In vitro fertilization (IVF) has become one of the most preferred fertility treatments. It offers hope to childless couples by significantly increasing their chances of having children. One of the improvements made in IVF is Preimplantation Genetic Testing (PGT).
PGT involves screening embryos for congenital diseases before implanting them into the uterus. Thus, this technology increases the chances of getting pregnant and giving birth to healthy babies. Knowing how PGD works can help you in choosing the process you will follow to become a parent.
This blog focuses on PGT, its process, and how this new technology has become widespread due to its commendable benefits.
Preimplantation Genetic Testing (PGT) is a secondary technique associated with IVF treatment that allows the genetic characteristics of embryos to be identified. The PGT commences with collecting a few cells from the embryos developed through the IVF method.
Then, the retrieved cells are tested to detect any genetic variations in the developing embryo. This test is performed at an early stage after IVF to identify chromosomal or genetic defects and promote healthy embryos that are most likely to lead to a successful pregnancy.
There are different types of PGT, each serving a specific purpose:
PGT-A (Aneuploidy Test)
PGT-A tests for extra or missing chromosomes (aneuploidies), which might lead to Down’s syndrome. PGT-A is usually recommended for patients who have had multiple IVF failures, a previous or child with specific chromosomal disorders such as Down syndrome, Turner’s syndrome, and Patau’s syndrome.
Although PGT-A may be performed for any IVF cycle, some advantages and disadvantages must be explained by your doctor before deciding on PGT-A for you.
PGT-M (Monogenic Test)
PGT-M process directly looks for certain hereditary metabolic diseases, including cystic fibrosis or Hunter’s disease. By avoiding the transfer of embryos with genetic disorders, patients can give birth to healthy children.
PGT-SR (Structural Rearrangements)
PGT-SR detects chromosomal structural changes, such as translocations or inversions, that could lead to miscarriage or genetic disorders. It helps to identify embryos with balanced chromosomes, reducing genetic risks. A person with structural rearrangements is likely to pass those genes to their children. PGT-SR can detect embryos that effectively lack certain pieces of chromosomes.
The PGT process is carefully integrated after the IVF procedure and is performed under the supervision of experts at the best IVF clinics in Delhi. Here is the step-by-step PGT procedure:
Choosing the best IVF in Delhi might feel exhausting, but before choosing one, always make sure that the clinic provides PGT service. Here are the factors to consider when looking for the best IVF clinic for PGT:
Preimplantation Genetic Testing has revolutionised the IVF process through increased implantation success, decreased miscarriage rates, and a couple’s ability to make better decisions regarding their potential offspring’s genetic makeup.
A PGT may not guarantee a healthy pregnancy but increases the chances of a successful one. Want to join the list of parents who had successful IVF and PGD treatment?
