Usually, following IVF or ICSI embryo transfer is performed on day 2 or day 3 embryo. Improvements in culture techniques have allowed selective growth of embryos to blastocyst, i.e. embryo age of five or six days. Thus natural selection by leaving embryos in culture for longer time allows selection of more robust embryo with better implantation rate.
