Uterine anomalies
Uterine anomalies may be problems a woman is born with or that develop over time. For example, there can be congenital problems where the uterus doesn't form properly, so the uterine cavity can't carry a pregnancy to term. This usually leads to miscarriages rather than to an inability to get pregnant in the first place. In some women, the opening to the fallopian tube may not form correctly, or the cervix may not form correctly. These are relatively rare abnormalities.
Some uterine anomalies develop as you get older. This could include scar tissue, polyps, fibroids, or other growths that affect the endometrium or the cavity of the uterus, or interfere with implantation.
Fibroids are noncancerous tumors that grow in the uterus. They are extremely common; some 30 to 50 percent of women of reproductive age have fibroids, and fibroids are rarely the culprit in infertility. Women having infertility treatment may not need to have fibroids removed.
