Preimplantation genetic testing, also known as PGT or pre-implantation genetic screening, is a diagnostic technique performed on embryos created through in vitro fertilization. This procedure evaluates the genetic makeup of embryos before they are implanted into the uterus to ensure optimal chances of successful pregnancy and healthy offspring.
PGT serves multiple purposes for enhancing reproductive outcomes:
Reducing Risk: By identifying embryos without chromosomal abnormalities, PGT significantly decreases the risk of miscarriage and ensures that only genetically healthy embryos are transferred.
Couples with Genetic Risks: For individuals or couples at risk for inherited genetic disorders in their offspring, this test allows selection agnst potential genetic conditions before pregnancy.
Preventing Miscarriages: In cases where recurrent miscarriages are attributed to chromosomal abnormalities in the embryo, PGT provides a pathway towards successful implantation and carrying pregnancies to term.
PGT is particularly beneficial for:
Individuals over 37 years of age due to elevated risks associated with advanced maternal or paternal age.
Couples who have experienced recurrent miscarriages without clear medical diagnosis.
People with hereditary conditions that could potentially affect their offspring, providing a method to avoid passing these disorders.
begins with undergoing in vitro fertilization IVF to generate embryos. Once embryos reach the blastocyst stagea critical juncture of developmentPGT can be conducted by performing a biopsy on several cells from the embryo's outer layer. These cells are then sent for genetic testing to screen for abnormalities.
