One of the leading economists of his generation both in the U.S. Career įarhi started his career in the Economics department of Harvard in 2006 and was tenured in 2010. He received tenure four years later when he was named a full professor. That same year he began working at Harvard as assistant professor in the Faculty of Arts and Sciences. He finished his studies at the Massachusetts Institute of Technology (MIT) and was awarded a Ph.D. He was then admitted to the Corps des Mines in 2001. He specialized in Mathematics obtaining 2nd place on the Agrégation de Mathematiques (French degree). Ranking 1st on the national entry exam to the elite engineering school École Polytechnique in 1997, he eventually chose to attend another prestigious French graduate school, École Normale Supérieure. At age 16 he won the Concours général in Physics and continued on to study Mathematics in preparatory class. The son of an economist of Egyptian Jewish descent, Farhi grew up in Paris where he attended the Lycée Louis-le-Grand. He was a member of the French Economic Analysis Council to the French Prime Minister from 2010 to 2012. His research focused on macroeconomics, taxation and finance.

IVF cycle segmentation freeze-all frozen embryo transfer ovarian stimulation systematic review. Optimisation of ovarian stimulation for freeze-all cycles should result in enhanced treatment safety along with improved cumulative live birth rates and should become the focus of future studies. Ovarian stimulation for freeze-all cycles is different in many aspects from conventional stimulation for fresh IVF cycles. There is conflicting evidence regarding the effect of late follicular progesterone elevation in freeze-all cycles. However, no significant adverse effects have been described. There are no high-quality studies evaluating the effects of sustained supraphysiological estradiol (E2) levels on the safety and efficacy of freeze-all cycles. Moderate-quality evidence indicates that in freeze-all cycles, a moderate delay of 2-3 days in ovulation triggering may result in the retrieval of an increased number of mature oocytes without impairing the pregnancy rate. The addition of low-dose hCG in a dual trigger has been suggested to improve oocyte and embryo quality, but further research in freeze-all cycles is required. Ovulation triggering with a GnRH agonist almost completely eliminates the risk of OHSS without affecting oocyte and embryo quality and is therefore the trigger of choice. The improved safety associated with the GnRH antagonist regimen makes it the regimen of choice for ovarian stimulation in freeze-all cycles. The early follicular phase is currently the preferred starting point for ovarian stimulation, although luteal phase stimulation can be used if necessary. Therefore, ovarian stimulation should be planned to yield between 15 and 20 oocytes. Although the risk of severe ovarian hyperstimulation syndrome (OHSS) is virtually eliminated in freeze-all cycles, there are certain risks associated with retrieval of large oocyte cohorts. Good-quality evidence indicates that in freeze-all cycles the cumulative live birth rate increases as the number of oocytes retrieved increases. Overall, 69 articles were included in the final review. We included relevant studies published in English from 2000 to 2018. The search strategy included keywords related to freeze-all, cycle segmentation, cumulative live birth rate, preimplantation genetic diagnosis, preimplantation genetic testing for aneuploidy, fertility preservation, oocyte donation and frozen-thawed embryo transfer. We aimed to conduct a systematic review of all aspects of ovarian stimulation for freeze-all cycles.Ī comprehensive search in Medline, Embase and The Cochrane Library was performed. However, the actual treatment objectives and preferred treatment regimens for freeze-all cycles have not been clearly established. Freeze-all IVF cycles are becoming increasingly prevalent for a variety of clinical indications.
