Background: The recognition of the erectile dysfunction (ED) pathogenesis is essential to identify the appropriate ED management. Since vascular ED (vED) could be a manifestation of a systemic arterial damage, the watershed in the ED diagnostic framework is the discrimination between psychological (pED) and vED. However, reliable tools to directly diagnose pED are currently lacking.Aim of the study: To identify which parameters could predict pED. Moreove...

Background: Persons with assigned either male (AMAB) or female (AFAB) sex at birth might wish to obtain feminization or masculinization, respectively. To this purpose, hormonal treatment with sex hormones must be tailored to each subject. Several studies and the European Society of Endocrinology guidelines tried to identify the optimal hormonal treatment in both AMAB and AFAB subjects. However, the clinical management in the long term follow-up remains challenging. Many treatm...

Background: Patients with CHH and KS have eunuchoid body proportions of the skeleton compared to normal male subjects, characterized by tall stature, and reduced upper-to-lower segment ratio (U/l). Vice versa, steroids exposure deeply differs between CHH and KS at puberty, with both testosterone and estradiol being very low only in CHH. At present, body skeletal proportions comparison between CHH and KS is not available.Aim: To compare anthropom...

Introduction: Male idiopathic infertility represents a therapeutic challenge for physicians, since a targeted aetiological treatment does not exist. Several hormonal and non-hormonal therapies have been proposed so far to increase pregnancy rates. Among hormonal therapies, exogenous follicle-stimulating hormone (FSH) administration shows the most convincing physiological rationale in the face of a clinical efficacy below expectations. Indeed, from evidences available in the li...

Background: Erectile dysfunction (ED) represents the most frequent sexual dysfunction. Among several possible ED aetiologies, vascular ED (vED) presents the greatest implications for global individual health, resulting an early hallmark of cardiovascular diseases. Indeed, vED was demonstrated associated with a 1.25 times greater risk of developing major cardiovascular diseases. Alongside cardiovascular aspect, the evaluation of patients health, measured by the comorbidities nu...

Objective: Environmental rhythmicity seems able to affect the hypothalamic-pituitary-gonadal axis in animals, but the extent of its influence in humans is still controversial. This study was designed to evaluate seasonal fluctuations of the main hormones involved in the hypothalamic-pituitary-gonadal axis in men, using a big data approach.Methods: An observational, retrospective, big data trial was carried out, including all testosterone, luteinizing hor...

Background: Environmental rhythmicity seems able to affect the hypothalamic-pituitary-gonadal axis in animals to achieve reproductive advantages. However, conflicting results were obtained when assessing the environmental-dependent rhythmicity on reproductive hormone secretion in humans.Aim of the study: This study was designed to evaluate seasonal fluctuations of the main hormones involved in the hypothalamic-pituitary-gonadal axis in men, using a big d...

Over the last decade 824 pituitary tumours have been removed in our centre. Of these, 114 (13.8%) were corticotroph adenomas. We present four unusual cases of corticotroph adenoma showing transition from Cushing’s disease to a hormonally inactive adenoma (case 1 and 2) or vice versa (case 3 and 4).Case 1: A 51-year-old man was admitted with a 2-year history of weight gain, arterial hypertension and chiasmatic syndrome. Cushing’s disease (CD) du...

Introduction: In order to study the effect of age and testosterone on sleep related erections, we enrolled 209 men (122: age 30–49 years; 87: age over 50 years), including mild and severe hypogonadal subjects (129) and eugonadal subjects (80).Subjects and methods: The subjects were assigned to four groups, according to their testosterone serum levels. All the subjects underwent nocturnal penile tumescence and rigidity monitoring (NPTRM). The followi...

Background: Endothelial dysfunction leads to cardiovascular complications in type 2 diabetes mellitus (T2DM), through a reduction of nitric oxide (NO)-mediated relaxation. Phosphodiesterase-5 inhibitors (PDE5i) have hemodynamic effects, improving NO levels.Aim: To investigate if long term, chronic treatment with the PDE5i Vardenafil improves systemic endothelial function in men with T2DM.Methods: A longitudinal, prospective, invest...
