Genetic testing of embryos allows prospective parents to screen for potential genetic diseases or disorders before implantation. There are several reasons why couples may consider this procedure.
- IMPROVED IMPLANTATION RATES
Testing embryos helps identify those most likely to result in a successful pregnancy after transfer to the uterus. By selecting embryos with the highest viability, the chances of implantation and live birth can be increased.
- REDUCED RISK OF GENETIC DISEASE
For couples concerned about passing on an inherited disease or disorder, genetic testing allows them to identify embryos unaffected by the condition in question. This helps ensure their child will not be born with or develop the disease. Examples include Huntington’s illness, sickle cell anemia, and cystic fibrosis.
- GENDER SELECTION
Some couples use genetic testing to choose the gender of their baby. By identifying male and female embryos, they can select those of the desired sex for transfer. However, this is a controversial issue and banned in some countries and states.
- PEACE OF MIND
Undergoing embryo testing and selecting a healthy, viable embryo can provide reassurance and reduce anxiety for prospective parents worried about their baby’s health and development. Knowing the embryo has a reduced risk of genetic abnormalities allows couples to feel more at ease during pregnancy and birth.
The primary reasons for genetic testing of embryos are to improve success rates of IVF, reduce the risks of genetic disease, select for gender, and provide peace of mind. For many, the benefits of a healthy baby and an uncomplicated pregnancy and childbirth far outweigh the costs and risks associated with this procedure.
