Preimplantation genetic testing for structural rearrangements (PGT-SR) can be beneficial for patients diagnosed with an abnormal karyotype or a rearrangement of their genetic material, who may face challenges in conceiving a healthy pregnancy. PGT-SR involves analyzing embryos from patients with known chromosomal structural rearrangements, such as inversions or translocations. These patients are at a higher risk of producing embryos with incorrect amounts of chromosomal material, which can lead to difficulties in natural conception and potentially result in implantation failure or recurrent miscarriage. By screening embryos for these abnormalities before implantation, PGT-SR increases the chances of a successful and healthy pregnancy. This advanced technology provides hope for patients with abnormal karyotypes, enabling them to make informed decisions about their reproductive options and enhancing their chances of achieving a healthy pregnancy.
