Age and risk of miscarriage


Age and risk of miscarriages


Advancing maternal age is associated with a reduction in both the number and quality of the remaining eggs.

A large study has reported the age-related risk of miscarriage in recognised pregnancies to be:


Age Risk of miscarriage
12-19 years 13%
20-24 years 11%
25-29 years 12%
30-34 years 15%
35-39 years 25%
40-44 years 51%
45 years and above 93%



More recently, advanced paternal age has also been identified as a risk factor for miscarriage.
