The atherosclerotic cardiovascular disease risk score is a reliable tool to identify patients with arteriogenic erectile dysfunction.

BACKGROUND: The atherosclerotic cardiovascular disease risk score is a validated algorithm predicting an individual's 10-year risk of developing acute cardiovascular events (cardiovascular disease). Patients who suffer from arteriogenic erectile dysfunction are susceptible to developing cardiovascular disease in the future. OBJECTIVES: To apply the atherosclerotic cardiovascular disease score at a homogenous cohort of men with erectile dysfunction undergoing a dynamic penile colour Doppler duplex ultrasound and explore its predictive ability to identify patients with vasculogenic erectile dysfunction at colour Doppler duplex ultrasound. MATERIALS AND METHODS: Complete data of 219 patients undergoing colour Doppler duplex ultrasound were analysed. All patients completed the International Index of Erectile Function. The atherosclerotic cardiovascular disease score and Charlson comorbidity index were applied to the entire cohort. Patients were divided into those with normal vs. pathological parameters at colour Doppler duplex ultrasound. Descriptive statistics were used to explore differences between the two groups. Logistic regression models tested the potential role of atherosclerotic cardiovascular disease to predict arteriogenic and/or venogenic erectile dysfunction. Local polynomial smoothing models graphically displayed the probability of pathological colour Doppler duplex ultrasound parameters at different atherosclerotic cardiovascular disease scores. RESULTS: Overall, arteriogenic erectile dysfunction and venous leakage were diagnosed in 88 (40.2%) and 28 (12.8%) patients respectively. The median (interquartile range) atherosclerotic cardiovascular disease score was 7.7 (3.9-14). Patients with pathologic colour Doppler duplex ultrasound were older (59 vs. 54 years, p < 0.001), had higher Body Mass Index (26.5 vs. 25.6 kg/m2 , p = 0.04), more comorbidities (Charlson comorbidity index ≥ 1) (76.5% vs. 54.4%, p = 0.002) and higher median atherosclerotic cardiovascular disease scores (9.95 vs. 7, p = 0.005), respectively. At logistic regression analysis, a higher atherosclerotic cardiovascular disease risk score was independently associated with arteriogenic erectile dysfunction at colour Doppler duplex ultrasound (odds ratio: 1.03, 95% confidence interval: 1.01-1.08, p = 0.02) after adjusting for Body Mass Index, physical activity, alcohol consumption and severe erectile dysfunction. DISCUSSION: As vasculogenic erectile dysfunction may precede by some years the onset of acute cardiovascular diseases, the rigorous identification of patients with deficient cavernosal arterial blood flow, would definitely allow the implementation of earlier and more effective cardiovascular prevention strategies in men with erectile dysfunction. CONCLUSIONS: The atherosclerotic cardiovascular disease risk score represents a reliable tool to identify patients with arteriogenic erectile dysfunction in everyday clinical practice.

Erectile Dysfunction in Peripheral Vascular Disease: Endovascular Revascularization as a Potential Therapeutic Target.

INTRODUCTION: Erectile dysfunction (ED) affects more than 150 million men worldwide, with deleterious effects on quality of life. ED is known to be associated with ischemic heart disease but the impact of ED in patients with peripheral arterial disease (PAD) is unknown. We assessed the prevalence and severity of ED in patients with PVD. METHODS: Following ethical approval, sequential male patients diagnosed with PAD over a 1-year period following diagnosis of intermittent claudication. The patient demographics and comorbidities were recorded, with the International Index of Erectile Function (IIEF-5) questionnaire used to grade severity of ED. Computed tomographic angiography and severity of stenosis in the proximal vessels and internal pudendal arteries were correlated using a modified Bollinger Matrix scoring system. RESULTS: 60 patients were recruited, most (77.2%) reported erectile dysfunction (52.5% severe, 22.5% moderate). Patients with severe ED were more likely to have 2 or more comorbidities (P = .009). 86.7% with severe ED had bilateral internal pudendal artery stenosis with a mean modified Bollinger score of 17.6. 35.5% of moderate ED patients had bilateral internal pudendal stenosis with a mean Bollinger score of 11.75. There was significant difference in overall scores between moderate and severe erectile dysfunction (p< 0.05), thus indicating a potential link between ED severity and extent of vessel stenosis. CONCLUSION: There is a substantial burden of clinically significant ED among patients with PAD. This study suggests ED should be discussed with all PAD patients and ED may precede a PAD diagnosis. There is scope for endovascular revascularization as a treatment option for ED secondary to arterial insufficiency.

Update of the position paper on arterial hypertension and erectile dysfunction.

: Sexual health is an integral part of overall health, and an active and healthy sexual life is an essential aspect of a good life quality. Cardiovascular disease and sexual health share common risk factors (arterial hypertension, diabetes mellitus, dyslipidemia, obesity, and smoking) and common mediating mechanisms (endothelial dysfunction, subclinical inflammation, and atherosclerosis). This generated a shift of thinking about the pathophysiology and subsequently the management of sexual dysfunction. The introduction of phosphodiesterase type 5 inhibitors revolutionized the management of sexual dysfunction in men. This article will focus on erectile dysfunction and its association with arterial hypertension. This update of the position paper was created by the Working Group on Sexual Dysfunction and Arterial Hypertension of the European Society of Hypertension. This working group has been very active during the last years in promoting the familiarization of hypertension specialists and related physicians with erectile dysfunction, through numerous lectures in national and international meetings, a position paper, newsletters, guidelines, and a book specifically addressing erectile dysfunction in hypertensive patients. It was noted that erectile dysfunction precedes the development of coronary artery disease. The artery size hypothesis has been proposed as a potential explanation for this observation. This hypothesis seeks to explain the differing manifestation of the same vascular condition, based on the size of the vessels. Clinical presentations of the atherosclerotic and/or endothelium disease in the penile arteries might precede the corresponding manifestations from larger arteries. Treated hypertensive patients are more likely to have sexual dysfunction compared with untreated ones, suggesting a detrimental role of antihypertensive treatment on erectile function. The occurrence of erectile dysfunction seems to be related to undesirable effects of antihypertensive drugs on the penile tissue. Available information points toward divergent effects of antihypertensive drugs on erectile function, with diuretics and beta-blockers possessing the worst profile and angiotensin receptor blockers and nebivolol the best profile.

Erectile dysfunction links to cardiovascular disease-defining the clinical value.

Despite many advances over the last few decades, cardiovascular disease (CVD) remains the leading cause of death globally, with men afflicted at an earlier age than women. In a bid to reduce the global burden of morbidity and mortality due to CVD, emphasis has been placed on prevention, particularly on widespread promotion of ideal cardiovascular health behaviors and advancing strategies to identify and treat high-risk individuals who may benefit from aggressive preventive therapy. Erectile dysfunction is a highly prevalent condition that has been demonstrated to share the same risk factors as clinical CVD, and to have independent predictive value for future CVD events. Importantly, subclinical atherosclerosis appears to precede vascular ED by a decade or longer, with ED preceding clinical CVD such as myocardial infarction and stroke in temporal sequence by about 2-5 years. Crucially, since ED may represent the first presentation of otherwise "healthy" men to care providers, a clinical diagnosis of vascular ED may represent a unique opportunity to identify high risk individuals, intervene, and thus prevent progression to clinical CVD. This review summarizes up-to-date evidence of the relationship between ED and subclinical and clinical CVD, and details the position of current guidelines and clinical recommendations on the role of ED assessment in CVD prevention. Finally, this review proposes a clinical framework for the incorporation of ED into standard CVD risk assessment in middle-age men.

Erectile dysfunction - overview from a cardiovascular perspective.

Erectile dysfunction (ED) is an evolving health problem with growing incidence in the ageing male population with potentially predictive value for cardiovascular and other chronic diseases. ED shares the common cardiovascular risk factors. The aetiology of ED is numerous including neurogenic, psychogenic, arteriogenic, and venogenic reasons. The origin of arteriogenic ED is frequently atherosclerosis. Patients not adequately responding to conservative measures including oral medication are often referred to further vascular diagnostics and therapy. At present, the refinements in endovascular therapy allow for minimal-invasive revascularization of erection-related arteries. The role of endovascular therapy in the complex framework of the multifactorial causes of ED requires further scientific scrutiny.

[Lower urinary tract symptoms related to benign prostatic hyperplasia and erectile dysfunction: A systematic review]. / Symptômes du bas appareil urinaire secondaire à une hyperplasie bénigne de prostate et dysfonction érectile : une revue systématique de la littérature.

AIM: To provide a systematic review of epidemiological data regarding the association between erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) in men. SEARCH STRATEGY: A research has been conducted on the Medline database using the keywords: ("erectile dysfunction" or "sexual dysfunction") and ("benign prostatic hyperplasia" or "lower urinary tract symptoms"). The eligibility of studies was defined using the PICOS method in accordance with the PRISMA statement. Cross-sectional studies and prospective cohorts assessing the association between LUTS and ED in the primary care setting or in general practice (i.e. exclusion of patients seen in outpatient urology or andrology) were included. RESULTS: Among 898 reports assessed, seven studies were included in this systematic review (whole cohort: 1,196,393 men). There were five cross-sectional studies and two prospective cohorts. The whole seven studies reported an association between LUTS and ED (range of odds-ratio: 1.52-4.03). Four common pathogenic mechanisms were found in the literature, all of them being somewhat related with metabolic syndrome and cardiovascular risk factors: reduced nitric oxide (NO) pathway signalling, increased RhoA-Rho kinase signalling, autonomic nervous system hyperactivity and pelvic atherosclerosis. LIMITATIONS: The main limitations of this review were: a possible publication bias, the relatively low number of included studies and the lack of assessment of potential confounders such as factors related to sexual partner. CONCLUSION: The close epidemiological and pathogenic links between LUTS and ED have given rise to a new nosological entity: the erectile urogenital dysfunction, which should be assessed globally with special considerations to frequently associated comorbidities such as metabolic syndrome and cardiovascular risk factors.

Erectile dysfunction as a predictor of advanced vascular age.

Vascular age (VA) represents chronological age (CA) adjusted for individual's atherosclerotic burden. The presence of erectile dysfunction (ED) has been considered as a clinical sentinel of premature atherosclerosis. The objective of this study was to explore the predictive value of ED in assessing the discrepancy between VA and CA. In the period from 1 January 2014 to 1 January 2015, all consecutive men referring to the outpatient departments of the Clinics of Urology and Cardiology in Belgrade (Serbia) were considered for enrolment in this cross-sectional study. General exclusion criteria were: age below 18, heart failure, history of myocardial infarction, impaired renal and liver function, acute infection, history of endocrine disease other than type 2 diabetes, pelvic surgery or trauma, and acute coronary syndrome within the last 6 months. According to the presence of ED, hypertension, type 2 diabetes and history of coronary artery disease participants were assigned into five study groups. Hierarchical multiple regression analysis was conducted to identify the predictive value of ED in detection of advanced VA. The mean age of males enrolled in the study was 52.9 ± 7.7 years. The predominance of VA over CA was statistically significantly higher in the group of participants with coexistence of ED and hypertension compared to the group of patients with ED and type 2 diabetes (p = 0.027) and the group of patients with ED (p = 0.014) and control group (p < 0.01). Regression analysis highlighted that ED represented a highly important marker (p < 0.01) of advanced VA, which independently accounted for 6.1% of the variance in the discrepancy between VA and CA. Our study suggests that assessment of ED could be a part of a more comprehensive prediction of patients' advanced VA. Screening among such a highly selected population may help identify those that would most benefit from drug treatments and life style changes.

Erectile dysfunction post-perineal anastomotic urethroplasty for traumatic urethral injuries: analysis of incidence and possibility of recovery.

PURPOSE: To evaluate the incidence of erectile dysfunction (ED) and recoverability of erectile function (EF) after anastomotic urethroplasty for traumatic urethral injuries (TUIs) of different etiologies. METHODS: A retrospective review for patients' records underwent perineal anastomotic urethroplasty for TUIs from June 1998 to January 2014 was conducted. Those patients were contacted and evaluated using the International Index of erectile function questionnaire in sexually active men, and in unmarried men, the single-question self-report of ED was used. Patients with ED underwent penile color Doppler ultrasonography. RESULTS: Overall, 81 patients were included in the study. The incidences of ED following urethroplasty for TUIs were 72.3, 35.3 and 0% in cases due to pelvic fracture, straddle and iatrogenic injuries, respectively. None of the patients reported deterioration of EF after urethroplasty. Seven (13.5%) patients reported recovery of their EF within 2 years after trauma. The probability of recovery of EF after PFUI was 9% compared to 28.6 and 100% in patients with straddle and iatrogenic urethral injuries, respectively. Patients with type C pelvic fracture had no chance for EF recoverability. CONCLUSIONS: PFUIs have a probability of causing ED as much as 72% compared to 35 and 0% in men with straddle and iatrogenic urethral injuries, respectively. Anastomotic urethroplasty has no deleterious effect on EF. A tendency for higher recoverability of EF could be observed after iatrogenic urethral injuries followed by straddle injury then PFUIs. The probability of recovery decreased proportionally with severity of pelvic trauma.

Cardiovascular disease and male sexual dysfunction.

Erectile dysfunction (ED) is a form of sexual dysfunction that is estimated to affect > 30% of men between the ages of 40 and 70. As a result of an improved understanding about the pathophysiology of ED and improved treatment options, an increasing number of men are presenting for evaluation than several decades ago. In fact, many of these men are visiting their health care professional for the first time with ED as their primary complaint. Most of these men are unaware of the link between ED and cardiovascular disease (CVD).

Clinical correlates of enlarged prostate size in subjects with sexual dysfunction.

Digito-rectal examination (DRE) of the prostate provides useful information on the state of prostate growth and on the presence of suspected peripheral nodules. The aim of this study is to describe the clinical and biochemical correlates of finding an enlarged prostate size at DRE in subjects with sexual dysfunction (SD). A consecutive series of 2379 patients was retrospectively studied. The analysis was focused on a subset of subjects (n = 1823; mean age 54.7 ± 11.4) selected for being free from overt prostatic diseases. Several parameters were investigated. After adjusting for confounders, the presence of an enlarged prostate size at DRE was associated with a higher risk of metabolic syndrome (HR = 1.346 (1.129-1.759); P = 0.030), type 2 diabetes mellitus (HR = 1.489 (1.120-1.980); P = 0.006), increased LDL cholesterol (>100 mg dl-1 ; HR = 1.354 (1.018-1.801); P = 0.037) and increased mean blood pressure (BP) values (HR = 1.017 (1.007-1.027) for each mmHg increment; P = 0.001). Accordingly, enlarged prostate size was also associated with a higher risk of arteriogenic erectile dysfunction (ED), as well as with other andrological conditions, such as varicocele and premature ejaculation (PE). PSA levels were significantly higher in subjects with enlarged prostate size when compared to the rest of the sample (HR = 3.318 (2.304; 4.799) for each log unit increment in PSA levels; P < 0.0001). Arteriogenic ED, according to different criteria, was also associated with increased PSA levels. In conclusion, our data support the need to examine prostate size either by clinical (DRE) or biochemical (PSA) inspection in subjects with SD, in order to have insights into the nature of the SD and the metabolic and cardiovascular (CV) background of the patient.

Deformity stabilization and improvement in men with untreated Peyronie's disease.

OBJECTIVE: To define predictors of the deformity stabilisation and improvement in men with untreated Peyronie's disease (PD). PATIENTS AND METHODS: The study population consisted of patients with PD-associated uniplanar curvature, who opted for no treatment and were followed for at least 12 months. All patients had deformity assessment (DA) performed on initial presentation and at follow-up. Stabilisation of PD was defined as no change between DAs (±10°), while improvement and progression were defined as ≥10° change. Patients were subdivided into different groups based on time to presentation: ≤6 months (A), 7-12 months (B), and 13-18 months (C). Multivariable analysis was used to define predictors of stabilisation and improvement. RESULTS: In all, 176 men met the inclusion criteria. The mean age was 54 years, with a mean (sd) PD duration of 9 (12) months and mean curvature of 42 (27)°. In all, 67% of the entire population had no change in deformity over time, 12% improved with a mean (sd) change of 27 (14)°, and 21% worsened with a mean (sd) change of 22 (11)°. On multivariate analysis, predictors of stabilisation included: time to presentation of >6 months (odds ratio [OR] 2.4, P < 0.01), per decade increase in age (OR 1.5, P < 0.05), and age (r = 0.32, P < 0.05). Predictors of improvement included: time to presentation of ≤6 months (OR 4.1, P < 0.001), and per decade decrease in age (OR 2.1, P < 0.01). CONCLUSIONS: In men with uniplanar curvature, PD stabilisation and improvement rates change with time-to-presentation and patient age. These data may aid in counselling patients with PD.

Erectile dysfunction, penile atherosclerosis, and coronary artery vasculopathy in heart transplant recipients.

INTRODUCTION: Vascular erectile dysfunction (ED) is the expression of a systemic vascular disease and in particular of endothelial dysfunction. Dysfunctional endothelium plays also a significant role in the onset and progression of coronary artery vasculopathy (CAV). AIM: This pilot study was designed to evaluate the prevalence and pathogenesis of ED and its correlation with CAV in heart transplanted male. METHODS: A total of 77 male heart transplanted patients (HTx) evaluated in our center (mean age 61.6 + 10.6 years) were enrolled in the study. MAIN OUTCOME MEASURES: All subjects underwent accurate medical history collection, including lifestyle (cigarette smoking, dietary and sedentary habits, drug intake, and erectile function before cardiac transplantation), physical examination (body mass index and arterial pressure), biochemical blood tests (fasting glucose, total cholesterol, high-density lipoprotein cholesterol, and triglycerides), and hormones (prolactin, luteinizing hormone and total testosterone). Furthermore, they were studied with penile, carotid, femoral echo-color Doppler ultrasonography and coronary angiogram. RESULTS: Incidence of ED was 24% before HTx and increased up to 65% after. Postischemic cardiomiopathy was an indication to HTx in ED group more frequently than in patients without ED (No-ED group) (45.1% vs. 20%). ED patients showed a lower peak systolic velocity, a higher cavernosal intima-media thickness (IMT), a higher prevalence of cavernosal plaques (26.7% vs. 5.2%, P < 0.05), peripheral vascular disease (60.87% vs. 26.1%, P < 0.05) and CAV (45.8% vs. 25.8%, P < 0.05) with respect to No-ED patients. Coronary flow reserve was significantly reduced in ED vs. No-ED patients (2.43 + 0.7 vs. 2.9 + 0.8, P < 0.04). Finally, cavernous plaque and testosterone plasma levels were statistically associated with CAV. CONCLUSIONS: We showed that ED is a frequent disease in HTx patients, more common when the original pathology is postischemic cardiomiopathy and associated with higher prevalence of cavernous plaques and CAV. Its evaluation should be integral to an HTx rehab program.

[Men with type 2 diabetes and erectile dysfunction are a particular risk group for LUTS - results of the Witten Diabetes Survey]. / Männer mit Typ-2-Diabetes und Erektiler Dysfunktion sind eine besondere Risikogruppe für LUTS - Ergebnisse der Wittener Diabetes-Erhebung.

INTRODUCTION: According to our data on 4 071 patients with type 2 diabetes, 65.5% of the men and 70.4% of the women complain of lower urinary tract symptoms (LUTS). That is twice as much as the normal population for the same age group. The most common symptom was overactive bladder (OAB). In patients with a diabetes-related complication such as retinopathy or nephropathy, the incidence for LUTS was about 20% higher than that in patients without complications, whereas in men with diabetes mellitus type 2 and erectile dysfunction (ED) the incidence for LUTS was 31.9% higher than without ED. We wanted to compare the incidence of LUTS in patients with type 2 diabetes and ED against patients without ED as well as women with type 2 diabetes. RESULTS: Men with ED had a statistically significant longer history of diabetes, a higher HbA1c and increased serum creatinine compared to men without ED (p value <0.0001). The length of diabetes history was not statistically relevant compared to women with type 2 diabetes. However the HbA1c and serum creatinine were higher than those of the women from the data bank (p value <0.0001). Diabetic men with ED complained more often of urinary incontinence, urge incontinence and made more often use of incontinence pads (p value <0.0001). As for pollakisuria and nocturia the difference was not significant. 42.3% of type 2 diabetic patients with ED were diagnosed with OAB by their urologist or GP. That was significantly more than type 2 diabetic patients without ED and type 2 diabetic women (see graph). The same was true of stress incontinence, overflow incontinence and non-classified incontinence with the exception of faecal incontinence. Patients with type 2 diabetes and ED had to take drugs more often than type 2 diabetic men without ED and women with diabetes. CONCLUSION: Amongst patients with type 2 diabetes, ED increases the risk of developing lower urinary tract disorders. Moreover it is connected with a higher HbA1c and a higher risk for LUTS, especially for OAB. The regular use of incontinence pads in every fourth patient with type 2 diabetes and erectile dysfunction demonstrates a high number of under-treated patients. Patients with type 2 diabetes and especially patients with type 2 diabetes AND erectile dysfunction represent a risk group that needs special attention and a special management plan from urologists and GPs.

Early onset erectile dysfunction is usually not associated with abnormal cavernosal arterial Inflow.

Endothelial dysfunction, a marker for atherosclerosis and hence arterial disease, has recently been proffered as the main offender within the vascular system to predict not only the future onset of erectile dysfunction (ED) but also as the main cause of the ED. To glean more insight into whether arterial disease is indeed operative during the early onset of ED, we reviewed the duplex ultrasound scans of 23 men with ED who were younger than 50 years of age. Depending on the criteria used for abnormal arterial responses, it was determined in this cohort of young men that there was only a 4-13% incidence of abnormal arterial responses. These observations suggest that the penile arterial system does not appear to be primarily involved in the etiology of the majority cases of ED that occur in young men.

Penile alterations with severe sperm abnormalities in antiphospholipid syndrome associated with systemic lupus erythematosus.

This study aims to perform global gonadal and sexual function assessments in systemic lupus erythematosus-related antiphospholipid syndrome (SLE-APS) patients. A cross-sectional study was conducted in ten SLE-APS male patients and 20 healthy controls. They were assessed by demographic data, clinical features, urological examination, sexual function, testicular ultrasound, seminal parameters, sperm antibodies, and hormone profile. The median of current age was similar in SLE-APS patients and controls with a higher frequency of erectile dysfunction in the former group (30 vs. 0 %, p = 0.029). The median penis circumference was significantly reduced in SLE-APS patients with erectile dysfunction compared to patients without this complication (8.17 vs. 9.14 cm, p = 0.0397). SLE-APS patients with previous arterial thrombosis had a significantly reduced median penis circumference compared to those without this complication (7.5 vs. 9.18 cm, p = 0.039). Comparing SLE-APS patients and controls, the former had a significant lower median of sperm concentration (41.1 vs. 120.06 × 10(6)/mL, p = 0.003), percentages of sperm motility (47.25 vs. 65.42 %, p = 0.047), normal sperm forms by WHO guidelines (11 vs. 23.95 %, p = 0.002), and Kruger criteria (2.65 vs. 7.65 %, p = 0.02). Regarding seminal analysis, the medians of sperm concentration and total sperm count were significantly lower in SLE-APS patients treated with intravenous cyclophosphamide vs. those untreated with this drug (p < 0.05). Therefore, we have observed a novel association of reduced penile size with erectile dysfunction and previous arterial thrombosis in SLE-APS patients. Penis assessment should be routinely done in SLE-APS patients with fertility problems. We also identified that intravenous cyclophosphamide underlies severe sperm alterations in these patients.

How to identify subjects with poly-vascular disease?

Multisite artery or polyvascular disease is common. In the REACH registry, 15.9% of patients with either established atherosclerotic arterial disease or at least 3 risk factors for atherothrombosis had symptomatic polyvascular disease. History of risk factors and known co-morbidities, as well as a thorough physical examination, are mandatory in the initial screening and diagnostic work-up. Various non-invasive imaging techniques (duplex ultrasound, computed tomography angiography, magnetic resonance angiography) can be used for the identification of the polyvascular patient. Digital subtraction angiography is now used almost exclusively in association with endovascular procedures. Appropriate implementation of each technique is based on international guidelines and a multidisciplinary discussion for each case. The presence of co-existing disease in a different vascular bed is associated with a higher risk of recurrent symptoms and complications in the first site. In this context, accumulating evidence suggests that arterial biomarkers, such as arterial stiffness (pulse wave velocity), central blood pressures, wave reflections indices, ankle-brachial index, carotid intimamedia thickness, as well as vasculogenic erectile dysfunction, can predict cardiovascular morbidity and mortality beyond classical risk factors and prediction models. An important pending question is whether identification of multisite arterial disease may improve clinical outcomes in patients who are already in secondary prevention programs. Such screening of asymptomatic multisite artery disease in patients with known CVD would be of paramount importance if it is ultimately proven with hard evidence that it should lead to a different management from the one proposed for CVD patients without multisite artery disease.

Metabolic and cardiovascular outcomes of fatherhood: results from a cohort of study in subjects with sexual dysfunction.

INTRODUCTION: Previous cross-sectional and longitudinal studies reported a negative correlation between fatherhood and testosterone (T) levels, likely due to a centrally mediated downregulation of the hypothalamic-pituitary-gonadal axis. Moreover, epidemiological data indicate that fatherhood might affect metabolic and cardiovascular outcomes, although different results have been reported. Up to now, no studies have evaluated these associations in a population of men seeking treatment for sexual dysfunction (SD). AIM: To explore biological and clinical correlates of number of children (NoC) and its possible associations with forthcoming major cardiovascular events (MACE) in a sample of men with SD. METHODS: A consecutive series of 4,045 subjects (mean age 52 ± 13.1 years old) attending the Outpatient Clinic for SD was retrospectively studied. A subset of the previous sample (N = 1,687) was enrolled in a longitudinal study. MAIN OUTCOME MEASURES: Information on MACE was obtained through the City of Florence Registry Office. RESULTS: Among patients studied, 31.6% had no children, while 26.3% reported having one child, 33.4% two, and 8.8% three or more children. Although fatherhood was negatively related with follicle-stimulating hormone levels and positively with testis volume, we found a NoC-dependent, stepwise decrease in T plasma levels, not compensated by a concomitant increase in luteinizing hormone. NoC was associated with a worse metabolic and cardiovascular profile, as well as worse penile blood flows and a higher prevalence of metabolic syndrome (MetS). In the longitudinal study, after adjusting for confounders, NoC was independently associated with a higher incidence of MACE. However, when the presence of MetS was introduced as a further covariate, the association was no longer significant. CONCLUSIONS: This study supports the hypothesis that bond maintenance contexts and fatherhood are associated with an adaptive downregulation of the gonadotropin-gonadal axis, even in a sample of men with SD. Moreover, our data suggest that NoC predicts MACE, most likely because of an unfavorable, lifestyle-dependent, parenthood-associated behavior.
