What's hiding my ovaries on a pelvic ultrasound? can be seen on transvaginal ultrasound instead.

Normal variation: The position of the ovaries varies quite a bit from women to women within the pelvis. Secondly, gas within adjacent bowel loops will distort ultrasound images and 'hide' anything behind that loop. Thus looking from a different angle ie transvaginally, we can find the ovaries that we can see on the transabdominal portion of a scan.
