Blastocyst culture

Blastocyst culture is a laboratory technique in which embryos grow in the laboratory for 5 to 6 days as compared to the usual 2 to 3 days. This extended culture period allows viable embryos to continue development and reach the blastocyst stage of embryo development. The development of nutritive solutions to support embryo growth has greatly improved in the last few years and has led to the clinical application of this technique. The blastocyst stage embryo is a ball of cells approximately 100-150 cells in total.
