Virtually every eukaryotic cell has an endogenous circadian clock and a biological sex.
These cell-based clocks have been conceptualized as oscillators whose phase can be reset …

Precise timing in hormone release from the hypothalamus, the pituitary and ovary is critical
for fertility. Hormonal release patterns of the reproductive axis are regulated by a feedback …

Ovarian steroids normally exert homeostatic negative feedback on GnRH release. During
sustained exposure to elevated estradiol in the late follicular phase of the reproductive cycle …

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 …

Gonadotropin hormone-releasing hormone (GnRH) is the key regulator of the reproductive
axis. Its pulsatile secretion determines the pattern of secretion of the gonadotropins follicle …

Simple Summary In mammals, circadian rhythms in nearly all behaviors and physiological
processes are controlled by the suprachiasmatic nucleus, a collection of neurons in the …

A minimum amount of energy is required for basic physiological processes, such as protein
biosynthesis, thermoregulation, locomotion, cardiovascular function, and digestion …

This article is an amalgamation of the current status of RFRP-3 (GnIH) in reproduction and
its association with the nutrition and stress-mediated changes in the reproductive activities …

Circadian rhythms are~ 24 h cycles of behavior and physiology that are generated by a
network of molecular clocks located in nearly every tissue in the body. In mammals, the …

Gonadotropin-releasing hormone (GnRH) neurons are critical to controlling fertility. In vivo,
estradiol can inhibit or stimulate GnRH release depending on concentration and …
