How Does Sex Selection Work?

How does sex selection work? Our Dallas Fertility Specialists have answers.

Couples who long for a child of a specific gender are able to undergo state-of-the-art fertility procedures to ensure pregnancy with either a boy or a girl. Many couples choose family balancing technology because it enables them to honor their cultural backgrounds. It also enables couples who have previously only had children of one gender to enjoy having a child of the other gender. Sex selection involves a process called preimplantation genetic diagnosis (PGD), which is sometimes called preimplantation genetic testing (PGT).

Partial IVF Procedure

PGD begins in the same way as in vitro fertilization (IVF). A female partner will receive medications to stimulate the ovaries to release more eggs. The medications, called gonadotropins, are taken for several weeks. During that time, the woman will receive frequent monitoring to evaluate the maturity of the eggs. Once the eggs are ready, they are retrieved transvaginally via an outpatient procedure. Then, the male partner’s sperm (or donor sperm) is used to fertilize the eggs in a laboratory. Sometimes, this is accomplished with intracytoplastmic sperm injection (ICSI), in which sperm is injected directly into the eggs.

Preimplantation Genetic Diagnosis

After the embryo divides into eight cells, which takes three days, the fertility specialist takes DNA from the cell and uses a polymerase chain reaction (PCR) procedure to copy the DNA. Then, molecular analysis is used to determine whether the embryo is male or female. This process is also used to ascertain whether the embryo contains potentially problematic DNA, which could lead to medical problems for the child.

Embryo Implantation

Once the male and female embryos are separated, an embryo transfer takes place. The embryos that are of the desired sex are implanted into the woman’s uterus.
