A sonohystereogram is a standard ultrasound test for all patients referred for infertility or recurrent miscarriage. The test can be ordered for any of the following reasons:.

• History of infertility
• To evaluate the fallopian tubes for patency (ie to see if they are open)
• Previous miscarriages
• Unexplained vaginal bleeding
• To identify uterine anomalies such as fibroids or polyps that may be interfering with your ability to get pregnant

A SHG can identify lesions within or impinging on the uterine cavity such as fibroids, polyps, and adhesions. It can also identify irregular thickening of the lining. The 3D uterine assessment performed during a SHG helps determine if there is a uterine shape anomaly such as a bicornuate, unicornuate, or septate uterus or uterus didelphys.

A sonohystereogram is performed between days 5 and 11 of the menstrual cycle when the lining of your uterus is thin. When the lining is thin, the doctor can more easily visualize any structural defects within the uterine cavity. The timing also reduces the likelihood that the patient is pregnant at the time of the test.

Pelvic cramping during the procedure is normal. After the procedure, you may experience some of the following:

• Continued cramping
• Light spotting
• Watery vaginal discharge
• Fever with or without pelvic pain. This is not normal and may be a sign of infection. Please contact your fertility doctor if this occurs. It is a rare occurrence.

Some patients tolerate the vaginal exam without discomfort, but some may experience pain, discomfort, cramping, caused by the speculum, catheter, and or saline solution. We treat every case with the utmost care, if you are nervous and expect discomfort, don’t be afraid to let the physician or sonographer know how you are feeling.
