Knowing the gender of the embryo before transfer to the gestational carrier is possible.
In fact, this technique is commonly used to avoid the transmission of hereditary diseases linked to sex chromosomes and is included in Preimplantation Genetic Diagnosis (PGD).
PGD provides information about the chromosomal constitution of embryos. Its main application is to select a "chromosomally healthy" embryo. Also, since this technique allows the analysis of all the embryo's chromosomes, it is possible to know if it is XX or XY (female or male).
Biopsy is usually performed on five or six-day embryos. At this stage of development, the embryo is called a blastocyst and is composed of an inner cell mass and an outer layer of cells called trophoectoderm. The inner cell mass will later become the fetus, while the cells of the trophoectoderm will become the placenta. Biopsies are taken from the trophoectoderm, but the cells that will form the baby are left intact and are not at risk.
In case of pregnancy, the success rate in obtaining the chosen gender is 100%, as the transfer was made with this information.
In our first surrogacy experience, we did not have the opportunity to learn this information about the biopsied embryos, as the surrogacy center only provided this report to those who opted for the VIP plan, which was much more expensive for families.
However, in our second process, all families received this information without distinction and could choose whether or not to define the gender of the blastocysts that would be transferred to the gestational carrier.
This is an aspect to consider in your choice of the surrogacy center. Count on us if we can help you on this surrogacy journey.
