    P E Chappell
    Department of Reproductive Medicine, University of California, San Diego, School of Medicine, La Jolla, CA 92093 0674, USA
    J Neuroendocrinol 17:119-30. 2005
    ..Multiple possible steroidal and neuronal contributions to GnRH surge generation are discussed, in addition to how these signals of disparate origin may be integrated at the cellular level to initiate this crucial reproductive event...

    Ravid Sasson
    Department of Reproductive Medicine, University of California at San Diego, La Jolla, CA 92093 0674, USA
    Neuroendocrinology 84:353-63. 2006
    ..It is suggested that the stimulatory effect of orexin A on GnRH transcription and release may also occur directly at the level of GnRH neurons in vivo...

    Patrick E Chappell
    Department of Reproductive Medicine, University of California, San Diego, School of Medicine, La Jolla, California 92093 0674, USA
    J Neurosci 23:11202-13. 2003
    ..This effect persists in normal light/dark (LD) cycles, suggesting that a suprachiasmatic nucleus-independent endogenous clock in GnRH neurons is required for eliciting normal pulsatile patterns of GnRH secretion...

    J D Alvarez
    Department of Pathology and Laboratory Medicine, University of Pennsylvania School of Medicine, Philadelphia, PA, USA
    J Biol Rhythms 23:26-36. 2008
    ..Other hormonal defects in male Bmal1 KO mice suggest that BMAL1 also has functions in reproductive physiology outside of the testis. These results enhance understanding of how the circadian clock regulates reproduction...
