Firstly, the primary difference between babies born through IVF (In Vitro Fertilization) and those born through natural delivery lies in the fertilization process and the location of embryo implantation. Babies born through natural delivery are conceived naturally within the mother’s body, where the fertilized egg implants in the uterus and develops into a fetus. In contrast, babies born through IVF in the United States are conceived outside the body, where sperm and egg are combined in a laboratory dish to form an early-stage embryo, which is then transferred into the mother’s uterus for further development.

According to tracking reports investigating 5000 IVF babies across different age groups, it has been shown that IVF babies in the United States are as healthy as those born through natural delivery. There are no differences in terms of physical health, psychological resilience, intelligence levels, or social development. With the continuous advancement of IVF technology in the United States over three generations, recent research reports indicate that the overall quality of IVF babies in the United States tends to surpass that of naturally conceived babies. Approximately 45% of IVF babies achieve excellent levels of intelligence, and there is a higher chance of multiple births compared to natural delivery. Moreover, with the application of third-generation IVF techniques such as PGD (Preimplantation Genetic Diagnosis) and PGS (Preimplantation Genetic Screening), the incidence of congenital defects among IVF babies in the United States has significantly decreased compared to babies born through natural pregnancy and delivery.
