Infertility Diagnosis

What Is Hysterosalpingography?


A hysterosalpingography (HSG) is a specific fluoroscopic X-ray procedure that assesses patency of fallopian tubes and shape of uterine cavity.

How can HSG help with diagnosis of infertility?
HSG is a significant diagnostic component of basic assessment of infertility because one of the major causes of infertility is obstructed fallopian tubes. Other indications for HSG may include repetitive miscarriages, abnormal vaginal bleeding, or suspected uterine abnormalities.


How Is HSG Procedure Performed?
HSG is an outpatient procedure and can be completed less than half an hour. HSG is performed after menstrual bleeding stops, during the follicular phase of menstrual cycle (before ovulation). A thin catheter is inserted into the cervix and uterus to inject a radioopaque contrast substance (a dye used to visualize the outline of fallopian tubes under X-ray). As the dye or substance travels through the uterine cavity, HSG provides a series of fluoroscopic images to show the condition of uterine cavity and fallopian tubes.
