Overview
Brief Summary
Nowadays, the rapid development of human assisted reproductive technology (ART) has provided many help for couples with fertility issues. Even take baby home rate has been increased dramatically in the past several decades; both clinicians and embryologists are still struggling to improve pregnancy rates. Among all the strategies that the embryologists have tried, much work has been done to find better embryo culture conditions and embryo quality evaluation system. Currently, most centers in the world, including ours, are still using conventional incubators and manual embryo scoring system. This traditional method has several limitations, such as unstable environment during culture, and embryo scores can be different judged by different embryologists. EmbryoScope® by Vitrolife is a newly developed time-lapse embryo culture and analysis system. It is user-friendly, and suited for routinely daily use. In addition, its KID Score system can help embryologist select high quality embryos quickly, which leads to an overall increase in pregnancy outcome in IVF/ICSI cycles. The aim of this prospective cohort study is to evaluate the use of EmbryoScope® in our center.
Detailed Description
All patients included into this study are divided into three groups: 1. Time-lapse-Auto: All embryos are cultured in EmbryoScope®; embryo scores are evaluated on day 3 by KID Score system. 2. Time-lapse-Manual: All embryos are cultured in EmbryoScope®; embryo scores are evaluated on day 3 by embryologist. 3. Conventional Group: All embryos are cultured in our daily used incubators; embryo scores are evaluated on day 3 by embryologist. The aim is to compare IVF/ICSI outcomes, such as pregnancy outcome, fertilization rate, cleavage rate, high quality embryo rate, blastocyst formation rate, among these three groups.
