Sexual orientation matters in sexual medicine

Sexual Dysfunction Among Men Who Have Sex with Men: a Review Article

PURPOSE OF REVIEW

The goal of this review article is to evaluate sexual dysfunction among men who have sex with men (MSM).

RECENT FINDINGS

Men who have sex with men are commonly affected by sexual dysfunction. Often sexual dysfunction in MSM will significantly impact their psychological well-being perhaps even more than their heterosexual counterparts. Despite the frequency and high impact of sexual dysfunction in MSM, access to appropriate care may be limited. It is important for urologists, especially sexual medicine clinicians, to be aware of and comfortable with differences in sexual practices of MSM. Penile pathology in this patient population will negatively affect their quality of life and well-being. Therefore, it is important to properly assess and treat these patients.

What do physicians know about homosexuality? Translation and adaptation of Knowledge about Homosexuality Questionnaire

Objective:

To adapt the Knowledge about Homosexuality Questionnaire to Brazilian Portuguese, and to assess knowledge of heterosexual physicians on homosexuality.

Methods:

The following steps for cultural adaptation were made: translation by two independent evaluators, translation synthesis, and evaluation of semantic properties by the target population, followed by the development of a pilot study and administration of the instrument to 224 heterosexual physicians working in the Brazilian Federal District.

Results:

The mean number of correct answers in the questionnaire was 11.8 (SD=2.81) out of 18 items, i.e., 65.5%. Catholic and evangelical physicians gave a significant lower number of correct answers compared with those who believed in other religions or who did not believe in any religion (p=0.009), and 40% of sample did not know that homosexuality is not considered a disease.

Conclusion:

This study adapted the American instrument entitled Knowledge about Homosexuality Questionnaire and provided evidence for its validation in Brazil, revealing physicians' lack of knowledge about several aspects related to homosexuality. The findings of this study may help in guiding improvements in medical training and practice.

A pilot study of HIV/STI risk among men having sex with men using erectile dysfunction medications: challenges and opportunities for sexual medicine physicians

INTRODUCTION

A growing literature suggests relationships between erectile dysfunction medications (EDM) and riskier sexual behavior among men who have sex with men (MSM). Questions remain concerning EDM use and related HIV/sexually transmitted infections (STI) risk among older MSM, particularly those 40 years and over, for whom EDM may be medically warranted.

AIM

This exploratory pilot study explores the relationship between EDM and risky sexual behavior in a convenience sample of MSM using EDM and attending historic sex-on-premises venues.

METHODS

We examined anonymous surveys from 139 MSM. Bivariate relationships were examined. We then fit a multiple logistic regression model to determine predictors of engaging in unprotected anal intercourse (UAI) at last EDM, using variables identified as being significantly related to UAI in the bivariate analyses. Potential predictors entered the model in a stepwise fashion.

MAIN OUTCOME MEASURES

The primary outcome measure was engaging in UAI at last EDM use.

RESULTS

MSM participating in the study ranged from 27 to 77 years and averaged 52.0 years (standard deviation = 10.73 years). These participants were primarily older MSM; fewer were younger MSM (12.12%), under age 40. Participants reporting UAI at last EDM use (N = 41) were significantly younger (P < 0.01). Men visiting bars within the last 6 months reported less UAI (P < 0.01). Both variables were independent predictors of UAI in the logistic regression model (P < 0.01).

CONCLUSIONS

Similar to reports from younger MSM, our findings suggest older MSM using EDM and reporting UAI are also recreational drug users. We include recommendations for urologists and other sexual medicine physicians treating MSM who may be at elevated risk for HIV/STI infection because of joint EDM and club drug use.

An Internet survey of demographic and health factors associated with risk of sexual dysfunction in women who have sex with women

INTRODUCTION

There has been scant attention to predictors of sexual dysfunction in women who have sex with women (WSW).

AIM

To investigate the associations of high risk for sexual dysfunction in an Internet cohort of WSW.

MAIN OUTCOME MEASURE

A modified version of the Female Sexual Function Index (FSFI) was used to quantify each subject's sexual function.

METHODS

Women who have sex with women were invited to participate in an Internet-based survey by invitations posted on e-mail listservs and on social media sites catering to WSW. Ethnodemographic, health status, and sexual/relationship data were collected.

RESULTS

The study was completed by 2,433 adult women. Of these, 1,566 participants had complete data on the FSFI and comprised the study cohort; 388 (24.8%) met the FSFI criteria for high risk of female sexual dysfunction (HRFSD). On multivariable analysis, the following variables were found to be independently associated with the HRFSD; moderate or severe subjective bother regarding sexual function (OR 4.8, 95% CI 3.0-7.9 and 13.7, 95% CI 7.5-25.1, respectively), overactive bladder (OAB) (OR 2.1, 95% CI 1.0-4.5), having a nonfemale or no partner (OR 2.3, 95% CI 1.1-4.7 and 3.2, 95% CI 2.0-5.2, respectively). A history of pregnancy was associated with lower odds of HRFSD (OR 0.567, 95% CI 0.37-0.87). Mean FSFI domain scores for all domains except desire were negatively impacted by partner factors and OAB.

CONCLUSIONS

A single-item question on sexual bother is strongly predictive of potentially distressing sexual problems in the WSW. A number of health and social factors are associated with risk of sexual problems in the WSW. Assessment of sexual well-being in the WSW is a priority for practicing healthcare providers.

Erectile dysfunction and premature ejaculation in men who have sex with men

INTRODUCTION

Quantitative research into sexual function and dysfunction in men who have sex with men (MSM) has been sparse due in large part to a lack of validated, quantitative instruments for the assessment of sexuality in this population.

AIM

To assess prevalence and associations of erectile problems and premature ejaculation in MSM.

METHODS

MSM were invited to complete an online survey of sexual function. Ethnodemographic, sexuality, and health-related factors were assessed.

MAIN OUTCOME MEASURE

Participants completed a version of the International Index of Erectile Function modified for use in MSM (IIEF-MSM) and the Premature Ejaculation Diagnostic Tool (PEDT). Total score on the erectile function (EF) domain of the IIEF-EF (IIEF-MSM-EF) was used to stratify erectile dysfunction (ED) severity (25-30 = no ED, 16-24 mild or mild moderate ED, 11-15 moderate ED, and ≤10 severe ED). PEDT scores were used to stratify risk of premature ejaculation (PE, diagnosed as PEDT score ≥9).

RESULTS

Nearly 80% of the study cohort of 2,640 men resided in North America. The prevalence of ED was higher in older men whereas the prevalence of PE was relatively constant across age groups. Multivariate logistic regression revealed that increasing age, HIV seropositivity, prior use of erectogenic therapy, lower urinary tract symptoms (LUTS), and lack of a stable sexual partner were associated with greater odds of ED. A separate multivariate analysis revealed that younger age, LUTS, and lower number of lifetime sexual partners were associated with greater odds of PE.

CONCLUSIONS

Risk factors for sexual problems in MSM are similar to what has been observed in quantitative studies of non-MSM males. Urinary symptoms are associated with poorer sexual function in MSM.

Sexual dysfunction, HIV, and AIDS in men who have sex with men

HIV infection is associated with sexual dysfunction. Using validated instruments, we investigated the relationship between HIV/AIDS and sexual function in a contemporary cohort of men who have sex with men (MSM). An anonymous Internet-based survey was disseminated to MSM via organizations and social networking sites that cater to this population. Information on ethnodemographic variables, health status (including HIV status, disease stage, and other health conditions), and sexual behavior was collected. Men were categorized as HIV-negative, HIV-positive/AIDS-negative, or HIV-positive /AIDS-positive. A modified validated version of the International Index of Erectile Function (IIEF) for use in MSM and the Premature Ejaculation Diagnostic Tool (PEDT) were used to stratify risk of sexual dysfunction. The study cohort included 1361 men (236 of whom were HIV-positive) who provided complete data on HIV status, IIEF, and PEDT. There was a significant trend toward greater prevalence of erectile dysfunction (ED) in men with progressive HIV infection 40-59 years of age relative to age matched HIV-negative men (p=0.02). In a logistic regression model controlling for other variables, HIV infection without AIDS was not associated with greater odds of ED; however, HIV infection with AIDS was associated with greater odds of ED (p=0.006). In a separate logistic regression model, HIV infection with or without AIDS was not significantly associated with greater odds of premature ejaculation (p>0.05). Use of phosphodiesterase 5 (PDE5) inhibitor drugs was much more common in HIV-infected men. HIV infection is a risk factor for poorer sexual function primarily due to higher risk of erectile dysfunction in men with AIDS.

The impact of sexual orientation on sexuality and sexual practices in North American medical students

INTRODUCTION

There has been limited investigation of the sexuality and sexual dysfunction in non-heterosexual subjects by the sexual medicine community. Additional research in these populations is needed.

AIMS

To investigate and compare sexuality and sexual function in students of varying sexual orientations.

METHODS

An internet-based survey on sexuality was administered to medical students in North American between the months of February and July of 2008.

MAIN OUTCOME MEASURES

All subjects provided information on their ethnodemographic characteristics, sexual orientation, and sexual history. Subjects also completed a series of widely-utilized instruments for the assessment of human sexuality (International Index of Erectile Function [IIEF], Female Sexual Function Index [FSFI], Premature Ejaculation Diagnostic Tool [PEDT], Index of Sex Life [ISL]).

RESULTS

There were 2,276 completed responses to the question on sexual orientation. 13.2% of male respondents and 4.7% of female respondents reported a homosexual orientation; 2.5% of male and 5.7% of female respondents reported a bisexual orientation. Many heterosexual males and females reported same-sex sexual experiences (4% and 10%, respectively). Opposite-sex experiences were very common in the male and female homosexual population (37% and 44%, respectively). The prevalence of premature ejaculation (PEDT > 8) was similar among heterosexual and homosexual men (16% and 17%, P = 0.7, respectively). Erectile dysfunction (IIEF-EF < 26) was more common in homosexual men relative to heterosexual men (24% vs. 12%, P = 0.02). High risk for female sexual dysfunction (FSFI < 26.55) was more common in heterosexual and bisexual women compared with lesbians (51%, 45%, and 29%, respectively, P = 0.005).

CONCLUSION

In this survey of highly educated young professionals, numerous similarities and some important differences in sexuality and sexual function were noted based on sexual orientation. It is unclear whether the dissimilarities represent differing relative prevalence of sexual problems or discrepancies in patterns of sex behavior and interpretation of the survey questions.

Impaired sexual function in patients with borderline personality disorder is determined by history of sexual abuse

INTRODUCTION

Patients suffering from a Borderline Personality Disorder (BPD) display altered sexual behavior, such as sexual avoidance or sexual impulsivity, which has repeatedly been linked to the sexual traumatization that occurs in a high percentage of BPD patients. Until now, no empirical data exists on whether these patients concomitantly suffer from sexual dysfunction.

AIM

This study investigates sexual function and the impact of sexual traumatization on this issue in women with BPD as compared to healthy women.

MAIN OUTCOME MEASURES

Sexual function was measured using the Female Sexual Function Index. Additionally, diagnoses were made with SCID II Interviews for Axis II and with the Mini International Neuropsychiatric Interview for Axis I disorders. The Post-traumatic Stress Diagnostic Scale for trauma evaluation was used. Sexual orientation was assessed by self-evaluation.

METHODS

Forty-five women with BPD as diagnosed according to DSM-IV criteria and 30 healthy women completed questionnaires on sexual function and sexual abuse history, as well as interviews on axis I and II disorders and psychotropic medication.

RESULTS

The BPD group showed a significantly higher prevalence of sexual dysfunction. Subgroup analyses revealed that BPD with concomitant sexual traumatization, and not BPD alone, best explains impaired sexual function. Sexual inactivity was mainly related to current major depression or use of SSRI medication. In sexually active participants, medication and symptoms of depression had no significant impact on sexual function.

CONCLUSIONS

Not BPD alone, but concomitant sexual traumatization, predicts significantly impaired sexual function. This may have a therapeutic impact on BPD patients reporting sexual traumatization.
