Analysis of Embryo Scoring and Comparison of Clinic Performance in In-Vitro FertilizationWhistler, James W 01 May 2015 (has links) (PDF)
Clinical Assisted Reproductive Technology (ART) practices seek to make improvements in embryo quality and resultant procedural success rates. There is a significant variance in live birth rates among clinics nationwide. The goal of this thesis is make comparisons of embryo quality among clinics and understand these differences. This analysis focuses on the stage between egg retrieval and embryo transfer. Because the currently accepted embryo scoring methods are not directly proportional to performance, a new scoring methodology is proposed and applied. Data provided by the Society for Assisted Reproductive Technology (SART) consisting of 36,836 patient cycles from 40 anonymous clinics nationwide is considered. After necessary reductions are made, the data is anatomized to link each embryo transferred to an implantation probability. A score is generated for each morphology grouping based on the average implantation rate of that group. This score is used as the basis for clinic comparisons. Top-performing clinics (in terms of live birth rates in patients agedold) are then shown to both produce embryos of higher score and achieve better results from embryos of identical morphology.

A prospective randomized study to compare Nidoil and Ovoil cultur oils used to culture human embryos in IVF therapyDoyo, Kader January 2016 (has links)
Background: Since the initiation of assisted reproduction techniques, several studies has been performed to improve treatment results by development of culture conditions like embryo oil and culture media used. In this study, two embryonic oils from different companies, Nidoil and Ovoil were examined.Method: In this study, 47 human embryos were used. All embryos were donated for research purposes by couples who had been treated at the clinic in Uppsala University Hospital. The embryos were divided into two groups, one group was cultured with Ovoil and the other with Nidoil.Results: There was no difference between the two oils, the embryo quality was the same in both groups.CONCLUSION: The result was expected because both oils had the same composition and purity.
