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.</...

Objectives: Recommending general dynamic penile color doppler ultrasound (D-PCDU) screening in patients with erectile dysfunction (ED) has been questioned due to an inadequate cost-benefit ratio. The aim of the present study is to asses the validity of different risk scores in the identification of patients being screened for arteriogenic ED at D-PCDU.Design and methods: A consecutive series of 738 (mean age 53.6±9.2 years) patients with ED was stud...

Objectives: The aim of present study is to determine psychobiological characteristics of sexual dysfunction (SD) associated with metabolic syndrome (MS; as defined by National Cholesterol Education Program’s Adult Treatment Panel III, NCEP-ATP-III criteria) in a consecutive series of 803 male out-patients.Methods: Several hormonal, biochemical and instrumental (penile doppler ultrasound, PDU) parameters were studied, along with psycho...

Scrotal color-doppler ultrasonography (sCDUS) and transrectal ultrasonography (trCDUS) provide crucial information about the clinical status of testes and male accessory glands. However, the US evaluation of the infertile male is still often considered as a second level diagnostic tool. To analyze the role of ultrasound in male infertility, in order to predict hypothalamic-pituitary-testicular axis function, 1120 records from infertile men were retrospectively evaluated (from ...

Introduction: Although in females of infertile couples abnormal PRL has a definitive role in the medical flow-chart, its role in males is less clear. Animal models suggest that PRL does not play a major role in male reproduction, although its trophic action on male accessory glands was often observed. Studies in humans are scanty. We systematically evaluated possible clinical and ultrasound correlates of PRL in males of infertile couples.Methods: Out of ...

Introduction: ‘Prostatitis-like symptoms’ (PLS) are a cluster of bothersome conditions defined as ‘perineal and/or ejaculatory pain or discomfort and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) pain subdomain score ≥4’ (Nickel’s criteria). PLS may originate from the prostate or from other portions of the male genital tract. Although PLS could be associated with ‘prostatitis’, they should not be confused. T...

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...

Introduction: Metabolic syndrome (MetS) is a diagnostic category which identifies subjects at high risk for diabetes and cardiovascular diseases, erectile dysfunction (ED) and male hypogonadism. However, MetS impact on male infertility has been poorly studied. We systematically evaluated possible associations between MetS and clinical characteristics in men with couple infertility.Methods: Out of 367 consecutive subjects, 351 men without genetic abnormal...

The role of psychological symptoms in recognizing late-onset hypogonadism (LOH) is still controversial. The aim of the study is to evaluate the association between LOH and specific psychological symptoms and to verify whether investigating intra-psychic domain improves the accuracy of a validated case-history tool (ANDROTEST) in detecting LOH. A consecutive series of 1009 subjects (mean age 49.23±13.34) consulting for sexual dysfunction was studied. Intra-psychic symptoms...

Introduction: Few randomised clinical studies have evaluated the impact of diet and physical activity on testosterone levels in obese men with conflicting results. Conversely, studies on bariatric surgery in men generally showed an increase in testosterone levels. The aim of the present study is to perform a systematic review and meta-analysis of available trials on the effect of body weight loss on sex hormones levels.Methods: An extensive Medline searc...
