Embryo Freezing, additional opportunities for success
Embryo freezing, also known as cryopreservation, is just one of the effective treatment options available at Western Fertility Institute. Freezing embryos adds an important component to assisted reproduction – allowing the process of selecting, freezing, and storing embryos for later use.
Some patients may have excess embryos which may provide them with another chance for pregnancy without having to go through another ovarian stimulation and egg retrieval. Freezing of the additional embryos provides an opportunity to achieve pregnancy at a later date, increasing the number of potential transfers from a single retrieval. The chances of becoming pregnant with a frozen embryo are not affected by the length of time the embryo has been stored.
Another important component to embryo freezing is the ability to do genetic testing, preimplantation genetic diagnosis (PGD) – testing for genetic conditions and genetic mutations. In addition, embryo freezing allows preimplantation genetic screening (PGS). PGS testing looks for chromosomal abnormalities.

What is Sex Selection?
It is common for many patients to be curious about the ability to choose the sex of their baby. This is known as Sex Selection (also commonly referred to as Gender Selection). Through genetic testing, this is possible for our patients undergoing IVF at Western Fertility Institute. A By-product of the genetic testing performed on the embryos called PGT-A allows for differentiation between male and female embryos since the sex of each embryo is identifiable by their chromosomes.
How does Sex Selection Work?
Sex selection through Preimplantation Genetic Testing for Aneuploidy (PGT_A) testing allows patients to select the sex of their embryos with almost 100% accuracy. Our highly skilled embryologists will biopsy a single cell from the embryo and send it to a third-party laboratory for PGT-A testing. The PGT-A results will show if each embryo has the proper number of chromosomes as well as the prospective of sex. Embryos containing two X chromosomes are female, while male embryos will contain one X and one Y chromosome. This allows the patient to choose a PGT-A embryo of a desired sex for transfer.
Why Do People Use Sex Selection?
Patients choose to use sex selection as an option for multiple reasons. In some cases, it can be used for medical reasons. Sex selection allows for the prevention of sex-linked genetic diseases and chromosomal disorders. For instance, there are certain disorders, linked to the X or Y chromosomes, that have the potential to be passed on to only a son or only a daughter. In other cases, sex selection can be used for what is known as "family balancing". Family balancing is when the patient chooses a specific sex in order to fulfill their desire of a balanced family. This can include choosing a sex based on a previously lost child, because they feel better equipped to raise a specific sex, or they want representation of both sexes in their family.
