Preimplantation genetic testing for Aneuploidies (PGT-A) is a test to detect chromosomal abnormalities an is one of the most important tests that is carried out in IVF or ICSI before the embryos are returned to the mother's womb. When an egg is fertilized with a sperm artificially, the embryos are placed in smart incubators to grow and divide cells naturally. After five days of follow-up and monitoring growth and division, a biopsy is taken to check the number of chromosomes of each embryos.
This examination helps in discovering embryos that are not genetically sound. They may contain fewer or more chromosomes. Genetically healthy embryos are implanted and the unhealthy ones are disposed of.
PGT-A Is a genetic test that is performed before transferring back the embryos. It identifies any chromosomal anomalies by NSG technology which we provide in Bedaya hospitals’ Laboratory.
This technology allows doctors to analyze the 24 pairs of chromosomes and detect disorders before transferring them to guarantee higher success rates of IVF or ICSI
PGT-A does not test for the following:
Pre-implantation genetic testing to detect chromosomal anomalies makes it possible for doctors to choose the best embryos for uterine transfer thus avoiding miscarriages or unhealthy pregnancies. Statistics show that women aged 38 to 40 who underwent an IVF process had a chance of chromosomal abnormalities in fetuses reaching up to 64%. To avoid implanting an embryo that has morphological or numerical abnormalities in its chromosomes this examination is done before embryo transfer to the uterus.
Before undergoing any procedure, you have the right to inquire your doctor about the risks and benefits of the procedure. this will help you take better decisions according to your situation.
43 years old Khaled and 37 years old Rohaifaa were married for 12 years, but they had delayed pregnancy health issues that prevented them from expanding their family. Rohaifaa’s period is quite regular but turned out to be diagnosed with polycystic ovaries and uterine adhesions. The Libyan couple tried ICSI back in 2010 and retried again in 2013, and this time led to a successful pregnancy. 10 eggs were taken from Rohaifaa ovum, 4 were implanted back into her uterus and 6 were frozen in case we had to redo the process again, or to be used for any future porpuses.
