Final answer:
Prenatal genetic diagnosis (PGD) is the prenatal genetic testing method used alongside in vitro fertilization (IVF) to screen embryos for genetic conditions before implantation.
Step-by-step explanation:
The prenatal genetic testing method done in conjunction with in vitro fertilization (IVF) is known as prenatal genetic diagnosis (PGD). PGD is a sophisticated procedure that involves screening human embryos for genetic conditions during the IVF process. This process entails collecting eggs from a woman, fertilizing these outside her body, usually in a petri dish, and allowing the embryos to grow to a certain stage before one or more are selected and implanted into the uterus.
With PGD, embryos conceived through IVF can be tested for genetic abnormalities before they are transferred back into the woman's body, ensuring that only healthy embryos are implanted. This advanced procedure is significant for individuals and couples facing infertility issues or those who have a high risk of passing on genetic disorders.
