Uterine Polyps Can Cause Infertility or Miscarriage

A "normal" uterine cavity and endometrial lining is necessary in order to conceive and maintain a pregnancy. Uterine polyps sometimes cause problems with infertility - or with miscarriages.
What is a uterine polyp?
A polyp is an overgrowth of tissue in the lining (endometrium) of the uterus. The concept is similar to that of a skin tag - basically normal tissue, but growing in an abnormal formation. Many polyps are very small (a few millimeters in diameter) and do not represent a compromise to reproductive capabilities. However, large polyps - or multiple polyps - can interfere with reproduction by causing infertility, or by increasing the risk of miscarriage.
Ultrasound picture with polyps:
The picture on the left is an ultrasound of a uterus with polyps in the endometrial lining. They can not be seen well here because they are hidden in the normal endometrial tissue.
The photo on the right shows a the same uterus with sterile salt water injected in the uterine cavity. This test is called a sonohysterogram, or hydrosonography. The polyps are surrounded by water (black) and are easily seen - one is between the white "X" cursors.
Normal uterus on ultrasound:
For comparison, ultrasound images of a uterus with a normal endometrial lining. Image on right shows the uterus outlined in blue and the "triple stripe" uterine lining (landing pad for the embryos) outlined in yellow. |
This picture is a hysteroscopic view of the inside of the same uterus with polyps that is shown above. Hysteroscopy is done by inserting a narrow scope through the cervical opening allowing visualization of the uterine cavity. Surgical instruments can be put through the scope to cut and remove abnormal tissue. A polyp is shown here. All of the polyps were resected during this procedure, leaving a perfectly normal cavity. |
