Two of the more common uterine factors that can contribute to fertility problems are endometrial polyps and uterine fibroids.
Endometrial polyps are focal overgrowths of the cells that line the uterine cavity. They are rarely a cause for serious medical concern, but can decrease pregnancy rates by impairing implantation of a pregnancy. Uterine fibroids are a result of abnormal proliferation of smooth muscle cells in the muscular wall of the uterus. Fibroids that impact the uterine cavity can also contribute to fertility problems by affecting the implantation of a pregnancy.
