Patient's question:
My brother and his sister-in-law have been divorced for 4 years. Now they want to have a child. Before trying to conceive, they underwent thorough medical examinations. The doctor confirmed a chromosomal abnormality. What does chromosomal abnormality mean?Doctor's answer:
Normal men or women have 23 pairs of chromosomes, totaling 46, which are primarily composed of DNA and proteins and serve as carriers of genetic information. According to your explanation, a thorough chromosomal examination before pregnancy suggests chromosomal abnormalities, but it is unclear which specific chromosome is affected and what the issue is. Further examination is recommended if necessary to clarify the situation. Some chromosomal abnormalities can lead to infertility, stillbirths, miscarriages, or fetal deformities. Therefore, it is essential to determine the exact cause.
