Details the incidence of miscarriage and how the risk of miscarriage increases with age.

The incidence of miscarriage

The risk of miscarriage is known to increase with age.

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.
