Can Fibroids or Other Uterine Problems Cause Miscarriage?
Anatomical abnormalities can predispose a woman to pregnancy loss. In particular, congenital uterine abnormalities such as a uterine septum (a fibrous band separating the uterine cavity into two smaller cavities) or a unicornuate uterus (a small malformed uterus that is usually connected to a single fallopian tube) can lead to poor reproductive outcomes. Uterine malformations as a result of prenatal exposure to diethylstilbestrol (DES) can also increase a woman’s risk of a poor pregnancy outcome.
The presence of uterine fibroids within or abutting the endometrial cavity has been proposed as a source of pregnancy loss the same is true of uterine polyps. Extensive intrauterine adhesions from a previous dilatation and curettage (D&C) procedure may also lead to reduced reproductive success. All of these abnormalities may be amenable to surgical correction, but the decision to pursue surgery requires a careful discussion with your physician.
