Turner syndrome is a congenital ovarian hypoplasia, which is a relatively common abnormality of sexual development caused by chromosomal deletions, and the gene that causes the disease is carried by the mother. In clinical practice, about 18-20% of fetuses with Turner’s syndrome are spontaneously aborted, and if the fetus has Turner’s syndrome, the miscarriage rate can be as high as 99%. For example, after pregnancy, you can do Down’s syndrome screening, 4D ultrasound, etc. Only through maternity checkups can abnormalities be detected and dealt with in a timely manner to reduce the birth of deformed or abnormal children.
