Distribution of the Brief Male Sexual Inventory in community men.

The objectives of the study were to characterize male sexual functioning as related to age in community-dwelling older men. In 1989, a random sample of men aged 40-79 y (n=2115) without prior prostate surgery, prostate cancer, or other conditions known to affect voiding function (except benign prostatic hyperplasia) was invited (55% agreed) to participate in the Olmsted County Study of Urinary Symptoms and Health Status Among Men. In 1996, a previously validated male sexual function questionnaire was administered to the cohort. The questionnaire has 11 questions measuring sexual drive (two questions); erectile function (three) and ejaculatory function (two), as well as assessing problems with sex drive, erections, or ejaculation (three); and overall satisfaction with sex life (one). Each question is scored on a scale of 0-4, with higher scores indicating better functioning. Cross-sectional age-specific means (+/-s.d.) for drive, erections, ejaculation, problems, and overall satisfaction declined from 5.2 (+/-1.5), 9.8 (+/-2.5), 7.4 (+/-1.4), 10.7 (+/-2.2), and 2.6 (+/-1.0), respectively, for men in their 40s to 2.4 (+/-1.6), 3.3 (+/-3.4), 3.6 (+/-3.2), 7.7 (+/-3.8), and 2.1 (+/-1.2) for men 70 y and older (all P<0.001). The cross-sectional decline in function with age was not constant, with age-related patterns differing by domain. The percentage of men reporting erections firm enough to have intercourse in the past 30 days declined from 97% (454/468) among those in their 40s to 51% (180/354) among those in their 80s (P&<0.001). In age-adjusted analyses, men reporting regular sexual partners had statistically significantly higher levels of sex drive, erectile function, ejaculatory function, and overall satisfaction than those who did not report regular sexual partners. Sexual drive, erectile functioning, ejaculatory functioning, and overall sexual satisfaction in men show somewhat differing cross-sectional patterns of decline with advancing age. Active sexual functioning is maintained well into the 80s in a substantial minority of community-dwelling men.

Update on central function relevant to sex: remodeling the basis of drug treatments for sex and the brain.

Sexual function draws on a complex network of peripheral and central neural pathways. The standard focus on erectile difficulties and peripheral therapies has been highly successful clinically but there are many unresolved issues in men and newly discussed issues in women that will likely benefit from improved understanding of the central nervous system and sexual function. The spectrum of future therapies, based on evolving central neurophysiological understanding, will include the management of problems related to orgasm, ejaculation, desire, motivation, anxiety, and pleasure. This new range of therapies will employ old and new neurochemicals and pathways singly or in combination. The capability of hormones to modulate many of the sexual pathways will also contribute to the rise of multiagent therapy. The expanded understanding, in combination with enhanced imaging technologies, will renew the role of diagnosis and cause-specific treatment.

The human sexuality education of physicians in North American medical schools.

Individuals seeking treatment for sexual problems frequently would like to turn to a source they consider knowledgeable and worthy of respect, their doctor. The objective was to assess how well the 125 schools of medicine in the United States and the 16 in Canada prepare physicians to diagnose and treat sexual problems. A prospective cohort study was carried out. The main outcome results were description of the medical educational experiences, teaching time, specific subject areas, clinical programs, clerkships, continuing education programs in the domain of human sexuality in North American medical schools. The results were as follows. There were 101 survey responses (71.6%) of a potential of 141 medical schools (74% of United States and 50% of Canadian medical schools). A total of 84 respondents (83.2%) for sexuality education used a lecture format. A single discipline was responsible for this teaching in 32 (31.7%) schools, but a multidisciplinary team was responsible in 64 (63.4%) schools (five schools failed to respond to the question). The majority (54.1%) of the schools provided 3-10 h of education. Causes of sexual dysfunction (94.1%), its treatment (85.2%) altered sexual identification (79.2%) and issues of sexuality in illness or disability (69.3%) were included in the curriculum of 96 respondents. Only 43 (42.6%) schools offered clinical programs, which included a focus on treating patients with sexual problems and dysfunctions, and 56 (55.5%) provided the students in their clerkships with supervision in dealing with sexual issues. In conclusion, expansion of human sexuality education in medical schools may be necessary to meet the public demand of an informed health provider.

Sexual health innovations in undergraduate medical education.

Recent national and global initiatives have drawn attention to the importance of sexual health to individuals' well-being. These initiatives advocate enhancement of efforts to address this under-represented topic in health professions curricula. University of Massachusetts Medical School (UMMS) has undertaken a comprehensive effort to develop an integrated curriculum in sexual health. The UMMS project draws upon the expertise of a multidisciplinary faculty of clinicians, basic scientists, a medical ethicist, and educators. This article describes the project's genesis and development at UMMS, and reports on three innovations in sexual health education implemented as part of this endeavor.

A comprehensive approach to enhancing sexual health education in the Case Western Reserve University School of Medicine.

We report on the Sexual Health Curriculum Enhancement project at Case Western Reserve University School of Medicine. Using a US dollars 100000 grant from Pfizer Pharmaceuticals, Inc., we have developed and are in the process of implementing a comprehensive, cross-disciplinary and innovative curriculum that is based on three primary objectives for teaching sexual health: attitude change, behavior change, and knowledge acquisition. Five general strategies to incorporate specific sexual health content into the medical school curriculum have been implemented: (1). Faculty Development; (2). Additional Didactics; (3). Cased-Based Learning; (4). Testing and Assessment; and (5). Electronic (Computer/Web-Based Enhancements).

Medical students' perceptions of sexual health issues prior to a curriculum enhancement.

The objectives were to compare first, second and third year medical students on self-perceived sexual health knowledge, comfort in addressing sexual health problems, and attitudes towards the importance of addressing sexual health issues with patients as part of a sexual health medical curriculum enhancement project. A paper-and-pencil questionnaire survey was designed and administered to first and second year medical students at the start of the fall semester, resulting in high participation rates for both years (98% and 86%, respectively). Third year students were surveyed through an on-line version of the questionnaire yielding a lower response rate (52%). Multivariate statistical analyses were used to compare knowledge, comfort and attitudes by year in medical school. Results were as follows: As might be expected, sexual health knowledge and comfort in addressing sexual health problems increased linearly from first to third year (P<0.01) for all questions. Unexpectedly, second year students had significantly higher scores on questions assessing attitudes towards the importance of addressing sexual health issues than either first or third year students (P<0.001). Female medical students reported that addressing sexual health issues with patients was significantly more important than did male medical students; however, male students reported higher levels of self-reported knowledge and comforting related to sexual health issues than did female students in a number of areas. In conclusion, knowledge gained from this survey was used to finalize the design of an enhanced, integrated curriculum on sexual health for medical students. Further investigation of gender differences related to training medical students in this area is suggested.

Sexual function in women with coronary artery disease: a preliminary study.

We investigated sexual function in female patients with coronary artery disease (CAD). A total of 20 consecutive female patients (38.2+/-3.8 years) with CAD diagnosed by coronary angiography and 15 healthy subjects (37.9+/-5.4 years) were enrolled in this study. The Female Sexual Function Index (FSFI) was used to assess sexual function in all the participants. Women with psychiatric disorders, gynecologic and systemic diseases that may affect sexual function were excluded from the study. The other exclusion criteria were usage of antidepressants and drugs affecting sexual function. Patients with CAD and healthy women were comparable in age, body mass index and education level. Female sexual dysfunction (FSD) was diagnosed in 12 of 20 women with CAD (60%), whereas five of 15 healthy women (33.3%) were found to have FSD (P<0.05). Patients with CAD had a significantly lower number of sexual intercourse episodes per month than healthy women volunteers (2.24 versus 5.2, respectively; P<0.05). The FSFI total score was clearly significantly decreased in the CAD group compared with that in healthy controls (17.8+/-2.9 and 26.0+/-4.8, P=0.001). When the subscores of each domain of FSFI were evaluated, all the subscores of FSFI, except the satisfaction domain, in patients with CAD were significantly lower than those of healthy subjects (P<0.05). This preliminary study demonstrates that female patients with CAD have distinct sexual dysfunction compared with healthy controls. Women with CAD should be evaluated also in terms of sexual function to provide better quality of life.

Polymorphisms in the dopamine D4 receptor gene (DRD4) contribute to individual differences in human sexual behavior: desire, arousal and sexual function.

Although there is some evidence from twin studies that individual differences in sexual behavior are heritable, little is known about the specific molecular genetic design of human sexuality. Recently, a specific dopamine D4 receptor (DRD4) agonist was shown in rats to induce penile erection through a central mechanism. These findings prompted us to examine possible association between the well-characterized DRD4 gene and core phenotypes of human sexual behavior that included desire, arousal and function in a group of 148 nonclinical university students. We observed association between the exon 3 repeat region, and the C-521T and C-616G promoter region SNPs, with scores on scales that measure human sexual behavior. The single most common DRD4 5-locus haplotype (19%) was significantly associated with Desire, Function and Arousal scores. The current results are consistent with animal studies that show a role for dopamine and specifically the DRD4 receptor in sexual behavior and suggest that one pathway by which individual variation in human desire, arousal and function are mediated is based on allelic variants coding for differences in DRD4 receptor gene expression and protein concentrations in key brain areas.

Exploring sexual and relationship possibilities for people with psychosis--a review of the literature.

This review examines the literature on sex and relationship issues in the context of serious and persistent mental health problems. It identifies gaps in the research and highlights key issues needing further investigation. The available published documents have been identified, which contain information, ideas, data and evidence on the topic. A critical analysis of the subject, through the examination of the various documents, is provided. The main themes that emerged included HIV/AIDS, medication and sexual dysfunction, sexuality needs, intimate relationships, family planning, policies and sex education. Several subthemes are discussed and include needs assessment, stigma and loneliness. The key findings highlight the lack of systematic studies in the UK, especially regarding the subjective views of patients in determining need and the subsequent development of appropriate plans of care. The author argues that future mental health research needs to go beyond investigating perceived 'risky' behaviours and should include potential therapeutic responses in all areas of sexuality. Further recommendations are made in terms of nurse education particularly the inclusion of psychosexual aspects in future pre- and postregistration curricula. This paper may be of interest to service users, mental health practitioners working alongside people with serious and persistent mental health problems as well as educators, researchers and policy makers.

Erectile function and nocturnal penile tumescence in patients with prostate cancer undergoing luteinizing hormone-releasing hormone agonist therapy.

BACKGROUND: Luteinizing hormone-releasing hormone (LHRH) agonists have been widely used as effective agents in endocrine therapy for prostate cancer. Continuous administration of the drug results in profound suppression of testicular androgen production. However, the side effects on erectile function have not been fully investigated. METHODS: We studied the influences of testosterone suppression on male sexual function and nocturnal penile tumescence in nine sexually active patients with prostate cancer who were treated with an LHRH agonist. RESULTS: Following reduction of serum testosterone concentrations to a castration level by the administration of the LHRH agonist, sexual desire, sexual interest and sexual intercourse were totally annulled, with significant changes in frequency, magnitude, duration and rigidity of nocturnal erections observed in all patients. CONCLUSIONS: These results demonstrate that the LHRH agonist strongly suppresses erectile function and sexual activity. Taking into account the quality of sexual function for relatively young and sexually active patients and their partners, it is necessary to establish effective modalities that minimize the adverse effects on sexual function for the treatment of patients with prostate cancer.

Sexual function and childbirth.

OBJECTIVE: This manuscript reviews the potential impact of cesarean delivery on maternal sexual function. FINDING: The majority of new mothers resume intercourse within the first 3 months after delivery. However, during the first year after delivery, the majority of women experience at least one problem related to sexual function. The question with respect to maternal-choice cesarean is whether this obstetrical intervention affects maternal sexual function. We review the available evidence regarding sexual function after cesarean delivery and present several plausible mechanisms by which route of delivery could impact long-term postpartum sexual function. CONCLUSION: Further research is needed to investigate whether maternal-choice cesarean delivery affects female sexual function.

Seizures, hormones and sexuality.

Sexual disorders (both hyposexuality and sexual dysfunction) are common in people with epilepsy, occurring in up to two-thirds of patients. However, characteristically, patients do not spontaneously report these problems. Nocturnal penile tumescence testing suggests that the erectile dysfunction has a neurophysiological component. The aetiology remains uncertain but is likely to be multifactorial, involving neurological, endocrine, iatrogenic, cognitive, psychiatric and psychosocial factors. Epilepsy-related factors include the age of onset/duration of epilepsy along with the seizure type and focus. In addition, seizure frequency might be relevant as successful epilepsy surgery can result in an improvement in sexual functioning despite remaining on anticonvulsant medication. Endocrine changes (raised sex hormone binding globulin and reduced free testosterone) have been reported in men with epilepsy, especially when treated with hepatic-enzyme inducing antiepileptic drugs. Studies have not been performed evaluating anticonvulsants that do not induce hepatic enzymes such as lamotrigine. The association between these endocrine changes and hyposexuality is not known. The relationship between seizures, hormones and anticonvulsant medication in women is explored, focusing on issues such as catamenial epilepsy, the menopause, hormone replacement therapy and the polycystic ovarian syndrome. Suggestions for future research and treatment issues are discussed.

Sexuality and reproductive issues in children with myelomeningocele.

Recent advancements in surgical and medical therapies have improved the life expectancy of children with myelomeningocele. Yet, there has been a contrasting lack of improvement with regards to sexual function and reproductive issues that continue to infantilize this population. This article identifies five major risk factors that contribute to these delays which invariably lead to irreversible emotional trauma if they are not addressed early in childhood. Adequate psychosexual education of myelomeningocele patients and their families is a tremendous societal challenge. But, only with education will there be trends away from policies of isolation to those that reinforce community integration of the physically disabled.

Vaginal changes and sexuality in women with a history of cervical cancer.

BACKGROUND: In women with cervical cancer, treatment causes changes in vaginal anatomy and function. The effect of these changes on sexual function and the extent, if any, to which they distress women are not known. METHODS: In 1996 and 1997, we attempted to contact 332 women with a history of early-stage cervical cancer (age range, 26 to 80 years) who had been treated in 1991 and 1992 at the seven departments of gynecological oncology in Sweden and 489 women without a history of cancer (controls) to ask them to answer an anonymous questionnaire about vaginal changes and sexual function. RESULTS: We received completed questionnaires from 256 of the women with a history of cervical cancer and 350 of the controls. A total of 167 of 247 women with a history of cancer (68 percent) and 236 of 330 controls (72 percent) reported that they had regular vaginal intercourse. Twenty-six percent of the women who had cancer and 11 percent of the controls reported insufficient vaginal lubrication for sexual intercourse, 26 percent of the women who had cancer and 3 percent of the controls reported a short vagina, and 23 percent of the women who had cancer and 4 percent of the controls reported an insufficiently elastic vagina. Twenty-six percent of the women who had cancer reported moderate or much distress due to vaginal changes, as compared with 8 percent of the women in the control group. Dyspareunia was also more common among the women who had cervical cancer. The frequency of orgasms and orgasmic pleasure was similar in the two groups. Among the women who had cervical cancer, the type of treatment received had little if any effect on the prevalence of specific vaginal changes. CONCLUSIONS: Women who have been treated for cervical cancer have persistent vaginal changes that compromise sexual activity and result in considerable distress.

Sexual desire in later life.

The has been relatively little research on sexuality in later life, particularly among persons over 60 years of age. The existing literature consists of studies of small samples, much of it from a biomedical perspective. This literature suggests that age, hormone levels, specific illnesses, and various medications negatively affect sexual functioning in older persons. The study reports results from a survey of a large sample (N=1,384) of persons age 45 and older that included measures of a variety of biological, psychological and social factors that potentially influence sexual functioning. We report bivariate and multivariate analysis conducted separately for women and men. We find that the principal influences on strength of sexual desire among women are age, the importance of sex to the person, and education. In this sample of the population of older persons, attitudes are more significant influences on sexual desire than biomedical factors.

A study of the sexuality of opiate addicts.

The influence of heroin use on sexual behavior was studied in individuals attending a drug abuse program in Porto, Portugal. As we expected, drug abuse was found mainly to adversely affect sexual behavior. A minority of patients reported improvement in sexual behavior with heroin use. Almost all patients remained sexually active and took no special precautions to prevent sexually transmitted diseases. Some patients reported heroin-related sexual effects to be a motivating factor for ceasing drug abuse.

Androgens and male sexual function: a review of human studies.

The scope of this article will be a review and brief discussion of recently gathered information on androgens and sexual behavior in men. It will include experimental observations on the covariance between androgens, mainly testosterone, and sexual functioning in normal heterosexual men and studies on sexual dysfunction and homo-sexual behavior. The effects of castration, hypogonadal conditions, hormonal replacement, and endogenous testosterone variations on sexual behavior are examined. Further psychoendocrine studies, are necessary to evaluate the role of gonadal hormone production in impotency. Current pharmacological research does not furnish specific evidence, that the administration of androgens or preparations that stimulate the secretion of endogenous androgens have beneficial effects on functional impotence. After reviewing the studies on male homosexuality and androgen levels, the article concludes that it has not been established that homosexual men are characterized by abnormalities in plasma testosterone.
