Prevalence of hypogonadism in men with cancer has been reported between 40% and 90%, which is significantly higher than in the general population. Hypogonadism is likely to affect the quality of life in these patients by contributing to non-specific symptoms, including decreased energy, anorexia, sarcopenia, weight loss, depression, insomnia, fatigue, weakness, and sexual dysfunction. Pathogene...

The male hypogonadism-related bone mass loss is often under diagnosed. Peak bone mass is severely affected if the hypogonadism occurs during puberty and is left untreated. We present an interesting; almost bizarre case of a male with non-functional testes early during childhood and undiagnosed and untreated hypogonadism until his fifth decade of life. Forty six year male is referred for goitre,...

Androgenic hormones are important in normal embryonic development and maintenance of the structural integrity of the penis. This structural integrity is vital in the physiology of penile erection. Its alteration may therefore lead to functional impairment resulting in erectile dysfunction as seen in hypogonadic conditions. The link between hypogonadism and erectile dysfunction is partly anatomi...

BACKGROUND We characterized the spectrum and etiology of hypogonadism in a cohort of Prader-Willi syndrome (PWS) adolescents and adults. METHODS Reproductive hormonal profiles and physical examination were performed on 19 males and 16 females ages 16-34 years with PWS. Gonadotropins, sex-steroids, inhibin B (INB) and anti-Mullerian hormone (AMH) were measured. We defined 4 groups according to...

BACKGROUND Hormonal derangements potentially contribute to the diagnosis of infertility in over 60%-70% of couples investigated. Use of hormonal and antihormonal agents has achieved great success in the treatment of male infertility. Our aim was to investigate the prevalence of hormonal abnormalities in males diagnosed with infertility. METHODS Males diagnosed clinically with infertility and ...

Age-related bone loss in men is a poorly understood phenomenon, although increasing data on the pathophysiology of bone in men is becoming available. Most of what we know on bone pathophysiology derives from studies on women. The well-known association between menopause and osteoporosis is far from been disproven. However, male osteoporosis is a relatively new phenomenon. Its novelty is in part...

PURPOSE Studies that analyze the levels of osteoprotegerin (OPG) or receptor activator of nuclear factor kappa B ligand (RANKL) in hypogonadal men, the majority of whom have prostate cancer or are undergoing androgen-deprivation therapy, are few and inconclusive. METHODS 81 men aged 69.3 ± 0.8 years (39 men with late-onset hypogonadism and 42 age-matched controls) were recruited. Serum levels...

Most inborn errors of metabolism (IEM) are recessive, genetically transmitted diseases and are classified into 3 main groups according to their mechanisms: cellular intoxication, energy deficiency, and defects of complex molecules. They can be associated with endocrine manifestations, which may be complications from a previously diagnosed IEM of childhood onset. More rarely, endocrinopathies ca...

OBJECTIVES Opioids have been used for medicinal and analgesic purposes for centuries. However, their negative effects on the endocrine system, which have been known for some times, are barely discussed in modern medicine. Therefore, we conducted a systematic review of the impact of opioids on the endocrine system. METHODS A review of the English language literature on preclinical and clinical...

Clomiphene citrate (CC) is a selective estrogen receptor modulator and antagonist. It was introduced into clinical medicine in 1967 for the treatment of female infertility. CC has also been explored off-label use male infertility hypogonadal symptoms. We want to comment discuss medical literature on its contribution hypogonadism. The main goal commentary mechanism action when it can be used hyp...
