What is Gender Selection?

Gender Selection by Preimplantation Genetic Diagnosis is a genetic test that can be performed on the embryos during an IVF treatment and allows to detect the chromosomal gender of the embryos (XX or XY) before they are implanted in the womb. The test also allows us to detect aneuploidies related to sex-chromosomes (such as monosomy X related to Turner syndrome, Trisomy XXY related to Klinefelter syndrome, etc).

How is it performed?

  1. In Vitro Fertilization cycle to obtain embryos performed in an Assisted Reproduction unit.
  2. Embryo Biopsy: it is performed on day 3 embryo development and consists of removing one cell from the embryo without compromising its normal development.
  3. Genetic Diagnosis: the cell obtained from the embryo is processed for genetic analysis by PGDlabs team. The test is performed by FISH and allows us to determine the sex-chromosomal dotation of the embryo.
  4. Embryo Transfer. The results of the genetic test are transmitted to the assisted reproduction unit and the normal embryos of the desired chromosomal gender are transferred.

Who can benefit?

Gender Selection by PGD can be offered to couples for family balancing purposes or for medical reasons to prevent sex-linked genetic disorder, especially when the genetic cause (mutation) has not been definitively stablished.
