GnRH agonist versus GnRH antagonist in ovarian stimulation: an ongoing debate

open access: yesReproductive BioMedicine Online, 2013
The availability of gonadotrophin-releasing hormone (GnRH) antagonists for ovarian stimulation protocols has generated many meta-analyses comparing it to GnRH agonist long protocols. These meta-analyses have yielded conflicting results for pregnancy rate,

Serum levels of antimüllerian hormone in early maturing girls before, during, and after suppression with GnRH agonist

open access: yesFertility and Sterility, 2012
To evaluate whether serum antimüllerian hormone (AMH) levels are affected in early maturing girls, and whether pituitary suppression by long-acting GnRH agonist (GnRH-a) affects ...

GnRH agonists vs antagonists

Best Practice & Research Clinical Obstetrics & Gynaecology, 2007
Gonadotropin-releasing hormone (GnRH) agonists were introduced in ovarian stimulation for in-vitro fertilization to suppress the premature surge of luteinizing hormone (LH). Although agonist use is accompanied by a series of disadvantages, including hypoestrogenaemia, cyst formation, a requirement for a prolonged period of downregulation, and an ...

Safety of GnRH agonists and antagonists

Expert Opinion on Drug Safety, 2004
The widespread application of protocols using gonadotropin-releasing hormone (GnRH) agonists or antagonists in assisted reproduction treatment has led to an increasing number of pregnancies exposed to these drugs. This issue has raised scepticism as to the safety of these medications, concerning both pregnant women and their offspring.

GnRH Agonists

Clinical Obstetrics and Gynecology, 1989
The development of GnRH agonists has had a major impact on the practice of gynecology and reproductive endocrinology. The clinical usefulness of GnRH agonists will increase as modes of administration are improved and indications become better defined. GnRH agonists and, potentially, antagonists will provide a prompt, effective, and reversible method of

Uses of GnRH Agonists

Journal of Obstetric, Gynecologic & Neonatal Nursing, 1994
Gonadotropin-releasing hormone agonists are a relatively new class of drugs, which, when chronically administered, result in marked reductions in blood levels of testosterone and estrogen. These drugs include leuprolide acetate (Lupron); the first GnRH agonist to be approved in the United States, nafarelin acetate (Synarel); and goserelin acetate ...

GnRH Agonists and Antagonists

Drugs, 1988
Gonadotrophin-releasing hormone (GnRH) analogues offer a novel approach for the non-steroidal manipulation of the reproductive endocrine axis. GnRH agonists are now effectively employed in the management of precocious puberty, prostate and breast cancer, endometriosis, uterine leiomyoma, polycystic ovarian disease, and various other disorders ...

GnRH-agonists in fertility preservation

Current Opinion in Endocrinology, Diabetes & Obesity, 2008
Description of the recent progress in fertility preservation despite gonadotoxic chemotherapy, using gonadotropin-releasing hormone (GnRH)-agonists (GnRH-a).Most groups of investigators have found a beneficial effect of the administered GnRH-a on minimizing the chemotherapy-associated gonadotoxic effect, in both hematologic diseases, mainly Hodgkin ...

GnRH Agonist Protocols

2020
In vitro fertilization, commonly referred to as IVF, is a procedure in which infertility of varied etiologies is overcome. The current standard of care requires ovaries to be sufficiently stimulated to allow the collection of many oocytes, which are then fertilized in the laboratory and eventually transferred to a receptive uterine cavity.
