Chromosome image: Results: 46.XX.iv(9)(p12q12) Description: Peripheral blood was cultured and then stained.Doctor's answer:
Analysis of the condition: Hello, chromosomal abnormalities are the most common cause of miscarriage. The DNA on chromosomes carries a vast amount of information, controlling all the programs for proteins in every organ and tissue of the body. Generally, individuals with chromosomal abnormalities also have abnormal nuclei in their fertilized eggs.Recommendations: Since you can conceive normally, there is no need for in vitro fertilization (IVF), as the purpose of IVF is to achieve pregnancy. Moreover, artificial selection of sperm and egg cells does not have the advantage of natural selection. If there is a genetic abnormality, it may still lead to miscarriage, or the child may have some abnormalities in the future.
