Abstract

Circadian rhythms in the uterus are regulated by clock genes that exhibit phasic changes, which are lost after decidualization.

  • Clock genes in the endometrium show rhythmic expression that is altered post-decidualization.
  • Rhythmic expression of clock genes in the myometrium is linked to uterine contractions and the timing of labor.
  • Estrogen and progesterone are associated with modulation of core clock genes and the decidualization process.
  • Melatonin, a key hormone from the central clock, influences the uterine environment and may affect delivery timing.
  • Disruption of circadian rhythms is linked to conditions such as endometriosis, endometrial cancer, and menstrual disorders.
