Why is hysterosalpingography performed?
A – An HSG may be recommended in cases of infertility in order to diagnose a blockage of one or both tubes that may prevent union of the sperm and egg. In addition, because this procedure provides an image of the outline of the uterine cavity, it may help in detecting abnormalities of the uterus that could cause infertility, repeated miscarriages, or abnormal vaginal bleeding. The HSG procedure is sometimes performed before tubal ligation reversal surgery in order to show the lengths of the remaining tubes.
