Hysterography (HSG)

After taking blood tests to check your fertility and performing a pelvic ultrasound scan, your doctor might decide to perform a hysterography, or hysterogram, which is a fertility test consisting of an X-ray scan of the uterus (womb). It is used in cases of female infertility.

During the hysterography procedure, a radio-opaque liquid is injected into your uterus – this liquid is visible when the X-ray is performed and will allow your doctor to assess the shape and structure of your uterus and check that the Fallopian tubes are not blocked nor twisted.

The delicate mucosa (membrane) of the Fallopian tube is quite easily damaged by infections or adhesions. If an accumulation of liquid is observed this might indicate that the end of the tubule is blocked and that the egg will not be able to be fertilised by the sperm, preventing you from getting pregnant.

A hysterography procedure may be performed even if you display a normal ovulation pattern (as seen through your body basal temperature chart) and if your partner has a normal sperm count.
