Preimplantation genetic testing

Effectiveness, Procedure and Associated Complications

If your family has a hereditary genetic disease, you may want to look into ways to lessen the chance of transmitting the condition to your child. As a result, your fertility doctor may discuss PGD testing with you. Many medical procedures, on the other hand, might make patients feel unsure and frightened. The essential facts about Preimplantation genetic testing are described in detail below. With this knowledge, you and your spouse will be able to obtain a better understanding of IVF and PGD techniques, allowing you and your partner to feel more confident and empowered as you begin the process.

About Preimplantation genetic testing

Preimplantation genetic testing is a laboratory method that allows couples to evaluate embryos prior to implantation in order to reduce, but not entirely eliminate, the risk of having a baby with certain genetic disorders. People with a genetically inherited ailment in their family can use preimplantation genetic diagnostic (PGD) to avoid passing it on to their descendants.

The procedure of Preimplantation genetic testing

An IVF cycle involves retrieving the mother's eggs and fertilizing them with sperm. Embryos have roughly 8 cells after three days of growth, and by five days, many embryos have more than 100 cells. Preimplantation genetic testing is a procedure that removes one or more cells from a growing embryo using sophisticated microsurgical lasers and microscopes. These cells are tested at one of the country's top genetics labs, and a genetic analysis identifies which embryos are best for uterine transfer. This is a lengthy procedure that is tailored to each patient's unique circumstances. Therefore, the type of genetic evaluation performed and even the stage of embryonic development at which the biopsy is performed is not constant from patient to patient.

The associated complications

Misdiagnosis is the greatest danger of all methods of  Preimplantation genetic testing The main danger stems from a process known as "mosaicism," which has been observed in embryos. Mosaicism occurs when a single embryo contains numerous different types of cell lines. In other words, mosaicism occurs when a component of an embryo's cells is normal but another portion is defective. This could lead to inaccuracies in preimplantation testing results, such as failing to diagnose faulty embryos or incorrectly categorizing abnormal embryos as normal.

The success rate

IVF does not always result in pregnancy, as many hopeful parents are aware. The chances of conception are driven by a range of factors, all of which are unique to your situation. If you want to know more about your chances of conceiving with IVF + PGD, talk to your doctor in detail and ask for pregnancy rates statistics. In the vast majority of situations, PGD testing is 100% accurate. As a result, doctors advise confirming  Preimplantation genetic testing results during pregnancy.
