During a fertility treatment, one of the most important and most commonly misunderstood terms is blastocyst. But… what does it really mean, and why is it so important?
A blastocyst is an advanced stage of embryonic development. After the egg is fertilized by the sperm, the embryo begins dividing and growing day by day until it reaches, usually on day 5 or 6, this stage where it already contains hundreds of cells.
At this point, the embryo has already started differentiating the cells that will later form the baby and the placenta.
Why are blastocysts so important?
Blastocysts often have higher chances of implanting in the uterus and achieving a successful pregnancy, since reaching this stage is a sign of good embryonic development.
In addition, transferring blastocysts allows:
Selection of embryos with better development
Better synchronization with the uterus
Higher chances of pregnancy
Reduced need to transfer multiple embryos
Do all embryos reach the blastocyst stage?
Not always, and that can be completely normal.
During the first few days, some embryos stop developing while others continue evolving properly until they reach the blastocyst stage.
The number obtained may vary depending on factors such as:
Age
Egg quality
Sperm quality
Response to treatment
Much more than cells
Behind every blastocyst there is science, hope, and the dream of building a family. ✨
At Ventris, every embryo is carefully monitored in the laboratory to provide the best possible opportunities for our patients.
