Pelvic ultrasonography may identify congenital abnormalities of the uterus, cervix, and vagina, or absence of these organs. However, a report of absence of the uterus on ultrasonography does not always mean that the patient does not have a uterus. In primary amenorrhea in association with estrogen deficient states, the uterine fund us may be underdeveloped and may not be readily visible at the time of ultrasonography to less experienced examiners. With proper estrogen replacement, it may reach the normal size.

Pelvic ultrasonography may be helpful in determining ovarian morphology as well. However, in most cases of amenorrhea without androgen access, the information obtained with ovarian ultrasonography does not change clinical management.
