Yu Z, Niu J, Wang C. The Prevalence and Risk Factors of Sexual Dysfunction in the Elderly in Southern China. Int J Gen Med 2024; 17:2355-2360. [PMID: 38803552 PMCID: PMC11128761 DOI: 10.2147/ijgm.s462124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 05/01/2024] [Indexed: 05/29/2024] Open
Abstract
Objective This study aims to evaluate the epidemiological features of sexual dysfunction in people aged more than 65 years in parts of China, and to investigate the independent significant risk factors. Methods According to the population distribution of five communities in Xiamen and Chongqing, we have randomly enrolled 2403 people more than 65 years-of-age. We collected data information through a questionnaire survey. Then demonstrated the current condition of sexual dysfunction in the samples by statistical analysis, and multivariable logistic regression was used to disclose the risk factors of sexual dysfunction in the older adults. Results According to this study, about 10.48% of the elderly had sexual dysfunctions of different degrees and duration. The proportion of men was about twice that of women (14.5% of males and 7.3% of females). During the course of the disease, 3.19% (43/1344) of women and 3.31% (35/1059) of men had more than 15 years duration of sexual dysfunction. In severity, 5.7% (77/1344) of women and 7.0% (74/1059) of men had very severe sexual dysfunction. There were statistically significant differences in BMI, smoking, drinking history, hypertension, depression incidence or median (p<0.05). Alcohol consumption history [OR = 1.711, 95% CI: 1.124-2.604, p = 0.012] and depression [OR = 2.107, 95% CI: 1.109-4.356, p =0.044] were independent risk factors for sexual dysfunction. Conclusion The prevalence of sexual dysfunction was low among elderly in the southern part of China. But the course of the disease is long and the degree of the disease is very severe. Elderly with a history of drinking and depression are more prone to sexual dysfunction.

Hu Z, Chen K, Dai H, Lv Z, Li J, Yu P, Feng J, Abdulkarem AM, Wu H, He R, Li G. ROUX-en-Y gastric bypass surgery improves metabolic syndrome-related erectile dysfunction in mice via the IRS-1/PI3K/AKT/eNOS pathway. Sex Med 2024; 12:qfae029. [PMID: 38817951 PMCID: PMC11134102 DOI: 10.1093/sexmed/qfae029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 04/10/2024] [Accepted: 05/05/2024] [Indexed: 06/01/2024] Open
Abstract
Objective Although many clinical studies have shown that ROUX-en-Y gastric bypass (RYGB) surgery significantly improves metabolic syndrome-related erectile dysfunction (MED), the role and mechanism are unclear. Aim In this study we used a mouse model to explore how RYGB improves MED induced by a high-fat diet (HFD). Methods We established a mouse model of metabolic syndrome by feeding an HFD for 16 weeks. The mice were randomly assigned to the standard chow diet (SCD), HFD, or RYGB groups. Body weight, fasting blood glucose, plasma insulin, and total plasma cholesterol were analyzed. Erectile responses were evaluated by determining the mean systolic blood pressure and the intracavernosal pressure (ICP). Penile histologic examination (Masson's trichrome and immunohistochemical stain) and Western blot were performed. Result Compared with the SCD group, the ICP in the sham group was significantly lower, and the ICP of the RYGB was significantly increased. Masson's trichrome and immunohistochemical staining showed that the content of endothelium and smooth muscle in the corpus cavernosum of mice with MED was significantly reduced. Western blot analysis showed a significant decrease in α-smooth muscle actin and a significant increase in osteopontin in penile tissue in the sham group, which was improved by RYGB surgery. Furthermore, RYGB significantly increased IRS-1/PI3K/Akt/eNOS phosphorylation. Clinical Translation In this study we explored the mechanism of bariatric surgery to improve erectile dysfunction associated with metabolic syndrome and provided a theoretical basis for clinical research. Strengths and Limitations First, we did not investigate the mechanism by which RYGB affects the IRS-1/PI3K/Akt/eNOS signaling pathway. Second, the effect of the IRS-1/PI3K/Akt/eNOS signaling pathway on the function of corpus cavernosum endothelial cells and smooth muscle cells remains to be investigated in cellular studies. Conclusion This study demonstrated that RYGB may not only improve metabolic parameters but also restore erectile function in MED patients. The mechanism of the therapeutic effect of RYGB may be reactivation of the IRS-1/PI3K/Akt/eNOS pathway.

Abstract
BACKGROUND Erectile dysfunction (ED) is closely associated with dyslipidemia; however, it is yet unknown how ED and remnant cholesterol (RC) are related. As such, this research sought to explore the correlation between RC and ED among individuals with diagnosed with diabetes. METHODS This cross-sectional study used information from 215 males from National Health and Nutrition Examination Survey (NHANES) from 2001 to 2004. RC was calculated as follows: the values of high-density lipoprotein cholesterol (HDL-c) and low-density lipoprotein cholesterol (LDL-c) were subtracted from the total cholesterol (TC) value, while ED diagnoses were based on self-reports. Weighted logistic regression analyses using both univariate and multivariate approaches were conducted to assess the correlation between RC and ED. RESULTS After comprehensive adjustment, multivariable logistic regression models revealed a strong correlation between RC and ED in subjects with diabetes (with an odds ratio (OR) of 7.49 and a 95% confidence interval (CI) of 1.98-28.37; P = 0.004). On categorizing RC into 3 grades (T1-T3), the OR corresponding to higher RC grade increased. Despite the results not reaching statistical significance upon categorization, a consistent and statistically significant trend (P for trend < 0.05) was observed. CONCLUSION This study indicated a correlation between increased RC levels and a higher prevalence of ED in diabetic males. RC may serve as a promising predictor of ED in individuals with diabetes. However, additional studies are required to confirm these findings.

Abstract
Objective To assess the causal effect of type 2 diabetes mellitus (T2DM) on male infertility (MI) and erectile dysfunction (ED) by Mendelian randomization (MR) analysis. Methods Data for T2DM, MI, and ED were obtained from genome-wide association studies (GWAS) involving 298, 957, 73, 479, and 223, 805 Europeans, respectively. We performed univariate MR analysis using MR Egger, Weighted median (WM) and Inverse variance weighted (IVW) methods to assess causal effects among the three. Through the Genotype Tissue Expression (GTEx) database, single-nucleotide polymorphisms (SNPs) that affect the expression levels of T2DM-related genes were located using expression quantitative trait loci (eQTL). Results MR analysis showed a significant causal relationship between T2DM and ED (WM, OR: 1.180, 95%CI: 1.010-1.378, P = 0.037; IVW, OR: 1.190, 95%CI: 1.084-1.300, P < 0.001). There is also a significant causal relationship between T2DM and MI (MR Egger, OR: 0.549, 95%CI: 0.317-0.952, P = 0.037; WM, OR: 0.593, 95%CI: 0.400, P = 0.010; IVW, OR: 0.767, 95%CI: 0.600-0.980, P = 0.034). ED may not cause MI (P > 0.05). We also found that rs6585827 corresponding to the PLEKHA1 gene associated with T2DM is an eQTL variant affecting the expression of this gene. Conclusion T2DM has a direct causal effect on ED and MI. The level of PLEKHA1 expression suppressed by rs6585827 is potentially associated with a lower risk of T2DM.

Abstract
Erectile dysfunction (ED) is the most common sexual dysfunction disease in adult males. ED can be caused by many factors, such as vascular disease, neuropathy, metabolic disturbances, psychosocial causes, and side effects of medications. Although current oral phosphodiesterase type 5 inhibitors can achieve a certain effect, they cause temporary dilatation of blood vessels with no curative treatment effects. Emerging targeted technologies, such as stem cell therapy, protein therapy, and low-intensity extracorporeal shock wave therapy (Li-ESWT), are being used to achieve more natural and long-lasting effects in treating ED. However, the development and application of these therapeutic methods are still in their infancy, and their pharmacological pathways and specific mechanisms have not been fully discovered. This article reviews the preclinical basic research progress of stem cells, proteins, and Li-ESWT therapy, as well as the current status of clinical application of Li-ESWT therapy.

Abstract
The Mediterranean diet (MD) has been previously proven to have various health-related benefits; however, its effect on women's reproductive health over a lifespan is yet to be summarized. This study aimed to summarize the evidence-based knowledge regarding the association between the MD and selected reproductive health outcomes. By searching PubMed, ScienceDirect, and Google Scholar databases, as well as reference lists, 21 studies were included in this narrative review. The available evidence was very limited; however, there is some suggestion that higher adherence to the MD may be positively associated with a lower risk of early age menarche (1 study) and shorter menstrual cycles (1 study), but is unrelated to dysmenorrhea (1 study). Moreover, no study to date has examined the relationship between the MD and the onset age of natural menopause. Considering reproductive health diseases, there was limited evidence that a higher adherence to the MD was associated with a lower risk of premenstrual syndrome (1 study), an improvement in sexual health and a lower prevalence of sexual dysfunction (3 studies), and an improvement in the general condition of with endometriosis and the pain they can experience (1 study). The largest number of studies were found for polycystic ovarian syndrome (PCOS; 7 studies) and infertility (6 studies). Results showed that a higher adherence to the MD was associated with a lower risk of infertility, while results for PCOS were unclear, but mostly indicated a beneficial trend. Further investigations are necessary to establish the role of adherence to the MD in reproductive health maintenance and its possible role in the prevention and treatment of reproductive health diseases in women.

Abstract
Sexual health communication is an important feature of healthy intimate relationships; however, some couples may avoid discussing difficult matters (e.g., HIV/STI testing, sexual satisfaction) to minimize interpersonal conflict. From October 2018 to May 2019 in New York State, we conducted a multi-method descriptive pilot study to characterize Black heterosexual couples' (N = 28) sexual health conversations. Partners individually completed an online sexual health/relationship survey before engaging in-person for a joint dyadic qualitative in-depth interview. Quantitative descriptive statistics demonstrated that most absolute score differences among couple's preferences for sexual health outcomes, communal coping and sexual relationship power were mainly small, but greatest regarding extra-dyadic sexual behaviors. A qualitative descriptive approach discerned, motivation and norms for sexual health conversations, and communication patterns. Thematic and content analysis revealed two central themes: initiating and sustaining sexual health conversations, and leveraging features of the couples to promote sexual health. Integrated findings indicate that couples possess varied communication patterns that operate with motivations for sexual health conversations toward subsequent sexual health promotion. Equitable and skewed communication patterns emerged as relationship assets that can be leveraged to optimize sexual health. There is also opportunity for future work to address communication regarding extra-dyadic behavior and preferences. Asset-based considerations are discussed.

Abstract
We aimed to examine the association between macronutrient and fatty acid intake and metabolic syndrome (MetS) and its components in South African male mini-bus taxi drivers. One hundred and eighty-five (n = 185) male taxi drivers, aged 20 years and older, who operate in the Cape Town metropole, South Africa, were included. The International Diabetes Federation (IDF) algorithm was used to define MetS. The association between macronutrient and fatty acid intake (assessed using 24 h recall) and MetS were analyzed using multivariable nutrient density substitution models. Overall, protein consumption significantly increased the likelihood of high blood pressure (HBP) and significantly lowered the likelihood of having low levels of high-density lipoprotein cholesterol (HDL-C). In an isoenergetic state, the intake of protein instead of carbohydrates (CHOs) and total fat, reduced the likelihood of elevated triglycerides by 6.7% and 6.6%, respectively. The intake of CHOs instead of protein and total fat, reduced the likelihood of HBP by 2.2% and 2.8%, respectively. In the same isoenergetic state, the intake of saturated fatty acids (SFAs) instead of mono-unsaturated fatty acids (MUFAs) increased the likelihood of HBP by 9.8%, whereas the intake of polyunsaturated fatty acids (PUFAs) instead of SFAs decreased the likelihood of HBP by 9.4%. The current study showed that when total food energy intake is kept constant, a diet that is high in protein, CHOs and PUFAs reduces triglycerides and BP, whereas the intake of total fat and SFAs had the opposite effect. It should, however, be noted that these outcomes were produced using mathematical models, as such we recommend further prospective studies in real life that will reveal the actual associations between the consumption of macronutrients and fatty acids and MetS and its components.

Abstract
IntroductionCamellia oil (CO), a common edible oil in China, contains a variety of active ingredients. In this study, we explored the combining effect and optimal feeding time of CO and squalene on hyperlipemia-induced reproductive damage rats and probably provided supportive data for use of CO for health benefits.MethodsWe established the hyperlipidaemia-induced reproductive damage model, and then the successfully modeled rats were randomly classified into four groups including a model control (MC) group, a camellia oil (CO) group, a camellia oil + squalene (COS) group, and a sildenafil (SN) group, which were feeding with different subjects during days 30 and 60. The normal (NC) group was fed under the same conditions.ResultsOur results showed that compared with the MC group, the CO, COS, and SN groups could significantly decline the serum TG, TC and LDL-C levels, increase the serum testosterone levels, the sperm counts in epididymidis and organ coefficients of penises, and no pathological change in penis and testis at days 30 and 60. Compared with the pure CO, the mixture of CO and squalene could significantly enhance the effect of decreasing the concentrations of TG, TC, and LDL-C and increasing the serum testosterone level and sperm count of epididymal tail, and the results of day 30 were better than those of day 60.DiscussionCO and squalene have a combining effect on lowering blood lipid, improving the level of testosterone and the number of epididymal tail sperm, and promoting the recovery of erectile and sexual function on hyperlipidemia-induced reproductive damage rats on day 30.

Abstract
Sexual function which comprises of desire, arousal, orgasm and satisfaction and pain, involves coordinated physiologic responses from multiple different pathways. Sexual dysfunction (SD) occurs when these domains of the sexual response cycle are affected. SD is a common but under-recognized non-motor feature in Parkinson's disease (PD), a common age-related neurodegenerative disorder. SD significantly affects the quality of life of PD patients and their partners. Advanced age, gender, hormone deficiency, neuropsychiatric and medical comorbidities contribute to SD in PD. Possible potential pathological mechanisms include vasculogenic, endocrinologic, neurogenic and psychogenic factors. Various therapeutic interventions, both pharmacological and non-pharmacological modalities have been suggested to improve SD in PD. However, erectile dysfunction (ED) is the only SD with evidence-based treatment available. Non-pharmacological therapies are also offering promising evidence in the improvement of SD. A multidisciplinary approach in the assessment, investigation, and treatment is needed to address the real life complex issues (gender and comorbidities, neurobiological, vasoactive, hormonal as well as psychosocial aspects). Future clinical studies with validated and standardized methods in assessing SD as well as experimental models will be necessary for better insight into the pathophysiology. This would facilitate appropriate therapy and improve sexual rehabilitation in PD patients.

[PMID: 34912427 PMCID: PMC8613049 DOI: 10.12669/pjms.37.7.4257] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Revised: 05/24/2021] [Accepted: 06/03/2021] [Indexed: 12/20/2022] Open
Abstract
Objective: To evaluate the effect and clinical significance of tadalafil combined with atorvastatin on hemodynamics and sexual function in middle-aged and elderly patients with hyperlipidemia complicated with Erectile dysfunction (ED). Methods: Eighty patients with hyperlipidemia complicated with ED who were treated at The Second Hospital of Hebei Medical University from January 2019 to June 2020 were selected. Using a completely randomized design experimental method, these 80 patients were randomly divided into two groups: the experimental group and the control group, with 40 cases in each group. The control group was treated with a single drug, atorvastatin calcium, while the experimental group was given tadalafil orally on the basis of the control group for 3 months. Changes in the levels of inflammatory factors such as IL-6, TNF and CRP, adverse drug reactions, changes in hemodynamic indicators such as HSV, LSV, PSV, HCT and ESR before and after treatment, as well as changes in sexual function after treatment were compared and analyzed between the two groups. Results: TNF-a, CRP and IL-6 in the experimental group were significantly lower than those in the control group after treatment, with statistically significant differences (p<0.05). There was no significant difference in the incidence of adverse drug reactions between the two groups (p=0.18). After treatment, hemodynamic indexes and sexual function indexes of the experimental group were significantly improved compared with those in the control group, with statistically significant differences (p<0.05). Conclusion: A significant improvement effect can be achieved by tadalafil combined with atorvastatin on hemodynamics and sexual function in middle-aged and elderly patients with hyperlipidemia complicated with ED. At the same time, the combination of the two has synergism on inflammatory factors and blood rheology, and the incidence of adverse reactions is not significantly increased.

Abstract
BACKGROUND The causal effects of individual risk factors of metabolic syndrome on erectile dysfunction (ED) are still unclear. OBJECTIVES To evaluate the causal effect of risk factors of metabolic syndrome on ED through Mendelian randomization (MR). MATERIALS AND METHODS Data for risk factors were obtained from multiple databases with 173,082-757,601 individuals, and that for ED were collected from a genome-wide association study including 223,805 Europeans. We performed univariate MR analysis using inverse-variance weighted, MR-Egger, weighted-median, weighted mode methods and multivariable MR analysis to evaluate the total and direct causal effects. RESULTS The univariable MR supported that type 2 diabetes mellitus (odds ratios [OR] = 1.14, 95% confidence intervals [CI]: 1.08-1.21, p < 0.001) and body mass index (BMI) (OR = 1.27, 95% CI: 1.12-1.44, p < 0.001) were associated with ED. After excluding the SNPs associated with BMI and other risk factors, the results of multivariable MR for T2D (OR = 1.15, 95% CI: 1.05-1.25, p = 0.001) remained consistent. However, the results of multivariable MR provided limited evidence for the causality between BMI and ED (OR = 1.06, 95% CI: 0.88-1.29, p = 0.532). For systolic blood pressure and lipid components (low-density lipoprotein, high-density lipoprotein and triglycerides), both univariable and multivariable MR failed to offer sufficient evidence to confirm their causal effect on ED. CONCLUSION T2D showed a direct causal effect on ED independent of obesity and dyslipidemia.

Abstract
The aim of the study was to assess the relationship between prolactin levels and sexual dysfunction in patients with schizophrenia who use olanzapine medication. The potential risk factors of hyperprolactinemia and sexual dysfunction were also investigated. Patients with schizophrenia undergoing olanzapine monotherapy were invited to participate in this cross-sectional study. The Arizona Sexual Experiences Scale (ASEX) and the Positive and Negative Syndrome Scale were used to evaluate subjective sexual dysfunction and psychopathology, respectively. Levels of prolactin and metabolic parameters were also measured. In total, 279 participants with schizophrenia were recruited. The overall incidences of hyperprolactinemia, sexual dysfunction, and metabolic syndrome were 51.6, 53.8, and 43.7%, respectively. Higher ASEX scores, higher insulin levels, female sex, and younger age were associated with hyperprolactinemia. Prolactin level was significantly correlated with ASEX score. Elevated prolactin levels, concomitant antidepressant, increased insulin resistance, longer illness duration, and female sex were associated with sexual dysfunction. Female participants recorded higher levels of sexual dysfunction than their male counterparts did, whereas male participants had comparatively lower prolactin levels and lower rates of spousal partnership. Hyperprolactinemia, metabolic syndrome, and sexual dysfunction are prevalent in patients with schizophrenia treated with olanzapine. Clinicians should maintain awareness of these problems and monitor them regularly with their patients.

Abstract
INTRODUCTION Many investigators have found a detrimental effect on sexual functioning developed by hypothyroidism in both sexes, but a cumulative analysis has not been conducted. AIM This study aims to summarize and quantify the association between overt or subclinical hypothyroidism and the risk of sexual dysfunction (SD) through a meta-analysis. METHODS 4 electronic databases were systematically searched. The quality of evidence was rated by the GRADE approach. This meta-analysis was registered on the PROSPERO (ID: CRD42020186967). MAIN OUTCOME MEASURE The strength of the relationship between overt/subclinical hypothyroidism and SD was quantified by presenting the relative risk (RR) with its 95% confidence interval (CI). RESULTS 7 studies involving 460 patients with hypothyroidism and 2,143 healthy controls were included in this meta-analysis. Among the 7 included studies, 2 studies were provided the data of both overt and subclinical hypothyroidism. Pooled results from 4 included studies investigating overt hypothyroidism indicated that overt hypothyroidism led to significant SD in both sexes (RR = 2.26, 95% CI: 1.42 to 3.62, P = 0.001), while synthetic RR of 5 eligible studies reporting subclinical hypothyroidism failed to find a positive association between subclinical hypothyroidism and SD (RR = 1.3, 95% CI: 0.85 to 1.99, P = 0.229), irrespective of gender (all P > 0.05). Subgroup analyses revealed that women with overt hypothyroidism rather than men with overt hypothyroidism were correlated with a significant higher risk of SD. The quality of evidence in the study of overt hypothyroidism and subclinical hypothyroidism was considered low and moderate, respectively. CONCLUSION SD is a devastating problem in female patients with clinical hypothyroidism but insusceptible in either women or men with subclinical hypothyroidism. Clinicians should be aware of these phenomena and manage the sufferers accordingly in clinical practice. More rigorous studies are still needed to validate this evidence. Shen M, Li X, Wu W, et al.

Abstract
AIMS To investigate factors contributing to pre and postoperative urethral function in male patients who underwent robot-assisted radical prostatectomy (RARP) using the urethral pressure profile (UPP). METHODS Study A A total of 313 patients who underwent RARP between April 2013 and March 2015 were prospectively investigated. UPP was performed preoperatively in all patients. Correlation and multiple regression analyses were performed to investigate predictive factors for low preoperative maximum urethral closure pressure (MUCP). Study B To validate the predictive factors for low preoperative MUCP obtained in Study A, 755 patients who underwent RARP between May 2010 and October 2017 were retrospectively examined. Relationships between the time to pad-free status and the following factors were investigated: number of predictive factors, nerve-sparing surgery, and vesicourethral anastomosis (VUA) methods (barbed vs. nonbarbed suture). RESULTS Study A A total of 187 patients were enrolled. Multivariate analysis revealed that older age, large prostate volume, low erectile function domain scores in International Index Erectile Function 15, and use of calcium channel blockers were significantly associated with low preoperative MUCP. Study B A total of 515 patients were included. Cox proportional hazard regression showed that the number of predictive factors and VUA method were significantly associated with the time to pad-free status. CONCLUSIONS Our study demonstrated that older age, larger prostate volume, poor erectile function, and calcium channel blocker use could be predictive markers for recovery from postprostatectomy urinary incontinence.

Abstract
There is considerable interest in understanding the genetics of erectile dysfunction (ED). Since early twin studies that suggested a genetic component to ED, multiple candidate gene studies have identified genetic variants that may be associated with ED. Genome-wide association studies (GWAS) have overcome some of the criticism of the candidate gene approach. Two recent GWAS studies have identified loci near SIM1 that may be associated with ED and have renewed interest in the leptin melanocortin signaling pathway. We review the current literature on the genetic basis of ED by highlighting several candidate genes and genetic variants associated with ED.

Abstract
Erectile dysfunction (ED) is a common sexual disorder in adult males and one of the most important factors affecting their quality of life and that of their partners. Although PDE5 inhibitors (PDE5is) are the first choice for improving erectile function, there is a substantial proportion of ED patients, termed PDE5i nonresponders, who do not respond to PDE5is. Because of the lack of effective therapies, these patients always have serious social and psychological problems due to ED, which should be addressed. Here, we review the available literature about ED and PDE5is and propose several strategies for mitigating ED in PDE5i nonresponders.

Abstract
Patients with metabolic syndrome (MetS) often exhibit generalized endothelial and cardiac dysfunction with decreased nitric oxide (NO) production and/or bioavailability. Since phosphodiesterase 5 (PDE5) inhibitors restore NO signaling, we hypothesized that chronic treatment with long-acting PDE5 inhibitor tadalafil may enhance plasma NO levels and reduce cardiac dysfunction following ischemia/reperfusion (I/R) injury in C57BL/6NCrl-Leprdb-lb/Crl mice with MetS phenotypes. Adult male MetS mice were randomized to receive vehicle solvent or tadalafil (1 mg/kg,i.p.) daily for 28 days and C57BL/6NCrl mice served as healthy wild-type controls. After 28 days, cardiac function was assessed by echocardiography and hearts from a subset of mice were isolated and subjected to 30 min of global ischemia followed by 60 min of reperfusion (I/R) in ex vivo Langendorff mode. Body weight, blood lipids, and glucose levels were elevated in MetS mice as compared with wild-type controls. The dyslipidemia in MetS was ameliorated following tadalafil treatment. Although left ventricular (LV) systolic function was minimally altered in the MetS mice, there was a significant diastolic dysfunction as indicated by reduction in the ratio of peak velocity of early to late filling of the mitral inflow, which was significantly improved by tadalafil treatment. Post-ischemic cardiac function, heart rate, and coronary flow decreased significantly in MetS mice compared to wild-type controls, but preserved by tadalafil treatment. Myocardial infarct size was significantly smaller following I/R, which was associated with higher plasma levels of nitrate and nitrite in the tadalafil-treated MetS mice. In conclusion, tadalafil induces significant cardioprotective effects as shown by improvement of LV diastolic function, lipid profile, and reduced infarct size following I/R. Tadalafil treatment enhanced NO production, which may have contributed to the cardioprotective effects.

Abstract
A growing body of evidences demonstrated that sexuality is an important topic in the clinical research of eating disorders (EDs), due to its association with specific psychopathological features, and etiological factors. The present review took into consideration the complex relationship between sexual behaviours, hormonal alterations and EDs psychopathology. Studies pertaining sexual behaviours in EDs were divided into those focusing on sexual dysfunctions, and those related to risky sexual behaviours. The limited number of studies on sexual dysfunctions, reported a controversial association with weight status and hormonal alterations, and a clear relationship with severity of specific psychopathology (e.g. body image disturbance). Risky sexual behaviours have been associated with impulsivity and dissociation, as well as with abnormal stress response. Finally, both restriction and uncontrolled eating have been found to be responsible for several complex metabolic alterations, determining varied sexual and gynecologic problems, such as amenorrhea, hypogonadism, genital vascular problems, infertility, and miscarriage, although it is also possible that alterations in feeding and stress hormones contribute to altered eating behaviour.

Abstract
BACKGROUND Diet is associated with self-reported indices of sexual health. The mechanisms responsible for these changes remain poorly understood. AIM To investigate the hemodynamic and histological impact of dietary change in a rat model of hyperlipidemia-associated erectile dysfunction. METHODS 40 2-month old male Sprague-Dawley rats were divided into 4 groups. 10 rats were fed a diet of standard chow and served as negative controls (N group). The remaining 30 age-matched rats were divided at random into 3 groups: (i) high-fat diet for 5 months starting at age 5 months (H group); (ii) high-fat diet for 5 months starting at age 4 months followed by 1 month of standard chow (H+N1M group); and (iii) high-fat diet for 5 months starting at age 2 months followed by 3 months of standard chow (H+N3M group). All rats underwent erectile function testing and sacrifice at age 10 months. OUTCOMES Intracavernous pressure (ICP) and mean arterial pressure (MAP) were measured to evaluate erectile function. Blood samples were collected to measure serum testosterone and lipid levels, and penile tissue specimens were obtained for histological examination. RESULTS Total body weight, low-density lipoprotein, and serum glucose were significantly higher in the H group compared with the N and H+N3M groups. Serum high-density lipoprotein level was significantly lower in the H group compared with the N and H+N3M groups. The mean ICP/MAP ratio was significantly lower in the H group compared with the N and H+N3M groups (0.33 ± 0.05 vs 0.79 ± 0.07 vs 0.73 ± 0.13; P < .05 for both). Markers for intracorporal neuronal nitric oxide synthase and endothelial cells were more weakly expressed in the H group compared with the N and H+N3M groups. There was no significant difference in smooth muscle content among the groups. Mean cavernosal oxidative stress and the apoptotic index were significantly higher in the H group compared with the N and H+N3M groups. No significant between-group differences were noted with respect to serum testosterone; the H group had significantly higher serum glucose and low-density lipoprotein levels, effects that were partially mitigated in the H +N1M and H+N3M groups. CLINICAL TRANSLATION Administration of a healthy diet is associated with normalization of functional and histological penile defects associated with a high-fat diet. STRENGTHS & LIMITATIONS Metabolic changes were clearly linked to functional improvements in penile blood flow. Differences between rat and human lipoprotein metabolism are a limitation of this study. CONCLUSION Dietary changes may have positive effects on penile hemodynamics in a rat model of hyperlipidemia-associated erectile dysfunction. Huang Y-C, Ho D-R, Lin J-H, et al.

Erectile dysfunction in patients with arterial hypertension. Cardiovascular risk and impact on their quality of life. Med Clin (Barc) 2019; 152:209-215. [PMID: 29996971 DOI: 10.1016/j.medcli.2018.05.022] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Revised: 05/25/2018] [Accepted: 05/30/2018] [Indexed: 11/20/2022]
Abstract
OBJECTIVES Estimate the frequency of erectile dysfunction in patients with essential hypertension and associated variables, degree of control, cardiovascular risk and the impact on quality of life. MATERIAL AND METHODS Type of study: Observational study of prevalence in men with essential hypertension. MEASUREMENTS Sociodemographic and comorbidity variables were collected from each patient (age, Charlson index, dyslipidaemia and prostatic hyperplasia), degree of control of essential hypertension and treatment, cardiovascular risk and metabolic syndrome. The erectile dysfunction was diagnosed by the International Index of Erectile Function (IIEF-15). Quality of life questionnaires were carried out in essential hypertension (MINICHAL), and the international scale of prostatic symptoms (IPSS). RESULTS The study included 262 hypertensive men with an average age of 65.84years. Erectile dysfunction was presented in 46.1%, being severe in 54.9%. The bivariate analysis shows an independent association between erectile dysfunction and the variables: age, Charlon index, dyslipidaemia, benign prostatic hypertrophy, diastolic blood pressure, years of diagnosis of hypertension, number of treatments, Regicor and Framingham-Wilson, glycaemia, creatinine and GPT, glomerular filtration through the MDRD formula, irritative symptomatology (IPSS) and somatic manifestations (MINICHAL). The final multivariate model found association with age, presentation of dyslipidaemia, prostatic hyperplasia and metabolic syndrome. CONCLUSIONS Erectile dysfunction is significantly associated with age, dyslipidaemia, benign prostatic hypertrophy and metabolic syndrome.

Endothelial colony forming cells from human umbilical cord blood improved severe erectile dysfunction in obese type II diabetic rats. Life Sci 2018; 207:272-283. [PMID: 29920249 DOI: 10.1016/j.lfs.2018.06.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2018] [Revised: 06/07/2018] [Accepted: 06/15/2018] [Indexed: 01/03/2023]
Abstract
AIM To investigate the effect of intracavernous injection of human umbilical cord blood derived endothelial colony forming cells (HUCB ECFCs) on erectile dysfunction (ED) in Zucker Diabetic Fatty (ZDF) rat model. METHODS Erectile function was assessed by cavernous nerve electrostimulation in ZDF rats aged 20-28 weeks. Following confirmation of severe ED at the age of 28 weeks, 21 ZDF rats were randomly assigned to three experimental groups: 1 million ECFCs, 2 million ECFCs, and phosphate buffered saline (PBS). Four weeks after intracavernous injection, the efficacy of ECFCs was quantified by intracavernous pressure (ICP) measurement, Masson's trichrome staining, immunohistologic and immunoblot analyses and TUNEL assay. KEY FINDINGS Intracavernous ECFC administration improved ICP in a dose-dependent manner in comparison to the age-matched PBS group. Functional improvement in ICP was accompanied by a significant restoration of the cavernosal endothelial and smooth muscle cell content and cavernosal nerve function. The percentage eNOS and nNOS positive cavernosal cells, and their respective protein expression levels and nNOS positive cells in the dorsal penile nerve in 2 million ECFCs treated groups were significantly higher than the PBS group. TUNEL stain quantification showed a significant decrease in cavernosal apoptosis following ECFC treatment. SIGNIFICANCE The results are expected to provide a scientific basis to further study the clinical application of HUCB ECFCs in ameliorating ED in human. CONCLUSIONS HUCB ECFCs significantly improved severe ED in ZDF rats through improvement of the nerve and endothelium function and restoration of smooth muscle in the cavernosum by overcoming the cavernosal apoptosis.
