PELVIC ULTRASOUND (TRANSVAGINAL ULTRASOUND)
Transvaginal ultrasound (TVS) is routinely used in the initial evaluation of the infertile patient and provides information about tubo-ovarian pathology (i.e. ovarian cyst, endometrioma, large hydrosalpinx) and uterine pathology (i.e. fibroids, endometrial polyps, and uterine anomalies). Advantages of TVS are that it is a simple tool with almost no infection risk, generally well tolerated, radiation-free method which provides information on the size and position of the uterus, and tubo-ovarian pathology. The disadvantages of TVS are its limited sensitivity and specificity in diagnosing abnormalities of the endometrial cavity and tubal pathology such as tubal blockage (i.e. hydrosalpinx).
