It is generally agreed the while uterine fibroids are very common; they are usually not associated with infertility. Size and location are the two main characteristics, which determine if fibroids may be implicated in infertility or increased risk of miscarriage. These benign tumors have long been classified according to their location. Fibroids located within the uterine cavity are referred as submucous fibroids. If located within the uterine wall fibroids are classified as intramural, and when these tumors are positioned on the outer surface of the uterus, they are termed subserous.
