Also knowns as sex selection or family balancing, IVF with Gender Selection gives prospective parents the chance to choose the gender of their offspring. There can be a variety of reasons as to why it might be done.
One reason is the desire of preventing a gender related genetic disease, such as Hemophilia. By choosing the gender, the passing on of the genetic disease can be prevented.
Another reason to proceed with gender selection might be to balance the gender of the already existing offspring.
There are two methods available for the IVF and Gender Selection. One is known as the Microsort technology and the other as the Preimplantation genetic diagnosis (PGD).
Microsort helps enable the separation of the X and Y chromosome sperms. The DNA difference between the X and Y chromosomes helps as the female X chromosomes bear more DNA than the Y chromosome and absorb more dye. The semen is tagged with fluorescent dye that binds to the DNA of the sperm. The female X chromosome will flouresce brighter and they can then be separated.
Pre-implantation genetic diagnosis (PGD) is another method to choose the gender and has generally higher success rates. Also commonly used to determine genetic diseases, the embryos are screened for X and Y Chromosomes so that the embryos of the desired gender can be implanted.
