A potential treatment for erectile dysfunction: Effect of platelet-rich plasma administration on axon and collagen regeneration in cavernous nerve injury.

Recent studies highlighted the role of platelet-rich plasma (PRP) in progenitor cell homing, migration, and nerve cell regeneration while also inhibiting fibrosis and apoptosis in cavernous nerve injury (CNI). The aim of this study was to investigate the effect of PRP administration on axon and collagen regeneration in CNI. A true experimental study using a post-test-only control group design was conducted. Twenty-five male Wistar rats (Rattus norvegicus), weighing 200-300 grams, were divided into five groups: two control groups (sham procedure and negative control), and three experimental groups receiving local PRP, intraperitoneal PRP, and a combination of local and intraperitoneal PRP. The cavernous nerve was injured with a hemostasis clamp for one minute before 200 µL of 200 PRP was injected locally, intraperitoneally, or both, depending on the group. After four weeks, the rats were euthanized, tissue segments (2 mm) from each cavernous nerve and mid-penis were collected and analyzed for collagen density, axon diameter, and number of myelinated axons. Our study found that collagen growth was slower in CNI group without PRP (sham procedure) compared to all PRP groups (local, intraperitoneal, and combination). The intraperitoneal PRP group had the highest collagen density at 5.62 µm; however, no significant difference was observed in collagen density among all groups (p=0.056). Similar axon diameter was found across the groups, with no statistically significant difference observed (p=0.856). In the number of myelinated axons, a significant difference was found among all groups with significantly more axons in local PRP and combined local and intraperitoneal PRP groups compared to others (p=0.026). In conclusion, PRP administration improved the number of myelinated axons in CNI, suggesting PRP role in CNI regeneration and the potential for an innovative approach to treating erectile dysfunction associated with CNI.

Forensic application of sandpaper spray ionization mass spectrometry (SPS-MS): Direct analysis of solid pharmaceutical formulations and edible cannabis products.

In this work, we employed a new ambient ionization mass spectrometry technique, sandpaper spray mass spectrometry (SPS-MS), as an efficient tool to analyze pills and tablets of pharmaceutical formulations. The following samples were analyzed: regulators of blood pressure, cholesterol, and diabetes, and drugs for the treatment of erectile dysfunction (ED). Additionally, a hard candy of Cannabis sativa containing Δ9-tetrahydrocannabinol (Δ9-THC) and its related isomer cannabidiol (CBD) was also evaluated. The surfaces of the samples, without any prior treatment, were sanded onto triangular-cut sandpaper, and full MS scans (and MS/MS) were acquired in both positive and negative ionization modes. SPS-MS (and MS/MS) allowed for prompt detection of the active pharmaceutical ingredients (APIs) in each formulation. Other components of the formulations, added as excipients, were also tentatively identified. The results described herein indicate that the SPS-MS technique can be applied to fast screening of pills and tablets being potentially used as an efficient tool to detect counterfeit pharmaceutical and illicit products, a current issue of increasing concern.

Treatment of erectile dysfunction by intracavernosal administration of mesenchymal stem cells in patients with diabetes mellitus.

The purpose of study is to assess and analyse the effectiveness of their use in the treatment of erectile dysfunction in patients with diabetes mellitus. The literature search was conducted using systematic methods and analysis in databases such as Web of Science, Scopus, PubMed, Elsevier, and Springer, with 41 sources included for further review. The study highlights microangiopathic and neuropathic links as key factors in erectile dysfunction development in diabetic patients, stemming from endothelial dysfunction and conductivity disturbances. Mesenchymal stem cell therapy from bone marrow, adipose tissue, and umbilical cord mitigates pathogenic impact through regenerative and anti-apoptotic effects. Due to this, most studies indicate high efficacy of the treatment and rapid therapeutic action through intracavernosal administration. Some studies suggest an increase in the body's receptor sensitivity to other drugs, such as sildenafil. From the perspective of further research on this issue, standardising the preparation of stem cells and the treatment method using a large sample size is essential to introduce such a method as an extremely promising therapy for this delicate issue in men into practical medicine. The practical value of the study lies in the systematisation of information on different sources of mesenchymal stem cells for treating erectile dysfunction.

Erectile dysfunction among male patients receiving methadone maintenance treatment: focusing on anxiety-related symptoms.

Erectile dysfunction (ED) in patients receiving methadone maintenance treatment (MMT) is a relatively neglected issue. In this study we sought to determine the actual prevalence of ED and risky sexual behaviors in patients receiving MMT and identify clinically relevant risk factors for ED, particularly mental health conditions, that may contribute to achieving holistic healthcare and improving treatment adherence in this patient population. A cross-sectional study of male Chinese MMT patients was conducted. Comprehensive demographic and clinical data regarding age, obesity, history of major mental and physical illness, HIV infection, other substance use, methadone dose/duration, and associated risky sexual behaviors were all collected. Assessment tools, including the 5-item International Index of Erectile Function, the Chinese Health Questionnaire, and the Taiwanese Depression Questionnaire were administered. The relationship between mental health-related factors and ED was fully analyzed and elaborated. The prevalence of ED among male patients in a methadone maintenance therapy outpatient clinic was 55.7%. The prevalence rate of ED among the individuals treated for longer than 6months was 56.8%, whereas that for untreated individuals was 52.0%. Additionally, methadone-treated individuals were older and had a higher proportion of condom use and drug-assisted sexual activity than untreated individuals. Pearson correlation revealed that higher Chinese Health Questionnaire and Taiwanese Depression Questionnaire scores were negatively correlated with lower scores on the 5-item International Index of Erectile Function. In the multivariate regression model, anxiety and other psychosomatic symptoms were associated with more severe ED, whereas individuals who consumed alcohol within the past month had less severe ED after adjustment for other demographic and clinical variables. The findings of the present study revealed no association between ED and methadone treatment duration or dosage. Healthcare professionals should discuss mental health issues in patients on MMT with ED, especially anxiety symptoms and recent alcohol use. This study is one of the few reports within the limited body of research highlighting a significant association of ED with anxiety-related symptoms in patients undergoing MMT. Our study had some limitations. First, the sample size of HIV-infected individuals was insufficient. Second, the cross-sectional study design could not definitively demonstrate a causal mechanism. In patients undergoing MMT, individuals who reported less severe anxiety symptoms and alcohol consumption in the past month tended to have less severe ED, regardless of the MMT duration or dosage.

THE ANALYSIS STUDY OF EFFECTIVENESS AND SAFETY OF ORAL SILDENAFIL CITRATE FOR TREATMENT OF ERECTILE DYSFUNCTION : A COMPREHENSIVE SYSTEMATIC REVIEW

Background: Erectile dysfunction (ED) is a medical condition affecting men's sexual performance and well-being. Sildenafil citrate, a specific inhibitor of phosphodiesterase type 5, is approved for treating ED. The efficacy and safety of oral sildenafil citrate in treating ED are crucial for successful treatment procedures. Understanding the relationship between the efficacy and safety of oral sildenafil citrate can help develop successful treatment procedures for ED patients. Methods: This systematic review adhered to the PRISMA 2020 guidelines and primarily examined entire English literature published between 2000 and 2024. Only editorials and review articles published in the same publication as the submission were accepted if they possessed a Digital Object Identifier (DOI). A variety of online platforms, including ScienceDirect, PubMed, and SagePub, were utilized to gather the relevant literature. Result: The study analyzed more than 2000 papers from reputable sources such as Science Direct, SagePub, and PubMed. After deciding to subject eight publications to additional inspection, a thorough evaluation of the entire body of literature was carried out. Conclusion: Sildenafil, a potent treatment for erectile dysfunction (ED), has been found to be effective in improving men's psychosocial aspects. It is an inhibitor of PDE5, a condition that affects men's emotional well-being. The study also found that the firmness of erections was linked to improvements in psychosocial aspects. Sildenafil can be used interchangeably with tablets, providing a convenient alternative for those with difficulty swallowing. However, follow-up for men with ED is often inadequate due to improper doses and lack of understanding.

Aerobic Exercise: Randomized Controlled Trial Data Suggest Qualified Benefits for Erectile Dysfunction.

Erectile dysfunction (ED) refers to the difficulty in achieving and maintaining a degree of penile erection that suffices for satisfactory sexual activity. ED is multifactorial in origin; its prevalence therefore varies with the population studied. In the general population, ED is present in 18-52% of men in younger to older age groups and in 43-76% of men with different medical conditions. Phosphodiesterase-5 inhibitor drugs are gold standard treatments for ED. However, because many lifestyle disorders predispose to ED and because aerobic exercise is beneficial for these lifestyle disorders, aerobic exercise may be a possible intervention for ED. In this context, a recent systematic review and meta-analysis identified 11 randomized controlled trials (RCTs; pooled N = 1,147) of aerobic exercise vs nonexercising control conditions for the treatment of ED. These RCTs had been conducted in men with different medical and surgical conditions, commonly obesity, metabolic syndrome, diabetes mellitus, and cardiovascular disease. The exercise interventions were varied but mostly involved 30-60 minutes sessions of activity, 3-5 times a week, for a median duration of 6 months. Advice for diet and weight loss was also commonly provided. The meta analysis found that aerobic exercise was significantly superior to nonexercising control conditions, with greater improvement in erectile functioning observed in subjects with greater baseline impairment. Limitations of the findings were that subjects could not be blinded to the nature of the intervention and that the magnitude of benefit with exercise, although statistically significant, fell below thresholds suggested for clinical significance. Aerobic exercise might therefore be more useful for the primary prevention of ED, for which preliminary evidence already exists. Exercise can also be recommended, along with other lifestyle guidance, to improve sexual functioning in both men and women and to improve health across a range of domains.

Role of the Triglyceride-Glucose Index as a Predictor of Therapeutic Response to Tadalafil in Patients With Erectile Dysfunction.

The triglyceride-glucose (TyG) index is an easily calculable indicator of endothelial dysfunction. We aimed to evaluate the effect of the TyG index on treatment response in patients using tadalafil for the treatment of erectile dysfunction (ED). The data of patients who used tadalafil for ED in our urology clinic between January 2018 and January 2023 were reviewed. The patients completed the 5-item International Index of Erectile Function (IIEF-5) questionnaire before treatment and in the 3rd month of treatment. Response to tadalafil treatment was accepted as an increase in IIEF category. Patients were divided into 2 groups according to treatment response. Factors affecting response to treatment were evaluated with a multivariate analysis. Of the 134 patients included in the study, 99 (73.3%) responded to tadalafil treatment. Mean age and body mass index (BMI) of the patient group responding to treatment were significantly lower than in the untreated group. The rates of diabetes mellitus (DM) and metabolic syndrome (MetS) were significantly lower in the group responding to treatment. Fasting glucose, triglyceride and total cholesterol values were significantly lower in the group responding to treatment than in the treatment-resistant group. The TyG index was 130.0 (102.0-180.0) in the group responding to treatment and 245.0 (182.0-320.0) in the treatment-resistant group (p=0.001). In the multivariate analysis, age, BMI, DM, MetS, and TyG index were affecting treatment response. A high TyG index negatively affects the response to treatment in patients using tadalafil for ED. In addition, age, BMI, presence of DM and MetS are other factors affecting the response to treatment.

Interrogating erectile dysfunction and evaluating novel therapeutic frontiers, with emphasis on stem cell strategies.

Male infertility arises from a complex interplay of factors affecting reproductive organs and various physiological pathways. Among these, erectile dysfunction (ED), a widespread global issue, plays a key role. While existing ED treatments address some aspects, achieving complete reversibility and avoiding side effects remains a challenge. In this context, stem cell therapy emerges as a promising, potentially transformative approach. Preliminary evidence from preclinical animal models and clinical trials highlights stem cell therapy's remarkable efficacy and effectiveness for ED. This novel strategy offers several advantages, including enhanced effectiveness and a reported absence of adverse side effects. This review delves into the causes of male infertility, with a particular focus on ED and its pathophysiology. We explore the current treatment landscape, highlighting therapy's existing strategies' limitations and stem cell therapy's unique potential. By examining relevant preclinical and clinical studies, we provide a comprehensive picture of this innovative approach and its promising future in restoring men's fertility and quality of life.

Carvacrol prevents D-( +)-galactose-induced aging-associated erectile dysfunction by improving endothelial dysfunction and oxidative stress in rats.

Aging is one of the risk factors involved in the development of erectile dysfunction (ED). Growing evidence suggests that oxidative stress is the critical mediator of changes in endothelial function and penile vascular tone in the aging process. Thus, reducing reactive oxygen species (ROS) levels may preserve the bioactivity of the penile vasculature. Antioxidant compounds, such as carvacrol, limit the damage caused by ROS and, therefore, benefit the treatment of ED. Thus, this study aims to evaluate the effects of carvacrol on ED using the D-( +)-galactose aging model. The animals were divided into five groups: control, D-( +)-galactose 150mg/kg, carvacrol 50mg/kg or 100mg/kg, and sildenafil 1.5mg/kg treated daily for 8weeks. The physiological, functional, and morphological characteristics of aging-associated ED were evaluated after treatment with carvacrol. Carvacrol prevented ED in a D-( +)-galactose-induced aging model by reducing hypercontractility, enhancing endothelial dysfunction in the rat corpus cavernosum, and improving endothelial health of rat cavernous endothelial cells. In addition, carvacrol prevented the destruction of erectile components essential for penile erection and promoted a reduction of penile tissue senescence, probably through mechanisms that involve the harmful modulation of oxidative stress. Carvacrol significantly improved the erectile function of rats in a D-( +)-galactose-induced aging model and has excellent potential as a new therapeutic alternative in treating erectile dysfunction.

Phosphodiesterase type 5 inhibitors as treatment for erectile dysfunction: a webinar-based poll unveiling perceptions of healthcare professionals.

Aim: Erectile dysfunction (ED) is marked by a recurring incapacity to achieve or uphold a satisfactory erection during sexual activities. The study aims to increase awareness about male reproductive health, dispel misconceptions about ED and encourage physician-patient discussions. Materials & methods: A live online poll was conducted during a 3-day webinar titled "Turning the Tide of Men's Health" organized by Viatris™ in collaboration with the Saudi Society of Family and Community Medicine and attended by healthcare professionals (HCPs) from diverse specialties. The attendees voluntarily responded to nine poll questions on adherence to ED medication, use of phosphodiesterase type 5 inhibitors (PDE5is) as cure versus management of ED and patients' challenges. The responses to the poll questions were recorded and assessed to understand the perceptions of HCPs. Results: The poll garnered 10,423 responses from 5831 attendees on the second day of the webinar. The key findings included HCPs' perceptions that PDE5is contribute to ED management not complete cure. The respondents acknowledged that adherence to ED medications might decline on days without planned sexual activity, and long-term adherence on a daily PDE5i is exhibited by a relatively modest percentage of ED patients. The consensus among respondents was that PDE5is do not enhance or generate sexual desire, and the daily schedule of ED treatment may be burdensome for some patients. Conclusion: The findings from this poll offer insights into the perspectives of HCPs regarding the usage of PDE5is to treat ED. Responders of the poll generally agreed that PDE5is can help manage ED without affecting desire, though adherence may be lower on days without planned sexual activity. Furthermore, most respondents acknowledged that adhering to a daily pill regimen posed a greater burden than waiting for the medication to take effect.

The I-Guana Shot Protocol, An Intracavernosal Application of Wharton's Jelly Stem Cells for the Treatment of Erectile Dysfunction, Phase II Study

Umbilical cord has become an increasingly used source of mesenchymal stromal cells for preclinical and, more recently, clinical studies. Different clinical uses on multiple anatomical structures have demonstrated the safe use of the umbilical cord tissue and derivates with multiple potentially different options to treat difficult diseases or clinical conditions. Immunophenotypic analysis and characterization of stem cells isolated from Wharton’s jelly via various methods is currently underway in clinical research. Stem cells are the body’s basic cells from which all other cells with specialized functions are generated. Under the right conditions in the body or perinatal environment, stem cells divide to form more new cells. These new cells become stem cells (self-renewal type of cells), and can also become specialized cells (differentiated) with more specific functions, such as blood cells, brain cells, heart muscle, urinary and genital tract, bone, etc. No other cell in the body has the natural ability to generate new cell types as stem cells do. As with any emerging scientific/medical field having such incredible potential, numerous research trials and data gathering efforts are currently being conducted world-wide. New data is being reported daily that present compelling cases for therapies using certain pathologies on selected patients. Scientists have been working for decades to harness the regenerative “power” of stem cells for the possible repair and rejuvenation of certain organs to activate tissue regeneration. The ultimate objectives of all these studies are the same: deliver transformative therapies. The capacity for these cells to transform into whatever cells or tissues that the body may need to regenerate itself could, within the next 3 generations, potentially provide the means to successfully treat blindness, spinal cord injuries, diabetes, cystic fibrosis, muscular dystrophy, or even erectile dysfunction in affected patients. Such future outcomes may be possible for candidate patients who are fortunate enough to have access to those scientific and evidence- based medical protocols that use such potent biological sources. It is vital that, in the light of the dazzling potential, mesenchymal stem cells research and medical applications continue, especially for compassionate medical use (e.g. for No Option patients).

Global research trends on the links between prostate cancer and erectile dysfunction between 2003 and 2023: A bibliometrics and visualized study

BackgroundThe incidence of prostate cancer (PC) has increased in recent years. Erectile dysfunction (ED) after prostate cancer treatment has aroused extensive attention. Bibliometric analysis was designed to investigate a systematic understanding of developments between PC and ED during the past 20 years. MethodsLiteratures on PC and ED were retrieved from the Web of Science Core Collection database (WoSCC). By using the VOS viewer and CiteSpace software to analysis the metrics of bibliometric literature, such as number of articles, journals, countries, institutions, authors, keywords and associated information. The number of publications per year was statistically analysed and plotted thorough Microsoft Office. In addition, Pajek software was used to adjust the visual map. ResultsA total of 2332 screened articles were included in the analysis. The Journal of Sexual Medicine, ranking first among the analysed journals, published 235 articles. The United States and Canada were leaders in PC and ED research. There is a need to strengthen inter-agency cooperation in this area of research on a global scale. Mulhall JP, as the most prolific author in this area of research, published 80 articles. And Rosen RC was the author with the most co-citated (693 co-citated). The main research focus on the prevention, treatment and management of ED after PC treatment in this field through the keyword analysis. ConclusionsResearch on PC and ED is expected to expand further worldwide. We found ED, as new sustainable treatment modalities, scientific postoperative management and psychological interventions for patients, may become the research hotspots and should be closely concerned in this study.

The Efficacy of Mediterranean Diet for Erectile Dysfunction in Diabetes Mellitus Patients: A Narrative Review

Background : Male infertility affects millions globally, with 12-15% of Indonesian couples facing conception challenges, 50% of which are attributed to male factors. Despite extensive research, 70% of male infertility cases remain idiopathic. Diabetes, a prominent factor in male infertility, affects 9.3% of the global population, with projections estimating 700 million cases by 2045. Recent studies suggest the Mediterranean diet positively impacts semen parameters, particularly in diabetic individuals. This review aims to explore the Mediterranean diet's effects on fertility in male diabetic patients. Reviews : The literature review employed three databases, focusing on in-vitro, in-vivo, pre-clinical, and clinical studies from 2014-2024. Diabetes, a chronic disease characterized by abnormal blood sugar levels, affects insulin production or effectiveness, leading to complications if left uncontrolled. Erectile dysfunction (ED), prevalent in diabetic men, is attributed to nerve and blood vessel damage from high blood sugar levels. Treatments for ED include PDE5 inhibitors, but alternative plant-based therapies are being explored. Platelet-rich plasma (PRP) has shown promise in animal studies but lacks human trial data. The Mediterranean diet, rich in plant-based foods and healthy fats, may help prevent sexual function deterioration in diabetic individuals. Comprehensive nutrition education and government efforts are crucial in promoting healthy lifestyles and ensuring access to fresh foods. Summary : In conclusion, the Mediterranean diet shows promise as a dietary intervention for improving male fertility in diabetic populations. Further research is warranted to confirm these findings and to explore the mechanisms underlying the effects of the Mediterranean diet on male fertility.

Patient out-of-pocket costs for guideline-recommended treatments for erectile dysfunction: a medicare cost modeling analysis.

Patient out-of-pocket (OOP) cost represents an access barrier to erectile dysfunction (ED) treatment. We determined OOP cost for men with ED covered by Fee-for-Service Medicare. Coverage policies were obtained from the Medicare Coverage Database for treatments recommended by the 2018 American Urological Association (AUA) guidelines. OOP cost was retrieved from the 2023 Centers for Medicare & Medicaid Services Final Rule. OOP cost for treatments without Medicare coverage were extracted from GoodRx® or literature and inflated to 2022 dollars. Annual prescription costs were calculated using the published estimate of 52.2 yearly instances of sexual intercourse. Medicare has coverage for inflatable penile prostheses (IPP; strong recommendation), non-coverage for vacuum erection devices (VED; moderate recommendation) and phosphodiesterase type-5 inhibitors (PDE5i; strong recommendation), and no policies for intracavernosal injections (ICI; moderate recommendation), intraurethral alprostadil (IA; conditional recommendation), or low-intensity extracorporeal shock wave therapy (ESWT; conditional recommendation). Annual IA prescription is most costly ($4022), followed by ICI prescription ($3947), one ESWT course ($3445), IPP ($1600), PDE5i prescription ($696), and one VED ($213). PDE5i and IPP, both strongly recommended by AUA guidelines, are associated with lower OOP cost. Better understanding of patient financial burden may inform healthcare decision-making.

Molecular Docking Approach to Identify Flavonoids as Potential Phosphodiesterase 5 Inhibitors for Erectile Dysfunction Treatment

An erection that is not strong enough for sexual activity might be caused by erectile dysfunction. Periodically experiencing difficulties achieving an erection is not always a reason for alarm. On the other hand, if erectile dysfunction persists, it may lead to stress, undermine confidence, and exacerbate interpersonal issues. In addition to being a risk factor for heart disease, difficulties achieving or maintaining an erection may also indicate an underlying medical issue that needs to be treated. Many studies have also steadily examined flavonoids' capacity to inhibit the phosphodiesterase 5 enzyme in several recent studies. This is an enzyme expressed in erectile tissue that is the most important substance that degrades cGMP in the body's smooth muscle cells. This study identified two prominent flavonoids that had inhibitory effects on the phosphodiesterase 5 enzyme: Amenoflavone and Umbralisib. Our research suggests new molecular pathways by which these substances might influence biological processes. One compound that shows promise for treating erectile dysfunction and is safe for healthy cells is Amentoflavone.

Penile prosthesis for erectile dysfunction in France: A six-year nationwide database analysis

IntroductionUrological consultations for erectile dysfunction (ED) are increasing worldwide. Penile prosthesis (PP) implantations are performed when other treatments are unsuccessful. However, there is no data regarding PP implantations in France beyond the year 2016. ObjectivesThis study aimed to describe the changes in the number and type of PP implants used for the treatment of ED in France from 2016 to 2021 and the hospitalization rates following implantation using French national data from the Program for the Medicalization of Information Systems (PMSI). Materials and methodsWe analyzed data on PP implantations in all France hospitals. PPs were coded into three types according to the Common Classification of Medical Procedures (CCAM). The number of patients admitted to hospital with complications twelve months after implantation was also recorded. ResultsDuring the study period, 3675 men received 3868 PPs in France. A gradual increase in the total number of implanted PPs was observed, with an overall increase of 33.8%. In 2020, there was a sharp decline in the number of implanted PPs, primarily owing to the COVID-19 pandemic. The most commonly used implant was PPs with an extracavernous compartment, comprising 85% of all PPs. Twelve months after implantation, only 1–2% of the patients were rehospitalized. ConclusionPP implantation surgeries are highly reproducible and have a low incidence of complications, in terms of rehospitalization after one year of placement (1.8%). Moreover, there was an increase in the demand for penile prosthesis implantations in France between 2016 and 2021. Level of evidence4: Descriptive epidemiological study.

Spontaneous erectile function recovery among young men with erectile dysfunction taking tadalafil 5mg once a day.

Daily (once a day [OaD]) tadalafil intake is a valuable option for men favoring spontaneous over scheduled sexual intercourse. The study sought to assess the rate of and the clinical factors associated with spontaneous, medication-free erectile function (EF) recovery after discontinuation of tadalafil 5mg OaD in a cohort of young men seeking first medical help for psychogenic erectile dysfunction (ED) as their primary complaint. Data from 96 consecutive patients <50years of age seeking first medical help for ED and prescribed tadalafil 5mg OaD were analyzed. Patients completed the International Index of Erectile Function (IIEF) and underwent baseline penile color Doppler ultrasound. Follow-up involved clinical assessments or phone interviews. Spontaneous medication-free EF recovery was defined as IIEF EF domain score >22 after tadalafil discontinuation, prompting cessation of follow-up. Descriptive statistics compared tadalafil OaD responders and nonresponders. Cox regression hazard models explored the association between baseline characteristics and EF recovery risk post-drug discontinuation. Kaplan-Meier analyses estimated EF recovery probability over time. The primary outcome was EF recovery after discontinuation of tadalafil 5mg OaD. Overall, median age was 39 (interquartile range [IQR], 32-45) years. Of all, 82 (85.4%) patients achieved EF recovery after tadalafil OaD discontinuation, while 14 (14.6%) patients were identified as nonresponders. Median tadalafil usage time (from beginning to discontinuation) was 3 (IQR, 2-11) months. The most common treatment-emergent adverse event was headache in 9 (9.4%) patients. Nonresponders were older (43 [IQR, 42-45] years vs 38 [IQR, 31-44] years; P = .03), had higher body mass index (25.5 [IQR, 23.4-29.9] kg/m2 vs 23.6 [IQR, 21.8-25.9] kg/m2; P = .04), and reported lower baseline IIEF EF domain scores (12 [IQR, 7-15] vs 15 [IQR, 10-22]; P = .02) than responders. Nonresponders and responders did not differ in terms of baseline ED severity, Charlson comorbidity index, smoking, alcohol consumption, regular physical exercise, and color Doppler ultrasound parameters. Upon Cox regression analysis, younger age (hazard ratio, 0.95; 95% confidence interval, 0.92-0.99; P = .01) was associated to EF recovery, after adjusting for baseline ED severity, body mass index, smoking, and Charlson comorbidity index ≥1. The Kaplan-Meier analysis displays the probability of EF recovery over time, indicating rates of 43%, 60%, and 72% at 3-, 6-, and 12-month follow-up intervals, respectively. Tadalafil 5mg OaD is an effective short-term treatment for psychogenic ED, allowing its discontinuation after achieving a normal medication-free EF. The main limitations are the limited number of participants and the potential neglect of confounding factors. Almost 1 out of 2 young men with primary psychogenic ED who were prescribed with tadalafil 5mg OaD recovered spontaneous medication-free EF after 3months of treatment. Overall, the younger the patient was, the higher the chance there was of spontaneous EF recovery after drug discontinuation.

Unveiling the Hidden Perils: A Comprehensive Review of Fungal Infections in Inflatable Penile Prosthesis Surgery

Inflatable penile prosthesis (IPP) surgery is an effective treatment for erectile dysfunction (ED), but infections pose a significant threat to its success. Current guidelines lack antifungal recommendations, despite rising fungal infection rates post-IPP surgery. This review examines epidemiology, risk factors (including diabetes mellitus, immunosuppression, and obesity), and pathogenesis, highlighting the role of biofilm formation in device contamination. Clinical manifestations vary from acute to delayed, with fungal biofilms presenting challenges in diagnosis. Prophylactic strategies, including broad-spectrum antibiotics and antifungals, are crucial, with evidence suggesting a 92% reduction in infections. With fungal infections showing lower salvage rates, management involves culture-guided treatment, irrigation, and oral antibiotics. Future research aims to understand biofilm mechanisms and develop biomaterials to reduce infection rates. Implementing antifungal therapy, along with standard practices like the no-touch technique and antibiotic dips, is crucial in preventing IPP infections.
