Certain genetic risks present more often in pregnancy as women age. For example, the rate of having a baby with Down syndrome accelerates with maternal age.
While the rate of an embryo having Down syndrome at the 10-week mark of pregnancy is 1 in 1,064 at age 25, this rises to 1 in 686 at age 30 and 1 in 240 by the age of 35 years. At the age of 40, the Down syndrome rate increases still to 1 in 53, and down to 1 in 19 embryos at age 45.
