Neuroendocrine control of gonadotropin‐releasing hormone: Pulsatile and surge modes of secretion

Journal of neuroendocrinology, 2022
The concept that different systems control episodic and surge secretion of gonadotropin‐releasing hormone (GnRH) was well established by the time that GnRH was identified and formed the framework for studies of the physiological roles of GnRH, and later ...

The role of gonadotropin‐releasing hormone neurons in polycystic ovary syndrome

Journal of neuroendocrinology, 2022
Given the critical central role of gonadotropin‐releasing hormone (GnRH) neurons in fertility, it is not surprising that the GnRH neural network is implicated in the pathology of polycystic ovary syndrome (PCOS), the most common cause of anovulatory ...

Luteal-phase support in assisted reproductive technology: An ongoing challenge

International Journal of Reproductive BioMedicine, 2021
It has been shown that in controlled ovarian hyper stimulation cycles, defective luteal phase is common. There are many protocols for improving pregnancy outcomes in women undergoing fresh and frozen in vitro fertilization cycles.
