1 An increase in maternal age affects the chances of miscarriage. 2  Women under the age of 35 yrs old have about a 15% chance of miscarriage. 3  Women who are 35-45 yrs old have a 20-35% chance of miscarriage. 4  Women over the age of 45 can have up to a 50% chance of miscarriage.
But the latter group, it turns out, was less likely to miscarry again and more likely to have a live birth. Women who conceived within six months of their miscarriage were 34% less likely to miscarry again, compared with those who became pregnant six months to a year after the initial miscarriage. While the study did not address the causes of miscarriage, Bhattacharya speculates that age may be a dominant factor.
