Blastocyst Transfer

Blastocyst Transfer

After an egg is fertilized and the resulting embryo develops for about five to six days, it reaches the blastocyst stage of development. At this stage of embryonic development, the embryo will consist of two distinct types of cells, the embryoblast and trophectoderm, as well as a central fluid-filled cavity. The embryoblast refers to the inner cell mass of the blastocyst that will eventually develop into the fetus. The trophectoderm refers to the outer cells that surround the fluid-filled cavity and inner cell mass that will later develop into the placenta. On the sixth day of development, the blastocyst emerges from its outer shell and, within the next 24 hours, will embed itself into the uterine wall.

What Happens During Blastocyst Transfer?

Following egg retrieval and in vitro fertilization (IVF), embryos are grown to the blastocyst stage. The blastocysts can be genetically tested (Preimplantation Genetic Testing, or PGT), and can be transferred fresh or after freezing and thawing. The embryo transfer is timed to when the uterus is most receptive, days after ovulation in a natural cycle or after progesterone supplementation in a synthetic cycle.

At RMA of New York at CareMount, precise timing and performance of blastocyst transfer is a core component of a successful IVF cycle.

In the past, embryo transfers were performed on the second or third day after fertilization, which is earlier than an embryo would naturally enter the uterus after being fertilized in the fallopian tube. However, thanks to recent advances in laboratory technology and culture conditions, we are able to delay the transfer until five or six days after fertilization. This means that the transfer can occur during a more “natural” time for conception. Additionally, culturing embryos to a later stage of development allows for the identification and selection of the best quality embryo for transfer, increasing pregnancy success rates, while reducing the risk of multiple pregnancy.
