Endometrial Biopsy

Endometrial biopsies are used to evaluate the lining of the uterus (the endometrium). They can help determine the cause of abnormal vaginal bleeding, as well as assist in an infertility evaluation. We hope the information below answers your questions about the test.

What should I expect?
The biopsy is done in our office, and we offer Motrin or Tylenol before the biopsy. That will help decrease the cramping which may occur during the test. A speculum is placed in the vagina, as it would be for a Pap smear. A brown disinfectant will be applied to the vagina. You may hear us call this "Betadine".

You will then feel a pinch as the cervix or mouth of the womb is brought into adequate visualization. If the cervix is tightly closed, a local anesthetic called Lidocaine will be injected on both sides of the cervix; this may sting or burn briefly. After the Lidocaine has taken effect, an instrument will be passed through the mouth of the womb. You will feel a moderately uncomfortable cramp and then a dragging sensation. It is over quickly.

Are there any side effects?
You will probably have some spotting for a day that will require a pad. Some patients feel a little weak after the biopsy but this passes in 10-15 minutes.

When will I get the results?
We will get the results in about a week to ten days after the biopsy. We will make a follow-up appointment at that time to discuss the results.

We hope this answers some of your questions about the endometrial biopsy. Please feel free to call us if you have any further questions.
