During pregnancy, expectant parents are often filled with anticipation and joy. However, the uncertainty of prenatal test results casts a shadow over this joy. Especially when prenatal examinations reveal chromosomal abnormalities in the fetus, it undoubtedly deals a heavy blow to the family. Chromosomes, as the carriers of human genetic information, their abnormalities will directly lead to developmental abnormalities in the fetus, and these abnormalities cannot be reversed through postnatal treatment.

Chromosomal abnormalities cover two major aspects: numerical abnormalities and structural abnormalities. The normal chromosomal composition of humans is 23 pairs, and an increase or decrease in the number of chromosomes will cause obstacles in embryonic development. If the number of embryonic chromosomes is abnormal, most will stop developing in the early stages. Even if they survive, they may face the risk of severe developmental malformations or intellectual disabilities. Take Trisomy 21 (Down Syndrome) as an example. This disease is caused by an extra copy of chromosome 21 in the embryo. Infants with this condition often suffer from intellectual disability, special facial features, developmental disorders, and multiple malformations. Moreover, 60% of infants with Trisomy 21 suffer from early miscarriage.

Facing the severe challenges posed by chromosomal abnormalities, prevention has become the key. Measures such as genetic counseling, chromosomal testing, prenatal diagnosis, and selective abortion constitute an effective defense line to prevent the birth of infants with chromosomal abnormalities. Pregnant women should undergo regular prenatal examinations to detect problems in a timely manner. Methods such as amniocentesis can detect whether the fetus has congenital chromosomal defects, providing a scientific basis for family decision-making.

To more effectively prevent embryonic chromosomal abnormalities, the scientific community has continuously explored new technologies. Among them, the third-generation IVF-PGT technology (Preimplantation Genetic Screening) in the United States stands out for its efficiency and accuracy. This technology can screen out over 120 chromosomal genetic diseases, providing a solution for infertility or miscarriage issues caused by embryonic genetic abnormalities in older women. Through PGS technology, doctors can screen out healthy embryos before embryo transfer, thereby fundamentally improving the success rate of pregnancy, reducing the rate of spontaneous abortion, and enhancing the quality of pregnancy. The application of this technology effectively avoids the tragedy of terminating pregnancy during pregnancy due to the transfer of embryos carrying abnormal genes.

In summary, preventing embryonic chromosomal abnormalities requires a comprehensive approach, including genetic counseling, prenatal examinations, and selective abortion. At the same time, with the help of the third-generation IVF-PGT technology in the United States, we can more accurately screen out healthy embryos, bringing hope to families for giving birth to healthy babies. Currently, IVF USA provides services such as egg freezing and IVF-PGT in the United States, and its business has expanded to regions beyond the United States, including Japan, Thailand, Mexico, Taiwan, Hong Kong, and other areas. It closely cooperates with IVF doctors worldwide. In this process, IVF USA and Dr. Nathan Zhang have provided high-quality IVF services to many families with their professional medical teams and advanced technical equipment, helping them realize their dreams of giving birth to healthy babies.
