The dye flushes out the fallopian tubes, clearing partial, minor blocks in some women. In this is the case, the HSG test result will show unblocked fallopian tubes. However, some contrast may seem to stop and then continue on the x-ray. This may be the dye breaking through very thin adhesions.
Another possibility is that the dye solution enhances the endometrium (the lining of the uterus) in some way, making it easier for an embryo to implant successfully. It may have an anti-inflammatory effect.
The dye solution somehow affects the area surrounding the ovaries, enhancing ovulation.
Treatment for a blocked tube depends on the location of the obstruction. If only one tube is blocked, fertility medications could be used to increase the chances of ovulation on the side of the patent tube.
Alternatively, laparoscopic surgery may be indicated to remove the blockages. Women with tubal obstruction who wish to become pregnant and do not want to undergo surgery may consider in vitro fertilization (IVF).
