The overall percentage of pregnancies that end in miscarriage
lies between 10-15%. Miscarriage accounts for about 50,000 in-patient
admissions to hospitals in the UK annually. Recurrent miscarriage affects
1% of all women. This incidence is greater than that expected by chance
alone (0.34%). The risk of miscarriage increases with advancing maternal
age from about 9% at age 20 years to 80% at age 48 years. It is worth
noting that this increase is observed irrespective of a woman's reproductive
history.
