Gao D, Chen C, Wu Z, Li H, Xie C, Tang B. The association between serum 25-hydroxyvitamin D levels and erectile dysfunction: a two-sample Mendelian randomization analysis. Int J Impot Res 2024:10.1038/s41443-024-00862-1. [PMID: 38429499 DOI: 10.1038/s41443-024-00862-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 02/15/2024] [Accepted: 02/21/2024] [Indexed: 03/03/2024]
Abstract
Considering that vascular endothelial cell dysfunction is the pathological basis of erectile dysfunction (ED), and recognizing the beneficial effects of 25-hydroxyvitamin D (25(OH)D) on vascular endothelial cell protection, the researchers diligently investigated the causal relationship between serum 25(OH)D levels and ED. However, inconsistent clinical evidence has left the association between serum 25(OH)D levels and ED unclear. The objective of this work was to employ Mendelian randomization (MR) analysis to ascertain the potential causal relationship between serum 25(OH)D levels and ED. We conducted a two-sample MR analysis utilizing data from publicly available genome-wide association studies (GWASs). The primary analysis method for the MR analysis was the inverse-variance weighted (IVW) method, supplemented by the MR-Egger and weighted median methods. In addition, we evaluated heterogeneity with Cochran's Q test, assessed pleiotropy using the MR-Egger intercept test, and performed a leave-one-out analysis to identify single-nucleotide polymorphisms (SNPs) with potential effects. Outliers were detected using MR-pleiotropy residual sum and outlier (MR-PRESSO). Genetically predicted serum 25(OH)D levels were not found to be causally associated with ED in IVW method (OR = 1.028, 95% CI = 0.845-1.250, P = 0.785), MR-Egger method (OR = 1.057, 95% CI = 0.782-1.430, P = 0.720), and weighted median method (OR = 1.225, 95% CI = 0.920-1.633, P = 0.165). The results of sensitivity analyses reinforced our conclusion, indicating no evidence of heterogeneity or directional pleiotropy. In summary, our findings do not substantiate a genetic-level causal link between serum 25(OH)D levels and the prevalence of ED. Nonetheless, future research, including larger MR studies, clinical trials, and additional observational studies, is essential to validate and reinforce the outcomes of our present study.

Investigating self-reported efficacy of lifestyle medicine approaches to tackle erectile dysfunction: a cross-sectional eSurvey based study. BMC Urol 2023; 23:15. [PMID: 36740686 PMCID: PMC9901095 DOI: 10.1186/s12894-023-01180-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 01/27/2023] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Erectile dysfunction (ED) is the most common sexual dysfunction in men. Some types of ED are amenable to treatment using lifestyle medicine approaches with or without pharmacotherapy. AIM Investigate self-reported efficacy of lifestyle medicine approaches to tackle ED. METHODS A cross-sectional online survey of 1177 community dwelling adults explored the prevalence and methods used to tackle ED in the community setting. We examined differences between participants with and without ED. Variables associated with ED in univariable analyses were included in a multivariable logistic regression to identify variables independently associated with the condition. OUTCOMES Self-reported measure: perceived effectiveness of lifestyle medicine interventions to tackle ED. RESULTS Most respondents (76.5%) had experienced ED, and this was associated with having a long-term condition, taking anti-hypertensive medication, hypercholesterolaemia and obesity. Medication was the most common management strategy overall (65.9%), followed by stress management (43.5%) and weight loss (40.4%). Over half (53.9%) did not use any lifestyle modification strategies to tackle ED. Only 7.0% of ED sufferers received a mental health assessment and 29.2% received other tests (e.g., blood test, medical imaging) by GPs. Cardiovascular training was identified as the best rated strategy by its users (37.8%). Supplements (35.1%) and weight training/physical activity (32.6%) were also positively rated. CLINICAL IMPLICATIONS Structured education to general practitioners and community dwelling adults about the impact of lifestyle behaviour modification and how this could influence the appearance or trajectory of ED could help improve personal choice when tackling ED. STRENGTHS AND LIMITATIONS To our knowledge, this is the first study to collect eSurvey responses from community dwelling adults to gauge their reliance and perceived effectiveness of lifestyle medicine approaches to tackle ED. The principal limitation was the lack of follow-up, and not recording other information including lifestyle factors such as nutrition, smoking, and the use of alcohol and recreational drugs, which may have enabled a fuller exploration of the factors that could influence the primary outcome measures examined. CONCLUSION Despite the high prevalence of ED, there is not enough awareness in the community setting about effective and low-cost lifestyle medicine strategies, including cardiovascular training and the use of supplements and weight training, to help tackle this common condition.

Abstract
OBJECTIVE To evaluate the longitudinal association between plant-based diet index (PDI) score and incident erectile dysfunction (ED). MATERIALS AND METHODS We conducted a prospective analysis of 21 942 men aged 40 to 75 years who were enrolled in the Health Professionals Follow-Up Study. ED was assessed with questionnaires every 4 years starting in 2000. Dietary data were collected via validated food frequency questionnaires completed every 4 years and were used to calculate total PDI scores, as well as healthy (hPDI) and unhealthy (uPDI) subscores. Multivariable Cox proportional hazards models were used to compute hazard ratios (HRs) for incident ED. All models were stratified by age (<60, 60 to <70, ≥70 years). RESULTS Among men aged 60 to <70 years, hPDI was inversely associated with incident ED. Those in the highest quintile of hPDI in that age group had an 18% lower risk of ED (HR 0.82, 95% confidence interval (CI) 0.73-0.91; P-trend <0.001) compared to those in the lowest quintile. Conversely, uPDI was positively associated with ED in men aged <60 years (HR 1.27, 95% CI 1.01-1.60; P-trend = 0.02). CONCLUSIONS Encouraging a healthy plant-based diet may be an environmentally sustainable intervention for men interested in maintaining erectile function.

Endothelial Dysfunction, Erectile Deficit and Cardiovascular Disease: An Overview of the Pathogenetic Links. Biomedicines 2022; 10:biomedicines10081848.

Abstract
Erectile dysfunction (ED) is a condition with multifactorial pathogenesis, quite common among men, especially those above 60 years old. A vascular etiology is the most common cause. The interaction between chronic inflammation, androgens, and cardiovascular risk factors determines macroscopically invisible alterations such as endothelial dysfunction and subsequent atherosclerosis and flow-limiting stenosis that affects both penile and coronary arteries. Thus, ED and cardiovascular disease (CVD) should be considered two different manifestations of the same systemic disorder, with a shared aetiological factor being endothelial dysfunction. Moreover, the penile arteries have a smaller size compared with coronary arteries; thus, for the same level of arteriopathy, a more significant blood flow reduction will occur in erectile tissue compared with coronary circulation. As a result, ED often precedes CVD by 2–5 years, and its diagnosis offers a time window for cardiovascular risk mitigation. Growing evidence suggests, in fact, that patients presenting with ED should be investigated for CVD even if they have no symptoms. Early detection could facilitate prompt intervention and a reduction in long-term complications. In this review, we provide an overview of the pathogenetic mechanisms behind arteriogenic ED and CVD, focusing on the role of endothelial dysfunction as the common denominator of the two disorders. Developed algorithms that may help identify those patients complaining of ED who should undergo detailed cardiologic assessment and receive intensive treatment for risk factors are also analyzed.

Abstract
IMPORTANCE Erectile dysfunction, especially in younger men, is an early sign of cardiovascular disease and may decrease quality of life. Men may be motivated to adopt a healthy dietary pattern if it lowers their risk of erectile dysfunction. OBJECTIVE To assess the association between adherence to a diet quality index based on healthy dietary patterns and erectile dysfunction in men. DESIGN, SETTING, AND PARTICIPANTS This population-based prospective cohort study included men from the Health Professionals Follow-up Study with follow-up from January 1, 1998, through January 1, 2014. Participants included US male health professionals aged 40 to 75 years at enrollment. Men with erectile dysfunction or a diagnosis of myocardial infarction, diabetes, stroke, or genitourinary cancer at baseline were excluded. Analyses were completed in February 2020. EXPOSURES A food frequency questionnaire was used to determine nutrient and food intake every 4 years. MAIN OUTCOMES AND MEASURES Diet quality was assessed by Mediterranean Diet score and the Alternative Healthy Eating Index 2010 score, with higher scores indicating healthier diet. Dietary index scores were cumulatively updated from 1986 until men developed erectile dysfunction, cardiovascular disease, died, or were lost to follow-up. Incident erectile dysfunction was assessed with questionnaires in 2000, 2004, 2008, and 2012. Hazard ratios (HRs) by prespecified categories or quintiles of dietary index scores were estimated using Cox proportional hazards regression analyses stratified by age. RESULTS Among 21 469 men included in analysis, mean (SD) age at baseline was 62 (8.4) years. During a mean (SD) follow-up of 10.8 (5.4) years and 232 522 person-years, there were 968 incident erectile dysfunction cases among men younger than 60 years, 3703 cases among men aged 60 to less than 70 years, and 4793 cases among men aged 70 years or older. Men younger than 60 years and in the highest category of the Mediterranean Diet score had the lowest relative risk of incident erectile dysfunction compared with men in the lowest category (HR, 0.78; 95% CI, 0.66-0.92). Higher Mediterranean diet scores were also inversely associated with incident erectile dysfunction among older men (age 60 to <70 years: HR, 0.82; 95% CI, 0.76-0.89; age ≥70 years: HR, 0.93; 95% CI, 0.86-1.00). Men scoring in the highest quintile of the Alternative Healthy Eating Index 2010 also had a lower risk of incident erectile dysfunction, particularly among men age younger than 60 years (quintile 5 vs quintile 1: HR, 0.78; 95% CI, 0.63-0.97). CONCLUSIONS AND RELEVANCE This cohort study found that adherence to healthy dietary patterns was associated with a lower risk for erectile dysfunction, suggesting that a healthy dietary pattern may play a role in maintaining erectile health.

Abstract
BACKGROUND Sexual dysfunction is frequently seen in alcohol-use disorders. The available research on this topic has studied erectile dysfunction and premature ejaculation using nonvalidated scales. This study was undertaken to study the other major domains of sexual dysfunction, namely sexual desire, orgasmic dysfunction and satisfaction, and their association with sociodemographic factors. MATERIALS AND METHODS A cross-sectional descriptive study design was used and 78 male patients were recruited. The assessment was conducted using a specially designed intake pro forma, International Index of Erectile Function (IIEF-15) Scale, DSM-5 and International Classification of Disease, 10th revision, diagnostic criteria for research. A correlation between the amount of alcohol consumed and its effect on various domains of sexual dysfunction was also carried out using Pearson's correlation coefficient. RESULTS The sociodemographic profile was studied in association with the overall (total) IIEF-15 subscale using analysis of variance (ANOVA). Statistically significant differences were observed among age groups, education subgroups, marital disharmony, years of alcohol use, and lifetime alcohol use. Further, since the values of ANOVA were significant, Tukey's post hoc analysis was carried out which showed a statistically significant difference among the groups. Various domains of sexual dysfunction showed a strongly negative correlation for overall IIEF subscale followed by intercourse satisfaction, sexual desire, and orgasmic function with years of alcohol use and lifetime alcohol use. CONCLUSION Sexual dysfunction in alcohol dependence patients was significantly associated with a family history of paternal alcohol abuse, lower educational background, increasing age, and marital disharmony. This study also found a strongly negative correlation between various domains of sexual functioning and years of alcohol use/lifetime alcohol use.

Abstract
Background: Increasing age as a risk factor for erectile dysfunction (ED) is in most studies assumed to be a linear function. If this is not the case the assumption could lead to bias, e.g. when men of different ages are compared in interventional studies on ED. Objective: To explore the risk of developing ED over time for men from different age groups. Materials and methods: A questionnaire was sent to a number of male residents in Gothenburg, Sweden, in 1992 (n = 10,458). Men were randomly selected according to year of birth to obtain several cohorts at 5-year intervals of ages 45, 50, 55 years, etc., up to the age of 85 or older. In 2003 an analogous, slightly expanded, questionnaire was sent to a random sample of men from the age cohorts 46, 51 years, etc. (n = 10,845). A total of 4072 men received both surveys, thereby constituting a group of men followed longitudinally for 11 years. The future risk of developing ED in the different age cohorts, adjusted for a number of ED risk factors, was then assessed. Results: A total of 3257 men responded to both questionnaires (response rate = 80%, age range = 56-103 years). The risk of having ED increased substantially with increasing age, both within each survey and longitudinally between the surveys. The adjusted risk of developing ED within the next 11 years increased with a factor of 10, from 1.8% at the age of 45 years at baseline to as much as 11.4% at the age of 65 years. Conclusion: Age as a risk-factor for ED is a non-linear function and should be adjusted as such to avoid bias when including men of different ages in interventional studies on ED.

Abstract
Introduction The importance of erectile dysfunction (ED) diagnosis and treatment has been highlighted since the early 2000s. However, nearly 20 years after the first phosphodiesterase 5 inhibitor (PDE5i) was marketed, underdiagnosis and undertreatment of ED in the primary health care setting may still be present. Aim To assess the relative frequency of patients who are medically treated for ED before referral to specialized urology care. The secondary objectives were to evaluate possible reasons for non-treatment prior to referral and other signs of undertreatment, namely cardiovascular risk assessment and antihypertensive treatment. Methods 200 male patients referred for ED to specialist urology care by general practitioners were screened after consent between January 2016–December 2018. A full standardized medical and sexual history were taken. Previous medical treatment of ED, namely pharmacologic name and dosages, and cardiovascular risk factors were noted. Main Outcome Measures Of the 115 included patients, only 33.9% of patients had already taken PDE5i before referral, and none had taken alprostadil by intracavernous route. Results The mean patient age was 58.68 ± 10.01 years old. Only 45.2% had been prescribed the highest dose of PD5i. From the remaining untreated patients, only 19.7% had ≥3 cardiovascular risk factors, including 5.6% of patients who also presented moderate-to-severe stable or unstable angina requiring a stress test or cardiology assessment before treatment. Regarding the 54 patients with medical history of arterial hypertension, 43.4% and 30.2% were treated for hypertension with a diuretic and a beta blocker, respectively. Conclusion More focus on the primary healthcare continuous medical education regarding sexual dysfunction, namely ED, is needed because major undertreatment of ED is still present because low prescription of PD5i before referral is noted.

Abstract
Erectile dysfunction has been described as a sentinel marker of co-existing and undetected cardiovascular disease. Beside cardiovascular diseases, a correlation between erectile dysfunction and other major comorbidities has been also reported. The study was aimed to analyze the association between sexual functioning and overall men's health in sexually active, Caucasian-European men with new-onset sexual dysfunction. Data from the last 881 consecutive patients seeking first medical help for sexual dysfunction were cross-sectionally analyzed. The International Classification of Diseases, 9th revision, Clinical Modification was used to classify health-significant comorbidities, which were scored with the Charlson Comorbidity Index (CCI). A modified CCI score from which all potential cardiovascular risk factors (CCI-CV) were subtracted was then calculated for every patient. Patients were requested to complete the International Index of Erectile Function (IIEF). The main outcome of the study was the association between the IIEF domain scores and CCI, which scored health-significant comorbidities even irrespective of cardiovascular risk factors (CCI-CV). The final sample included 757 patients (85.9%) (Median age: 48 years; IQ range: 37-59). Overall, erectile dysfunction was found in 540 (71.4%) patients. Of these, 164 (21.6%) had a CCI ≥ 1 and 138 (18.2%) had a CCI-CV ≥ 1, respectively. At the analysis of variance, IIEF-Erectile Function (EF) scores significantly decreased as a function of incremental CCI and CCI-CV scores (all p < 0.01). At multivariable logistic regression analysis, both IIEF-EF and IIEF-total score achieved independent predictor status for either CCI ≥ 1 or CCI-CV ≥ 1, after accounting for potential confounders (p < 0.01). We report novel findings of a significant association between erectile dysfunction severity and overall men's health, even irrespective of cardiovascular risk factors. Thereof, erectile dysfunction severity could serve as a proxy for general men's health, thus encouraging physicians to comprehensively assess patients complaining of sexual dysfunction in the real-life everyday clinical practice.

Abstract
It is well known that there is an association of lower urinary tract symptoms/benign prostatic hypertrophy with cardiovascular disease, suggesting that lower urinary tract symptoms/benign prostatic hypertrophy is a risk factor for cardiovascular events. Vascular function, including endothelial function and vascular smooth muscle function, is involved in the pathogenesis, maintenance and development of atherosclerosis, leading to cardiovascular events. Vascular dysfunction per se should also contribute to lower urinary tract symptoms/benign prostatic hypertrophy. Both lower urinary tract symptoms/benign prostatic hypertrophy and vascular dysfunction have cardiovascular risk factors, such as hypertension, dyslipidemia, diabetes mellitus, aging, obesity and smoking. Inactivation of the phosphodiesterase type 5-cyclic guanosine 3',5'-monophosphate-nitric oxide pathway causes lower urinary tract symptoms/benign prostatic hypertrophy through an enhancement of sympathetic nervous activity, endothelial dysfunction, increase in Rho-associated kinase activity and vasoconstriction, and decrease in blood flow of pelvic viscera. Both endogenous nitric oxide and exogenous nitric oxide act as vasodilators on vascular smooth muscle cells through an increase in the content of cyclic guanosine 3',5'-monophosphate, which is inactivated by phosphodiesterase type 5. In a clinical setting, phosphodiesterase type 5 inhibitors are widely used in patients with lower urinary tract symptoms/benign prostatic hypertrophy. Phosphodiesterase type 5 inhibitors might have beneficial effects on vascular function through not only inhibition of cyclic guanosine 3',5'-monophosphate degradation, but also increases in testosterone levels and nitric oxide bioavailability, increase in the number and improvement of the function of endothelial progenitor cells, and decrease in insulin resistance. In the present review, the relationships between lower urinary tract symptoms/benign prostatic hypertrophy, the phosphodiesterase type 5-nitric oxide-cyclic guanosine 3',5'-monophosphate pathway, vascular function and cardiovascular outcomes are examined.

[PMID: 28190453 PMCID: PMC5302379 DOI: 10.1016/j.esxm.2016.08.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2016] [Revised: 08/08/2016] [Accepted: 08/11/2016] [Indexed: 12/02/2022] Open
Abstract
Introduction Intracavernosal injection (ICI) therapy is widely used for the treatment of erectile dysfunction (ED). Its use in practice is largely empirical and has not been validated with evidence-based approaches. Aim To compare two strategies for ICI, specifically a risk-based approach and an empiric-based approach, and assess the efficacy, patient satisfaction, and complication rates of the two treatment approaches. Methods After obtaining approval from the institutional review board, a prospective database of patients enrolled in the ICI program at the Johns Hopkins Hospital (Baltimore, MD, USA) from May 2012 through May 2014 was amassed. Demographic information, treatment outcomes, and subjective patient evaluations of sexual function (International Index of Erectile Function erectile function domain [IIEF-EF], Quality of Erection Questionnaire [QEQ], Sexual Quality of Life [SQoL], and Erectile Dysfunction Inventory of Treatment Satisfaction [EDITS]) were obtained at baseline and at 3 and 6 months. Two approaches were compared. Group 1 received empiric ICI treatment initially with prostaglandin E1 (PGE1) 10 μg irrespective of ED etiology or severity. After initial dosing with PGE1 in the clinic, adjustments were made to titrate or change formulations pending on patient results. Group 2 received a risk-based approach, in which an algorithm that factored in ED etiology and number of ED risk factors was used for a bimix (papaverine 30 mg/mL, phentolamine 1 mg/mL), a low-dose trimix (papaverine 30 mg/mL, phentolamine 1 mg/mL, PGE1 10 μg/mL), or a high-dose trimix (papaverine 30 mg/mL, phentolamine 2 mg/mL, PGE1 40 μg/mL). Dose titration was permitted in the two groups. Statistical analysis was carried out using t-test and χ2 analysis. Main Outcome Measures The study design was powered for a non-inferiority comparison of the two approaches, in which the primary end point was a 15-point difference on the EDITS score or a 20% difference in the IIEF-EF score. Results One hundred seventy-five patients were enrolled (57 in group 1, 118 in group 2) with 3- and 6-month follow-up at 57% and 35%, respectively, and similar between groups. Baseline patient characteristics and sexual function questionnaire responses were similar between groups 1 and 2, although group 1 reported higher-quality erections at baseline (QEQ score = 14.3 vs 7.3, P = .05) and had a smaller proportion of patients with prostatectomy (54.4% vs 74.6%, P = .02). In the two groups, QEQ score (mean = 10.78 vs 56.76, P < .05), SQoL score (mean = 38.41 vs 50.25, P < .05), and IIEF-EF score (mean = 7.51 vs 18.48, P < .05) improved with treatment. However, at 3 and 6 months, there were no statistically significant differences in responses for IIEF, QEQ, SQoL, or EDITS scores and no difference in failure or medication switch rates between groups. There were no significant differences in complication rates, although at 3 months group 2 reported a higher incidence of priapism and pain (23% vs 7.4%, P = .08). Conclusion Empiric and risk-based strategies for ICI therapy resulted in significant improvements across multiple domains of sexual function. Complication rates, satisfaction, and efficacy overall were similar between the two approaches. Clinicians can be reassured that no one approach to ICI therapy for ED management appears inferior to another.

Abstract
Background Sexual difficulties (SD) are common among men of all ages and can have considerable impact on quality of life and indications for future health. SD are associated with mental and physical wellbeing and with relationship satisfaction, yet they are rarely discussed with medical professionals who are often ill equipped to assess and manage them. This paper provides an updated overview on the status of SD in Australian men from 18 to 55 years of age and will form a baseline comparison for future analyses of SD based on Ten to Men data. Methods We used data from Ten to Men, the Australian Longitudinal Study on Male Health. SD was measured using eight items capturing specific sexual difficulties. We examined associations of a range of health and lifestyle factors (smoking, alcohol consumption, illicit drug use, obesity and new sexual partners, self-rated health status, disability, pain medication, diagnosed physical and mental health conditions) with each SD using logistic regression. The sample included 12,636 adult males who had previously been sexually active. Analysis was stratified by age (18–34 years versus 35–55 years). Results This paper shows that experiencing SD is relatively common among Australian men – overall half the sample (54 %; 95 % CI: 0.53–0.55) experienced at least one SD for more than 3 months over the past 12 months. While more common in older men aged 45 to 55 years, almost half the 18 to 24 year old men (48 %) also reported at least one SD highlighting that SD affects men of all ages. We found that SDs were associated with both lifestyle and health factors, although the strongest associations were observed for health factors in both age groups, in particular poor self-rated health, having a disability and at least one mental health condition. Lifestyle factors associated with SDs in men of all ages included smoking, harmful alcohol consumption and drug use in the past 12 months. Obesity was only associated with an increased rate of SD in men aged 35 to 55 years. Conclusion Sexual difficulties are common among men of all ages and increasingly more prevalent as men grow older. They are strongly associated with both health and lifestyle factors. With previous literature showing that SDs can be a precursor of an underlying or developing physical and mental health condition, it is imperative that sexual health and sexual functioning is discussed with a doctor as part of a standard health check and across the lifespan.

Abstract
INTRODUCTION Erectile dysfunction (ED) has been significantly associated with many chronic conditions including obesity, the metabolic syndrome, hypogonadism, diabetes mellitus, cardiovascular disease (CVD), lower urinary tract symptoms, and psychiatric/psychological disorders. ED is also a well-established predictor of CVD. AIM This review will focus on the association of ED with cardiovascular, metabolic, and cognitive conditions and discuss the effects of managing lifestyle factors in order to reduce the burden of ED and consequently outcomes in patients with chronic conditions. METHODS A literature search using Medline, PubMed (U.S. National Library of Medicine and the National Institutes of Health), and abstracts from scientific meetings was performed from 1990. MAIN OUTCOME MEASURES Main outcome measures were improvements in sexual function. RESULTS A total of 59 reviews on the topic were evaluated. CONCLUSIONS Targeting several lifestyle factors associated with CVD/metabolic/cognitive disorders, e.g., smoking, alcohol consumption, obesity, and physical activity, can have significant benefits, leading to an improvement in ED as well as testosterone levels and consequently CVD.

Abstract
Introduction Oftentimes the older adults are assumed to be asexual as few studies explore into the sexuality of this age group worldwide and even in Nigeria. It is an important aspect of quality of life which is often neglected by people in this age group, attending physicians and the society as a whole. The study was aimed at determining the perception of older adults about sexuality, identify the factors that could militate against sexuality and fill any void in information in this regard. Methods Descriptive study conducted in one hundred older adults. A semi-structured questionnaire was administered to consenting participants between 1st of September 2013 and 31st of March 2014. Results Mean age of respondents was 66.42± 5.77 years. Seventy-eight percent of the male respondents considered engaging in sexual activity as safe compared to 45.8% of the female respondents. More of the women (33.3%) regarded sexuality in the older adults as a taboo when compared to the men (5.4%). However, the men were more favourably disposed to discussing sexual problems than the women with their spouses (42% vs 20%) and Physicians (23.2% vs 0.0%). Major factors responsible for sexual inactivity were participants’ medical ailments (65%), partners’ failing health (15%) as well as anxiety about sexual performance (25%) in the men and dyspareunia (25%) in women. Conclusion There is an urgent need to correct the misconception about sexuality in this age group especially among the women and for the physicians to explore the sexual history of every patient.
