Day 5 (or day 6) transfer after in vitro fertilization - blastocyst stage culture and transfer
can maintain high pregnancy rates with very low risk for triplets

4 blastocysts that were "left over" after the embryo transfer
These 5 day old embryos were cryopreserved (frozen) for future use
Hatching mouse blastocyst stained with fluorescent dye
Embryo was cultured on human tubal cells (coculture)
Red-stained cells (trophectoderm) - would become placenta
Blue-stained cells are inner cell mass - fetal cells
- These low quality blastocysts show that blastocyst culture is not a magic bullet for infertility.
- Most human embryos do not have the genetic potential to develop normally to the blastocyst stage, hatch from their shells, implant and continue normal embryonic development in order to result in a live birth.
