How it Works

How does Gender Selection Work?

Gender selection uses the same methods as anyone undergoing IVF treatment. Whereby a female's eggs are retrieved and fertilised using their partners, or donor sperm to create viable embryos.

So even if you're not using IVF for fertility issues, it can still be used to choose the child's sex.

All fertilized eggs/ embryos will inherit chromosomes (X & Y) from the parents / donors. It is these chromosomes that determine the sex of the baby, which make sex selection possible. By testing the cells in the embryos, they can determine the gender of the embryo and transfer the embryo with the chosen sex into the uterus.

When transferring the embryo, it's important that the uterus is in optimum condition. This will ensure a successful implantation into the endometrial lining. Therefore it is advised that women take estrogen and progesterone, for a time period prior to the transferal.

Once the embryo has been chosen, for its desired sex, it is thawed out. Once thawed it is implanted in the uterus through a medical grade transfer catheter.
