rates. (II-2)4.The use either luteinizing or human chorionic gonadotropin final oocyte maturation influence (I)5.There is no...

Abstract Background Hypogonadotropic hypogonadism (HH) is a rare condition in which there gonadal hypofunction due to absence of gonadotropin drive. In this condition, are very low serum levels gonadotropins. Pituitary gland may itself have some disease or disorder, be loss gonadotropin-releasing hormone (GnRH) pulses from the hypothalamus. The pharmacological interventions HH women formed basi...
