The role of circadian rhythmicity in reproduction

Kennaway, David J.·2005·Human Reproduction Update

Abstract

Circadian rhythmicity is evident in a wide range of physiological systems including the reproductive axis. The recent discoveries of rhythmic clock gene expression in peripheral tissues, including reproductive tissue, suggests that they may play an important role in optimizing fertility. The evidence for rhythmic control of reproduction from studies in laboratory animals is reviewed and where possible this includes evidence from human studies. Clock genes are highly conserved across species including humans and there is no reason to suggest that they are functionless in humans. The challenge issued here is for researchers to probe their function and the consequences of their disruption in both animal and human reproduction.

  • Circadian rhythms regulate many aspects of reproduction, including the timing of hormone release, ovulation, mating, and parturition.

    “Circadian rhythms regulate many aspects of reproduction, including the timing of hormone release, ovulation, mating, and parturition [91, 190].”
  • Gonadal hormones can influence other circadian parameters including endogenous period, rhythm amplitude, range of entrainment, zeitgeber sensitivity, and oscillator coupling.

    “Gonadal hormones can influence other circadian parameters as well, including endogenous period [7, 23, 47, 49, 91, 129, 212], rhythm amplitude [8, 17, 100], range of entrainment [49], zeitgeber sensitivity [23, 51, 79, 81], and oscillator coupling [126, 128, 187].”

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.
