Excess of adiposity is a risk factor for coronary artery disease, but it remains unclear if the distribution of fat is an effect modifier or if the risk is mediate by hypertension, diabetes and dyslipidemia. We investigated the association of central in addition to general obesity with coronary artery disease (CAD). A case-control study was conducted in 376 patients, aged 40 years or more, with chronic coronary disease, undergoing elective coronary angiography.

Methods: A total of 213 men were analyzed. Fasting blood samples were drawn for the determination of the lipid profile as well as of plasmatic glucose and serum levels of albumin, TT, aFT, and sex hormone-binding globulin (SHBG).
Purpose: To evaluate the influence of age on serum levels of total testosterone (TT), bioavailable testosterone (BT), free testosterone (FT), and sex-hormone binding globulin (SHBG), considering the presence of fasting blood glucose levels and body mass index (BMI) in a selected male population.
Methods: A total of 428 men were analyzed. Anthropometry was taken from all, considering BMI as general obesity indicative variable.
Introduction: The association between erectile dysfunction (ED) and coronary artery disease (CAD) has been described in various settings, but it is unclear if there is an independent interaction with age.
Aim: To investigate the interaction of age in the association between ED and CAD.
Methods: This case-control study was conducted among 242 patients referred for elective coronary angiography.
Introduction: Although Peyronie's Disease (PD) was first described over 250 years ago, its precise etiology remains obscure.
Aim: Analyze a variety of potential associated factors with PD, including erectile dysfunction.
Materials And Methods: This cross-sectional study included 83 consecutive men with PD and 252 age-matched controls.
Aim: To investigate the relationship between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), while considering multiple risk factors for ED, including an anthropometric evaluation of central obesity.
Methods: A cross-sectional study was carried out with 192 consecutive male subjects (>or=40 years old). Conditions clearly associated with ED, other than obesity and age, were considered exclusion criteria.
Purpose: We determined whether the ratio of serum testosterone to prostate specific antigen might provide diagnostic value regarding the risk of prostate cancer in a population of hypogonadal men undergoing prostate biopsy.
Materials And Methods: The study population consisted of 184 consecutive men with symptomatic hypogonadism and prostate specific antigen 4.0 ng/ml or less who underwent prostate biopsy before the anticipated initiation of testosterone therapy.
Purpose: There is a growing body of evidence in the literature correlating erectile dysfunction to obesity. We investigated the correlation of different anthropometric indexes of central obesity to erectile dysfunction.
Materials And Methods: A cross-sectional study was performed including 256 consecutive men 40 years old or older.
Objective: To evaluate the association between the levels of glycosylated haemoglobin (HbA1c) and the severity of erectile dysfunction (ED) in men with diabetes mellitus (DM).
Patients And Methods: This cross-sectional study included sexually active men with a diagnosis of DM attending a urological medical centre from January 2000 to December 2001. The 115 men with ED (95%) completed the International Index of Erectile Function questionnaire, and fasting serum glucose and HbA1c serum levels were measured.
