Isolated hypogonadotropic hypogonadism (IHH) is characterized by complete or partial failure of pubertal development due to impaired secretion of luteinizing.

CHH is a genetically heterogenous disorder with cases reported as being X-linked, recessive and autosomally inherited.

From Wikipedia, the free encyclopedia. Call your provider if: The KAL1 gene encodes anosmin-1an extracellular adhesion molecule that plays hipogonadptrofico role in GnRH neuronal migration and adhesion.

GnRH neurons are derived from the olfactory placode and migrate into the central nervous system CNS during embryonic development. Leticia Ferreira Gontijo Silveira.

The production of sex steroids forms a negative feedback loop acting on both the anterior pituitary and hypothalamus causing a pulsatile secretion of GnRH. You are a man and you have decreased interest in sex. Diseases of the endocrine system E00—E35— Physiology and disorders of puberty.

This prevents normal sexual maturity in children and normal function of fe,enino testicles or ovaries in adults. Raquel Barrio 13 Estimated H-index: Han hipogonxdismo Estimated H-index: Julia Prague 7 Estimated H-index: Chou 11 Estimated H-index: Hypogonadotropic hypogonadism HH or secondary hypogonadism is defined as a clinical syndrome that results from gonadal failure due to abnormal pituitary gonadotropin levels.

Combined this causes the secretion of gonadal sex steroids and the initiation of folliculogenesis and spermatogenesis.


Dopamine binds to D2 receptors on lactotrophs within the anterior pituitary [6] This results in the inhibition of secretion of prolactin resulting in less direct and indirect inhibition of GnRH secretion. Large-scale genomic analyses yipogonadismo reproductive aging to hypothalamic signaling, breast cancer susceptibility and BRCA1-mediated DNA repair.

Day 22 Estimated H-index: The goal for HH therapy is to induce pubertal development, sexual function, fertility, bone health, and psychological wellbeing [3] Testosterone therapy for males and estradiol therapy for females is used to improve genital development, develop secondary sexual characteristics, allow for the growth and closure of the epiphyseal plateas well as improving sexual function.

Hormonal Causes of Delayed Puberty. GnRH is released by hypothalamic neuroendocrine cells into the hypophyseal portal system acting on gonadotrophs in the anterior pituitary.

The mechanism of prolactin induced inhibition of GnRH release is poorly understood. Tolulope Shonibare 1 Estimated H-index: Several congenital and acquired causes, including functional and organic forms, have been associated with this condition.


Mutations of KAL1 are mostly nucleotide insertion or deletion causing frame shifts in the translation of anosmin-1 resulting in a faulty protein. Some people ffmenino this condition also have anosmia loss of the sense of smell. The prevalence difference between male and females is unknown, and is likely to be underreported for females.
