BACKGROUND: This is an update of the 2008 British Society for Sexual Medicine (BSSM) guidelines. AIM: To provide up-to-date guidance for U.K. (and international) health care professionals managing male sexual dysfunction. METHODS: Source information was obtained from peer-reviewed articles, meetings, and presentations. A search of Embase, MEDLINE, and Cochrane Reviews was performed, covering the search terms "hypogonadism," "eugonadal or hypogonadism or hypogonadal or gonadal," and "low or lower testosterone," starting from 2009 with a cut-off date of September 2017...

<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...

BACKGROUND: Testosterone, the most important androgen produced by the testes, plays an integral role in male health. Testosterone levels are increasingly being checked in primary healthcare as awareness of the risks of male hypogonadism grows. AIM: To investigate what tests are performed to screen for hypogonadism and to exclude secondary hypogonadism. DESIGN AND SETTING: All participants attended general practices in the UK. METHODS: Data search was performed using the EMIS®: clinical database (provider of the majority of GP operating systems in Cheshire)...

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...

The objective of the current study was to measure the adherence of guideline-based evaluation and treatment of hypogonadism by medical specialty. A retrospective review was performed analyzing patients from a single academic institution within the past 10 years. The cohort of 193 men was grouped according to medical specialty of the diagnosing physician (50 urology, 49 primary care, 44 endocrinology, and 50 HIV medicine). Adherence to guidelines was assessed using the Endocrine Society's criteria. Primary care patients were older compared to the rest of the cohort ( p < ...

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...

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...

AIM: Although "late onset hypogonadism", a condition that includes low testosterone and symptoms, is common in men over the age of 40 years, diagnosis is not clear cut amongst non-specialists. It is the aim of this review to provide an up to date picture of how this state should be diagnosed and managed. METHODS: We aim to describe how primary and secondary hypogonadism should be excluded before the diagnosis of late onset hypogonadism is reached. As laboratory testosterone measurements are essential the current pitfalls such as inappropriate sample collection and the use of population derived reference ranges are expanded...

Recent studies reveal that hypogonadism with low serum androgen levels is associated with advanced cancer and induction of most cancer-related symptoms. We designed an ARTFORM study to evaluate the efficacy of androgen replacement therapy in male advanced cancer patients. The ARTFORM study is an investigator-initiated, randomised controlled trial comparing intramuscle injection of testosterone enanthate with non-administration in male advanced cancer patients with non-curative locally advanced or metastatic lesions...

CONTEXT: Previous animal and human research suggests that testosterone has anti-nociceptive properties. Castration in male rodents increases pain perception which is reversed by testosterone replacement. Pain perception also improves in hypogonadal men with testosterone therapy. However, it remains unclear whether androgen deprivation therapy (ADT) in men with prostate cancer (PCa) is associated with an increase in pain perception. METHODS: Thirty-seven men with PCa about to undergo ADT with leuprolide acetate (ADT group) were followed prospectively for 6 months to evaluate changes in clinical and experimental pain...
