Evidence Snippets

Many studies over the last 50 years have sought to identify the nature and mechanism of the "GnRH pulse generator" responsible for pulsatile LH release.

Linked Claims

Claim 1knowledge gapsupports2018Source 1DOI PubMed

Despite identifying the cells forming the pulse generator, the mechanisms of their synchronicity and the afferent hormonal and transmitter modulation establishing normal LH pulsatility remain largely unknown.

Claim 2localizationsupports2018Source 1DOI PubMed

Available data support an extrinsic GnRH pulse generator located within the arcuate nucleus.

Claim 3mechanism assessmentsupports2018Source 1DOI PubMed

The review states that there is little compelling evidence for an intrinsic pulse-generation mechanism based on interactions between GnRH neuron cell bodies.

Claim 4physiological patternsupports2018Source 1DOI PubMed

Pulsatile release of GnRH and LH is essential for fertility in mammals.
