Gender Selection

What is Gender Selection?

Gender SelectionSex or gender selection is the ability to choose the gender or sex of your child before you become pregnant. Two chromosomes, namely the X and Y chromosomes, determine the sex of your child. One is inherited from the mother and one is inherited from the father.

The egg from the mother carries an X chromosome and the sperm from the father carries either an X or a Y chromosome. If the egg is fertilized with an X- bearing sperm, the resulting XX embryo will be female. If the egg is fertilized by a Y- bearing sperm, the resulting XY embryo will be male.

Typically, there is a 50/50 chance of conceiving either a female or a male child. In vitro fertilization (IVF) in conjunction with Preimplantation genetic diagnosis (PGD) and blastocyst biopsy can predict with an almost 100% accuracy the sex of the child prior to performing the embryo transfer.

Who Would Benefit From Gender Selection?

There are two primary reasons for considering gender selection:

Genetic Disease: Some couples have certain genetic diseases that they do not want to pass on to their children. Examples of X-linked diseases that would result in male children being affected include hemophilia and muscular dystrophy. In these cases couples choose to have a female child.

Family Balancing: Couples who already have a child of one sex may turn to fertility treatment to have another child of the opposite sex. Conversely, there may be cultural reasons for having a child of a specific gender.
