Abstract

The status of the neuroendocrine reproductive axis differs dramatically during various stages of development, and also differs in several critical ways between the sexes, including its earlier pubertal activation in females than males and the presence of neural circuitry that generates preovulatory hormone surges in females but not males. The reproductive axis is controlled by various hormonal and neural pathways that converge upon forebrain gonadotropin-releasing hormone (GnRH) neurons, and many of the critical age and sex differences in the reproductive axis likely reflect differences in the "upstream" circuits and factors that regulate the GnRH system. Recently, the neural kisspeptin system has been implicated as an important regulator of GnRH neurons. Here I discuss the evidence supporting a critical role of kisspeptin signaling at different stages of life, including early postnatal and pubertal development, as well as in adulthood, focusing primarily on information gleaned from mammalian studies. I also evaluate key aspects of sexual differentiation and development of the brain as it relates to the Kiss1 system, with special emphasis on rodents. In addition to discussing recent advances in the field of kisspeptin biology, this paper will highlight a number of unanswered questions and future challenges for kisspeptin investigators, and will stress the importance of studying the kisspeptin system in both males and females, as well as in multiple species.

  • ARC kisspeptin neurons likely promote pulsatile GnRH and LH release and respond to negative steroid feedback.

    “Kisspeptin neurons in the ARC are likely involved in promoting pulsatile GnRH and LH secretion and responding to sex steroid hormone negative feedback1,2.”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [2]

    Section 2.3 says ARC Kiss1 neurons likely mediate sex-steroid negative feedback and links their activity to GnRH and LH secretion. But Section 4.3 says that although kisspeptin pulses coincide with GnRH pulses, their anatomical source was not determined; the paper does not establish that ARC neurons promote pulsatile GnRH and LH release.

  • Kisspeptin made in the hypothalamus acts directly on GnRH cells via Kiss1R to drive the reproductive axis.

    “Subsequent studies from numerous species have now provided a wealth of information supporting the model that hypothalamic-derived kisspeptin directly activates GnRH neurons via kisspeptin receptor (Kiss1R) to stimulate the reproductive axis (reviewed in 1,2).”
  • Giving kisspeptin from outside raises blood LH and FSH in rodents, humans, and other species.

    “Early experiments determined that exogenous kisspeptin treatment of rodents and other species, including humans, robustly increases circulating LH and FSH levels (reviewed in 1,2).”

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.
