Preimplantation Genetic Testing (PGT)
At Fertilite, we offer comprehensive Preimplantation Genetic Testing (PGT) to ensure the health of your embryos before implantation. This cutting-edge technology increases the chances of a successful pregnancy by screening for genetic abnormalities that could affect the development of the embryo.
PGT-A: Preimplantation Genetic Testing for Aneuploidies
PGT-A is designed to detect chromosomal abnormalities, specifically extra or missing chromosomes, which are known as aneuploidies. By identifying these abnormalities, we can prevent certain genetic conditions, such as Down syndrome, Turner syndrome, and Klinefelter syndrome, among others.
Indications for PGT-A:
- Women aged 35 or older
- Women who have experienced two or more spontaneous miscarriages
- Women with two or more unsuccessful IVF cycles
- Couples with a history of chromosomal abnormalities in previous pregnancies
- Severe abnormalities in male semen that may indicate chromosomal issues in the sperm
- Couples carrying numerical abnormalities in the sex chromosomes (X or Y)
- PGT-M: Preimplantation Genetic Testing for Monogenic Disorders
- PGT-M is used to screen for specific gene mutations that may cause inherited monogenic diseases. This test helps families avoid passing on conditions like cystic fibrosis, Huntington’s disease, and sickle cell anemia to their children.
PGT-M: Preimplantation Genetic Testing for Monogenic Disorders
Indications for PGT-M::
- One or both partners have been diagnosed with a genetic disorder
- Couples who are carriers of the same genetic mutation
- Family history of genetic diseases
Note: In autosomal recessive diseases, a person must inherit two copies of the mutated gene to be affected, while in autosomal dominant diseases, inheriting one copy is enough to cause the condition.
PGT-SR: Preimplantation Genetic Testing for Structural Rearrangements
Indications for PGT-SR:
- One partner is a carrier of a structural chromosomal alteration
Types of Chromosomal Alterations Detected:
- Translocations: Exchange of genetic material between chromosomes
- Deletions: Missing portions of chromosomes
- Duplications: Extra copies of chromosome segments
- Insertions: A fragment from one chromosome is inserted into another
- Ring Chromosomes: Chromosomes form a ring due to abnormal joining
- Inversions: Reversal of a chromosome segment
