ABSTRACT

Correlation exists between Tanner staging and the uterine and ovarian volumes.1 Initially, there is a 50:50 size ratio between the uterine fundus and the cervix. This association changes during pubertal development, the cervix ultimately becoming one-third the size of the entire uterus. During childhood, the uterus usually lies in the midplane position. Later stages in pubertal development primarily affirm the myometrium, which is a reflection of response to ovarian hormonal stimulation. The endometrium further develops after onset of secondary sex characteristics with resultant menstruation (Table 2.1).
