Does an transvaginal ultrasound show if i have blocked tubes?

Typically not.: Ultrasound would show if you have blocked tubes if the blocked tubes are dilated. If the tubes are not dilated, they typically would not be visible on ultrasound. A hysterosalpingogram then may be useful.

Not always: A transvaginal ultrasound will be able to identify hydrosalpinx, which is when the tubes fill up with fluid and get dilated or enlarged. This often happens when there is a blockage. Ultrasound could miss a blockage if the tube is not dilated or only mildly dilated. Hysterosalpingogram (injection of dye into the uterine cavity) can identify blockages even when ultrasound can not.
