The impact of study design on prevalence estimates of Female Sexual Dysfunction

The impact of study design on prevalence estimates of Female Sexual Dysfunction

Despite increasing research, the true prevalence of Female Sexual Dysfunction (FSD) remains a contentious issue. Previous research suggests that aspects of study design affect the reported prevalence of FSD. We compare commonly used instruments for assessing FSD.

A random sample of 240 Australian women aged 20-70 participated in this population based, cross-sectional study. A questionnaire mailed to women across Australia included four instruments for assessing FSD. The Sexual Function Questionnaire combined with the Female Sexual Distress Scale (SFQ-FSDS) was employed as a standard, validated instrument. Alternative instruments were the SFQ alone and two modified versions of a set of questions originally developed by Laumann et al.

When assessed by the SFQ-FSDS, prevalence estimates (and 95% confidence intervals) of Hypoactive Sexual Desire Disorder, Female Sexual Arousal Disorder (genital subtype), Female Orgasmic Disorder, and Dysparunia were 16%(11-20%), 8%(4-11%), 9%(6-13%), 2%(0.1-3%) respectively. The prevalence estimates of these same disorders obtained using alternative instruments were 32-55%, 17-35%, 17-33% and 3-25% respectively. The sensitivity of alternative instruments varied widely (0 to 1.0). Specificities ranged from 0.51 to 0.99. Positive predictive values ranged from 0 to 0.57. Negative predictive values were all above 0.90. Changing the time span for recalling sexual experiences in an instrument altered the prevalence estimates, sensitivity and specificity. 32% of women with low desire, 31% with low genital arousal, 36% with orgasm difficulty and 57% with sexual pain were sexually distressed.

Over a third of women who were classified as suffering FSD by alternative instruments did not have FSD when assessed by SFQ-FSDS.
Alternative instruments produced substantially higher prevalence estimates of FSD and identified different groups of women. Consequently, the instruments researchers choose to assess FSD may affect both the prevalence estimates and risk factors they report.

Treatment Options for female sexual dysfunction

Treatment Options for female sexual dysfunction

Female Sexual Dysfunction remains an evolving area lending itself to various levels of diagnostic and treatment approaches. The shift made by the recent DSM V classification translated into a need for more sophisticated and integrated provision of care to women seeking help. However, the mainstay of management of FSD continues to rest on non-hormonal, hormonal, and psycho-cognitive algorithms. Essential to that is a proper history taking and patient interview capturing all aspects of a woman’s life, physical, and psychological status.

Male and female sexual dysfunctions: Results of four years of clinical activty

The main purpose of this study is to examine the requests presented by a sample of patients in an institute of clinical sexology in Rome. This study analyses the clinical reports of 380 patients, 184 women and 196 men, ages 17-70 years (mean=34.99; SD=10.767), attending the institute between 2004 and 2008. The sample was divided into groups, males and females who required consultation for themselves and subjects who asked for a couple’s consultation. The valuation methods to classify sexual dysfunctions are referred to DSM-IV-TR. Descriptive statistics were used to analyze data.
