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: Intracavernous alprostadil injection (ICI) test has been considered useless in assessing the vascular status of subjects with erectile dysfunction (ED).Aim: To analyze the clinical correlates of ICI test in patients with ED and to verify the value of this test in predicting major adverse cardiovascular events (MACE).Methods: A consecutive series of 2,396 men (mean age 55.9±11.9 years) attending our outpatient cli...

Introduction: The category of impaired fasting glucose (IFG) denotes a state of non-diabetic hyperglycemia, considered a risk factor of the further development of diabetes mellitus (DM) and cardiovascular (CV) diseases.Aim: The aim of the present study is to evaluate the impact of IFG on sexual health in men. In addition its effect on CV morbidity and mortality will also be addressed.Methods: A consecutive series of 3451 men (mean ...

Prepuberal-onset HH (PRHH) and postpuberal-onset HH (PSHH) men required GnTh by means of administration of both the β human chorionic gonodadotropin (ηHCG) and the FSH to induce a complete spermatogenesis. However, the response to GnTh is always unpredictable concerning either the effectiveness or the duration of the therapy. Consequently, different studies have been carried out to identify clinical and biochemical markers that can be useful to predict the effectiven...

Introduction: We previously developed and validated a structured interview (SIEDY) dealing with the organic (scale 1), relational (scale 2) and intrapsychic (scale 3) components of erectile dysfunction (ED). The aim of the present study is to identify a pathological threshold for SIEDY scale 3 and to analyze scale 3 score with biological and psychological correlates in subjects with sexual dysfunction.Method: A pathological threshold of SIEDY scale 3 sco...

Introduction: Previous studies concerning ultrasound evaluation of the seminal vesicles (SV) have been performed on a limited series of subjects, taking into consideration few parameters, often only before ejaculation and without assessing sexual abstinence of the patients. The aim of this study is to evaluate the volume and the emptying characteristics of the SV and their possible correlations with scrotal and transrectal ultrasound features.Methods: Th...

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...
