Here is a case of uterine hypoplasia (infantile uterus/female hypogonadism) that is considered a class I Müllerian duct anomaly.

In this case, the uterine volume is markedly small for the patient’s age. Surprisingly, the uterine length and uterine body to cervical ratio are within normal. Accordingly, it is better to use both methods to reach the right diagnosis.

Further hormonal essay and chromosomal analysis are recommended

For a detailed discussion of uterine measurements, see here.
