Background: Hypovitaminosis D represents at present a worldwide public health problem. Recent studies have demonstrated the pleiotropic effects of vitamin D, in addition to its known actions on calcium-phosphorus metabolism. Among the several non-skeletal effects, a potential anti-inflammatory and immunomodulatory action has been suggested. Vitamin D deficiency has been reported in several chronic conditions associated with increased inflammation and deregulation of the immune...

Introduction: Physical exercise exerts several effects on endocrinological homeostasis and, in particular, sprint exercise elicits the largest testosterone response per unit of work, while in response to prolonged endurance exercise testosterone levels will typically decline. In contrast to a large amount of paper about the modification of testosterone during physical exercise few study evaluated how DHT was influenced by a single bout of aerobic exercise.<p class="abstext...

Background: Many testosterone (T) formulations are now available for treating male hypogonadism. Intramuscular injectable T esters and transdermal T gel are the most commonly used in clinical practice. Transdermal T gel is often preferred by patients due to ease of use and reduced fluctuations in serum T compared to injectable esters. A daily dosage of 20 mg – 80 mg mimicking circadian profile is recommended to adequately treat hypogonadal men.Aim: ...

Worldwide numerous active individuals take phosphodiesterase type 5 inhibitors (PDE-5i), furthermore, to our knowledge, the effects of these drugs on hormone secretion has not been adequately investigated. In particular, considering that a) PDE-5i influence NO bioavailability, b) NO is one of the mediators of the hypothalamus–pituitary–adrenal (HPA) axis response to stress, and, c) physical exercise-related stress activate HPA axis, we investigated whether PDE-5i inf...

Background: Varicocele repair is often suggested to improve reproductive outcomes, but there is no clear indications on which subjects are more likely to benefit from treatment. We assessed spermatogenetic and endocrine function of the testis in a population of young subjects with a 12-month follow-up following percutaneous treatment.Methods: We retrospectively reviewed data from 77 young patients (mean age 23.3 years, range 18–35) followed in our c...

The aim of the present study was to evaluate the phenotype of PHPT, the adherence to International Guidelines and the rate of surgical cure of PHPT in Italy. From January 2014–January 2016, we conducted a prospective, multicenter (n=29 endocrine tertiary referral centers) study on patients with PHPT, recording clinical and biochemical data, parathyroid imaging and therapy choice at baseline and at last follow-up. The study group included 604 patients with PHPT, w...
