Hysterosalpingogram (HSG):This imaging test evaluates the uterine cavity and Fallopian tubes. During the procedure, a contrast dye is introduced into the uterus through a tube inserted via the vagina. As the dye progresses through the uterine cavity and into the Fallopian tubes, a series of images are captured. If the Fallopian tubes are unobstructed, the dye will pass through them and into the abdominal cavity, where the body absorbs it. The entire process lasts about 15-30 minutes and is typically conducted by a radiologist or a gynecologist in the hospital's radiology department.While anesthesia is not necessary, patients often receive mild sedatives and pain relief due to the cramping and discomfort that can occur, similar to menstrual pain. This test is primarily used to diagnose infertility issues. It can detect uterine abnormalities like polyps, fibroids, tumors, or foreign bodies, and identify any blockages in the Fallopian tubes that could impede pregnancy. A blocked tube can prevent an egg from traveling to the uterus or obstruct sperm passage.Additionally, a hysterosalpingogram can assess the success of surgery intended to reverse tubal ligation.
