Editors note: Embryos (viable humans) sacrificed for future birth selection ?
What is preimplantation genetic diagnosis?
Preimplantation genetic diagnosis (PGD) is a screening test used to determine if genetic or chromosomal disorders are present in embryos produced through in vitro fertilization (IVF).
(So otherwise "fertile" couples screen for birth defects by sacrificing an embryo...a human)
Preimplantation genetiagnosis screens embryos before they are transferred to the uterus so couples can make informed decisions about their next steps in the IVF process. Embryos unaffected by the genetic or chromosomal disorder can be selected for transfer to the uterus.
For couples undergoing IVF, preimplantation genetic diagnosis may be recommended when:
One or both partners has a history of heritable genetic disorders
One or both partners is a carrier of a chromosomal abnormality
The mother is of advanced maternal age
The mother has a history of recurrent miscarriages
Thousands of clinical preimplantation genetic diagnosis cycles have been performed worldwide, resulting in the birth of hundreds of healthy babies.
