Early Morphokinetic Monitoring of Embryos after Intracytoplasmic Sperm Injection with Fresh Ejaculate Sperm in Nonmosaic Klinefelter Syndrome: A Different Presentation

The patient was diagnosed with nonmosaic 47, XXY Klinefelter Syndrome with the AZF deletion absent and SRY+. The nonmosaic 47, XXY karyotype was confirmed on a skin biopsy chromosomal analysis. Using only ejaculate motile sperms, 11 oocytes underwent ICSI and were placed rapidly in a time lapse (Embryoscope ©) with a specific culture dish. Biopsies were performed on six embryos on the 3rd day, and numerical chromosomal abnormalities were observed using the FISH test before transfer. PGS results were normal in only two embryos with normal morphokinetics in the Embryoscope. For clinical confirmation of pregnancy, ultrasonographic examination was performed during the 7th week of pregnancy, and two gestational sacs and fetal heart beat were observed

Gonadotrophin-releasing hormone agonist trigger and freeze-all strategy does not prevent severe ovarian hyperstimulation syndrome: a report of three cases

Ovarian hyperstimulation syndrome (OHSS) is the most serious iatrogenic complication of IVF cycles. Although the development of effective treatment strategies for this syndrome is important, preventing OHSS is more crucial. Triggering ovulation with a gonadotrophin-releasing hormone (GnRH) agonist is one method used to avoid OHSS. In this paper, three patients who developed severe OHSS after undergoing GnRH agonist triggering and freezing of all embryos in a GnRH antagonist protocol are described. A review of the literature is also provided. This report highlights the ongoing risk of severe OHSS even after GnRH agonist triggering combined with freezing all embryos in GnRH antagonist cycles. Other prevention strategies might be considered for extreme hyper-responders. (C) 2014 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved

GnRH agonist triggering affects the kinetics of embryo development: a comparative study

Background: To evaluate the effects of an ovulation triggering agent, human chorionic gonadotropin (hCG), versus a gonadotropin-releasing hormone agonist (GnRHa) on early embryo development in vitro using a time-lapse system. Methods: Retrospective analysis of a prospectively collected database. A total of 739 embryos from 152 infertile couples undergoing intracytoplasmic sperm injection cycles. Interventions : Embryo culture in a time-lapse incubator (EmbryoScope, Vitrolife, Goteborg, Sweden). Main Outcome Measures: Embryo morphokinetic parameters. Results: In the 152 women, 252 embryos were derived from GnRHa-triggered cycles compared with 487 embryos derived from hCG-triggered cycles. Time-lapse analysis revealed that embryos from cycles triggered by a GnRHa cleaved faster than embryos derived from hCG-triggered cycles. Conclusion: Triggering with a GnRHa in in vitro fertilization cycles affects embryo kinetics
