Introduction: Estrogen has positive effects on bone mineral density (BMD), in particular in trabecular bone through inhibition of bone resorption. Testosterone increases bone size, but the effect on BMD is less clear. Cross-sex hormonal treatment (CSHT) in transgender individuals can affect BMD. Therefore, the aim of this study is to investigate effects of CSHT on BMD during the first year of treatment in male-to-female (MtFs) and female-to-male (FtMs) transgender persons....

Background: Persistent vaginal bleeding can be psychologically stressful and incongruent with gender identity in transgender men (assigned female at birth with male gender identity). Previous studieshave cross-sectionally described amenorrhea in cohorts of transgender men on intramuscular or subcutaneous testosterone injections. It remains uncertain which testosterone preparations most effectively suppress vaginal bleeding and when amenorrhea occurs after testosterone initiati...

Introduction: The insulin tolerance test (ITT) is the gold standard method to assess GH and/or ACTH deficiency. Safety concerns with the use of this test were raised more than 20 years ago from overtreatment of hypoglycaemia and consequent cerebral oedema, resulting in some centres using alternative tests. We have re-appraised use of the ITT in a contemporary setting and evaluated: i) timing of the glucose nadir, ii) time to resolution of hypoglycaemia, iii) adverse events and...

Within the synovium of patients with rheumatoid arthritis (RA), synovial fibroblasts generate active corticosteroids through expression of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1). In vitro, this enzyme is strongly up-regulated by pro-inflammatory cytokines such as tumour necrosis factor α (TNFα) and IL1β. In this study, we determined the relationship between inflammation and global 11β-HSD1 activity in vivo, in a clini...

Introduction: Male-to-female gender identity disorder (MtF GID) is a complex phenomenon that could be better evaluated by using a dimensional approach.Aim: To explore the aggregation of clinical manifestations of MtF GID in order to identify meaningful variables describing the heterogeneity of the disorder.Methods: A consecutive series of 80 MtF GID subjects (mean age 37±10.3 years), referred to the interdepartmental Center fo...

Introduction: Childhood maltreatment is quite common and constitutes a non-specific risk factor for a range of different emotional and behavioural problems during lifespan. It has been demonstrated that sexual minorities are at higher risk of maltreatment and abuse, and a high proportion of transsexual subjects reports childhood maltreatment.Aim: To evaluate the prevalence of reported childhood maltreatment in a clinical sample of patients with male to f...

Introduction: Although penile blood flow (PBF) has been recommended as an additional diagnostic test in identifying erectile dysfunction (ED) patients at risk for latent cardiovascular disease, no study has ever assessed the possible association of PBF and the relational component of sexual function with incident major cardiovascular events (MACE).Aim: The aim of this study is to investigate whether severity of ED, PBF and other factors related to a coup...

Introduction: Although testosterone has been suggested to play a protective role against the development of atherosclerosis, studies demonstrating an association between low testosterone, and incident major adverse cardiovascular events (MACE) are scanty in the general population and absent in subjects with erectile dysfunction (ED). The aim of this study is to investigate whether low testosterone in subjects with ED predict incident fatal or non fatal MACE.<p class="abste...

Introduction: While the association of Klinefelter’s syndrome (KS) with infertility is well known, very few investigations have evaluated the prevalence of sexual dysfunction in KS. The aim of the present study is to systematically analyse the prevalence of KS in a consecutive series of adult male patients consulting for sexual problems and to investigate its specific correlates.Methods: Among a consecutive series of 1386 patients (mean age 48.9&#17...

Objectives: Erectile dysfunction (ED) is often associated with a wide array of psychiatric symptoms, although few studies systematically address their specific association with ED determinants. Aim of this study is to explore the relationship between ED and different psychopathological symptoms.Design and methods: A consecutive series of 1388 (mean age 51±13 years) male patients with ED was studied. Several hormonal and biochemical parameters were i...
