A sonohystogram (or hysterosonogram) is a detailed look at the inside of your uterus. The procedure isn't painful and generally only takes about 10 minutes.

Your doctor may recommend a hysterosonogram if you have problems trying to conceive, abnormal bleeding, or miscarriages. The test can diagnose uterine fibroids, polyps, endometriosis, or other conditions.

Preparing for the test

  • While you probably won't experience any pain, it is a good idea to take ibuprofen an hour before the procedure to minimize discomfort from possible cramping.
  • You will probably be asked to drink about four glasses of water an hour before the appointment so that you have a full bladder during the test. This gives the technician a clearer view of your reproductive organs.

The procedure

  • You will lie on an examination table with your feet in stirrups, as you would for a regular pelvic exam. The technician will insert a speculum and then a special ultrasound probe into your vagina.
  • A catheter will insert sterile saline solution (salt water) into your uterus, which expands it and gives the technician a good view of the inside of your uterus.
  • You may experience some cramping when your uterus fills with saline solution, but it usually goes away when the solution comes out after the test.


  • You may have some light bleeding or cramping for a few days after the procedure. Infection is rare.
