PGD And PGS In IVF Treatment

Nowadays, with advancements in technology in the medical field, it has become easier for couples to solve their infertility issues. IVF treatment done in an IVF Centre in Punjab is now one of the most sought answers for such a situation. It is a safe and successful technique that eliminates any kind of complication.


One such complication that the doctor reduces at the time of IVF treatment is the chances of genetic abnormalities being passed down by the embryo. The Best IVF Doctor in Ludhiana advised their patients to undergo specific tests before moving ahead with the embryo transplant phase. Two examinations dictate which embryo would be best with no genetic abnormalities for the stage of implantation. Those two tests are PGS (Preimplantation Genetic Screening) and PGD (Preimplantation Genetic Diagnosis). After these tests, the doctor only chooses the embryo free of any genetic abnormalities for the implantation in the woman’s uterus.


What Is PGD (Preimplantation Genetic Diagnosis)?

PGD is a genetic screening that helps the doctor detect the embryo’s genetics, which has certain diseases in it. Either the man or the woman, if any of them had a genetic or family history of a medical condition, this screening helps diagnose the embryo with similar attributes. This makes it easier for the doctor to choose an embryo free of such issues so that the genetic medical condition does not pass on.


Some of the diseases that PGD might diagnose are:


  1. Huntington’s Disease
  2. Marfan Syndrome
  3. Cystic Fibrosis
  4. Duchenne Muscular Dystrophy
  5. Hemophilia
  6. An abnormal number of chromosomes
  7. Exchange of chromosomes material that may lead to mental retardation, miscarriage, and birth defects


What Is PGS (Preimplantation Genetic Screening)?

PGS is a technique that decides whether the cells found in the embryo have the correct number of chromosomes in it or not. In general, human beings carry around 23 pairs of chromosomes in them.


IVF’s biggest risk is that it can have multiple pregnancies. To maximize the chances of a successful pregnancy, the doctor implants 2-3 embryos in the uterus. But if you undergo genetic screening, it would help reduce such risk as the doctor might choose the right embryo for implantation. PGS helps detect an embryo with the right amount of chromosomes; it reduces the chances of a failed pregnancy. This is done because one of the biggest reasons for miscarriages or embryo implantation failure is due to having more or less a number of chromosomes.


As the woman grows older, the risk of having abnormal amounts of chromosomes increases. This is why most of the time, this test is recommended for women who are older than 35 years old and are using IVF treatment to conceive a child. It is also suggested to a woman who has had recurrent miscarriages.


What Is the Difference between PGS and PGD?

As compared to PGD, which is a complicated examination, PGS is known for being a simple test that determines specific diseases. PGS could also be used to diagnose down syndrome by checking the embryo. This disease is caused by extra chromosomes found in the human DNA known as Trisomy 21.
