A fundamental principle in reproductive neuroendocrinology is sex steroid feedback: steroid
hormones secreted by the gonads circulate back to the brain to regulate the neural circuits …

Fertility in mammals is ultimately controlled by a small population of neurons–the
gonadotropin-releasing hormone (GnRH) neurons–located in the ventral forebrain. GnRH …

Coordinated fluctuations in female reproductive physiology and thermoregulatory output
have been reported for over a century. These changes occur rhythmically at the hourly …

Objective To investigate the associations between sleep behaviors and female infertility.
Methods We conducted a cross-sectional study composed of 2175 US women 18-44 years …

Both the circadian clock and sex hormone signaling can strongly influence brain function,
yet little is known about how these 2 powerful modulatory systems might interact during …

Circadian rhythms are endogenously generated, daily patterns of behavior and physiology
that are essential for optimal health and disease prevention. Disruptions to circadian timing …

Background The suprachiasmatic nucleus (SCN) within the hypothalamus is a key brain
structure required to relay light information to the body and synchronize cell and tissue level …

Objectives This systematic review and meta-analysis study aimed to examine the
relationship between infertility and sleep quality in women. Methods The literature search …

This narrative review explores the relationship between psychological stress and ovulatory
disorders, focusing on the molecular mechanisms involved. Ovulation is regulated by the …

Jet lag and shift work disrupt the menstrual cycle and decrease fertility. The circadian
pacemaker, the suprachiasmatic nucleus (SCN), is known to modulate ovulation, but the …
