Patient's question:
I want a second child because I am worried about genetic problems as I get older. I want to have the second child through American test tubes. I want to know how American test tube doctors can basically ensure the health of the baby? How do test tube doctors in the US basically ensure the health of the baby when there are chromosomal abnormalities?Doctor's answer:
Women's risk of embryonic chromosomal abnormalities increases with age, leading to issues such as miscarriage, biochemical pregnancy, ectopic pregnancy, premature birth, and fetal malformations, often causing pregnancy to be a "tricky journey." To prevent such occurrences, American lab doctors perform genetic screening and diagnosis on blastocysts before implantation. By cultivating the fertilized egg to the fifth day to form a blastocyst composed of over 100 cells, and then flexibly applying PGS/PGD technology for genetic testing, it is possible to accurately identify how the 23 pairs of chromosomes in the blastocyst are abnormal, diagnose 274 genetic diseases, and ultimately select high-quality, healthy blastocysts for implantation into the uterine cavity.
