Official title
Use of GnRH Antagonist (Cetrotide) Protocol, Instead of Agonist, to Prepare Recipients for Embryo Transfer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
26% of all ART cycles performed in the USA in 2003 (CDC data) are frozen embryo transfers (FET) and transfer of embryos resulting from egg donation (ED) to recipients. The typical protocol used to prepare a recipient for ET involves GnRH agonist (Lupron, Tap Pharmaceuticals) to down regulate the patient. A GnRH antagonist, such as Cetrotide (EMD Serono), is comparable to GnRH agonist and FDA approved to prevent spontaneous ovulation with ART treatment, and its usage decreases significantly the number of injections that the patient receives with treatment. The working hypothesis for this study is that the GnRH antagonist (Cetrotide) can be used instead of an agonist to achieve effective down regulation in FET and ED cycles. Presumably, patients will prefer Cetrotide over Lupron because of the markedly fewer injections required.
