Fertility Test: Sonohysterography
A sonohysterogram (SH) is a procedure in which saline fluid is placed into the uterine cavity through the cervix while an ultrasound machine is used to look at the cavity. The fluid in the cavity allows a better look at it because the fluid enhances the images. Here are some helpful tips:
- The reasons SH would be recommended include: changes in menstrual bleeding patterns, or the lining looks different than it looked previously (suggesting a uterine polyp or fibroid) when you are having a standard transvaginal ultrasound. An SH may also be recommended because the cavity had a filling defect, an area where the contrast did not fill in within the uterine cavity on a hysterosalpingogram.
- Anything abnormal in the cavity — for example, polyps, fibroids or scarring — can interfere with establishing a pregnancy.
- The procedure is scheduled after your menses but before ovulation, usually cycle days 6 through 12.
- The risk of getting an infection from the test is very small, but prophylactic antibiotics may be recommended to you.
- Most women (greater than 90 percent) find this procedure to be very tolerable. A small percentage of women get some cramping. If you have taken ibuprofen and it has helped you with menstrual cramps, you may take 800 mg approximately 1 to 1 1/2 hours prior to your scheduled procedure time to minimize discomfort.
