Introduction: Hyponatremia is the most common electrolyte disorder in clinical practice, and evidence to date indicates that severe hyponatremia is associated with increased morbidity and mortality. The aim of our study was to perform a comprehensive meta-analysis that included all the published studies that compared mortality rates in subjects with or without hyponatremia of any degree.Methods: An extensive Medline, Embase, and Cochrane search was perfo...

Introduction: Metabolic syndrome (MetS) is often associated with male hypogonadism. The role of testosterone replacement therapy (TRT) in MetS has not been completely clarified.To systematically analyse the relationship between androgen levels and MetS we performed a review and meta-analyses of available prospective and cross-sectional studies. A specific meta-analysis on the metabolic effects of TRT in available randomised clinical trials (RCTs) was als...

Introduction: Previous clinical studies on effect of statins treatment on testosterone levels have produced mixed results. The aim of the present study is to evaluate the association between statin therapy and hormonal parameters in a large series of subjects seeking medical care at our Unit for ED.Methods: A consecutive series of 3484 (mean age 51.6±13.1 years) patients with ED was studied.Several hormonal and biochemical par...

Introduction: Although it is well established that all the aspects of male reproduction are hormonally regulated, the endocrine control of the ejaculatory reflex is still not completely clarified. Sex steroids, thyroid and pituitary hormones (oxytocin and prolactin) have been proposed to control the ejaculatory process at various levels, however, only a few reports are currently available. The aim of the present study is to evaluate the contribution of testosterone, TSH and pr...

Objectives: The physiological role of prolactin in male sexual function has not been completely clarified. Aim of this study is the assessment of clinical features and of conditions associated with hyperprolactinemia in male patients consulting for sexual dysfunction.Design and methods: A consecutive series of 2146 (mean age 52.2±12.8 years) male patients with sexual dysfunction was studied. Several hormonal and biochemical parameters were studied a...

Objectives: Type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS) are characterized by insulin resistance and often associated with male hypogonadism. To discriminate the specific contribution of T2DM and MetS to male hypogonadism.Design and methods: A consecutive series of 1134 (mean age 52.1±13 years) male patients with sexual dysfunction was studied. Several hormonal and biochemical parameters were studied along with ANDROTEST, a 12-item ...

Epididymis (epi) is a sex steroid-sensitive duct provided with spontaneous motility, allowing sperm transport. We previously demonstrated that human epi expresses a high abundance of mRNA for ER-alpha and ER-beta. We demonstrated that in epi estrogens up-regulate either oxytocin (OT) responsiveness, acting at the receptor level, and responsiveness to endothelin-1 (ET-1), another well-known stimulator of epididymal motility. However, we did not find any significant change eithe...

Objectives: The aim of present study was to verify possible differences in the prevalence of vasculogenic ED and hypogonadism comparing two distinct new definitions of MetS, as National Cholesterol Education Program-Third Adult Treatment Panel (NCEP-ATPIII) and International diabetes Federation (IDF) in patients with sexual dysfunction.Methods: Several hormonal, biochemical and instrumental (penile doppler ultrasound) parameters were studied. ANDROTEST S...

Objectives: Detecting hypogonadism is crucial in patients with sexual dysfunctions because hypogonadism can have a causal role for them and testosterone (T) substitution represents a milestone for the therapy. At present, three different inventories have been developed for screening of hypogonadism in aging male. All these instruments demonstrated a good sensitivity but low specificity. No inventories are available for the screening of hypogonadism in patients with sexual dysf...

Objectives: To date it is not clear to which extent a clinical, or even a subclinical, sexual dysfunction in the female partner might associate with erectile dysfunction (ED) in the male partner. The present study is aimed at the assessment of clinical features of ED associated with relational disturbances.Methods: In a consecutive series of 1140 male subjects reporting a stable couple relationship we evaluated the impact of relational factors, as assess...
