REVIEW
Scott D Lundy, Edmund S Sabanegh
Despite being first described two thousand years ago, the varicocele remains a controversial multifaceted disease process with numerous biological consequences including infertility, hypogonadism, and chronic orchidalgia. The underlying mechanisms remain poorly understood and likely include hypoxia, oxidative stress, hyperthermia, anatomical aberrations, and genetics as primary components. Despite a high prevalence amongst asymptomatic fertile men, varicoceles paradoxically also represent the most common correctable cause for male infertility...

Disorders of sex development (DSD) consist of a wide range of conditions involving numerous genes. Nevertheless, about half of 46,XY individuals remain genetically unsolved. GATA4 gene variants, mainly related to congenital heart defects (CHD), have also been recently associated with 46,XY DSD. In this study, we characterized three individuals presenting with 46,XY DSD with or without CHD and GATA4 variants in order to understand the phenotypical variability. We studied one patient presenting CHD and 46,XY gonadal dysgenesis, and two patients with a history of genetically unsolved 46,XY DSD, also known as male primary hypogonadism...

Testosterone is indispensable for sexual development and maintaining male characteristics, and deficiency of this hormone results in primary or late-onset hypogonadism (LOH). Testosterone is primarily produced in Leydig cells, where autophagy has been reported to be extremely active. However, the functional role of autophagy in testosterone synthesis remains unknown. In this study, we show that steroidogenic cell-specific disruption of autophagy influenced the sexual behavior of aging male mice because of a reduction in serum testosterone, which is similar to the symptoms of LOH...

Background: Patients receiving androgen deprivation therapy experience secondary hypogonadism, associated bone loss, and increased fracture risk. It has been shown that tocotrienol from Bixa orellana (annatto) prevents skeletal microstructural changes in rats experiencing primary hypogonadism. However, its potential in preventing bone loss due to androgen deprivation therapy has not been tested. This study aimed to evaluate the skeletal protective effects of annatto tocotrienol using a buserelin-induced osteoporotic rat model...

Steroidogenic acute regulatory protein ( STAR ) is a key protein for the intracellular transport of cholesterol to the mitochondrium in endocrine organs (e.g. adrenal gland, ovaries, testes) and essential for the synthesis of all steroid hormones. Several mutations have been described and the clinical phenotype varies strongly and may be grouped into classic lipoid congenital adrenal hyperplasia (LCAH), in which all steroidogenesis is disrupted, and non-classic LCAH, which resembles familial glucocorticoid deficiency (FGD), which affects predominantly adrenal functions...

<br>Background: Male testosterone levels decline by 1% per year from the age of 40yrs. Whilst a primary testicular deficit occurs, hypothalamic or pituitary dysregulation may also coexist. This study aimed to compare the hypothalamic response to kisspeptin and the pituitary response to GnRH of older men with those of young men. METHODS: Following 1 hour of baseline sampling, healthy older men (n=5, mean age 59.3±2.9yrs) received a 3 hour intravenous infusion (IVI) of either: vehicle, kisspeptin-54 0...

Approximately 40% of middle-aged men exhibit symptoms of late-onset hypogonadism (LOH). However, the mechanism of androgen deficiency is still currently unclear. As shown in our previous studies, the SET protein is expressed in testicular Leydig cells and ovarian granule cells. This study was designed to investigate the effect of the SET protein on androgen production in Leydig cells. The AdCMV/SET and AdH1siRNA/SET adenoviruses were individually transduced into a cultured mouse Leydig cell line (mLTC-1) with or without human chorionic gonadotropin (HCG) stimulation in vitro...

Several mutations in the gene encoding apolipoprotein AI (apoAI) have been described as a cause of familial amyloidosis. Individuals with apoAI-derived (AApoAI) amyloidosis frequently manifest with liver, kidney, laryngeal, skin and myocardial involvement. Although primary hypogonadism (PH) is considered almost pathognomonic of this disease, until now, primary adrenal insufficiency (PAI) has not been described as a common clinical feature. Here, we report the first kindred with AApoAI amyloidosis in which PAI is well-documented...

In the case of primary male hypogonadism (HG), only testosterone (T) replacement therapy (TRT) is possible whereas when the problem is secondary to a pituitary or hypothalamus alteration both T production and fertility can be, theoretically, restored. We here systematically reviewed and discussed the advantages and limits of medications formally approved for the treatment of HG. Areas covered: Data derived from available meta-analyses of placebo controlled randomized trials (RCTs) were considered and analyzed...

Hypogonadal men may experience intense vasomotor symptoms, and vasomotor sweating can occasionally be associated with profound fluid losses. We describe a 37-year-old male, who exhibited persistent hypovolaemic hypernatraemia that was challenging to treat despite a continuous high fluid input (>4-5 L/day). He was noted to have drenching sweats and normochromic anaemia. He had recent traumatic head injury, which resulted in neurocognitive dysfunction, so pituitary function tests were done which showed primary hypogonadism...

Long-term testosterone replacement therapy is mainly monitored by trough levels of serum testosterone (S-T), while urinary testosterone (U-T) is used by forensic toxicology to evaluate testosterone doping. Testosterone in saliva (Sal-T) may provide additional information and simplify the sample collection. We aimed to investigate the relationships between testosterone measured in saliva, serum and urine during standard treatment with 1,000 mg testosterone undecanoate (TU) every 12th week during 1 year. This was an observational study...

REVIEW
Ryan C Petering, Nathan A Brooks
Testosterone therapy is increasingly common in the United States, and many of these prescriptions are written by primary care physicians. There is conflicting evidence on the benefit of male testosterone therapy for age-related declines in testosterone. Physicians should not measure testosterone levels unless a patient has signs and symptoms of hypogonadism, such as loss of body hair, sexual dysfunction, hot flashes, or gynecomastia. Depressed mood, fatigue, decreased strength, and a decreased sense of vitality are less specific to male hypogonadism...

Swyer syndrome is a pure gonadal dysgenesis associated with a 46 XY karyotype and primary amenorrhea in a phenotypic female. Individuals in this syndrome are at an increased risk for development of gonadal malignancies. Swyer syndrome (gonadal dysgenesis) running in families is rare event and few such scenarios were reported in the literature. Here we are presenting this rare entity involving three affected siblings born to a non-consanguineous couple. Index case - A 23-year-old female with primary amenorrhea is presented with a mass per abdomen...
