A child with xxy chromosome is not recommended. A child with xxy chromosomes is part of Crohn’s syndrome, which is a congenital disorder with chromosomal abnormalities. It manifests as congenital testicular hypoplasia and underdevelopment of the male secondary sex characteristics, i.e., male feminization. Because of their incomplete development of these physical organs, their probability of being fertile is small. Intellectual development is normal or slightly low. The patient has no abnormalities in childhood, but often develops abnormalities only during puberty or adulthood. Therefore chromosome xxy has a great impact on the child’s life and may cause great suffering, it should be considered carefully and is not medically recommended. Early screening tests are needed between 11 and 13 weeks of pregnancy, which is NT screening, to confirm whether the fetus is at risk of chromosomal abnormalities. Every pregnant woman should pay attention to do a good job of prenatal checkups during pregnancy, and actively listen to the advice of professional doctors to do a good job of comprehensive care and health care, which can effectively ensure the safety of the birth.
