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.

Clinical applications of gonadotropin-releasing hormone analogues: a broad impact on reproductive medicine

F&S Reports, 2023
Gonadotropin-releasing hormone (GnRH) is central to the control of the entire hypothalamic-pituitary-gonadal axis. Manipulation of GnRH, in turn, regulates pituitary response and ovarian hormone production.

A regulator of G Protein signaling, RGS3, inhibits gonadotropin-releasing hormone (GnRH)-stimulated luteinizing hormone (LH) secretion

BMC Cell Biology, 2001
Background Luteinizing hormone secreted by the anterior pituitary gland regulates gonadal function. Luteinizing hormone secretion is regulated both by alterations in gonadotrope responsiveness to hypothalamic gonadotropin releasing hormone and by ...

Induction of final oocyte maturation in Cyprinidae fish by hypothalamic factors: a review

Veterinární Medicína, 2009
Gonadotropin-releasing hormone in Cyprinidae as in other Vertebrates functions as a brain signal which stimulates the secretion of luteinizing hormone from the pituitary gland. Two forms of gonadotropin-releasing hormone have been identified in cyprinids,

Gonadotropin-Releasing Hormone Receptor

Definitions, 2020
GnRHplays a critical role in regulating mammalian reproductive development andfunction. At the level of the anterior pituitary, GnRH binds to the GnRH receptor (GnRHR) on the cell surface ofpituitary gonadotropes.
