Background: The concept of testosterone (T) supplementation (TS) as a new anti-obesity medication in men with testosterone deficiency syndrome (TDS) is emerging.Aim: To systematically review and meta-analyze available observational and register studies reporting data on body composition in studies on TS in TDS.Methods: An extensive Medline Embase and Cochrane search was performed including the following words: ‘testosterone&#1...

Background: The role of testosterone (T) in regulating body composition is conflicting.Aim: To meta-analyze the effects of T supplementation (TS) on body composition and metabolic outcomes.Methods: All randomized controlled trials (RCTs) comparing the effect of TS on different endpoints were considered.Results: Overall, 59 trials were included in the study enrolling 3029 and 2049 patients in TS and control gr...

Introduction: Conventional cardiovascular (CV) risk factors identify only half of subjects with incident major adverse CV events (MACE). Hence new markers are needed in high CV risk subjects, as those with erectile dysfunction (ED). A role for dynamic peak systolic velocity (D-PSV) at penile color Doppler ultrasound (PCDU) has been suggested, but it is operator-dependent and time-consuming. Flaccid penile acceleration (FPA) is a PCDU parameter that reflects PSV, the systolic r...

Introduction: Type 2 diabetes mellitus (T2DM) is often associated with male hypogonadism. The role of testosterone replacement therapy (TRT) in T2DM has not been completely clarified. To systematically analyse the relationship between androgen levels and T2DM by reviewing and meta-analyzing available prospective and cross-sectional studies. In addition, a specific meta-analysis on the metabolic effects of TRT in available randomised clinical trials (RCTs) was also performed.</...

Introduction: The role of testosterone supplementation (TS) as a possible treatment for male sexual dysfunction remains questionable. The aim of the present study is to meta-analyse data evaluating the effects of TS on male sexual function and its therapeutic synergism with the use of phosphodiesterase type 5 (PDE5i).Methods: An extensive Medline Embase and Cochrane search was performed including the following words: ‘testosterone’, ‘erect...

Ageing in men is accompanied by a decline in serum testosterone (T) levels and increased risk of cardiovascular disease, osteopenia, visceral obesity and impaired metabolism. These conditions have complex aetiologies that may share a common pro-inflammatory state. We investigated the impact of T therapy on cytokines and angiogenic factors involved in atherosclerosis and bone loss, in hypogonadal men who underwent androgen replacement. We carried out a 6 months, randomized, dou...

Background: Testosterone (T) is essential for bone health during all ages, helping to achieve a proper peak bone mass and, later, to maintain bone density and strength. Guidelines on management of male osteoporosis recommend testosterone replacement in young-adult hypogonadal to prevent bone loss and anti-resorbitive drugs in case of high fracture risk, but the role of T replacement therapy (TRT) alone in subjects with late onset hypogonadism is still the object of an intense ...

Introduction: Klinefelter syndrome (KS) is the most frequent chromosomal disorders, occurring in 1:500 to 1:1000 live male births, associated to male infertility. Although significant research has been conducted, KS remains frustratingly underdiagnosed with a remarkable portion of cases being unidentified. Under diagnosis may be due to man’s hesitancy about seeking medical counseling, low awareness of KS among health professionals, and failure by health professionals to p...
