Chapter 2 Hypothalamic Neural Systems Controlling the Female Reproductive Life Cycle

Abstract

The hypothalamic-pituitary-gonadal (HPG) axis undergoes a number of changes throughout the reproductive life cycle that are responsible for the development, puberty, adulthood, and senescence of reproductive systems. This natural progression is dictated by the neural network controlling the hypothalamus including the cells that synthesize and release gonadotropin-releasing hormone (GnRH) and their regulatory neurotransmitters. Glutamate and GABA are the primary excitatory and inhibitory neurotransmitters in the central nervous system, and as such contribute a great deal to modulating this axis throughout the lifetime via their actions on receptors in the hypothalamus, both directly on GnRH neurons as well as indirectly through other hypothalamic neural networks. Interactions among GnRH neurons, glutamate, and GABA, including the regulation of GnRH gene and protein expression, hormone release, and modulation by estrogen, are critical to age-appropriate changes in reproductive function. Here, we present evidence for the modulation of GnRH neurosecretory cells by the balance of glutamate and GABA in the hypothalamus, and the functional consequences of these interactions on reproductive physiology across the life cycle.

  • The occurrence of the LH surge is coincident with a decline of GABAergic transmission to both POA kisspeptin neurons and GnRH neurons.

    “and that its occurrence is coincident with a decline of GABAergic transmission to both POA kisspeptin neurons and GnRH neurons [106,107].”

    From Fibromyalgia pathogenesis explained by a neuroendocrine multistable model (2024) · cites this paper as [107]

    Section V.C reports that GABA levels in the POA-AH decrease just before the LH surge and suggests this disinhibits GnRH neurons. It does not report a decline in GABAergic transmission to POA kisspeptin neurons; the Conclusion mentions kisspeptin only as a neuropeptide feeding into the circuitry. The evidence also places the observed GABA decline before, rather than precisely coincident with, the surge. Page numbers were not available in our copy. (LLM, conf=0.89)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
