Does Pre implantation genetic testing have any associated risks

Preimplantation genetic testing (PGT) is the process of evaluating embryos generated during IVF to assess the existence of genetic abnormalities that might lead to pregnancy problems, birth deformities, congenital illness, and/or miscarriage. In circumstances when a parent is in danger of passing on a genetic issue, IVF plus PGT may raise the odds of producing a healthy child.

How is PGT done?

PGT is used to identify a wide range of genetic abnormalities. During PGT, 5-6 blastocyst embryo cells are extracted and submitted to a genetics lab during testing. It is done during the embryonic blastocyst stage, normally after five days following conception, indicating the formation of two kinds of cell masses (one for the fetus and one for the placenta).

Once the embryos’ genetic reports have been completed, the embryos that do not have a hereditary illness or chromosomal abnormalities are recognized and transferred.



What are the different kinds of PGT tests?

When PGT tests embryos for the total number of chromosomes, this is referred to as preimplantation genetic screening (PGS). This kind of testing is currently known as PGT for aneuploidies (PGT-A) and PGT for chromosomal structural rearrangements (PGT-CSR) (PGT-SR). It is a tool for assisting in selecting the best quality and healthiest embryos and avoiding the transfer of those with genetic markers for congenital disorders such as Down syndrome and cystic fibrosis.

Preimplantation genetic diagnosis (PGD) is used when preimplantation genetic testing (PGT) is performed on embryos with known genetic risk. For monogenic/single gene problems, PGD is also known as PGT (PGT-M). This is utilized when testing the parents before an IVF cycle has shown a genetic issue. The embryos are screened for the particular defect and the overall number of chromosomes.

When should you use PGT?

A fertility specialist can assist individuals in making the best selection for their specific scenario. In general, one of the kinds above of PGT should be considered in the following situations:

  • Patients with a known genetic condition or carriers of a genetic disease do not want their kids to be born with that disease.
  • Patients have experienced two or more recurrent miscarriages, particularly if a chromosomal defect caused the losses.
  • Patients who were unable to conceive after a prior IVF treatment.
  • Patients are aged 35 and above want to reduce their risk of miscarriage and the chance of having a chromosomal abnormality diagnosed during pregnancy.
  • For people who desire to have chromosomal screening done to lower their chances of having a miscarriage or chromosomal abnormalities complicate their pregnancy.

Are there any risks in preimplantation genetic diagnosis?

The majority of the dangers associated with PGD therapy are comparable to those associated with standard IVF:

  • Fertility medication reaction: minor responses may include hot flushes, feeling sad or irritated, headaches, and restlessness; symptoms normally resolve quickly.
  • Ovarian Hyperstimulation Syndrome (OHSS): Symptoms include stomach discomfort and swelling, shortness of breath, nausea, vomiting, and a decrease in urine production; may cause mineral imbalances in the blood and coagulation issues.
  • Infection of the uterus.
  • Miscarriage
  • Premature birth

There is presently no compelling evidence to show that kids conceived using this procedure have a higher risk of abnormalities than babies conceived through other kinds of assisted reproduction.
