Question
Is embryonic chromosomal abnormality a cause of miscarriage?
Answer
Embryonic chromosomal abnormalities are a common cause of miscarriage. A 32-year-old woman experienced a spontaneous miscarriage at 80 days of pregnancy, and examination of the miscarriage product revealed an extra chromosome in the 16th pair. This chromosomal abnormality can lead to embryonic malformation, and even if the embryo survives, it may still develop congenital defects. Everyone should have 23 pairs of chromosomes, but this embryo has an extra chromosome in the 16th pair, which is what we usually refer to as a chromosomal abnormality. There are many factors that can lead to chromosomal abnormalities, including genetic factors and any factors that could be harmful to human health. I hope my explanation is helpful to you.
