Patient's question:
My good buddy has been married to his wife for nearly four years now. Before that, he didn't want children, but later wanted kids and kept trying but never succeeded. Just recently, he found out he was pregnant. They were all very happy about it, but when he went to the hospital for a check-up, the doctor confirmed that the fetus had a malformation. Why does fetal malformation occur? What are the factors that can lead to fetal malformation?Doctor's answer:
There are environmental factors that can cause fetal malformations, including drugs, chemicals, toxins, and other substances that can be encountered in the environment. Pregnant women's viral infections, abnormalities in the number or structure of chromosomes, and sex chromosome abnormalities can all lead to fetal malformations. Polygenic intergenerational inheritance combined with environmental factors often causes fetal malformations such as congenital heart disease, neural tube defects, cleft lip, cleft palate, and pyloric stenosis, which frequently occur again in female fetuses.
