It depends: Women with down syndrome can get pregnant, and often their pregnancies are complicated. If the down syndrome in the mother is caused by one extra chromosome 21, then the risk that she will conceive a child with trisomy 21 is about 50%.

Then the risks might be higher, even 100%. ...Read moreSee 1 more doctor answer
