Transvaginal ultrasound is a method of imaging the genital tract in females. A probe is inserted directly into the vagina. The probe is moved within the vaginal cavity to scan the pelvic structures, while ultrasound pictures are viewed on a monitor. The test can be performed to evaluate women with fertility problems, abnormal bleeding, unexplained pain, congenital malformations of the uterus and ovaries, and possible tumors and infection.
