Answer

Absence of spontaneous menstruation before age 16 years is an indication for a careful review of systems. The menstrual cycle should be viewed as a vital sign. Inquiring about other aspects of growth and pubertal development is important. An absence of any breast development or pubertal growth spurt by age 13-14 years in girls is distinctly abnormal and requires investigation.

Breast development, pubertal growth spurt, and adrenarche are delayed or absent in girls with hypothalamic pituitary failure. A distinguishing factor in the case of isolated ovarian insufficiency or failure is that adrenarche occurs normally, while estrogen-dependent breast development and the pubertal growth spurt are absent or delayed.
