The uterus and miscarriage

Several abnormalities of the uterus are commonly linked to repeated pregnancy loss. Most of them can be treated with surgery.

They include:

• Congenital abnormalities. These are defects present from birth. For instance, a woman may have a uterus that is divided into two sections by a wall of tissue (septate uterus).
• Uterine fibroids (leiomyomata). Uterine fibroids are benign growths (not cancer) made up of uterine muscle tissue.
• Incompetent cervix. An incompetent cervix is one that begins to widen and open too early, in the middle of pregnancy, without any sign of pain or labor. Incompetent cervix is not a cause for recurrent first trimester losses.
