Tests & investigations
A transvaginal ultrasound uses a slim probe placed in the vagina, giving much clearer images of the ovaries, follicles and womb lining than a scan through the abdomen. It is the standard scan for antral follicle counts, follicle tracking and lining measurement. It should not be painful, though it can feel uncomfortable; you can ask to insert the probe yourself or to have a chaperone present.
Also known as: internal scan, TVS, vaginal scan
