Abstract
Background Previous observational studies have reported a possible association between circulating lipids and lipid-lowering drugs and male infertility (MIF), as well as the mediating role of circulating vitamin D. Then, due to issues such as bias, reverse causality, and residual confounding, inferring causal relationships from these studies may be challenging. Therefore, this study aims to explore the effects of circulating lipids and lipid-lowering drugs on MIF through Mendelian randomization (MR) analysis and evaluate the mediating role of vitamin D. Method Genetic variations related to lipid traits and the lipid-lowering effect of lipid modification targets are extracted from the Global Alliance for Lipid Genetics Genome-Wide Association Study. The summary statistics for MIF are from the FinnGen 9th edition. Using quantitative expression feature loci data from relevant organizations to obtain genetic variations related to gene expression level, further to explore the relationship between these target gene expression levels and MIF risk. Two-step MR analysis is used to explore the mediating role of vitamin D. Multiple sensitivity analysis methods (co-localization analysis, Egger intercept test, Cochrane's Q test, pleiotropy residuals and outliers (MR-PRESSO), and the leave-one-out method) are used to demonstrate the reliability of our results. Result In our study, we observed that lipid modification of four lipid-lowering drug targets was associated with MIF risk, the LDLR activator (equivalent to a 1-SD decrease in LDL-C) (OR=1.94, 95% CI 1.14-3.28, FDR=0.040), LPL activator (equivalent to a 1-SD decrease in TG) (OR=1.86, 95% CI 1.25-2.76, FDR=0.022), and CETP inhibitor (equivalent to a 1-SD increase in HDL-C) (OR=1.28, 95% CI 1.07-1.53, FDR=0.035) were associated with a higher risk of MIF. The HMGCR inhibitor (equivalent to a 1-SD decrease in LDL-C) was associated with a lower risk of MIF (OR=0.38, 95% CI 0.17-0.83, FDR=0.39). Lipid-modifying effects of three targets were partially mediated by serum vitamin D levels. Mediation was 0.035 (LDLR activator), 0.012 (LPL activator), and 0.030 (CETP inhibitor), with mediation ratios of 5.34% (LDLR activator), 1.94% (LPL activator), and 12.2% (CETP inhibitor), respectively. In addition, there was no evidence that lipid properties and lipid modification effects of six other lipid-lowering drug targets were associated with MIF risk. Multiple sensitivity analysis methods revealed insignificant evidence of bias arising from pleiotropy or genetic confounding. Conclusion This study did not support lipid traits (LDL-C, HDL-C, TG, Apo-A1, and Apo-B) as pathogenic risk factors for MIF. It emphasized that LPL, LDLR, CETP, and HMGCR were promising drug targets for improving male fertility.

Abstract
PURPOSE Statins are one of the most prescribed classes of drugs worldwide to treat hypercholesterolemia and dyslipidemia. By lowering the level of cholesterol, the use of statin could cause a reduction in testosterone levels. The objective was to evaluate whether the continued use of statins in patients with hypercholesterolemia causes a deficiency in testosterone and other sex hormones. MATERIALS AND METHODS Systematic Review with Meta-analysis, performed in Embase, Medline and Cochrane databases, until May 2023; PROSPERO CRD42021270424protocol. Selection performed by two independent authors with subsequent conference in stages. Methodology based on PRISMA statement. There were selected comparative studies, prospective cohorts (CP), randomized clinical trials (RCT) and cross-sectional studies (CSS) with comparison of testosterone levels before and after statin administration and between groups. Bias analysis were evaluated with Cochrane Tool, The Newcastle-Ottawa Scale (NOS), and using the Assess the Quality of Cross-sectional studies (AXIS) tool. RESULTS There were found on MedLine, Embase and Cochrane, after selected comparative studies, 10CP and 6RCT and 6CSS for the meta-analysis. In the Forrest plot with 6CSS, a correlation between patients with continuous use of statins and a reduction in total testosterone was evidenced with a statistically significant reduction of 55.02ng/dL (95%CI=[39.40,70.64],I²=91%,p<0.00001).In the analysis with 5RCT, a reduction in the mean total testosterone in patients who started continuous statin use was evidenced, with a statistical significance of 13.12ng/dL (95%CI=[1.16,25.08],I²=0%,p=0.03). Furthermore, the analysis of all prospective studies with 15 articles showed a statistically significant reduction in the mean total testosterone of 9.11 ng/dL (95%CI=[0.16,18.06],I²=37%,p=0.04). A reduction in total testosterone has been shown in most studies and in its accumulated analysis after statin use. However, this decrease was not enough to reach levels below normal. CONCLUSION Statins use causes a decrease in total testosterone, not enough to cause a drop below the normal range and also determines increase in FSH levels. No differences were found in LH, Estradiol, SHBG and Free Testosterone analysis.

Abstract
Memory impairment is a result of multiple factors including amyloid-beta (Aβ) accumulation. Several receptors are mediated for Aβ transport and signaling. Moreover, blood lipids are involved in Aβ signaling pathway through these receptors. Mediated blood lipid level by statins aims to regulate Aβ signaling cascade. First, the structure of receptors was taken from the RCSB PDB database and prepared with MGLTools and AutoDock tool 4. Second, the ligand was prepared for docking through AutoDock Vina. The binding affinity was calculated, and the binding sites were determined through LigPlot+ software. Besides, pharmacokinetic properties were calculated through multiple software. Finally, a molecular dynamics (MD) simulation was conducted to evaluate ligands stability along with clustering analysis to evaluate proteins connection. Our molecular docking and dynamic analyses revealed silymarin as a potential inhibitor of acetylcholinesterase (AChE), P-glycoprotein, and angiotensin-converting enzyme 2 (ACE2) with 0.704, 0.85, and 0.83 Å for RMSD along with -114.27, -107.44, and -122.51 kcal/mol for free binding energy, respectively. Moreover, rosuvastatin and quercetin have more stability compared to silymarin and donepezil in complex with P-glycoprotein and ACE2, respectively. Eventually, based on clustering and pharmacokinetics analysis, silymarin, rosuvastatin, and quercetin are suggested to be involved in peripheral clearance of Aβ. The bioactivity effects of mentioned statins and antioxidants are predicted to be helpful in treating memory impairment in Alzheimer's disease (AD). Nevertheless, mentioned drug effect could be improved by nanoparticles to facilitate penetration of the blood-brain barrier (BBB).

Abstract
BACKGROUND Erectile dysfunction (ED) is a major health problem that affects a significant proportion of the general population, and its prevalence is even higher in patients with CV risk factors and/or disease. ED and cardiovascular (CV) disease share several common pathophysiological mechanisms, and thus, the potential role of ED as a predictor of CV events has emerged as a significant research aspect. OBJECTIVE The purpose of this review is to present and critically discuss data assessing the relation between ED and CV disease and the potential predictive value of ED for CV events. METHODS A comprehensive review of the literature has been performed to identify studies evaluating the association between ED and CV disease. RESULTS Several cross-sectional and prospective studies have examined the association between ED and CV disease and found an increased prevalence of ED in patients with CV disease. ED was shown to independently predict future CV events. Importantly, ED was found to precede the development of overt coronary artery disease (CAD) by 3 to 5 years, offering a "time window" to properly manage these patients before the clinical manifestation of CAD. Phosphodiesterase type 5 inhibitors are the first-line treatment option for ED and were shown to be safe in terms of CV events in patients with and without CV disease. CONCLUSION Accumulating evidence supports a strong predictive role of ED for CV events. Early identification of ED could allow for the optimal management of these patients to reduce the risk for a CV event to occur.

Abstract
Previous data have shown that patients with metabolic syndrome (MetS) and lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement (BPE) could be refractory to the medical treatment. In this context, the evidence suggests a role for statin use in LUTS/BPE patients. The present systematic review aimed to evaluate the impact of statins on the treatment of men with LUTS/BPE. This review has been registered on PROSPERO (CRD42019120729). A systematic review of English-language literature was performed up to January 2020 in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA statement) criteria. Retrieved studies had to include adults with LUTS connected to BPE treated with statins drugs for metabolic syndrome. After removing duplicates, a total of 381 studies were identified by the literature search and independently screened. Of these articles, 10 fit the inclusion criteria and were further assessed for eligibility. Data from our systematic review suggest that a long-term therapy with statins, at least 6 months, is required to achieve significant impacts on prostate tissue and LUTS. Moreover, besides statins' direct activity, the risk reduction of LUTS might be connected to the improvement of hypercholesterolemia and MetS. The role of statins for the treatment of LUTS/BPE may be beneficial; however, evidence from robust studies is not enough, and more clinical trial are required.

Abstract
Current guidelines recommend statin therapy for all adult patients with coronary artery disease irrespective of sex. Over recent years, some concerns have been raised concerning the effects of statins on endogenous steroid hormones synthesis. The aim of this review was to summarize the effects of statins on endogenous sex hormones in order to clarify their role and safety in different clinical settings. Results suggest that HMG-CoA inhibitors may slightly impair adrenal and/or gonadal steroid hormone production. In men, statins do not cause any clinically-relevant harmful effects on erectile function and spermatogenesis and, in women, statins have beneficial effects in treatment of polycystic ovary syndrome (PCOS). Additional research is needed to provide specific clinical recommendations concerning this topic.

Abstract
PURPOSE The aim of the study was to analyze factors affecting sexual activity in individuals with and without stroke, ages 40-59 years, in a national, cross-sectional, population-based sample derived from the National Health and Nutrition Examination Survey (NHANES). DESIGN Descriptive, cross-sectional survey. METHODS Data were obtained from the NHANES (2011-2012) data set from individuals (N = 3,649) completing items related to cardiovascular risk factors, drugs, and sexual activity. Data were analyzed using chi-square, t tests, and logistic regression. FINDINGS Overall, number of drugs, smoking, and depression significantly predicted sexual activity. When comparing sexually active to not sexually active, those with stroke had significantly less sexual activity (t = 2.822, p = .005) and reduced sexual activity per week or month (χ = 16.275, p = .005, df = 4). Those taking angiotensin-converting enzyme inhibitors and statins had reduced sexual activity. CONCLUSIONS/CLINICAL RELEVANCE Findings illustrate the importance of risk factor modification and nurses engaging in sexual assessment, education, and counseling to support sexual quality of life in younger individuals with stroke.

Abstract
BACKGROUND The 3-Hydroxy-3-MethylGlutaryl-CoA reductase inhibitors, better known as statins, are used extensively in the treatment of dyslipidemia and cardiovascular risk reduction. They have also demonstrated a variety of non-lipid lowering, or pleiotropic effects. Pertaining to the endocrine system the benefits of statins can extend to patients with the polycystic ovarian syndrome and thyroid disease. However, there is also increasing evidence that statin use can lead to deleterious effects in different organs, including worsening glycemia and the development of diabetes mellitus. OBJECTIVE The aim of this review is to describe the most relevant and updated evidence regarding the pleiotropic effects of statins in endocrine disorders. METHODS We did a systematic review of scientific articles published in PubMed regarding the effects of statins on the different aspects of the endocrine system up until June 5th of 2018. RESULTS We identified preliminarily 61 publications, of which 4 were excluded due to having abstract format only, and 5 were excluded for not containing pertinent information to the study. CONCLUSION Several aspects of the endocrine system have been shown to be influenced by the pleiotropic effects that statins exert, however, the benefits of statins on cardiovascular morbidity and mortality largely outweigh this deleterious effect, and statin therapy should continue to be recommended.

Abstract
BACKGROUND The aim of this meta-analysis was to understand the relationship between statin with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). METHODS A systematic literature search was conducted using PubMed, Embase, Cochrane Library, Chinese Medical and Biological Literature Database, China HowNet, Vip, and Wanfang. We calculated pooled odds ratios (OR) and 95% CI and standardized mean difference (SMD). Using Stata 12.0 and Review 5.3 for meta-analysis. RESULTS This meta-analysis included 11 articles and 49,128 participants. Results show statins could not reduce the incidence of BPH [OR = 0.77 (0.57, 1.03, P = .08]. For patients over 60 years old, statins could reduce the incidence of BPH [OR = 0.35 (0.22, 0.55), P < .0001]. Statins can slow down the progression of LUTS in BPH [SMD = -0.32 (-0.54, -0.10), P = .004], but there is no significant correlation between them in patients taking drugs for less than 1 year. CONCLUSION Statins have no significant effect on the incidence of BPH, but statins can reduce the risk of BPH for patients over 60 years old. For patients with hyperlipidemia, the duration of medication is more than 1 year, which can slow down the progression of LUTS. However, more high-quality and large sample size studies are needed to further improve and verify.

Abstract
OBJECTIVE A debate is open on the effects of lipid-lowering drugs on sexual function. We aimed to investigate the effect of atorvastatin use on penile intracavernosal pressure (ICP) and cavernosal morphology. MATERIAL AND METHODS Fourteen mature male Sprague-Dawley-rats were randomly assigned to either the control group (which received standard food and water ad libitum) or the atorvastatin group (which received standard food, water, and statin) for twelwe weeks. At the end of the study, ICPs were measured with cavernosometry. Penectomy specimens were histologically examined. RESULTS The following mean values were obtained for the control and atorvastatin groups, respectively: pre-study body weights (350±16.9 g and 331.4±24.9 g); post-study body weights (356±18 g and 368±22.5 g (p>0.05); ICPs at 5 V (5.96±5.16 mmHg and 2.11±1.22 mmHg (p=0.07)); ICPs at 10 V (18.28±14.1 mmHg and 5.56±5.58 mmHg) (p=0.09); testosterone (1.23±0.78 and 0.78±0.58 mmol/dL) (p=0.39); blood glucose (151±22 mg/dL and 168.6±16.2 mg/dL) (p=0.12); triglyceride (93.4±19.8 mg/dL and 52.1±18.6 mg/dL) (p=0.01); total cholesterol (50.2±7.2 mg/dL and 47.7±6.6 mg/dL) (p=0.51); and low-density lipoprotein (LDL) cholesterol (10.0±4.4 mg/dL and 3.5±2.1 mg/dL) (p=0.01). The mean collagen thickness was similar (p=0.09); but the mean elastin thickness increased in the atorvastatin group (p=0.01). CONCLUSION The present study showed that the use of atorvastatin reduced the intracavernosal pressure in 10 V stimulation, and minimally decreased testosterone levels in rats, within a short period of time. When statin treatment is considered for its protective properties on cardiovascular system or for its lipid-lowering effect. It should be kept in mind that atorvastatin may also adversely contribute to erectile dysfunction.

Abstract
BACKGROUND Erectile dysfunction has been reported as an adverse effect of statin therapy. METHODS We performed a meta-analysis of randomized trials and observational studies that compared statin users versus non-statin users and reported data regarding new onset of erectile dysfunction in men with established cardiovascular disease or cardiovascular disease risk factors. We used DerSimonian-Laird and Peto models to construct the summary estimates risk ratio. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) to assess the overall quality of evidence for new-onset erectile dysfunction. RESULTS Three randomized trials and 3 observational studies were identified, with 69,448 men, of whom 24,661 were statin users. Statin use was not associated with an increased risk of new onset of erectile dysfunction by random effects model or fixed effect model (risk ratio 0.96; 95% confidence interval, 0.84-1.10; P = .58; and odds ratio 0.95; 95% confidence interval, 0.88-1.02; P = .20, respectively). This effect was similar in randomized trials and observational studies (Pinteraction = .86). Randomized trials provided a moderate quality of evidence, and observational studies provided a very low quality of evidence by the GRADE assessment. Random effects meta-regression analyses revealed no difference in treatment effect according to age or diabetes mellitus (P = .83 and P = .74, respectively). CONCLUSIONS Among men with established cardiovascular disease or cardiovascular disease risk factors, statin use does not seem to be associated with a new onset of erectile dysfunction. Adequately powered and high-quality randomized trials are recommended to confirm these findings.

Abstract
BACKGROUND AND OBJECTIVE Statins are commonly used medications. Whereas some observational studies suggested an association of statin use with Barrett's esophagus and some upper gastrointestinal symptoms, there is a dearth of data on the association of statins and common esophageal conditions such as gastroesophageal reflux disease and esophagitis. The aim of this study is to examine the association of statins with esophageal conditions. METHODS This is a retrospective cohort study using regional military healthcare data (1 October, 2003 to 1 March, 2012). The primary analyses evaluated the odds of: esophagitis; symptoms of esophagitis; gastroesophageal reflux disease/dyspepsia; and esophageal complications of gastroesophageal reflux disease in four propensity score-matched cohorts of statin users and non-users (propensity score-overall, propensity score-healthy, propensity score-women, and propensity score-men cohorts). Secondary and sensitivity analyses were performed. RESULTS In the propensity score-overall cohort (n = 12,684), statin users were more likely to be diagnosed with esophagitis (odds ratio 1.11, 95% confidence interval 1.01-1.22) and gastroesophageal reflux disease/dyspepsia (odds ratio 1.18, 95% confidence interval 1.10-1.27) compared with non-users. Similar findings were seen in the propensity score-healthy cohort and in the propensity score-men cohort. In the propensity score-women cohort, the odds of esophagitis was higher among statin users compared with non-users (odds ratio 1.16, 95% confidence interval 1.02-1.32) but other outcomes were not different. In sensitivity analyses, which excluded patients with obesity, statin use was not associated with an increased odds ratio of gastroesophageal reflux disease/dyspepsia. CONCLUSION Statin therapy was associated with higher odds of being diagnosed with esophagitis and gastroesophageal reflux disease/dyspepsia. Further study is warranted to elucidate the potential role of statins in these commonly diagnosed esophageal conditions.

Abstract
BACKGROUND Sexual activity is increasingly recognized as an important aspect of quality of life for many individuals with cardiovascular disease, although less is known about the factors contributing to sexual functioning in younger adults. OBJECTIVE This study examined factors influencing sexual activity in individuals aged 40 to 59 years, comparing those reporting a cardiac condition with those without a cardiac condition, in a national population-based sample. METHODS The data were derived from the 2011 to 2012 National Health and Nutrition Examination Survey, a publicly available data set with a noninstitutionalized nationally representative sample. The sample included individuals between the ages of 40 and 59 years (N = 1741) who completed relevant items related to cardiovascular disease, cardiovascular risk factors, comorbidities, cardiac symptoms, sexual activity, and medication use. Recommended weighting was applied, and the data were analyzed using χ and logistic regression. RESULTS Overall, 94% of the sample reported sexual activity, although those with coronary artery disease, angina, and myocardial infarction engaged in significantly less sexual activity. Individuals who smoked; had a weight problem, depression, or lung problems; or experienced symptoms of shortness of breath or chest pain with exertion reported less sexual activity. Medications negatively affecting sexual function were central α agonists, potassium sparing diuretics, and antilipidemic agents. Predictors of less sexual activity were smoking, chest pain walking uphill, and weight problems. Unexpectedly more reported, sexual activity was predicted by one or more cardiac conditions. CONCLUSION In men and women ages 40 to 59 years, certain cardiac conditions, risk factors, comorbidities, symptoms, and medications negatively affected sexual activity, illustrating the need for sexual assessment and counseling to support sexual quality of life.

Abstract
PURPOSE OF REVIEW This narrative review discusses the associations of erectile dysfunction with coronary heart disease (CHD) morbidity and mortality, all-cause death and CHD risk factors. Treatment strategies for erectile dysfunction are also mentioned. RECENT FINDINGS Erectile dysfunction shares common pathways and risk factors with vascular diseases. Erectile dysfunction has been reported to independently predict CHD events, thus highlighting its role as a marker of early atherosclerosis. Erectile dysfunction prevalence may be followed by the presentation of CHD symptoms in 2-3 years, and a CHD event may occur in 3-5 years. Furthermore, erectile dysfunction has been associated with stroke, peripheral artery disease, diabetes and chronic kidney disease as well as with several CHD risk factors including hypertension, dyslipidaemia, smoking, obesity, metabolic syndrome, hyperuricaemia, arterial stiffness and obstructive sleep apnea syndrome. On the basis of these data, erectile dysfunction may be regarded as a part of polyvascular disease. SUMMARY Patients with erectile dysfunction are at an increased risk for CHD morbidity and/or mortality as well as for all-cause death. Clinicians should monitor patients with erectile dysfunction by assessing their vascular risk and preventing or adequately treating CHD risk factors. In this context, lifestyle interventions should be recommended in addition to drug treatment to attain better outcomes.
