Vasculogenic Erectile Dysfunction: The Impact of Diet and Lifestyle

Cardiometabolic Disorder and Erectile Dysfunction

Erectile dysfunction (ED), which is defined as the inability to attain and maintain a satisfactory penile erection to sufficiently permit sexual intercourse, is a consequence and also a cause of cardiometabolic disorders like diabetes mellitus, systemic hypertension, central obesity, and dyslipidemia. Although there are mounting and convincing pieces of evidence in the literature linking ED and cardiometabolic disorders, impairment of nitric oxide-dependent vasodilatation seems to be the primary signaling pathway. Studies have also implicated the suppression of circulating testosterone, increased endothelin-1, and hyperactivation of Ang II/ATIr in the pathogenesis of ED and cardiometabolic disorders. This study provides comprehensive details of the association between cardiometabolic disorders and ED and highlights the mechanisms involved. This would open areas to be explored as therapeutic targets in the management of ED and cardiometabolic disorders. It also provides sufficient evidence establishing the need for the management of cardiometabolic disorders as an adjunct therapy in the management of ED.

Impact of cardiac rehabilitation on erectile dysfunction in cardiovascular patients: a systematic review and meta-analysis

Background

Cardiovascular diseases (CVDs) and erectile dysfunction (ED) frequently co-occur, significantly affecting the quality of life of individuals.

Aim

To assess the impact of cardiac rehabilitation (CR) on ED in patients with CVD through a systematic review and meta-analysis.

Methods

This study analyzed randomized controlled trials and other studies comparing CR with usual care for adult males (≥18 years) with any cardiac disease. Literature searches were extensive, and the risk of bias was evaluated by the Cochrane Collaboration tool. Data from 6 studies involving 668 participants were included in the meta-analysis.

Outcomes

The primary outcome was the improvement in ED, as measured with the International Index of Erectile Function.

Results

A statistically significant improvement in erectile function was observed across 6 studies, with a Morris dppc2 effect size of 0.38 (95% CI, 0.17-0.59). Despite initial high heterogeneity (I 2 = 95.7%), identification and correction for selective outcome reporting bias mitigated this issue.

Clinical Translation

CR has a modest but statistically significant impact on improving ED in patients with CVD, indicating its potential positive contribution to the quality of life of this group.

Strengths and Limitations

The study's strengths include a comprehensive literature search and a rigorous methodological approach. Limitations involve high heterogeneity among studies and a low level of evidence due to small sample sizes and study quality; however, the source of heterogeneity was identified and mitigated following risk-of-bias assessment.

Conclusion

The results suggest that CR has a statistically significant but modest impact on improving ED in patients with CVD. Clinicians should consider the integration of CR into the clinical management of these individuals. This study underscores the potential for CR to contribute positively to the quality of life for patients with CVD by addressing associated ED (PROSPERO: CRD42022374625).

Association between atherogenic indexes and erectile dysfunction: a cross-sectional analysis of the National Health and Nutrition Examination Survey 2001-2004

PURPOSE

Elevated blood lipids are considered a risk factor for atherosclerosis, which can lead to erectile dysfunction. This study aimed to explore the relationship between the atherogenic index of plasma (AIP), atherogenic coefficient (AC), Castelli's risk index-I (CRI-I), Castelli's risk index-II (CRI-II), and erectile dysfunction.

METHODS

Based on the National Health and Nutrition Examination Survey (NHANES) data from 2001-2004, multivariable-adjusted logistic regression models were used to evaluate the association between AIP, AC, CRI-I, and CRI-II with ED. Smooth curve fitting was employed to assess the linear association.

RESULTS

A total of 1806 male participants with complete data were enrolled in the study. In Model 1, those in the highest tertile of AIP had a 49% increased risk of ED compared to the lowest tertile (OR 1.49; 95% CI 1.15-1.91 p = 0.0021). After adjusting for the variables of age, race, education, body mass index, and poverty income ratio (PIR), significant positive correlations were found between ED and AIP, with each 1-unit increase in AIP associated with a 65% increase in the risk of developing ED (OR 1.65; 95% CI 1.03-2.64 p = 0.0361).

CONCLUSIONS

AIP is positively associated with the development of ED in US adults. More prospective cohort studies are needed to confirm the link between AIP and ED.

Muscle Strength and Male Sexual Function

Sexual dysfunction, in particular erectile dysfunction, is a common complaint among aging men. Obesity, diabetes, hypertension, and smoking are shown to be independent risk factors for erectile dysfunction, while cardiorespiratory fitness is shown to be protective. Less is known about the role of muscle strength in male sexual function. Our objective was to study the association between male sexual function and typical cardiovascular risk factors, together with exercise and muscle strength. We included data from the fourth wave of the RHINE study. Data on anthropometrics, exercise habits, diseases, muscle strength, and sexual function were collected using questionnaires, including the Aging Males' Symptoms (AMS) scale. We used multivariable logistic regression analysis to measure the association between sexual function and body mass index (BMI), age, smoking, diabetes, hypertension, exercise and muscle strength status. We included 2116 men aged 48-75 from four Nordic-Baltic countries. BMI, age, smoking, diabetes, and hypertension were found to be associated with higher odds of reporting decreased sexual function, while reporting intact muscle strength was associated with lower odds. In a large Nordic-Baltic male study population, we show that known cardiovascular risk factors are associated with decreased sexual function, while reporting intact muscle strength is associated with lower odds of reporting decreased sexual function.

The Association between the Gut Microbiota and Erectile Dysfunction

PURPOSE

Explore the causal relationship between the gut microbiota and erectile dysfunction (ED) at phylum, class, order, family, and genus levels, and identify specific pathogenic bacteria that may be associated with the onset and progression of ED.

MATERIALS AND METHODS

The genetic variation data of 196 human gut microbiota incorporated in our study came from the human gut microbiome Genome Wide Association Studies (GWAS) dataset released by the MiBioGen Consortium. The GWAS statistics for ED were extracted from one study by Bovijn et al., which included 223,805 participants of European ancestry, of whom 6,175 were diagnosed with ED. Subsequently, Mendelian randomization (MR) analysis was carried out to explore whether a causal relationship exists between the gut microbiota and ED. Additionally, bidirectional MR analysis was performed to examine the directionality of the causal relationship.

RESULTS

Through MR analysis, we found that family Lachnospiraceae (odds ratio [OR]: 1.27, 95% confidence interval [CI]: 1.05-1.52, p=0.01) and its subclass genus LachnospiraceaeNC2004 group (OR: 1.17, 95% CI: 1.01-1.37, p=0.04) are associated with a higher risk of ED. In addition, genus Oscillibacter (OR: 1.17, 95% CI: 1.02-1.35, p=0.03), genus Senegalimassilia (OR: 1.32, 95% CI: 1.06-1.64, p=0.01) and genus Tyzzerella3 (OR: 1.14, 95% CI: 1.02-1.27, p=0.02) also increase the risk of ED. In contrast, the inverse variance weighted estimate of genus RuminococcaceaeUCG013 (OR: 0.77, 95% CI: 0.61-0.96, p=0.02) suggests that it has a protective effect against the occurrence of ED.

CONCLUSIONS

This study preliminarily identified 6 bacterial taxa that may have a causal relationship with ED, including family Lachnospiraceae, genus Lachnospiraceae NC2004 group, Oscillibacter, Senegalimassilia, Tyzzerella 3 and Ruminococcaceae UCG013. These identified important bacterial taxa may serve as candidates for microbiome intervention in future ED clinical trials.

Autophagy, a critical element in the aging male reproductive disorders and prostate cancer: a therapeutic point of view

Autophagy is a highly conserved, lysosome-dependent biological mechanism involved in the degradation and recycling of cellular components. There is growing evidence that autophagy is related to male reproductive biology, particularly spermatogenic and endocrinologic processes closely associated with male sexual and reproductive health. In recent decades, problems such as decreasing sperm count, erectile dysfunction, and infertility have worsened. In addition, reproductive health is closely related to overall health and comorbidity in aging men. In this review, we will outline the role of autophagy as a new player in aging male reproductive dysfunction and prostate cancer. We first provide an overview of the mechanisms of autophagy and its role in regulating male reproductive cells. We then focus on the link between autophagy and aging-related diseases. This is followed by a discussion of therapeutic strategies targeting autophagy before we end with limitations of current studies and suggestions for future developments in the field.

Male infertility and the human microbiome

The historical belief in urology was that the genitourinary system should be sterile in a normal, healthy, asymptomatic adult. This idea was perpetuated for decades until research revealed a diverse microbiota existing in human anatomical niches that contributed to both human health and disease processes. In recent years, the search for an etiology and modifiable risk factors in infertility has turned to the human microbiome as well. Changes in the human gut microbiome have been associated with changes in systemic sex hormones and spermatogenesis. Certain microbial species are associated with higher levels of oxidative stress, which may contribute to an environment higher in oxidative reactive potential. Studies have demonstrated a link between increased oxidative reactive potential and abnormal semen parameters in infertile men. It has also been hypothesized that antioxidant probiotics may be able to correct an imbalance in the oxidative environment and improve male fertility, with promising results in small studies. Further, the sexual partner's microbiome may play a role as well; studies have demonstrated an overlap in the genitourinary microbiomes in sexually active couples that become more similar after intercourse. While the potential applications of the microbiome to male fertility is exciting, there is a need for larger studies with uniform microbial sequencing procedures to further expand this topic.

Sexual Functions Following Cardiac Resynchronization Therapy: Evaluation of Male Patients and Their Partners

INTRODUCTION

Sexual functionality, a critical component of health-related quality of life, can decline for various reasons, including heart failure (HF). Our purpose was to prospectively evaluate male patients with HF scheduled for cardiac resynchronization therapy (CRT) in terms of sexual function, erectile function, and alterations in hormonal and biochemical parameters. In addition, we sought to determine the sexual functioning of the partners of these patients.

METHODS

 The study enrolled 103 male patients and their partners. The International Index of Erectile Function-5 (IIEF-5) was administered to all males and the Arizona Sexual Experience Scale (ASEX) questionnaire was completed by all participants, at baseline and three months after CRT.

RESULTS

 The ASEX scores of patients and partners demonstrated significant declines from baseline to post-intervention analysis. The IIEF-5 scores of patients showed a significant increase from baseline to post-intervention (p=0.001 for all).

CONCLUSION

 We conclude that sexual dysfunction is experienced by the partners of male patients with erectile dysfunction before CRT and that reversal of erectile problems with CRT yields improvements in both male and female sexual functions.

Effects of diet and antihyperglycemic drugs on erectile dysfunction: A systematic review

BACKGROUND

Erectile dysfunction is recognized as one of the complications of diabetes mellitus. To date, a wide gap of knowledge is present on the efficacy of pharmacological treatments of diabetes mellitus on erectile function, acting not only through metabolic control. Similarly, the effects of different diet regimens on erectile dysfunction are still debated.

OBJECTIVES

We aimed to explore the effects of diet and antihyperglycemic drugs, considering both old and novel therapeutic approaches, on erectile function.

MATERIALS/METHODS

We performed a systematic review, following the PRISMA guidelines. The research was conducted on studies reporting erectile dysfunction assessment in subjects with diabetes and the relationship with diet and antihyperglycemic drugs.

RESULTS

The Mediterranean diet was effective in most studies for the protection of erectile function. Furthermore, antihyperglycemic drugs seem to show an overall protective role on erectile function.

DISCUSSION/CONCLUSION

Although encouraging results are present for all classes of antihyperglycemic drugs, several studies are needed in humans, mainly on acarbose, pioglitazone, dipeptidyl-peptidase-4 inhibitors, and sodium-glucose cotransporter-2 inhibitors.

Clinical study of comprehensive TCM therapy in the treatment of damp and hot stasis erectile dysfunction

BACKGROUND

The dilemma of male sexual dysfunction has been the focus of the whole society. Erectile dysfunction (ED) is one of the common sexual dysfunctions, and traditional Chinese medicine therapy has shown potential benefits in the treatment of ED. Comprehensive therapy of traditional Chinese medicine (CTTCM) is a comprehensive application of Chinese medicine therapy for auxiliary intervention. Through preliminary clinical observations, we found that CTTCM is simple, safe, and has good efficacy; however, there is a lack of rigorous clinical trials to support its application. Therefore, we designed a randomized controlled trial to evaluate the efficacy and safety of CTTCM for patients with ED of damp-heat stasis type, and to provide evidence for the clinical application of CTTCM and the construction of a traditional Chinese medicine andrology rehabilitation system.

METHODS

In this randomized controlled study, 108 eligible patients were assigned 1:1 to the CTTCM group or the tadalafil group. The treatment period was 8 weeks and the follow-up period was 8 weeks. The primary outcome will be the International Erectile Function Score and traditional Chinese medicine Syndrome Score. Secondary outcomes will include the Erection Quality Score, Patient Health Questionnaire-9, and the 7-item Generalized Anxiety Scale. Safety results will include electrocardiogram, blood tests (including blood, liver and kidney function), urine and stool. International Erectile Function Score-5, traditional Chinese medicine Syndrome Score, Erectile Quality Score, Patient Health Questionnaire-9, 7-item Generalized Anxiety Scale and all Safety outcomes will be conducted at baseline, 2th, 4th, 6th, and 8th week. Follow-up results will be assessed at 8th week after 8 weeks' treatment.

DISCUSSION

This study will provide preliminary evidence for the efficacy and safety of traditional Chinese medicine integrated therapy in the treatment of damp-heat stasis ED. In addition, it also provides a basis for the clinical application of Chinese medicine comprehensive therapy and the construction of Chinese medicine andrology rehabilitation system.

Phenotypic modulation of vascular smooth muscle cells in the corpus spongiosum surrounding the urethral plate in hypospadias

Hypospadias is an abnormal ventral development of the penis caused by incomplete virilization of the male genital tubercle. This study investigated the phenotypic modulation of vascular smooth muscle cells (VSMCs) in the corpus spongiosum surrounding the urethral plate in hypospadias. The urethral corpus spongiosum tissue was collected for HE, Masson and α-SMA immunohistochemical staining. Spongiosum VSMCs were cultured and identified by α-SMA fluorescence. qRT-PCR and Western blotting and fluorescence were performed. The results showed that the vascular lumen of the corpus spongiosum around the urethral plate was larger and that the vascular smooth muscle layer was thicker in hypospadias. The expression of the contractile markers α-SMA and Calponin 1 in VSMCs was decreased, the expression of the synthetic marker OPN was increased, and the transcription of the phenotypic switching factors SRF and MYOCD was decreased. The expression of Ki67, PCNA and BAX was increased, and the expression of Bcl-2 was decreased. The phenotype of corpus spongiosum VSMCs in hypospadias changed from the contractional type to the synthetic type. This phenotypic modulation was associated with increased proliferation and apoptosis rates. SRF and MYOCD may be the main factors mediating the phenotypic modulation of urethral corpus spongiosum VSMCs.

Aphrodisiac Performance of Bioactive Compounds from Mimosa pudica Linn.: In Silico Molecular Docking and Dynamics Simulation Approach

Plants and their derived molecules have been traditionally used to manage numerous pathological complications, including male erectile dysfunction (ED). Mimosa pudica Linn. commonly referred to as the touch-me-not plant, and its extract are important sources of new lead molecules in drug discovery research. The main goal of this study was to predict highly effective molecules from M. pudica Linn. for reaching and maintaining penile erection before and during sexual intercourse through in silico molecular docking and dynamics simulation tools. A total of 28 bioactive molecules were identified from this target plant through public repositories, and their chemical structures were drawn using Chemsketch software. Graph theoretical network principles were applied to identify the ideal target (phosphodiesterase type 5) and rebuild the network to visualize the responsible signaling genes, proteins, and enzymes. The 28 identified bioactive molecules were docked against the phosphodiesterase type 5 (PDE5) enzyme and compared with the standard PDE5 inhibitor (sildenafil). Pharmacokinetics (ADME), toxicity, and several physicochemical properties of bioactive molecules were assessed to confirm their drug-likeness property. Molecular dynamics (MD) simulation modeling was performed to investigate the stability of PDE5–ligand complexes. Four bioactive molecules (Bufadienolide (−12.30 kcal mol⁻¹), Stigmasterol (−11.40 kcal mol⁻¹), Isovitexin (−11.20 kcal mol⁻¹), and Apigetrin (−11.20 kcal mol⁻¹)) showed the top binding affinities with the PDE5 enzyme, much more powerful than the standard PDE5 inhibitor (−9.80 kcal mol⁻¹). The four top binding bioactive molecules were further validated for a stable binding affinity with the PDE5 enzyme and conformation during the MD simulation period as compared to the apoprotein and standard PDE5 inhibitor complexes. Further, the four top binding bioactive molecules demonstrated significant drug-likeness characteristics with lower toxicity profiles. According to the findings, the four top binding molecules may be used as potent and safe PDE5 inhibitors and could potentially be used in the treatment of ED.

A factor not to be ignored in post-COVID-19 erectile dysfunction; psychological effect, a prospective study

It was aimed to show the effect of anxiety and depression on erectile dysfunction seen after coronavirus disease‐2019 (COVID‐19). Between March and July 2021, the participants completed the International Index of Erectile Function, Beck Depression Inventory and Generalised Anxiety Disorder 7 forms at the beginning and after the 1st month of the disease. We investigated the psychological impact of COVID‐19 on the development of erectile dysfunction. The mean age of 156 male patients in the study was 54.74 ± 8.01 years. It was determined that the mean International Index of Erectile Function scores of the patients before COVID‐19 were 73.42 ± 3.43 and decreased to 68.28 ± 12.86 after COVID‐19 (p < .01). The patients’ erectile function scores were significantly lower after COVID‐19 (29.45 ± 1.23, 27.69 ± 4.33, p < .01, respectively). Their Beck Depression Inventory scores were statistically significantly higher after COVID‐19 (1.69 ± 2.56, 2.22 ± 2.79, p < .01, respectively). Their Generalised Anxiety Disorder 7 scores were also statistically significantly higher after COVID‐19 (4.69 ± 1.63 6.56 ± 2.40, p < .01, respectively). A negative correlation was found between the increase in the Beck Depression Inventory score during the pandemic process and the decrease in the International Index of Erectile Function score (r = −0.356, p = <.001). A negative correlation was also found between the increase in the Generalised Anxiety Disorder 7 score and the decrease in the International Index of Erectile Function score (r = −0.200, p = .012). One of the main factors post‐COVID‐19 erectile dysfunction is anxiety and depression due to the disease.

Comparative evaluation of relaxant effects of three prangos species on mouse corpus cavernosum: Chemical characterization and the relaxant mechanisms of action of P. pabularia and (+)-oxypeucedanin

ETHNOPHARMACOLOGICAL RELEVANCE

Erectile dysfunction (ED) is the most common form of sexual dysfunction which has been the topic of great interest through the history by all cultures. It is now among the most treated health problems in men of all ages that develop under the influence of lifestyle factors and some diseases. Plants are extensively used to cure sexual dysfunction for centuries. Roots of Prangos sp. have been used to improve sexual performance in Anatolian traditional medicine and are rich of coumarin, furanocoumarin and their derivatives. Scientific research is necessary to support and validate the ethno-traditional uses of these plants.

AIM OF THE STUDY

The aim of this study is to investigate the effects of the root extracts of P. pabularia, P. uechtritzii and P. heyniae on erectile function and to isolate and identify the chemical compounds of the most active extract and reveal possible pharmacological mechanism of the major compound of the extract with the strongest relaxant effect in mouse corpus cavernosum (MCC).

MATERIALS AND METHODS

The roots of plants were extracted with chloroform, n-hexane and methanol. The compounds were isolated from the extract by column chromatography and structures were identified by NMR and MS. The relaxant effects of extracts (10^-7-10^-4 g/mL), (+)-oxypeucedanin (10^-7-10^-4 M) and Na₂S (10^-7-3 × 10^-3 M) were tested in MCC strips by DMT myograph. To investigate the mechanism, the synthesis inhibitors of aminooxyacetic acid (AOAA, 10^-2 M) and nitro-L-arginine methyl ester (L-NAME, 10^-4 M) were used, respectively. H₂S formation was evaluated basal and L-cysteine (L-cyst)-stimulated conditions by H₂S microsensor.

RESULTS

All extracts relaxed MCC in a concentration dependent manner. The maximum relaxing effects were achieved with chloroform extracts. Chloroform extract of P. pabularia (Pp-CE) was more potent than the others. Pp-CE-induced relaxations were significantly decreased by AOAA and L-NAME. (+)-Oxypeucedanin, the major compound of Pp-CE, induced relaxant responses and this effect was inhibited by AOAA, but not L-NAME. The relaxation of (+)-oxypeucedanin was found to be similar in view of E_max to positive control H₂S donor Na₂S. (+)-Oxypeucedanin increased L-cyst-stimulated H₂S formation. Augmentation of H₂S synthesis with (+)-oxypeucedanin was inhibited by AOAA.

CONCLUSIONS

Pp-CE has the strongest effect on relaxation of MCC and this result supports the traditional aphrodisiac use of P. pabularia root extract in Anatolia. The pharmacological mechanisms of Pp-CE to relax MCC involve NO and H₂S formation. (+)-Oxypeucedanin could be responsible for the H₂S-mediated relaxations of Pp-CE in MCC.

Pathological Significance of Macrophages in Erectile Dysfunction Including Peyronie's Disease

Erectile function is regulated by complex mechanisms centered on vascular- and nerve-related systems. Hence, dysregulation of these systems leads to erectile dysfunction (ED), which causes mental distress and decreases the quality of life of patients and their partners. At the molecular level, many factors, such as fibrosis, lipid metabolism abnormalities, the immune system, and stem cells, play crucial roles in the etiology and development of ED. Although phosphodiesterase type 5 (PDE5) inhibitors are currently the standard treatment agents for patients with ED, they are effective only in a subgroup of patients. Therefore, further insight into the pathological mechanism underlying ED is needed to discuss ED treatment strategies. In this review, we focused on the biological and pathological significance of macrophages in ED because the interaction of macrophages with ED-related mechanisms have not been well explored, despite their important roles in vasculogenic and neurogenic diseases. Furthermore, we examined the pathological significance of macrophages in Peyronie’s disease (PD), a cause of ED characterized by penile deformation (visible curvature) during erection and pain. Although microinjury and the subsequent abnormal healing process of the tunica albuginea are known to be important processes in this disease, the detailed etiology and pathophysiology of PD are not fully understood. This is the first review on the pathological role of macrophages in PD.

Nuts: Natural Pleiotropic Nutraceuticals

Common nuts (tree nuts and peanuts) are energy-dense foods that nature has gifted with a complex matrix of beneficial nutrients and bioactives, including monounsaturated and polyunsaturated fatty acids, high-quality protein, fiber, non-sodium minerals, tocopherols, phytosterols, and antioxidant phenolics. These nut components synergize to favorably influence metabolic and vascular physiology pathways, ameliorate cardiovascular risk factors and improve cardiovascular prognosis. There is increasing evidence that nuts positively impact myriad other health outcomes as well. Nut consumption is correlated with lower cancer incidence and cancer mortality, and decreased all-cause mortality. Favorable effects on cognitive function and depression have also been reported. Randomized controlled trials consistently show nuts have a cholesterol-lowering effect. Nut consumption also confers modest improvements on glycemic control, blood pressure (BP), endothelial function, and inflammation. Although nuts are energy-dense foods, they do not predispose to obesity, and in fact may even help in weight loss. Tree nuts and peanuts, but not peanut butter, generally produce similar positive effects on outcomes. First level evidence from the PREDIMED trial shows that, in the context of a Mediterranean diet, consumption of 30 g/d of nuts (walnuts, almonds, and hazelnuts) significantly lowered the risk of a composite endpoint of major adverse cardiovascular events (myocardial infarction, stroke, and death from cardiovascular disease) by ≈30% after intervention for 5 y. Impressively, the nut-supplemented diet reduced stroke risk by 45%. As they are rich in salutary bioactive compounds and beneficially impact various health outcomes, nuts can be considered natural pleiotropic nutraceuticals.

Dietary Antiplatelets: A New Perspective on the Health Benefits of the Water-Soluble Tomato Concentrate Fruitflow®

Our understanding of platelet functionality has undergone a sea change in the last decade. No longer are platelets viewed simply as regulators of haemostasis; they are now acknowledged to be pivotal in coordinating the inflammatory and immune responses. This expanded role for platelets brings new opportunities for controlling a range of health conditions, targeting platelet activation and their interactions with other vascular cells. Antiplatelet drugs may be of wider utility than ever expected but often cause platelet suppression too strong to be used out of clinical settings. Dietary antiplatelets represent a nutritional approach that can be efficacious while safe for general use. In this review, we discuss potential new uses for dietary antiplatelets outside the field of cardiovascular health, with specific reference to the water-soluble tomato extract Fruitflow^®. Its uses in different aspects of inflammation and immune function are discussed, highlighting exercise-induced inflammation, mediating the effects of air pollution, and controlling thrombotic aspects of the immune response. Potential future developments in women’s health, erectile dysfunction, and the allergic response indicate how broad the utility of dietary antiplatelets can be.
