Patient's question:
During this time, I got pregnant with a baby. When I went to the hospital for prenatal testing, it showed that it was a trisomy chromosome. I went through the process, and I'm very worried that it might have some impact on my second pregnancy. Does trisomy affect the second pregnancy?Doctor's answer:
Most chromosomal abnormalities in fetuses are caused by poor quality sperm or eggs, chromosomal abnormalities in both partners, poor environmental conditions, or dietary factors, all of which can lead to gene mutations. It is recommended to undergo medical examinations for sperm quality and both partners' chromosomes before attempting pregnancy again to check if they are normal and to avoid the possibility of recurrent fetal abnormalities. Begin taking folic acid tablets three months before pregnancy to prevent cardiovascular malformations in the fetus. Avoid smoking and drinking alcohol, and develop good lifestyle habits.
