Chance of having embryos that are ‘competent’ to establish a pregnancy is significantly impacted by a woman’s age. The chance of having embryos with abnormal number of chromosome (aneuploidy) which will result in either no pregnancy or pregnancy loss after transfer is:
To avoid futile transfers or pregnancy loss after IVF treatment, on Day 5 or 6 of culture, our embryologists can take a few cells from each embryo and send the biopsy for genetic evaluation to determine whether the embryo has a normal genetic component.
The cells that are biopsied during PGT are cells that will develop into future placenta. The inner cell mass that will develop into the fetus remains intact during the PGT process. Only 5-6 cells are removed for genetic testing and PGT is considered a safe technology. That being said, there is a very small chance that removing a cell from the embryo could damage the embryo. Think Fertility has a team of embryologists who have extensive experience and high skills of embryo biopsy. The chance of embryo damage from biopsy and PGT is < 1 %.
Yes. The sex of embryos can be identified by PGT and only the healthy embryos of the desired sex will be transferred.
