Tests & investigations
Contrast is passed through the cervix while X-ray images are taken, showing the shape of the uterine cavity and whether dye spills from the ends of the tubes. It is usually done in the first half of the cycle, after pregnancy has been excluded. Cramping is common; many clinics advise taking a simple analgesic beforehand. Contact the clinic urgently for fever, heavy bleeding or severe pain afterwards.
Also known as: HSG, tubal dye test, hysterosalpingogram
