Sperm Sorting for Gender Selection

Sperm sorting for gender selection is not a preferred method at our New York fertility center

When researching gender selection, prospective parents may hear about “sperm sorting” as a way to improve the odds of having a baby of a specific gender. In part because sperm sorting is not approved by the U.S. Food and Drug Administration for use in the United States, our New York fertility center instead offers preimplantation genetic screening with IVF for patients who wish to predetermine the sex of their babies.

Sperm sorting for gender selection is a technique that separates sperm bearing the X chromosome from those bearing the Y chromosome. Then, patients hoping to have a girl (XX chromosomes) can elect to use the batch of primarily X chromosome-bearing sperm for intrauterine insemination or IVF, while patients aiming for a boy (XY chromosomes) can choose to use the batch of primarily Y-chromosome bearing sperm.

While sperm sorting for gender selection does claim to improve the odds of having a baby of the desired sex, it is not as effective as gender selection through PGS, which is virtually 100% accurate in determining an embryo’s sex.

PGS is more reliable

Preimplantation genetic screening at our New York fertility center is a much more reliable method of gender selection.

To take advantage of this technique, patients first participate in an in vitro fertilization cycle in which our fertility specialist, Dr. Joel Batzofin, retrieves eggs for fertilization in our lab.

The resulting embryos spend several days growing; then, expert embryologists extract a group of cells from each and send these to a reference lab. The embryos are then flash-frozen while we wait for results. Testing will identify genetic abnormalities and chromosomal balance. When the parents are ready to transfer an embryo to the woman’s uterus, only genetically normal embryos of the parents’ preferred gender are selected.

This method is almost 100% reliable in ensuring that the baby will be a boy or a girl, making PGS an ideal choice for parents who wish to choose their baby’s gender for medical reasons or family balancing.

When a sperm with a Y chromosome fertilizes an egg, it makes a boy.

When an X chromosome bearing sperm fertilizes, it makes a girl.
