PGD Tijuana (preimplantation genetic diagnosis) is a procedure that allows couples with a hereditary genetic condition to significantly reduce the risk of passing it onto their children. In many cases, PGD Tijuana can help prospective parents prevent their baby from being born with a serious genetic condition.
PGD testing in Tijuana is utilized during an in vitro fertilization or IVF cycle. Below, we explain IVF with preimplantation genetic diagnosis in more detail, so prospective parents can get a clearer picture of how it works.
How is PGD Tijuana Performed?
PGD Tijuana is performed as part of the IVF process. For all couples the following steps will be performed:
- Female partner takes medications to stimulate the ovaries to make multiple eggs grow
- Eggs are retrieved with a transvaginal needle in an office procedure
- Eggs are fertilized by sperm using a process called ICSI
- Embryos develop in the embryology laboratory over the course of 5-6 days
On day 5 or 6 of development, when embryos have reached the blastocyst stage, a few cells that would eventually become placental cells are removed from the outer layer of the embryo (this is called a trophectoderm biopsy). The cells are then sent to a special laboratory that will test for the specific abnormality in question using the most advanced techniques.
The embryos are frozen immediately, using vitrification. When the results are returned, normal embryos can be thawed and placed back in the uterus in a subsequent frozen embryo cycle.
Of the embryo(s) that are not affected by the genetic disorder or chromosomal abnormality, the best quality embryo(s) are selected for transfer to the uterus. If additional unaffected and good-quality embryos are available, they may remain cryopreserved for a future embryo transfer.
Is PGD Testing Successful?
As many prospective parents know, IVF does not always result in pregnancy. Many factors affect the chances of conception, all of which depend on your individual circumstances. If you want to better understand your chances of conceiving with IVF Tijuana + PGD Tijuana it is important to have a detailed conversation with your physician and ask for data on pregnancy rates.
PGD testing is 98% accurate in most cases. Therefore, doctors recommend confirmatory testing during pregnancy to establish the results of PGD. Testing during pregnancy has an even higher accuracy than PGD for single gene conditions.
PGD Tijuana and PGS are now being replaced by new terminology of Preimplantation Genetic Testing (PGT).
