Androgen deficiency occurs frequently in men with human immunodeficiency virus (HIV) infection. Antiretroviral treatments had reduced the prevalence of male hypogonadism. The pathogenesis of testosterone (T) deficiency in HIV is multifactorial. Several mechanisms have been proposed; among them, drugs, fat redistribution, and a poor health status could explain the mechanism leading to gonadotrop...
While the contributing role of testosterone to bone health is rather modest compared to other factors such as estradiol levels, male hypogonadism is associated with low bone mass and fragility fractures. Along with stimulating physical puberty by achieving virilization and a normal muscle mass and improving psychosocial wellbeing, the goals of testosterone replacement therapy in male hypogonadi...
Hypoestrogenism is referred to lower than normal serum levels of estrogen. Hypoestrogenism can be regarded as typical and physiological in postmenopausal women. However, hypoestrogenism which oocurs in young women is related to pathological background. There are two groups of disorders in young women related to hypoestrogenism: hypogonadotropic hypogonadism and hypergonadotropic hypogonadism. H...
Several testosterone preparations are used in the treatment of hypogonadism in the ageing male. These therapies differ in their convenience, flexibility, regional availability and expense but share their pharmacokinetic basis of approval and dearth of long-term safety data. The brevity and relatively reduced cost of pharmacokinetic based registration trials provides little commercial incentive ...
Hypogonadism or Testosterone Deficiency (TD) in adult men as defined by low levels of serum testosterone accompanied by characteristic symptoms and/or signs as detailed further on can be found in long-recognized clinical entities such as Klinefelter syndrome, Kallmann syndrome, pituitary or testicular disorders, as well as in men with idiopathic, metabolic or iatrogenic conditions that result i...
The causal association of childhood obesity and hypogonadotrophic hypogonadism needs to be studied to unravel the cause and effect relationship between the two conditions. The relationship of hypogonadism to the Metabolic Syndrome (MetS) remains valid even when using different definitions of MetS, and following the patients prospectively for over 10 years. This is a case of 19 years male who pr...
Federal University of São Paulo (UNIFESP), São Paulo SP, Brazil: Department of Neurology and Neurosurgery; Department of Endocrinology; Department of Ophthalmology. The association between cerebellar ataxia and hypogonadism was first described by Gordon Holmes in 1907. It represents a highly heterogenous syndrome with insidious onset. The hypogonadism of most patients with Gordon Holmes syndrom...
Familial cerebellar ataxia with hypogonadotrophic hypogonadism is a rare condition. Two affected siblings in a sibship of three were studied and found to have low plasma gonadotrophin levels. No rise in gonadotrophin levels was demonstrable after repeated stimulation with LHRH. The pattern of TSH and prolactin responses to TRH stimulation suggest hypothalamic dysfunction. The results clearly id...
Type I Chiari malformations consist of herniation of the cerebellar tonsils through the foremen magnum and present with a variety of symptoms and signs described previously but hemiathrophy of extremities and hypothalamic hypogonadism are not characteristic findings. Hemiathrophy of extremities has been reported in just one case, and to our knowledge hypothalamic hypogonadism has not been repor...
Anumber of syndromes have been described in which hypogonadotrophic hypogonadism is associated with multiple somatic and neurological anomalies such as tall stature, anosmia, ataxia, mental retardation, and choroidal dystrophy. The large number of syndromes indicates the considerable clinical heterogeneity associated with hypogonadotrophic hypogonadism. In this report, we describe an unusual co...
