The neuropeptide kisspeptin has recently been implicated as having a critical role in the activation of the GnRH neurons to bring about puberty. We examined here the postnatal development of kisspeptin neuronal populations and their projections to GnRH ...

Multi‐ciliated cells in the infundibulum and ampulla (INF/AMP) epithelium are vacuolated in aging. Unique cellular susceptibility of the INF/AMP epithelial population and aging‐associated decline in ovarian artery circulation, which supports the ovary and INF/AMP, contribute to this region‐specific vacuolation phenotype, as a consequence of a mildly ...

Early preclinical work with gonadotropin-releasing hormone analogues
In this article, I provide a narrative remembrance of the many early proof-of-concept studies that were performed at the Jones Institute for Reproductive Medicine in the late 1980s and early 1990s. A group, led by the late Dr.

Chemometrics-aided Surface-enhanced Raman spectrometric detection and quantification of GH and TE hormones in blood [PDF]
This work explores the use of Surface-Enhanced Raman Spectroscopy (SERS) combined with artificial neural network (ANN) models to detect and quantify growth hormone (GH) and testosterone (TE) in the blood of Sprague Dawley (SD) rats. SERS spectra were recorded from blood samples of SD rats injected with GH, TE, both hormones, and non-injected controls ...

Kisspeptin is encoded by the Kiss1 gene, and kisspeptin signaling plays a critical role in reproduction. In rodents, kisspeptin neurons in the arcuate nucleus (Arc) provide tonic drive to gonadotropin-releasing hormone (GnRH) neurons, which in turn ...

The Effect of Assisted Reproductive Technologies on Human Sex Ratios
ABSTRACT Background Modern assisted reproductive technology (ART), including pre‐implantation genetic testing for aneuploidy (PGT‐A), has opened new avenues in understanding early embryonic events and has simultaneously raised questions about the impact of ART itself on sex ratios.

Stress hormones predict hyperbolic time-discount rates six months later in adults [PDF]
Objectives: Stress hormones have been associated with temporal discounting. Although time-discount rate is shown to be stable over a long term, no study to date examines whether individual differences in stress hormones could predict individuals' time-discount rates in the relatively distant future (e.g., six month later), which is of interest in ...

Stress rapidly suppresses in vivo LH pulses and increases activation of RFRP-3 neurons in male mice [PDF]
Restraint stress is a psychosocial stressor that suppresses reproductive status, including LH pulsatile secretion, but the neuroendocrine mechanisms underlying this inhibition remains unclear.
