In Vitro Fertilization (IVF): Traditional IVF
Carolina Conceptions offers blastocyst culture and transfer, which is a technique developed to maximize pregnancy rates while minimizing the risk of a multiple births.
Typically, an IVF laboratory cultures embryos for about three days. However, with blastocyst transfer our laboratory can grow embryos for five days. After five days of growth, the cells of the embryo should have divided many times over, and have begun to differentiate by function. The embryos (called blastocysts) that survive to this stage of development are usually of the best quality and have an extremely high chance of implantation in the uterus.
This 5-day “extended culture” is made possible by using different culturing media, each one designed to meet the requirements specific to each stage of growth.
Blastocyst culture and transfer allows clinicians to determine with greater certainty, which one or two embryos are the best to transfer to the mother’s uterus for the highest chance of implantation. Since blastocysts have a higher chance of implantation we can transfer fewer embryos, reducing the occurrence of potentially risky multiple births. We encourage younger patients patients (<37 yo) or those who use donor eggs to consider transferring a single embryo, especially if preimplantation genetic screening was performed. Please see the financial options page to learn about the ONE program.
