The chances of having a natural miscarriage in young women range between 12 and 15%, and they increase to 25% in women older than 40 years old. In cases of IUI, where the woman is typically younger than 37 years old, the miscarriage rate is about 20%. Thus, the answer is yes, the risk of miscarrying is slightly higher.
Is the miscarriage rate associated with IUI higher than in natural pregnancies?
