Hysterosalpingogram (HSG)

Share the information

Hysterosalpingogram (HSG) is an x-ray examination that is used to evaluate the uterine cavity and to check for patency of the fallopian tubes (whether the tubes are blocked).


  • Infertility (difficulty in conceiving).
  • Confirm tubal and uterine abnormalities.
  • Recurrent miscarriages.
  • Follow-up to some surgical procedures.


  • Undiagnosed vaginal bleeding.
  • Pelvic inflammatory disease (PID).
  • Pregnancy.
  • Recent curettage or active genital tract infection.


  • It is best to schedule the procedure following completion of menstrual flow and before the tenth day. Please discuss this with your doctor if you are unsure or if you suspect that you may be pregnant.
  • If you have abnormal vaginal discharge, please inform your doctor. The procedure should be deferred until the infection has been ruled out or has been adequately treated.
  • No fasting is required. However, it is not advisable to take a full meal just prior to the procedure.
  • You should inform the doctor if you have a history of asthma, allergy to seafood, medications, or contrast.
  • Oral pain-killer medications and antibiotics may be given one hour prior to the procedure. This will help to reduce the pain and risk of infections. Additional doses may be given for you to take home. Please follow the instructions carefully when taking these medications.
  • Call the hospital to schedule an appointment for this procedure once your menstrual flow starts. This is to enable the hospital to schedule it before your tenth day (counting from the first day of menstrual flow).
  • Please abstain from unprotected sexual intercourse before the procedure or use a safe method such as condoms.
  • It is advisable to get an accompanying person to drive you home after the procedure.


  • The procedure is quick; usually takes about 15 to 20 minutes from start to finish.
  • No specific anaesthesia is required. You will be conscious during the procedure.
  • A speculum is inserted into the vagina and the cervix is visualized. The cervix and vagina are clean with an antiseptic.
  • A disposable balloon catheter is inserted into the uterine cavity and a dye (contrast medium) is slowly inserted into the uterus. X-rays are taken before and during the injection of dye. There may be some cramping or discomfort felt as the dye is injected. You may be asked to change positions for different x-ray views.
  • The x-rays will show the outline of the uterus and fallopian tubes as the dye fill them and spill into the abdominal cavity.
  • At the end of the procedure, all instruments are removed.
  • The results will be available immediately.


  • Normal findings reveal a symmetrical uterine cavity, with the dye flowing through unblocked fallopian tubes, and there is no leak of dye from the uterus.
  • The x-rays may help reveal an abnormality in the shape/size of the uterine interior, scarring, tumors (fibroids), endometrial polyps, or a blockage in the fallopian tubes.
  • Conditions detected by the hysterosalpingogram may require further testing for confirmation; this may include a laparoscopy or hysteroscopy (use of a small lighted telescope to view internal organs).


  • Allergic reaction to the solution used in the test.
  • Uterine perforation.
  • Infection.


  • Mild cramping, a slow pulse, some nausea, or dizziness may occur during or following the procedure. These are temporary.
  • Expect some vaginal spotting after the procedure but no heavy vaginal bleeding. Also, the solution used to clean the vagina and cervix and some of the dye itself will leak out through the vagina after the procedure. Wear a sanitary napkin for one or two days.
  • Antibiotics may be prescribed to prevent infection prior to or after the procedure.
  • Following the procedure, mild painkillers medications can be continued if the pain is present.
  • There are no dietary or activity restrictions once any temporary symptoms disappear.
  • You may return to work the following day if you are well.


  • Increased pain in the lower abdomen or in the genital area.
  • Signs of infection: headache, muscle aches, dizziness, or general ill feeling and fever.
  • Persistent or heavy vaginal bleeding.
  • Persistent and abnormal vaginal discharge
