... of luteinizing hormone (LH) pulse generation. Methods: We employed a suite of in vivo optogenetic and chemogenetic approaches with serial measurements of LH to determine the impact of selectively activating NPY/AgRP neurons on dynamic LH secretion. In addition, electrophysiological studies in ex vivo brain...

...Michael J. Kreisman; Richard B. McCosh; Katherine Tian; Christopher I. Song; Kellie M. Breen Introduction: Two common responses to stress include elevated circulating glucocorticoids and impaired luteinizing hormone (LH) secretion. We have previously shown that a chronic stress level...

... neurotransmitters and potentially contribute to reproductive axis regulation. Methods: Using female urine as a pheromone stimulus, MeA Kiss neuronal activity was analysed and serum luteinizing hormone (LH) was measured in male mice. Next, using a chemogenetic approach, MeA Kiss neurons were bi-directionally...

... investigation aimed to determine (1) if a lack of cyclical estrogen exposure of the GnRH neuronal network in the life-long hypogonadotropic Gpr54 -null mice contributed to their failed negative feedback mechanism and (2) the cellular location of disrupted kisspeptin-Gpr54 signaling. Plasma luteinizing hormone...

Blood samples were collected before and after canine KP-10 administration for the measurement of plasma luteinizing hormone (LH, all doses), follicle-stimulating hormone (FSH) and oestradiol (1-30 μg/kg). From 0.2 μg/kg...

Methods: Boys with precocious puberty, who were normal weight, overweight, and obese underwent GnRH stimulation tests between 2003 and 2010. Subjects were...

...Jessicah S.P. Collins; John C. Marshall; Christopher R. McCartney Context: Early pubertal luteinizing hormone (LH), and by inference gonadotropin-releasing hormone (GnRH), pulse secretion is marked by high nocturnal but low daytime frequency; however, the underlying mechanisms remain unclear...

... of an upregulation of central acetylated melanocortin production. Methods and Results: Lean ovariectomised (OVX) ewes received intracerebroventricular (i.c.v.) infusions of leptin (or vehicle) for 3 days, which upregulated proopiomelanocortin (POMC) mRNA and restored pulsatile luteinizing hormone (LH) secretion...
