The effect of intracytoplasmic sperm injection (ICSI) on the timing of embryonic progression in cycles where oocytes were split into both ICSI and conventional insemination

Abstract

To assess whether timing of blastulation was altered between oocytes that were fertilized with conventional insemination versus intracytoplasmic sperm injection (ICSI). To also evaluate the differences in fertilization rates (FR), overall blastulation rates (BR) and pregnancy rates (PR).
