Hypogonadotropic Hypogonadism Revisited [PDF]
Clinics, 2013 Impaired testicular function, i.e., hypogonadism, can result from a primary testicular disorder (hypergonadotropic) or occur secondary to hypothalamic-pituitary dysfunction (hypogonadotropic).

Hypogonadism and Cryptorchidism [PDF]
Frontiers in Endocrinology, 2020 Congenital cryptorchidism (undescended testis) is one of the most common congenital urogenital malformations in boys. Prevalence of cryptorchidism at birth among boys born with normal birth weight ranges from 1.8 to 8.4%. Cryptorchidism is associated with a risk of low semen quality and an increased risk of testicular germ cell tumors.

Hypogonadism and diabetes [PDF]
International Journal of Impotence Research, 2003 Clinicians have been aware of the increased prevalence of low testosterone levels in patients with type II diabetes for several years, but how these two conditions are associated is difficult to determine. Older age and obesity may be factors, as both are associated with type II diabetes and both decrease testosterone levels.

Mechanisms of Central Hypogonadism [PDF]
International Journal of Molecular Sciences, 2021 Reproductive function depends upon an operational hypothalamo–pituitary–gonadal (HPG) axis. Due to its role in determining survival versus reproductive strategies, the HPG axis is vulnerable to a diverse plethora of signals that ultimately manifest with Central Hypogonadism (CH) in all its many guises.

Prevalence and Risk Factors for Hypogonadism in Male Patients with Type 2 Diabetes Mellitus
Biomedical and Biotechnology Research Journal, 2023 Background: Type 2 diabetes mellitus (DM) can develop many complications, including hypogonadism, the prevalence of which is largely unknown. Male hypogonadism is an endocrine disease characterized by low-serum testosterone levels and is closely related ...

BMC Geriatrics, 2010 The Massachusetts Male Aging Study [1] shows that male hormones decrease with aging. This is due to some testicular and hypothalamic-pituitary defects. Impaired hypothalamic secretory reserve, resulting in a reduced and chaotic secretion of GnRH, reduced pituitary response to GnRH, resulting in an increased but irregular LH pulse frequency [2] With ...

Pituitary imaging findings in pediatric patients with idiopathic hypogonadotropic hypogonadism
Endocrine Regulations, 2023 Objective. Idiopathic hypogonadotropic hypogonadism in children is a disease leading to a puberty absence. Some hypothalamic and pituitary defects cause hypogonadotropic hypogonadism.

Genetics of hypogonadotropic hypogonadism [PDF]
Translational Andrology and Urology, 2021 Male congenital hypogonadotropic hypogonadism (CHH) is a heterogenous group of genetic disorders that cause impairment in the production or action of gonadotropin releasing hormone (GnRH). These defects result in dysfunction of the hypothalamic-pituitary-gonadal hormone axis, leading to low testosterone levels and impaired fertility.

Hypogonadism and renal failure: An update
Indian Journal of Urology, 2015 The prevalence of both hypogonadism and renal failure is increasing. Hypogonadism in men with renal failure carries with it significant morbidity, including anemia and premature cardiovascular disease.

Male hypogonadism. Part I: Epidemiology of hypogonadism [PDF]
International Journal of Impotence Research, 2005 Male hypogonadism is a frequent and potentially undertreated condition. A number of longitudinal epidemiologic studies, including the Baltimore Longitudinal Study of Aging, the New Mexico Aging Process Study, and the Massachusetts Male Aging Study, have demonstrated age-related increases in the likelihood of developing hypogonadism.
