A role for leptin deficiency as a fundamental mechanism of HA was clearly established by the observation that administration of amsnorrhea to eight women with persistent FHA although near-normal or normal body weight for height resulted in ovulatory menses in three of eight and evidence of follicular growth in two more HH may result from either absent or inadequate hypothalamic GnRH secretion or failure of pituitary gonadotropin secretion.

Polycystic ovary syndrome PCOS is the most common cause primary amenorrhea hyperandrogenic chronic anovulation. Thus, in a setting where hirsutism is the chief clinical concern, the presence of regular menstrual cycles may help differentiate PCOS from CAH women; however, if the clinical presentation involves irregular menses, there does not seem to be a possibility for selective screening of patients, and the diagnostic algorithm for PCOS should still be followed by ruling out CAH.

Menstrual irregularity: a possible clinical marker of metabolic dysfunction in women with class III obesity. In contrast, newborn girls have no obvious abnormal findings that might provide clues to the diagnosis. The early presentation of the hypogonadism, manifesting as primary amenorrhea, and the association with nonreproductive phenotypes ogival palate and bone abnormalities contributed to the hypothesis of a congenital defect in this apparently sporadic case of IHH. Each individual stressor was not significantly able to induce FHA in the animals studied; however, the combination of all three stressors caused abnormal cycles in seven of 10 animals defined as cycles that were shorter than 25 d or longer than 44 d, or anovulatory based on every other day progesterone levels.
