Blastocyst Transfer

A blastocyst is a human embryo that’s five, six or seven days old.. Most clinicians now believe that transferring better-developed embryos – i.e. those that have reached the blastocyst stage – makes pregnancy more likely, a blastocyst is markedly different to a day-3 embryo. There’s a fluid-filled cavity in the middle called the blastocoel. Another area, housing a dense collection of cells, is called the inner cell mass and will become the fetus. A third assortment of cells, near the central cavity, will form the placenta.

We keep the embryos for observation much longer in the case of blastocyst transfer. This is the process through which we get more possibilities to recognize the embryo or embryos with better implantation probabilities and thereby enhancing the rate of Pregnancy.

Transferring blastocysts can make things more straightforward for implantation. In non-IVF reproduction, a day-2 embryo (usually comprising four cells) will still be rolling down the fallopian tube towards the uterus. Putting a blastocyst directly into the womb on day five or six is an easier prospect for the now highly receptive uterus. Also, genetic testing such as PGD is more accurately carried out on blastocysts.
