Relationship of Blood Pressure and Erectile Dysfunction in Men Without Previously Diagnosed Hypertension

Factors Associated with Erectile Dysfunction Among Older Gay Men

Erectile dysfunction (ED) is a common issue that aging men encounter, but whether internalized gay ageism (i.e., the internalization of ageist messages within the context of aging as a gay man) is related to ED among older gay men is unknown. A cross-sectional web-based survey explored the relationship between internalized gay ageism, health-related and social factors, and ED among older gay men who resided in the Midwest United States (N = 181). Internalized gay ageism was not significantly associated with ED. However, hierarchical regression analysis found that age (β = .224, t = 2.70, p = .008) and overall health (β = -.247, t = -3.05, p = .003) were significantly associated with ED among older gay men, suggesting that older gay men share similar risk factors for ED as the general male population. Future research should continue to explore other factors that are unique to gay men that may be associated with ED.

Global prevalence of sexual dysfunction in cardiovascular patients: a systematic review and meta-analysis

BACKGROUND

Sexual dysfunction poses a significant challenge for patients with cardiac conditions. Concerning the prevalence of sexual disorders in cardiovascular patients, several seminal studies conducted in various regions of the world have provided diverse facts and figures pertaining to sexual dysfunction among cardiovascular patients. Therefore, the present study aimed to analyze, summarize, and integrate the findings of seminal studies on the effect of underlying factors and estimate the global rate of sexual disorders in cardiovascular patients.

METHODS

The present systematic review and meta-analysis included studies conducted in 2003-2023. To find the relevant published academic papers, SID, MagIran, PubMed, Scopus, Web of Science (WOS), and Google Scholar databases were searched for keywords using MeSH/Emtree until January 14, 2023. The GRADEpro software was used to evaluate the quality of evidence. The heterogeneity of studies was checked using the I2 index.

RESULTS

An initial number of 2122 studies were found in the first search. Following a precise screening process based on predefined inclusion criteria, a total of 17 studies were deemed suitable for inclusion in the meta-analysis. The global prevalence of sexual disorders in cardiovascular patients was estimated at 62.6% (95% CI: 49.8-73.8%). As the results of the meta-regression showed that as the sample size increased, there was a significant decrease in the overall prevalence of sexual disorders among cardiovascular patients. Additionally, as the study years progressed, both age and JBI score exhibited an upward trend.

CONCLUSION

The present findings showed a high prevalence of sexual disorders among cardiovascular patients. Therefore, it is recommended that experts and health policymakers enhance their focus on effectively preventing and controlling these disorders. Besides the evidence achieved very low certainty, it is important for the treatment team to prioritize the sexual relations of cardiovascular patients and focus on improving their sexual function. This should be seen as an essential aspect of their overall recovery process.

The relationship between social support and erectile dysfunction in middle-aged and older males

Background

Erectile dysfunction (ED) is a prevalent condition that affects middle-aged and older men, impacting their sexual health and overall wellbeing. We aimed to investigate the relationship between social support and ED among this specific population.

Methods

Data were collected from the National Health and Nutrition Examination Survey. Social support was assessed through various dimensions, including emotional support, material support, and network support. Multivariate logistic regression was performed to examine the association between social support and ED, and a propensity-score-matched (PSM) analysis was further conducted.

Results

Among 1938 middle-aged and older males in the United States, 49.9% had a history of ED. ED was more prevalent in older individuals and those with comorbidities such as hypertension, prostate disease, higher serum creatinine level, and mental problems. Males with lower social support scores had a higher weighted rate of ED (P < 0.001). After adjusting for multiple variables in logistic regression analysis, a higher social support score was associated with a 19% lower likelihood of ED (weighted odds ratio [OR] 0.81, 95% confidence interval [CI] 0.66-0.98, P = 0.032). The association remained consistent after propensity score matching (OR 0.80, 95% CI 0.66-0.98, P = 0.028).

Conclusion

Social support appears to be associated with a reduced risk of ED in middle-aged and older men. Further research is needed to better understand this relationship and explore interventions that enhance social support, potentially leading to improved sexual health outcomes.

Relationship Between Hypertension, Antihypertensive Drugs and Sexual Dysfunction in Men and Women: A Literature Review

Sexual dysfunction pertains to any issue that hinders an individual from attaining sexual contentment. This health issue can have a significant impact on the quality of life and psychological health of affected individuals. Sexual dysfunction can generate stress, anxiety, depression, and low self-esteem, which can lead to a reduction in overall life satisfaction and the quality of interpersonal relationships. Sexual dysfunction can manifest as erectile dysfunction in men or lack of sexual desire in women. Although both sexes can experience sexual problems, there are some significant differences in the manifestation of sexual dysfunction between men and women. In men, sexual dysfunction is usually physical and associated with problems such as erectile dysfunction, while in women, sexual dysfunction is usually related to psychological factors. Additionally, there was an association between hypertension and sexual dysfunction in both the sexes. In men, hypertension can cause erection problems, whereas in women, it can cause vaginal dryness and a decrease in sexual desire. Furthermore, antihypertensive drugs can negatively impact sexual function, which can decrease adherence to drug treatment. However, nebivolol, an antihypertensive drug, has beneficial effects on erectile dysfunction in men. This is believed to be because nebivolol improves blood flow to the penis by producing nitric oxide, which can help improve erections.

Erectile dysfunction and diabetes: A melting pot of circumstances and treatments

Diabetes mellitus (DM), a chronic metabolic disease characterised by elevated levels of blood glucose, is among the most common chronic diseases. The incidence and prevalence of DM have been increasing over the years. The complications of DM represent a serious health problem. The long-term complications include macroangiopathy, microangiopathy and neuropathy as well as sexual dysfunction (SD) in both men and women. Erectile dysfunction (ED) has been considered the most important SD in men with DM. The prevalence of ED is approximately 3.5-fold higher in men with DM than in those without DM. Common risk factors for the development of DM and its complications include sedentary lifestyle, overweight/obesity and increased caloric consumption. Although lifestyle changes may help improve sexual function, specific treatments are often needed. This study aims to review the definition and prevalence of ED in DM, the impact of DM complications and DM treatment on ED and, finally, the current and emerging therapies for ED in patients with DM.

Effect of Intensive vs Standard Blood Pressure Treatment Upon Erectile Function in Hypertensive Men: Findings From the Systolic Blood Pressure Intervention Trial

INTRODUCTION

The effect of intensive blood pressure control upon erectile function in men with hypertension, but without diabetes, is largely unknown.

AIM

To examine the effects of intensive systolic blood pressure (SBP) lowering on erectile function in a multiethnic clinical trial of men with hypertension.

METHODS

We performed subgroup analyses from the Systolic Blood Pressure Intervention Trial ([SPRINT]; ClinicalTrials.gov: NCT120602, in a sample of 1255 men aged 50 years or older with hypertension and increased cardiovascular disease risk. Participants were randomly assigned to an intensive treatment group (SBP goal of <120 mmHg) or a standard treatment group (SBP goal of <140 mmHg).

MAIN OUTCOME MEASURE

The main outcome measure was change in erectile function from baseline, using the 5-item International Index of Erectile Function (IIEF-5) total score, and erectile dysfunction ([ED]; defined as IIEF-5 score ≤21) after a median follow-up of 3 years.

RESULTS

At baseline, roughly two-thirds (66.1%) of the sample had self-reported ED. At 48 months after randomization, we determined that the effects of more intensive blood pressure lowering were significantly moderated by race-ethnicity (p for interaction = 0.0016), prompting separate analyses stratified by race-ethnicity. In non-Hispanic whites, participants in the intensive treatment group reported slightly, but significantly better change in the IIEF-5 score than those in the standard treatment group (mean difference = 0.67; 95% CI = 0.03, 1.32; P = 0.041). In non-Hispanic blacks, participants in the intensive group reported slightly worse change in the IIEF-5 score than those in the standard group (mean difference = -1.17; 95% CI = -1.92, -0.41; P = 0.0025). However, in non-Hispanic whites and non-Hispanic blacks, further adjustment for the baseline IIEF-5 score resulted in nonsignificant differences (P > 0.05) according to the treatment group. In Hispanic/other participants, there were no significant differences in change in the IIEF-5 score between the two treatment groups (P = 0.40). In a subgroup of 280 participants who did not report ED at baseline, the incidence of ED did not differ in the two treatment groups (P = 0.53) and was without interaction by race-ethnicity.

CLINICAL IMPLICATIONS

The effect of intensive treatment of blood pressure on erectile function was very small overall and likely not of great clinical magnitude.

STRENGTH & LIMITATIONS

Although this study included a validated measure of erectile function, testosterone, other androgen, and estrogen levels were not assessed.

CONCLUSION

In a sample of male patients at high risk for cardiovascular events but without diabetes, targeting a SBP of less than 120 mm Hg, as compared with less than 140 mm Hg, resulted in statistically significant effects on erectile function that differed in accordance with race-ethnicity, although the clinical importance of the differences may be of small magnitude.

Penile Doppler ultrasonography and elastography evaluation in patients with erectile dysfunction

Purpose

To evaluate the relationship between erection grade, erectile function score, Doppler ultrasonography (US) indexes, and elasticity score (ES) according to Doppler US diagnosis in patients with erectile dysfunction (ED).

Material and methods

Real-time strain type penile elastography was performed during penile Doppler US examination for 88 patients with ED. The diagnosis according to Doppler US was determined. Erection score according to the Erection Hardness Grading Scale was evaluated. A scoring for erectile function was performed with the International Index of Erectile Function (IIEF-5), and the Sexual Health Inventory for Men (SHIM) was defined. The relationships, according to Doppler diagnosis, of ES, IIEF-5 score, SHIM scale, and erection score were evaluated.

Results

Among the patients, 50 (57%) had abnormal penile Doppler US findings. According to Doppler US findings, patients were classified as normal (n = 38), borderline for arterial insufficiency (n = 4), arterial insufficiency (n = 5), and venous insufficiency (n = 41). The lowest erection hardness grades and IIEF-5 scores were detected in patients with arterial failure. When compared to the normal group, in terms of ES, the arterial failure borderline group and venous failure group had lower scores, and the arterial failure group had a higher score. However, the only significant difference was obtained in the left cavernous body of the venous failure group.

Conclusions

Sonoelastography seems to add additional value for determination of stiffness of the penile cavernous body in routine evaluation of ED.

Cardiorenal Determinants of Erectile Dysfunction in Primary Prevention: A Cross-Sectional Study

OBJECTIVE

The aim of this study was to investigate the association between the severity of erectile dysfunction (ED), cardiovascular risk, and target organ damage (heart, renal, vascular) in men free of cardiovascular diseases (CVD).

SUBJECTS AND METHODS

ED was assessed using the International Index of Erectile Function (IIEF-5). The study included 182 men: 100 with ED (IIEF mean score ≤21) and 82 without ED (IIEF mean score >21). Ultrasound was used to evaluate carotid plaques and left ventricular mass, geometry, and diastolic function. Cardiovascular anamnesis, CVD risk factors, and anthropometric and biochemical parameters were obtained. The European Society of Cardiology-Systematic Coronary Risk Evaluation Score (ESC-SCORE) was used to calculate total patient cardiovascular risk. Continuous variables between groups were compared using the Student t test and Mann-Whitney U test, while categorical data were compared using the χ2 test. Multiple linear regression was used to test the association between the severity of ED and presence of target organ damage.

RESULTS

The following parameters were significantly higher in the ED group compared to the controls: family history of coronary heart disease (43.7 vs. 26.7%, p = 0.047), ESC-SCORE (2.27 ± 1.79 vs. 1.61 ± 1.13, p = 0.012), and waist circumference (109.28 ± 10.82 vs. 106.17 ± 10.07, p = 0.047). Impaired renal function (p = 0.081), albuminuria (p = 0.545), vascular damage (p = 0.602), and diastolic function (p = 0.724) were similar in both groups. However, left ventricular hypertrophy (LVH; odds ratio 2.231, 95% CI 1.069-4.655, p = 0.22) was more frequent in the ED group (29.9 vs. 16.0%). The multiple linear regression analysis revealed that LVH (β = 1.761, p = 0.002) and impaired renal function assessed using the estimated glomerular filtration rate (<60 mL/min/1.73 m2; β = 6.207, p = 0.0001) were the independent risk factors for severity of ED.

CONCLUSION

This study showed that LVH and impaired renal function are associated with ED severity.
