Large-scale genomic analyses link reproductive aging to hypothalamic signaling, breast cancer susceptibility and BRCA1-mediated DNA repair. Mutations of KAL1 are mostly nucleotide insertion or deletion hjpogonadismo frame shifts in the translation of anosmin-1 resulting in a faulty protein. One important aspect of the HH diagnosis is that it may reflect the presence of a tumor of the hypothalamic pituitary region or even a systemic disease.

On the other hand, functional forms of HH, characterized by a transient defect in GnRH secretion, are relatively common in women, in response to significant weight loss, exercise, or stress leading to hypothalamic amenorrhea.

Several congenital hipogonadsimo acquired causes, including functional and organic forms, have been associated with this condition. Exogenous GnRH can be used as a diagnostic tool. The production of sex steroids forms a negative feedback loop acting on both the anterior pituitary and hypothalamus causing a pulsatile secretion of GnRH. Other Papers By First Author.
