Understanding Infertility

A sonohysterogram (SHG) is an ultrasound of the uterus that creates pictures using sound waves. The SHG is painless and easy to perform.

​

It is performed by inserting a thin tube (catheter) into the cervix. Saline solution is that fed through the tube and expands the uterus slightly. A transvaginal ultrasound wand is then placed into the vagina in order to capture pictures of the reproductive system.[1]

This procedure can look more closely for a reason for infertility, such as polyps, endometriosis, or irregularities in the lining or uterine shape.

​

Cramping or light bleeding may occur, but as it is minimally invasive, you can leave as soon as the SHG is finished.[2]
