Summary
Preimplantation genetic diagnosis (PGD) prevents genetic disorders across generations. This method uses screened, healthy embryos for pregnancy, avoiding traumatic pregnancy terminations.
Area of Science:
- Reproductive Medicine
- Genetics
- Embryology
Background:
- Genetic disorders pose risks to offspring.
- Pregnancy termination can be emotionally and physically traumatic.
- Preimplantation genetic diagnosis (PGD) offers an alternative to prevent transmission of genetic disorders.
Purpose of the Study:
- To introduce preimplantation genetic diagnosis (PGD) as a method for preventing the intergenerational transmission of genetic disorders.
- To highlight the benefits of PGD in avoiding pregnancy terminations.
Main Methods:
- PGD typically involves ovarian hyperstimulation and in vitro fertilization (IVF).
- Genetic testing is performed on embryos.
- Only genetically normal embryos are selected for uterine transfer.
Main Results:
- Successful establishment of unaffected pregnancies.
- Birth of healthy infants.
- Avoidance of pregnancy termination for affected pregnancies.
Conclusions:
- PGD is an effective approach for preventing genetic disorders.
- PGD reduces the need for termination of affected pregnancies.
- PGD contributes to the birth of healthy infants.
