An internal examination allows a doctor to look more closely inside the body at organs such as the prostate gland, ovaries or womb.
A ‘transvaginal’ ultrasound means ‘through the vagina’.
During the procedure, you’ll be asked to either lie on your back, or on your side with your knees drawn up towards your chest.
A small ultrasound probe with a sterile cover, not much wider than a finger, is then gently passed into the vagina or rectum, and images are transmitted to a monitor.
Internal examinations may cause some discomfort, but don’t usually cause any pain and shouldn’t take very long.
