Female Sexual Dysfunction as a Warning Sign of Chronic Disease Development

Prevalence of sexual dysfunction in HTLV-1 patients without spastic paraparesis and the association with psychiatric symptoms

Introduction

The findings of previous studies are inconclusive in terms of psychological abnormalities and sexual function in asymptomatic human lymphotropic virus type 1 (HTLV-1) carriers.

Aim

This study aimed to evaluate the prevalence of sexual dysfunction and its relationship with psychological abnormalities in asymptomatic HTLV-1 carriers.

Materials and Methods

This cross-sectional study was conducted on asymptomatic HTLV-1 patients who were referred to the Neurology Clinic of a tertiary hospital in Mashhad, Iran. Patients with spastic paraparesis, leukemia, and uveitis, and those with an expanded disability status scale (EDSS) score higher than 2 were excluded. Sexual function in male and female subjects was evaluated using the brief male sexual function inventory (BMSFI) and female sexual dysfunction index (FSFI) questionnaires, respectively. The severity of psychological symptoms was evaluated in all patients using the symptom checklist-90-revised (SCL-90-R) questionnaire.

Results

A total of 117 patients (61 males and 56 females) with a mean age of 35.3 ± 6.3 years were evaluated. Overall, 50.9% of males had a high and 39.3% of females had a good sexual function. Both male and female patients with poor sexual function were older and had more children compared to those with good sexual function (P < 0.05). There was no significant difference in the distribution pattern of SCL-90 domains between patients with high and low to moderate sexual function among male patients (P > 0.05). Depression, hostility, interpersonal sensitivity, paranoid ideation, and psychological abnormality were significantly more prevalent in female patients with poor sexual function compared to those with good sexual function (P < 0.05).

Conclusion

The prevalence of psychological abnormalities was high in female with sexual dysfunction and these disorders might have a negative effect on various dimensions of sexual function.

Sexual function in patients with idiopathic inflammatory myopathies: a cross-sectional study

OBJECTIVES

To date, there is almost no information concerning the sexual health of patients with idiopathic inflammatory myopathies (IIM). This cross-sectional study aimed to compare sexual function in patients with IIM to age-/sex-matched healthy controls (HC) and determine the potential impact of clinical features on sexual function.

METHODS

In total, 122 women (61 with IIM, 61 age-matched HC) and 22 men (11 with IIM, 11 age-matched HC) aged 18-80 years completed gender-specific selection of 7 well-established and validated questionnaires assessing sexual health and function (Female Sexual Function Index, Brief Index of Sexual Function for Women, Sexual Function Questionnaire, Sexual Quality of Life Questionnaire-Female, International Index of Erectile Function, Male Sexual Health Questionnaire, Sexual Quality of Life Questionnaire-Male). Results were compared between patients and HC and correlated with selected disease-related features.

RESULTS

The prevalence of sexual dysfunction in IIM was 59% in women (vs 40% in HC), and 64% (vs 9% in HC) in men. Men and women with IIM reported significantly impaired sexual function compared with sex-/age-matched HC. Decreased sexual function was associated with muscle weakness, disability, physical inactivity, fatigue, depression and decreased quality of life.

CONCLUSIONS

Our results suggest that sexual dysfunction is common among IIM patients and more attention should be paid to this aspect of the disease.

Inflammation predicts sexual arousability in healthy women

Background

Though many women report sexual arousal difficulties, the mechanisms driving these difficulties are unclear. Sexual response relies on a host of psychophysiological processes that have bidirectional relationships with inflammation. Additionally, chronic inflammation may impair genital blood flow, which in turn may impact sexual arousal. C-reactive protein (CRP) is an acute-phase marker of inflammation produced in response to cytokine signaling throughout the body, which makes it a useful marker of systemic inflammation.

Aim

The present study examined interactions between inflammation and women's sexual arousal.

Methods

CRP, self-reported frequency of partnered sexual activity, and subjective and vaginal arousal were assessed in 91 healthy, pre-menopausal women. Data were collected during a single laboratory session.

Main outcome measures

Subjective sexual arousal and vaginal pulse amplitude (a measure of vaginal arousal) were the main outcome measures.

Results

Change in subjective sexual arousal in response to a sexual film was unaffected by baseline CRP and sexual frequency. However, there were significant interactions between inflammation and sexual frequency in predicting vaginal arousal during the sexual film. Among women reporting more frequent sexual activity, higher CRP predicted lower magnitude arousal response and longer time to maximum vaginal arousal. Among women reporting less frequent sex, higher CRP predicted shorter time to maximum arousal and greater magnitude of arousal response. Controlling for cortisol strengthened the effects seen for time to maximum vaginal arousal but weakened those observed for percent change.

Conclusions

Among healthy young women, higher CRP may be associated with vaginal arousal, but not subjective sexual arousal. Specifically, our results suggest that higher baseline CRP is associated with lower genital sexual arousal for women who have sex frequently, which is consistent with clinical evidence that elevated inflammation can be detrimental to sexual function.

•

Among healthy young women, higher CRP may be associated with vaginal sexual arousal, but not subjective sexual arousal.

•

Frequency of sexual activity interacts with CRP levels to contribute to vaginal arousal in healthy women.

•

Higher CRP predicted lower genital sexual arousal in women who engage in sexual activity more than once a week.

•

However, higher CRP predicted greater genital sexual arousal in women who engage in sexual activity less than once a week.
