Genital Skin Diseases and Their Expression in Sexual Functionality

Sexual functionality acts as an important function of the individual, acting both physically and mentally to create a state of well-being and permitting procreation. A large number of mucosal and cutaneous ailments may affect the genial areas in both males and females, generally leading to local symptoms that impede the sexual act. Genital diseases, sometimes even without impairing the sexual function, may still alter the dynamics just because of the enormous psychological impact that occurs in these situations. We aim to review main dermatological disorders that alter normal function of the genitalia, as well as their physical mechanism by which the sexual functionality is changed

Sexual function, delivery mode history, pelvic floor muscle exercises and incontinence : a cross-sectional study six years postpartum

Background: There is controversy over the effect of mode of delivery, pelvic floor muscle exercises (PFME), incontinence and sexual function. Aim: To investigate the relationship of sexual function with delivery mode history, PFMEs and incontinence. Methods: This was a cross-sectional postal survey of women, six years post-partum, who had given birth in maternity units in Aberdeen, Birmingham and Dunedin and had answered a previous questionnaire. Each sexual function question was analysed separately by ANOVA. Results: At six years post-index delivery, 4214 women responded, of whom 2765 (65%) answered the optional ten sexual function questions. Although there was little association between delivery mode history and most sexual function questions, women who had delivered exclusively by caesarean section scored significantly better on the questions relating to their perception of vaginal tone for their own (P-value < 0.0001) and partner's (P-value 0.002) sexual satisfaction, especially when compared with women who had had vaginal and instrumental deliveries. Women who reported that they were currently performing PFME scored significantly better on seven questions. Women with urinary or faecal incontinence scored significantly poorer on all sexual function questions. Conclusions: Mode of delivery history appeared to have minimal effect on sexual function. Current PFME performance was positively associated with most aspects of sexual function, however, all aspects were negatively associated with urinary and faecal incontinence.The original study was supported by Wellbeing and the Health Research Council of New Zealand and the follow-up study by the Health Services Research Unit, which is core funded by a grant from the Chief Scientist Office of the Scottish Executive Health Department

Does Sexual Orientation Moderate between Partner Substance Use and Alcohol Consumption?

Does Sexual Orientation Moderate between Partner Substance Use and Alcohol Consumption? Jasmine Jones, Depts. of Psychology and African American Studies, with Dr. Jessica Salvatore, Dept. of Psychology Being with an antisocial partner can be challenging in various ways. Prior research suggests that involvement with an antisocial partner is associated with higher levels of substance use (Fleming, White, and Catalano 2010). Having a minority sexual orientation can also influence one’s own substance use. Prior research shows that individuals who identify as a sexual minority report higher levels of substance use compared to those who identify as heterosexual (Hughes, Wilsnack, Kantor 2016). Despite the robust associations between partner antisocial behavior, alcohol consumption, and sexual orientation there is little research looking at whether the association between having an antisocial partner and alcohol consumption differs as a function of sexual orientation. The aim for this study was to examine whether the association between a partner’s antisocial behavior and alcohol use differs as a function of sexual orientation. Participants came from “Spit for Science,” a university research opportunity for any freshman that would like to participate. Participants (N = 1502, 70.8% female) were invited to participate in surveys during their freshman year and every spring semester after. We used a subset based on participants who reported to be in a relationship during the spring semester of their freshman year. Consistent with prior research and our hypothesis, having a partner with higher substance use is associated with higher levels of alcohol consumption. Contrary to our hypothesis, we did not find evidence that partner substance use and alcohol consumption differed as a function of sexual orientation. Individuals who are involved with someone who consumes alcohol will consume more alcohol, however, this does not differ as a function of sexual orientation.https://scholarscompass.vcu.edu/uresposters/1317/thumbnail.jp

Contraceptive use and sexual function: a comparison of Italian female medical students and women attending family planning services

Objectives: The aims of the study were to understand how education relates to contraceptive choice and how sexual function can vary in relation to the use of a contraceptive method. Methods: We surveyed female medical students and women attending a family planning service (FPS) in Italy. Participants completed an online questionnaire which asked for information on sociodemographics, lifestyle, sexuality and contraceptive use and also included items of the Female Sexual Function Index (FSFI). Results: The questionnaire was completed by 413 women (362 students and 51 women attending the FPS) between the ages of 18 and 30 years. FSFI scores revealed a lower risk of sexual dysfunction among women in the control group who did not use oral hormonal contraception. The differences in FSFI total scores between the two study groups, when subdivided by the primary contraceptive method used, was statistically significant (p < 0.005). Women using the vaginal ring had the lowest risk of sexual dysfunction, compared with all other women, and had a positive sexual function profile. In particular, the highest FSFI domain scores were lubrication, orgasm and satisfaction, also among the control group. Expensive contraception, such as long-acting reversible contraception, was not preferred by this young population, even though such methods are more contemporary and manageable. Compared with controls, students had lower compliance with contraception and a negative attitude towards voluntary termination of pregnancy. Conclusion: Despite their scientific knowledge, Italian female medical students were found to need sexual and contraceptive assistance. A woman's sexual function responds to her awareness of her body and varies in relation to how she is guided in her contraceptive choice. Contraceptive counselling is an excellent means to improve female sexuality

Sexual function in 16- to 21-year-olds in Britain

Purpose: Concern about young people's sexuality is focused on the need to prevent harmful outcomes such as sexually transmitted infections and unplanned pregnancy. Although the benefit of a broader perspective is recognized, data on other aspects of sexuality, particularly sexual function, are scant. We sought to address this gap by measuring the population prevalence of sexual function problems, help seeking, and avoidance of sex in young people. Methods: A cross-sectional stratified probability sample survey (Natsal-3) of 15,162 women and men in Britain (response rate: 57.7%), using computer-assisted self-interviews. Data come from 1875 (71.9%) sexually active, and 517 sexually inactive (18.7%), participants aged 16–21 years. Measures were single items from a validated measure of sexual function (the Natsal-SF). Results: Among sexually active 16- to 21-year-old participants, 9.1% of men and 13.4% of women reported a distressing sexual problem lasting 3 months or more in the last year. Most common among men was reaching a climax too quickly (4.5%), and among women was difficulty in reaching climax (6.3%). Just over a third (35.5%) of men and 42.3% of women reporting a problem had sought help, but rarely from professional sources. Among those who had not had sex in the last year, just &gt;10% of young men and women said they had avoided sex because of sexual difficulties. Conclusions: Distressing sexual function problems are reported by a sizeable minority of sexually active young people. Education is required, and counseling should be available, to prevent lack of knowledge, anxiety, and shame progressing into lifelong sexual difficulties

Thyroid hormone receptors and ligand, tissue distribution and sexual behavior

The thyroid hormones (THs) triiodothyronine (T3) and tetraiodothyronine, or thyroxine (T4), not only dramatically impact on development and differentiation, but also on the sexual and reproductive function. There is large body of literature, in fact, on the effects of THs on the reproductive function in both humans (Poppe and Velkeniers, 2004; Wajner et al., 2009) and animals (Hapon et al., 2010; Nelson et al., 2011). For a long time the gonads were thought to be unresponsive to THs, but TH receptors (TR) were discovered in rat (Jannini et al., 1990; Palmero et al., 1988) and then in human testis (Jannini et al., 2000). In women, the association of menstrual disturbance with thyroid disease was described as early as 1840 by von Basedow, but the discovery of TRs in the ovary was carried out at the end of last century (Wakim et al., 1994b). Therefore, the link between thyroid and reproductive function was well established. Since then, research has shown that thyroid dysfunction is associated with an adverse effect on fertility, both in men (Wagner et al., 2009) and women (Dittrich et al., 2011). There is also evidence that THs can affect the sex steroid hormone axis (Bagamasbad and Denver, 2011), consequently sexual hormones and the pituitary gland can mediate the action of THs on the reproductive physiology. While the effects of THs on fertility have been widely studied, little is known about their influence on sexual function. In the last few years, an increasing number of evidences have shown the influence of THs on male sexual function, particularly on ejaculation control as well on desire and erectile function (Carani et al., 2005; Corona et al., 2012b; Di Sante et al., 2016). The female sexual function and the relationship with thyroid function is still less studied. Furthermore, studies conducted on animals have shown the presence of TRs in the male (Carosa et al., 2010) and female genitalia (Rodriguez-Castelan et al., 2017). Moreover, knockout mice for TRs showed alterations in sexual behavior (Dellovade et al., 2000). The purpose of this review is to summarize and discuss the available data on the influence of THs on male and female sexual function to understand the molecular mechanisms of the influence of the thyroid gland on sexual behavior and function

Assessment of sexual difficulties associated with multi-modal treatment for cervical or endometrial cancer: A systematic review of measurement instruments

Background: Practitioners and researchers require an outcome measure that accurately identifies the range of common treatment-induced changes in sexual function and well-being experienced by women after cervical or endometrial cancer. This systematic review critically appraised the measurement properties and clinical utility of instruments validated for the measurement of female sexual dysfunction (FSD) in this clinical population. Methods: A bibliographic database search for questionnaire development or validation papers was completed and methodological quality and measurement properties of selected studies rated using the Consensus-based Standards for the selection of health Measurement Instrument (COSMIN) checklist. Results: 738 articles were screened, 13 articles retrieved for full text assessment and 7 studies excluded, resulting in evaluation of 6 papers; 2 QoL and 4 female sexual morbidity measures. Five of the six instruments omitted one or more dimension of female sexual function and only one instrument explicitly measured distress associated with sexual changes as per DSM V (APA 2013) diagnostic criteria. None of the papers reported measurement error, responsiveness data was available for only two instruments, three papers failed to report on criterion validity, and test-retest reliability reporting was inconsistent. Heterosexual penile-vaginal intercourse remains the dominant sexual activity focus for sexual morbidity PROMS terminology and instruments lack explicit reference to solo or non-coital sexual expression or validation in a non-heterosexual sample. Four out of six instruments included mediating treatment or illness items such as vaginal changes, menopause or altered body image. Conclusions: Findings suggest that the Female Sexual Function Index (FSFI) remains the most robust sexual morbidity outcome measure, for research or clinical use, in sexually active women treated for cervical or endometrial cancer

Evidence for the stress-linked immunocompetence handicap hypothesis in humans

Secondary sexual traits that develop under the action of testosterone, such as masculine human male facial characteristics, have been proposed to signal the strength of the immune system due to the sex hormone's immunosuppressive action. Recent work has suggested that glucocorticoid stress hormones may also influence expression of such sexual signals due to their effects on immune function. Precise roles, however, remain unclear. Here we show positive relationships between testosterone, facial attractiveness and immune function (antibody response to a hepatitis B vaccine) in human males, and present some preliminary evidence that these relationships are moderated by naturally co-occurring cortisol (a glucocorticoid stress hormone involved in the fight-or-flight response). We conclude that our results provide support for a role of glucocorticoids in hormonally mediated sexual selection

Predicting sexual problems in women: The relevance of sexual excitation and sexual inhibition

This is the post-print version of the article. The official published version can be obtained from the link below.Data from a non-clinical sample of 540 heterosexual women were used to examine the relationships between scores on the Sexual Excitation/Sexual Inhibition Inventory for Women (SESII-W) and ratings of current sexual problems, lifetime arousal difficulty, lifetime orgasm difficulty, and lifetime problems with low sexual interest. Multiple regression analyses also included several demographic/background variables as predictors: age, full-time employment, completed college, children in household, married, health ratings, importance of sex, and whether the woman was in a sexual relationship. The strongest statistical predictors of both current and lifetime sexual problems were the SESII-W inhibition factors Arousal Contingency and Concerns about Sexual Function. Demographic factors did not feature largely in any of the models predicting sexual problems even when statistically significant relationships were found. If future research supports the predictive utility of the SESII-W in identifying women who are more likely to experience sexual difficulties, these scales may be used as prognostic factors in treatment studies.This study was funded, in part, by a grant from the Lilly Centre for Women's Health

Thermal signatures of human pheromones in sexual and reproductive behaviour

Chemically mediated sexual communication in humans has been largely neglected due to its non-conscious and relatively concealed nature. However, menstrual cycle synchronisation, puberty onset in young pre-pubertal girls exposed to their stepfather, and consanguinity avoidance suggest a function in the physiological regulation of sexual and reproductive behaviour in humans. These phenomena are related to activation of the limbic system by pheromones. On the basis of sexually dimorphic activation of brain hypothalamic areas and the control of body temperature via the hypothalamus, our hypothesis is that human sexual pheromones can induce thermal effects that can be revealed by high-resolution thermal infrared imaging. Here we show that in women, male sexual pheromones induce thermal effects that are linked to the ovarian cycle. These findings suggest a dramatic influence of pheromones on human sexual and reproductive behaviour through neuroendocrine brain control, established on the plesiomorphic nature of chemical communication across species
