Hysterosalpingography
A hysterosalpingography (HSG) is a specialised X-ray test used to look at the inside of the uterus (womb) and fallopian tubes. It helps doctors assess the shape of the womb and whether the fallopian tubes are open or blocked.
Hysterosalpingography (HSG) is most often recommended as part of investigations into infertility, but it can also be used to check for scarring, structural changes, or other abnormalities of the uterus.
Your gynaecologist may recommend an HSG to:
Investigate possible causes of difficulty conceiving
Check for blocked fallopian tubes (which can prevent sperm and egg meeting)
Look for problems inside the womb such as fibroids, adhesions (scar tissue), or polyps
Confirm whether previous surgery on the womb or tubes has been successful
What's involved in a hysterosalpingography?
HSG provides valuable information about the womb and fallopian tubes, which can guide decisions about fertility treatment or other gynaecological care.
The whole process usually takes 30–60 minutes, depending on whether additional procedures are included.
Many people find reassurance in knowing more about their reproductive health after the test.
Your gynaecology team will explain the procedure beforehand, answer your questions, and ensure you are supported throughout. If further care is needed, your gynaecologist will work with you to plan the next steps.
Step 1
The procedure is usually performed under sedation or a light general anaesthetic to ensure you are comfortable.
Once you are asleep or sedated, the gynaecologist gently places a speculum into the vagina and passes a fine catheter through the cervix into the womb.
Step 2
A contrast dye is slowly introduced into the uterus and fallopian tubes. X-ray imaging is used to watch the dye flow, showing whether the tubes are open.
Step 3
In theatre, the gynaecologist may also carry out a hysteroscopy (looking inside the womb with a camera) or a laparoscopy (keyhole surgery to view the pelvis)
Step 4
If any abnormalities are seen, some treatments (such as removing small adhesions or polyps) may be performed during the same procedure.
