SIS (Saline Infusion Sonogram)

What is an SIS?

A Saline Infusion Sonohysterogram (SIS) (SHG) is an ultrasound study of the uterus and uterine lining (endometrium) that identifies abnormalities that may interfere with embryo implantation and fertility. This test is usually covered by medical insurance.

Why would I need an SIS?

An SIS is a must for a transfer cycle to optimize transfer success.

When can I get an SIS?

An SIS is performed in the clinic between 10:00am and 12:00pm. This can be done between days 5-9 of a transfer cycle, so there is no need to wait or waste time.

Do I need to prepare for my SIS?

No preparation is needed for the procedure, and it is not done under any form of sedation.  The entire procedure should take no more than 10-15 minutes and should be no more painful than a pap smear. 

What should I expect after the procedure?

You should feel well enough afterward to drive yourself home or back to work and may resume normal activities right away. 

Expect to have minimal vaginal spotting and some mild cramping. 

A small amount of sterile water may leak out as well. 

If you develop any fever, unusual pain or heavy vaginal bleeding, call the office immediately for prompt evaluation. 

If an abnormality is discovered with this test, corrective surgery may be recommended.
