Luteal Support and Risk of Ovarian Hyperstimulation in Assisted Reproduction (A Review)
Кубанский научный медицинский вестник, 2020 Background. Gonadotropin-releasing hormone agonist as an ovulation trigger effectively reduces the ovarian hyperstimulation risk in in vitro fertilisation protocols, at the same time requiring an effective luteal phase support in embryo transfer cycles ...

Gonadotrophin releasing hormone agonist with low dose human chorionic gonadotrophin co-triggers versus gonadotrophin releasing hormone agonist alone for reducing the risk of ovarian hyperstimulation in women with polycystic ovarian disease. [PDF]
Al-Azhar International Medical Journal, 2022 Background: “Dual triggering” for final oocyte maturation using acombination of a gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG) can improve clinical outcomes in high responders during in vitro fertilization ...

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.

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 Receptors [PDF]
Endocrine Reviews, 2004 GnRH and its analogs are used extensively for the treatment of hormone-dependent diseases and assisted reproductive techniques. They also have potential as novel contraceptives in men and women. A thorough delineation of the molecular mechanisms involved in ligand binding, receptor activation, and intracellular signal transduction is kernel to ...
