Another instrument may be needed to gently stretch the cervical opening if there is tightness. An instrument is gently passed through the cervix into the uterus to collect the tissue sample. The tissue sample and instruments are removed. The tissue is sent to a lab. There, it is examined under a microscope. If you had anesthesia for the procedure, you are taken to a recovery area. Nurses will make sure you are comfortable. After you wake up and have no problems from the anesthesia and procedure, you are allowed to go home. How to Prepare for the Test Before the test:Tell your provider about all the medicines you take. These include blood thinners such as warfarin, clopidogrel, and aspirin. You may be asked to have a test to make sure you are not pregnant. In the 2 days before the procedure, do not use creams or other medicines in the vagina. Do NOT douche. (You should never douche. Douching can cause infection of the vagina or uterus.) Ask your provider if you should take pain medicine, such as ibuprofen or acetaminophen, just before the procedure. How the Test will Feel The instruments may feel cold. You may feel some cramping when the cervix is grasped. You may have some mild cramping as the instruments enter the uterus and the sample is collected. The discomfort is mild, though for some women it can be severe.

External structures include the labium minora and majora, the vagina and the clitoris.Female reproductive anatomyillustrationEndometrial biopsy - illustration The mucosal lining of the cavity of the uterus is called the endometrium. It is this lining which undergoes changes over the course of the monthly menstrual cycle, sloughes off and becomes part of the menses. A biopsy of the endometrium is used to check for disease or problems of fertility. Endometrial biopsyillustrationUterus - illustration The uterus is a hollow muscular organ located in the female pelvis between the bladder and rectum. The ovaries produce the eggs that travel through the fallopian tubes. Once the egg has left the ovary it can be fertilized and implant itself in the lining of the uterus. The main function of the uterus is to nourish the developing fetus prior to birth. UterusillustrationEndometrial biopsy - illustration An endometrial biopsy is a procedure in which a tissue sample is obtained from the endometrium (the inside lining of the uterus) and is then observed under a microscope. The tissue is thoroughly examined for any cell abnormalities or cancer. The test also helps determine the cause of abnormal menstrual periods, and can be used to screen for endometrial cancer. The test is sometimes used as part of the diagnostic work-up of women who have been unable to become pregnant.
