A prolonged culture of embryos beyond day 2-3 to day 5 (blastocyst culture) after fertilization might be an alternative, simple way of selecting suitable embryos for transfer. Extending embryo culture to day 5/6 is a selection tool to choose an embryo with a greater likelihood of implantation rather than improve embryo quality.
