The risk of having a baby with Down syndrome for a 30-year-old woman increases

The risk of aneuploidy is increased with multiple miscarriages not attributable to other causes such as endocrine abnormalities or cervical incompetence.A 45, X karyotype results from loss of chromosome material and does not involve increased risks for nondisjunction errors.Similarly, induced ovulation does not result in increased nondisjunction, and hyper model conceptions (triploidy) do not increase the risk for future pregnancies.
