PREIMPLANTATION DIAGNOSES Meaning and
Definition
-
Preimplantation diagnosis (PGD) is a medical technique used in assisted reproductive technology to identify genetic abnormalities or disorders in embryos before they are implanted into the uterus. It involves the testing of embryos during the early stages of development, typically within the first few days after fertilization.
PGD is primarily used in cases where there is a high risk of passing on genetic disorders to offspring, such as certain chromosomal abnormalities, single gene mutations, or inherited disorders. The technique allows for the selection of embryos that are free from the identified genetic condition, thereby increasing the chance of a successful pregnancy and reducing the risk of passing on the disorder.
The process of PGD involves the removal of one or a few cells from the embryos, which are then analyzed for genetic abnormalities using various laboratory techniques, such as polymerase chain reaction (PCR), fluorescent in situ hybridization (FISH), or next-generation sequencing (NGS). The embryos that are found to be free from the identified genetic condition are then chosen for implantation, while those with the genetic abnormality are typically not used.
Preimplantation diagnosis has provided new opportunities for couples who may carry genetic disorders to have healthy children. It offers a way to screen embryos prior to implantation, promoting the selection of healthy embryos and reducing the likelihood of passing on genetic diseases. While controversy surrounds the ethical implications of PGD, it remains an important tool in reproductive medicine, providing hope for individuals and couples with a high risk of passing on genetic disorders.

Etymology of PREIMPLANTATION DIAGNOSES
The word "Preimplantation Diagnoses" is a combination of several terms:
1. Preimplantation - This word is derived from the Latin prefix "pre-", meaning before, and the word "implantation". "Implantation" refers to the process by which a fertilized egg attaches itself to the uterus lining. Therefore, "preimplantation" refers to anything that occurs before this implantation takes place.
2. Diagnosis - This word comes from the Greek terms "dia-", meaning through, and "-gnosis", meaning knowledge or understanding. "Diagnosis" refers to the identification or determination of a disease, condition, or problem.
