PGD Meaning and
Definition
-
PGD, short for Preimplantation Genetic Diagnosis, is a specialized medical technique used during in-vitro fertilization (IVF) treatments to screen embryos for genetic abnormalities or specific genetic conditions before they are implanted into the uterus. It allows prospective parents to have a greater chance of having a healthy child and helps them make informed decisions about whether to proceed with an embryo transfer.
During PGD, cells from the early-stage embryos, usually consisting of five to six days old, are carefully extracted and analyzed to identify potential genetic abnormalities or specific genetic conditions. These conditions may include inherited disorders, such as cystic fibrosis or sickle cell anemia, as well as chromosomal abnormalities like Down syndrome or Turner syndrome. The analysis is typically carried out using various genetic testing methods, such as polymerase chain reaction (PCR), fluorescence in situ hybridization (FISH), or next-generation sequencing (NGS).
Based on the test results, the embryos can be categorized into those that are free from genetic abnormalities or conditions, those that are affected by a specific genetic disorder, and those that are likely carriers of a particular condition. This information empowers prospective parents to decide which embryos to select for implantation and increases the chances of having a healthy baby without the genetic condition in question.
PGD offers individuals or couples who carry genetic disorders or have a family history of such disorders the possibility of reducing the risk of passing these conditions onto their offspring. It plays a crucial role in reproductive medicine and provides important reproductive options for individuals and families who may be affected by genetic diseases or conditions.
