The Dual Control Model proposes that sexual arousal and related processes are dependent on the balance between sexual excitation and sexual inhibition, and that individuals vary in their propensity for these processes. This scoping review provides an overview and discussion of the questionnaires used to measure the propensities for sexual excitation and inhibition, their translation and validation in other languages, and their application in empirical research on topics ranging from sexual desire and arousal, sexual (dys)function, sexual risk taking, asexuality, hypersexuality, and sexual aggression. A total of 152 papers, published between 2009 and 2022 and identified using online databases, were included in this review.

Introduction: Measurement of salivary testosterone (Sal-T) to assess androgen status offers important potential advantages in epidemiological research. The utility of the method depends on the interpretation of the results against robustly determined population distributions, which are currently lacking.

Aim: To determine age-specific Sal-T population distributions for men and women.

Establishing the clinical significance of symptoms of sexual dysfunction is challenging. To address this, the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) introduced two new morbidity criteria (duration and symptom severity) to the existing criteria of distress. This study sought to establish the impact of these three criteria on the population prevalence of sexual function problems.

Background: The purpose of the linguistic validation of the Sexual Inhibition and Sexual Excitation Scales (SIS/SES) was to produce translated versions in five South Asian languages (Hindi, Urdu, Panjabi, Tamil and Sinhalese) that was "conceptually equivalent" to the original U.S. English version, for use in the Oxford Sexual Dysfunction Study (OSDS).

Introduction: Debate continues on whether or not male homosexuality (MH) is a result of biological or cultural factors. The debate persists despite the fact that these two sides have different abilities to create a scientific environment to support their cause. Biological theorists produced evidence, however, that these are not always robust.

In the United States, considerable attention has been directed to sexual behaviors of black and white adolescents, particularly age at first sexual experience and the prevalence of teenage pregnancies. More limited attention has been paid to comparing established sexual relationships in these two racial groups. In this study, we used a national probability sample to compare black (n = 251) and white (n = 544) American women, aged 20-65 years, who were in an established heterosexual relationship of at least 6 months duration.

The Dual Control Model proposes that sexual responses involve an interaction between sexual excitatory and sexual inhibitory processes. The model further postulates that individuals vary in their propensity for both sexual excitation and sexual inhibition, and that such variations help us to understand much of the variability in human sexuality. The development of psychometrically validated instruments for measuring such propensities for men (Sexual Inhibition/Sexual Excitation Scales) and for women (Sexual Excitation/Sexual Inhibition Inventory for Women) is described.

The past few years have seen an increased awareness of the relevance of studying the role of sexual response, emotion, and traits such as sensation seeking and the propensity for sexual inhibition in risky sexual behavior. The current study examined the association between self-reported sexual risk taking and psychophysiological response patterns in 76 heterosexual and homosexual men. Measures included genital, electrodermal, startle eyeblink, and cardiovascular responses, and stimuli included threatening (depicting coercive sexual interactions) and nonthreatening (depicting consensual sexual interactions) sexual film excerpts.

At this stage of our knowledge, it seems reasonable to assume that out-of-control sexual behavior results from a variety of etiological mechanisms associated with different behavioral patterns that share Goodman's two key features of addictive behavior: (1) a recurrent failure to control the sexual behavior; and (2) continuation of the behavior despite harmful consequences. Any overriding definition relevant to clinical management seems premature until we better understand the various patterns and their likely determinants. The concepts of "compulsivity" and "addiction" may have explanatory value in some cases, but are not helpful when used as general terms for this class of behavior problem.

The aim of this study was to examine whether changes in plasma androgen levels (total testosterone (T), free testosterone (FT), and dehydro-epiandrosterone-sulfate (DHEA-S)) induced by oral contraceptive (OC) use were related to changes in sexual interest or response or in mood. Sixty-one women provided blood samples and were assessed, using interviews and standardized questionnaires, prior to starting, and after 3 months on OCs (Ortho-Tricyclen, Ortho-Tricyclen-Lo, or Ortho-Cyclen, all containing the same progestagen, norgestimate). Significant decreases in T, FT, and DHEA-S were found after 3 months, although the extent of reduction was variable across women.

In view of the recent phase of political opposition to sex research and intense public interest in Alfred C. Kinsey, this paper considers the impact that Kinsey's research has had on the political process in the past 50 years. Initial reactions to Kinsey's research that remain relevant today include "normal" people don't participate in sex surveys, sex surveys are intended to promote homosexuality, and asking people about their sex lives in a nonjudgmental fashion promotes immorality.

The role of psychological and interpersonal factors in the treatment of erectile dysfunction (ED) with sildenafil or other oral therapies has not been sufficiently investigated. We conducted a pilot study of psychosocial predictors of pharmacotherapy treatment outcome and satisfaction in men with ED and their partners. Sixty-nine men with mild to moderate ED and their partners were enrolled in a multicenter, open-label, treatment trial with sildenafil.

Quantitative studies have shown that both straight and gay men with a low propensity for inhibition of sexual arousal are more likely to engage in unprotected sex in the face of risk. This article reports findings from an interview study of both straight and gay men focusing on the individual's experience of the impact of sexual arousal on risk management. The impact of the immediate post-ejaculatory period and the effects of condoms on sexual arousal are also considered.

The prevalence of erectile difficulties (ED) and problems with rapid ejaculation (RE) were studied in a convenience sample of gay men (n = 1379) and an age-matched sample of heterosexual men (n = 1558). ED was reported more frequently by gay men and RE more frequently by heterosexual men. The heterosexual men were more likely to be in exclusive relationships and those in a current relationship (exclusive or non-exclusive) were more likely to report ED than those not in a relationship.
