Erectile dysfunction is associated with low total serum testosterone levels and impaired flow-mediated vasodilation in intermediate risk men accordin…
2015
Background: The role erectile dysfunction (ED) coupled with low testosterone levels as early markers of atherosclerosis is not well understood. Objectives: To analyze the relationship between serum testosterone levels with both ED and brachial artery flow-mediated vasodilation (FMD), in a primary prevention sample of men. Methods: We enrolled 802 asymptomatic, intermediate CV risk patients, according to the Framingham Risk Score, aged 40e80 years, who underwent the ultrasound examination of FMD, the evaluation of ED and the assessment of total serum testosterone levels. Results: Testosterone levels correlated both with FMD (r ¼ 0.85; p < 0.0001) and IIEF-5 score (rs ¼ 0.65; p < 0.0001…
Hormonal changes of intimate partner violence perpetrators in response to brief social contact with women
2022
This study investigated whether men with a history of real-life aggressive, dominant behavior show increases in testosterone and cortisol levels after brief social contact with women. Furthermore, we tested the prediction that such changes in hormones would be larger than those observed previously in young male students. Sixty-seven male participants convicted of intimate partner violence (IPV) either had brief social contact with a female confederate (experimental condition) or a male confederate (control condition). We also performed meta-analyses to investigate whether IPV perpetrators' hormonal responses were larger than the typical responses of young male students in prior studies. All…
Low levels of testosterone levels increase the risk of major cardiovascular events in a follow-up to 5 years
2014
Materials and Methods. We evaluated a series of 802 patients with intermediate cardiovascular risk according to the Framingham Risk Score (FRS). The endothelial function through flow-mediated vasodilatation (FMD), the erectile function (EF), and the total serum testosterone levels were assessed. Patients were followed for up to 5 years and the prevalence and predictors of MACEs were evaluated. Results. The levels of serum testosterone are related with both endothelial function (FMD) (t=9,4080, 95% CI= 0,9318 to 1,4234, p<0,0001) and erectile function (FMD) (t=8,9584, 95% CI= 0,7642 to 1,1932, p<0,0001). Analysis of variance (ANOVA) of serum testosterone levels are related with the MACEs (F-…
Influence of Oral Contraceptive Use on Adaptations to Resistance Training
2019
Introduction: The majority of young women use oral contraceptives (OCs). Use of OCs has been associated with lower myofibrillar protein and tendon collagen synthesis rates, but it is unknown whether OCs will limit the adaptive response of myotendinous tissue to resistance training. Design and Methods: Fourteen healthy untrained young regular OC users (24 +/- 1 years, fat% 32 +/- 1, 35 +/- 2 ml.min(-1).kg(-1)) and 14 NOC users (non-OC, controls) (24 +/- 1 years, fat% 32 +/- 2, 34 +/- 2 ml.min(-1).kg(-1)) performed a 10-week supervised lower extremity progressive resistance training program. Before and after the intervention biopsies from the vastus lateralis muscle and the patellar tendon we…
The relationship between endothlial ABD erectile dysfunction, levels of testosterone and cardiovascular events in the follow-up
2016
Background: Clinical and experimental evidence suggest that testosterone levels play a role in cardiac and vascular pathology. A long history of observational studies investigating serum testosterone level and cardiovascular risks, specifically mortality, reveals important associations between low testosterone and mortality, while higher serum testosterone level appear to be predictive in the majority of studies. On the other hand, it is well documented and accepted that endothelial dysfunction is expression of preclinical atherosclerosis and it is associated with an increased amount of CV events in the follow-up. Erectile dysfunction is also an early manifestation of arteriosclerosis assoc…
Testosterone levels are directly related with erectile function and endothelial function in men with intermediate risk according to the Framingham sc…

Background. The value of testosterone levels and erectile dysfunction (ED) as early markers of atherosclerosis is not well understood. Objectives. To analyze the relationship between plasma testosterone levels in men with both endothelial function (F) and ED. Methods. We enrolled 802 asymptomatic, intermediate cardiovascular risk patients, according to the Framingham Risk Score, aged 40 to 80 years, who underwent the study of EF, evaluation of ED and dosage of plasma testosterone. Results. At linear regression, EF (t=9.40; 95% CI from 0.9318 to 1.4234; p<0.0001) and erectile function (t=8.96; 95% CI from 0.7642 to 1.1932; p<0.0001) statistically increased with increasing levels of testoster…
