In vitro oocyte maturation
A study for the relation among morphokinetic parameters, mitochondrial pattern and karyotype for better selection of embryos undergoing in vitro maturation
A study for the relation among morphokinetic parameters, mitochondrial pattern and karyotype for better selection of embryos undergoing in vitro maturation
The aim of this study is to investigate the relations among morphokinetic parameters, mitochondria patterns and karyotype in order to decrease both the implantation failure rate and miscarriage rate of IVM embryos. The primary outcome of this study is to utilize the immature oocytes to increase the number of available embryo for improving the success rate of IVF by identifying the cytogenetic abnormal embryo through morphokinetic parameters. The second outcome is that we can increase our knowledge of meiotic error by studying the morphokinetic parameters and karyotype of immature oocytes.
