Erectile dysfunction in stroke patients: a multifactorial problem with important psychosocial consequences

Sexual disorders post-stroke: Description of a cohort of patients followed in rehabilitation

INTRODUCTION

The impairments resulting from a stroke can be multiple, including urinary and/or sexual dysfunctions. This acquired brain injury disrupts neurological control of sexual responses.

MAIN OBJECTIVE

to describe sexual disorders, after a first episode of stroke, in a population followed in a physical medicine and rehabilitation (PMR) center.

SECONDARY OBJECTIVES

to gather patients' expectations and PMR physicians' opinions on this subject.

METHOD

Observational, retrospective study in two PRM centers. Post-stroke sexuality was assessed using two validated questionnaires [for men: International Index of Erectile Function 15 (IIEF15) and for women: Female Sexual function Index (FSFI)]. Patients were asked 3 questions to approximate their expectations, and PRM physicians were asked 2 questions for their opinions.

RESULTS

Twenty-four subjects included (17 men/7 women). Thirteen had no post-stroke sexuality. Erectile function was analysable in 4 subjects, 3 of whom had moderate to severe erectile dysfunction. In women, female sexual dysfunction concerned 6/7 women, including lubrication. Ninety-six percent of subjects had never discussed sexuality with their PRM physician. Only 33% would have liked information on this subject. Our PRM physicians rarely discuss post-stroke sexual disability.

CONCLUSION

Post-stroke sexual disorders occur in both sexes. All areas of sexuality may be affected. A large-scale, prospective, controlled, multicenter study is needed to establish stroke as the direct neurological cause of sexual impairment.

Acupuncture for erectile dysfunction in post-stroke patients: Study Protocol Clinical Trial (SPIRIT Compliant)

INTRODUCTION

Erectile dysfunction refers to the continued inability of the penis to reach and maintain sufficient erections to achieve a satisfactory sex life and last at least 6 months. As part of traditional Chinese medicine, acupuncture has been widely used in clinical practice. In order to evaluate, the exact effect of acupuncture on the clinical efficacy of patients with Post-stroke Erectile dysfunction (PSED), this experiment uses randomized controlled experiments.

METHODS/DESIGN

This pragmatic randomized controlled trial will recruit 103 patients who are diagnosed with PSED. Simple randomization to conventional treatment with a 1:1 allocation ratio will be used. Ten 30-min acupuncture sessions will be provided to patients assigned to the Intervention group. All participants will continue to receive conventional treatment. The selection of outcomes will be evaluated by International Erectile Function Index-5 (IIEF-5) score at week 8.

DISCUSSION

This trial may provide evidence regarding the clinical effectiveness, safety, and cost-effectiveness of acupuncture for patients with PSED.

Positive Correlation between Left Hemisphere Lesion and Erectile Dysfunction in Post-Stroke Patients

BACKGROUND:

Stroke is a serious health condition and the leading cause of disability, including erectile dysfunction (ED). The mechanisms and factors that predict ED in stroke are not fully elucidated. Several studies have shown a relationship between the location of the lesion in stroke with the onset of ED. The left hemispheric lesion was believed to disrupt the parasympathetic nervous system which is responsible for the regulation of erection. Stroke attack in this region therefore can be the underlying reason for ED. However, there are still contradictory findings in this area, and very few studies attempted to look at this problem, particularly among Asian male.

AIM:

We would like to evaluate the association between left hemisphere lesion after ischemic stroke and the subsequent risk of developing ED.

METHODS:

The study was conducted in the neurology polyclinic of Sanglah and Wangaya Hospital from February to August 2013. Subjects are all post-stroke patients who visited the neurology polyclinic of Sanglah and Wangaya Hospital that met inclusion and exclusion criteria.

RESULTS:

There is a significant positive correlation (p < 0.05) between left hemisphere lesions and ED in stroke patients with a correlation coefficient (r) = 0.361 which means weak correlation and p = 0.032.

CONCLUSION:

Left hemisphere lesions positively correlated with ED in stroke patients. Further longitudinal research is needed to see whether left hemisphere lesion in post-stroke patients is a risk factor for ED.

The relevance of sexual responsiveness to sexual function in male stroke patients

INTRODUCTION

Stroke may have negative consequences for the patients' quality of life, including sexual function. Whereas physical impairment will influence sexual positions and movement during sex, depression and medication may reduce sexual desire. So far, data on sexual dysfunction after stroke are scant. Although some support for physical as well as psychological explanations has been shown, further research to find the remedies for those patients with sexual problems after stroke is needed. The focus of the present study is on the identification of relevant psychological factors.

AIM

The aim of this study was to study the impact of anxiety, depression, and sexual responsiveness on sexual function in male stroke patients.

METHODS

Nineteen male stroke patients completed a number of self-report measures to assess psychological and sexual factors.

MAIN OUTCOME MEASURES

Sexual function based on the International Index of Erectile Function, anxiety and depression based on the Symptom Checklist-90, and sexual responsiveness based on the Sexual Inhibition/Sexual Excitation Scale, including propensities for sexual excitation and sexual inhibition as a result of both performance failure and performance consequences, were assessed.

RESULTS

Sexual excitation was positively related to sexual desire, whereas inhibition because of the threat of performance failure was negatively related to orgasmic function and sexual desire (P < 0.01). Patients with high levels of inhibition because of threat of performance failure were more likely to report low scores on overall sexual function than those with low levels.

CONCLUSIONS

Although the statistical power is rather low, the results show the relevance of sexual responsiveness to sexual function in male stroke patients. The present study can be considered as a first step toward building a theoretical framework of relevant psychological and physical factors, which is needed to develop adequate interventions for those patients with sexual problems after stroke.
