Abstract
Inhibition of 5α-reductase (5αR), which blocks the conversion of testosterone to its active metabolite, dihydrotestosterone, has been shown to impact further prostate enlargement (benign prostatic hyperplasia, or BPH). Clinical trials of standardized lipidosterolic extracts of Serenoa repens (LSESr), also known as standardized extracts of saw palmetto, have demonstrated improvement in lower urinary tract symptoms (LUTS) and delayed progression of BPH. The aim of this preclinical study was to compare two standardized LSESr, a proprietary ultrahigh-pressure supercritical carbon dioxide extract of S. repens (UHP-sCESr) and the well-established hexanic extract of S. repens (HESr), for both 5αR inhibition activity and lipid profiles. UHP-sCESr and HESr had nearly identical inhibition curves and comparable IC50 values for 5αR-1 (9.25 ± 0.87 and 9.86 ± 0.11 μg/mL, respectively; p = 0.43) and 5αR-2 (7.47 ± 0.07 and 7.72 ± 0.05 μg/mL, respectively; p = 0.0544). UHP-sCESr and HESr also had comparable lipid profiles based on similar total fatty acid levels (87.7% and 91.5%, respectively), weight/weight comparisons of individual fatty acids, and individual fatty acid ratios to lauric acid. In addition, UHP-sCESr meets the standard set by the United States Pharmacopeia (USP) monograph for authenticity and purity for a supercritical carbon dioxide (SCCO2) extract of saw palmetto, whereas HESr meets the standard set by the European Medicines Agency (EMA) for a well-established medicinal product. In conclusion, based on enzyme inhibition curves and IC50 values, a standardized lipid profile is important to achieve comparable mechanisms of action for lipidosterolic extracts of saw palmetto. UHP-sCESr offers a comparable, standardized LSESr for men with LUTS/BPH in regions where the proprietary HESr is not available.

[PMID: 36498751 PMCID: PMC9736252 DOI: 10.3390/jcm11237169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/17/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022] Open
Abstract
The hexanic extract of Serenoa repens (HESr) has been in use for decades as an effective, safe and well-tolerated therapy for relieving bothersome lower urinary tract symptoms (LUTS) associated with benign prostate hyperplasia (BPH). This manuscript gives an overview of HESr as monotherapy for LUTS/BPH treatment and focuses on the currently available literature investigating the possible clinical benefits of HESr combination therapy with α-blockers. Combination therapy of HESr with α-blockers has been gaining significant interest in recent years, as an increasing body of evidence shows the beneficial pharmacological effects that HESr treatment can add to standard first-line treatment with α-blockers. By reducing persistent Prostatic Inflammatory Status (PIS), commonly present in LUTS/BPH patients, HESr complements the relaxation of prostate smooth muscle induced by α-blockers, thus providing additional symptom relief. Data suggest that patients harbouring PIS and having a specific clinical profile might especially benefit from the combination therapy. Future therapeutic efforts may take advantage of more personalised strategies for LUTS/BPH management.

Ejaculations and Benign Prostatic Hyperplasia: An Impossible Compromise? A Comprehensive Review. J Clin Med 2021; 10:jcm10245788. [PMID: 34945084 PMCID: PMC8704358 DOI: 10.3390/jcm10245788] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 12/03/2021] [Accepted: 12/08/2021] [Indexed: 01/23/2023] Open
Abstract
Background: Benign prostatic hyperplasia (BPH) is commonly responsible for lower urinary tract symptoms (LUTS) in men aged 50 or over. Sexual dysfunctions, such as ejaculatory disorders (EjD), go along with LUTS but are frequently overlooked in the initial evaluation. This review aimed to detail BPH-related EjD, as well as their modifications by medical, surgical, and interventional treatments. Methods: We conducted a narrative review looking for publications between 1990 and 2020, regarding physiopathology, epidemiology, evaluation, and therapeutic management (medical, surgical, and interventional) of BPH-related EjD. Results: Sixty-five articles were included in our final analysis. Forty-six percent of men presenting with LUTS reported EjD. If the prevalence increases with age and LUTS severity, the functional impairment is not correlated with age. Several self-questionnaires evaluated the sexual function, but only four approaches are specific to EjD. Medical therapies were exposed to anejaculation, rather than retrograde ejaculation (RE) (4–30% (alpha-blockers), 4–18% (5-alpha-reductase inhibitors)). Regarding surgical therapies, trans-urethral resection of the prostate (TURP) and incision of the prostate (TUIP) are associated with 50–70% and 21–35% of RE. The RE rate is important after open simple prostatectomy but can be reduced with robotic approaches and urethral sparing techniques (19%). Anatomic endoscopic enucleation of the prostate (AEEP) with or without a laser source is associated with an 11–36% RE rate, according to supramontanal preservation. Recent surgical techniques (Rezum©, Aquablation©, or Urolift©) were developed to preserve antegrade ejaculation with promising short-term results. Regardless of the surgical approach, anatomic studies suggest that the preservation of peri-montanal tissue (7.5 mm laterally; 10 mm proximally) is primordial to avoid post-operative RE. Finally, prostate artery embolization (PAE) limits the RE rate but exposes it to a 12 months 10% re-intervention rate. Conclusion: EjD concerns almost half of the patients presenting BPH-related LUTS. Initial evaluation of EjD impairment is primordial before medical or surgical therapy. Peri-montanal tissue preservation represents a key point for antegrade ejaculation preservation, regardless of the surgical option.

Glob Adv Health Med 2020; 9:2164956120973639. [PMID: 33294303 PMCID: PMC7705803 DOI: 10.1177/2164956120973639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 09/30/2020] [Accepted: 10/13/2020] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Nocturia is the most bothersome lower urinary tract symptoms (LUTS) and can significantly reduce men's quality of life. It is often poorly managed with conventional treatments. OBJECTIVE The purpose of this study was to evaluate the self-assessed benefits of a prostate health dietary combination formulation on mild LUTS, especially nocturia in healthy males. METHODS In an open label clinical study, thirty healthy male subjects with mild LUTS took one daily capsule of the product for 60 days. The primary outcome was self-assessed severity of LUTS using the International Prostate Symptoms Score (IPSS) questionnaire at Day 1 (baseline), Day 30 and Day 60. Safety and compliance were also evaluated. RESULTS At Day 60, IPSS significantly decreased from baseline by 16.3% (3.6 ± 2.1 vs. 4.3 ± 1.5, p < 0.05). Although the reduction in IPSS did not reach statistical significance at Day 30, it was mostly driven by a 30.7% decrease (p < 0.05) in the nocturia sub-score compared with baseline. While 37% of subjects reported at baseline waking up 2‒3 times/night to void, none did so after taking the study product for 60 days. Compliance was very high throughout the study. No adverse events related to the study product were reported. CONCLUSIONS The study product might be a safe alternative for individuals willing to explore a non-conventional approach to manage their nocturia. A larger randomized placebo-controlled clinical trial is warranted to confirm these results. Clinical trial registry: Clinical Trials.gov. Registration number (September 1st, 2016): NCT02886832.

Abstract
To investigate whether tamsulosin (TAM) and the hexanic extract of Serenoa repens (HESr) are more effective in combination than as monotherapy in men with moderate-to-severe lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). Subset analysis of data from a 6-month, multicenter observational study. Patients received either tamsulosin (0.4 mg/day) or HESr (320 mg/day) alone or in combination. Primary endpoints were change in symptoms and quality of life. Tolerability was also assessed. Seven hundred and nine patients were available for intention to treat (ITT) analysis, 263 treated with tamsulosin, 262 with HESr, and 184 with TAM + HESr. After 6 months, International Prostate Symptom Score (IPSS) scores improved by a mean (standard deviation) of 7.2 (5.0) points in the TAM + HESr group compared to 5.7 (4.3) points with TAM alone and 5.4 (4.6) points with HESr (p < 0.001). Quality of life showed greatest improvement with combination therapy (p < 0.02). Adverse effects were reported by 1.9% of patients receiving HESr, 13.3% receiving TAM, and 12.0% receiving TAM + HESr (p < 0.001). In men with moderate/severe LUTS/BPH, combination treatment with TAM + HESr produced more effective symptom relief and greater improvement in quality of life than with either treatment alone, with acceptable tolerability.

Abstract
Benign prostatic hyperplasia (BPH) is a noncancerous growth of the prostate. BPH commonly occurs in elderly men. Lower urinary tract symptoms (LUTS) secondary to BPH (LUTS/BPH) have significant impacts on their health. Saw palmetto (Serenoa repens) extract (SPE) has been evaluated for its effectiveness in improvement of LUTS/BPH at preclinical and clinical levels. Potential mechanisms of actions include anti-androgenic, pro-apoptotic, and anti-inflammatory effects. However, SPE efficacy was inconsistent, at least partly due to a lack of a standardized SPE formula. A hexane extract (free fatty acids, > 80%) provided more consistent results. Free fatty acids (lauric acid) were effective in inhibition of 5α-reductase, and phytosterol (β-sitosterol) reduced prostatic inflammation. Multiple actions derived from different constituents may contribute to SPE efficacy. Evaluation of the clinical relevance of these bioactive components is required for standardization of SPE, thereby enabling consistent efficacy and recommendations for the use in the prevention and treatment of BPH.

Abstract
OBJECTIVE To compare the efficacy and safety of oral supplementation with Serenoa repens (SR) and bovine colostrum (BC) plus tamsulosin (TAM) versus TAM alone over 12 months in men suffering from lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS Between February 2018 and February 2019, men with symptomatic BPH (IPSS ≥10) were prospectively recruited. This prospective, open-label, 12-month study included two different protocols: (1) group A, SR 320 mg/day + BC 30 mg/day + TAM 0.4 mg/day, and (2) group B, TAM 0.4 mg/day only. RESULTS Overall, 148 patients entered the study, 76 in group A and 72 in group B. At 12 months, the total IPSS had decreased by 5.5 with TAM + SR + BC and by 5.1 with TAM only (p = 0.21). However, when the total IPSS was divided into storage and voiding subscores, at 6 months the storage symptoms had improved significantly more with TAM + SR + BC (-1.6 vs. -0.9 with TAM only, p = 0.02), with the benefit persisting also at the 1-year evaluation (-1.8 vs. -0.8, p = 0.02). Moreover, the improvement in LUTS-related quality of life (QoL) was significantly different between the groups, with a mean decrease in IPSS QoL subscore of -2.5 ± 0.2 for TAM + SR + BC versus -1.8 ± 0.3 for TAM at 6 months (p = 0.04), and of -2.9 ± 0.4 for TAM + SR + BC versus -2.1 ± 0.4 for TAM at 12 months (p = 0.04). Conversely, no significant differences were found in maximal urinary flow rate (p = 0.38), postvoid residual volume (p = 0.12), prostate-specific antigen (p = 0.41), and prostate volume (p = 0.16). CONCLUSION Combination treatment with SR and BC plus TAM was shown to be more effective than treatment with TAM only in improving IPSS storage and QoL subscores in BPH patients after 6 months and up to 12 months of treatment.

Abstract
Objective: Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is re-ported in the literature ranging from 1 to 14.2%. The aim of the present study was to as-sess the impact on patient’s quality of life and symptoms of Flower pollen extract in asso-ciation with vitamins (Deprox 500®) in comparison with Serenoa repens 320 mg (Permix-on 320 mg® by Pierre Fabre) in patients with CP/CPPS. Methodology: All consecutive patients, with a diagnosis of CP/CPPS, referred to our center from January to August 2016, were screened to be enrolled in this single-center, random-ized, controlled trial. The main outcome measure was the evaluation of IPSS/NIH-CPSI (International Prostatic Symptom Score/NIH-Chronic Prostatitis Symptom Index) score variation and the assessment of the quality of life and symptoms at the end of the thera-py. The second outcome measure was the evaluation of the comorbidity role in the CP/CPPS therapy. 63 patients were analyzed; patients were randomized into two groups: 29 patients were treated with Deprox 500® 2 tablets/day for 6 weeks and 34 patients with Serenoa repens 320 mg, 1 tablet/day for 6 weeks. Results: The mean score variation for IPSS was -12.7 ± 4.3 in the Deprox 500® group and -7.8 ± 4.7 in the Serenoa repens group (p=0.0005) while for NIH-CPSI was -17.3±3.1 in the Deprox 500® group and -13.6±4.8 in the Serenoa repens group (p=0.0016). By ac-counting only the symptoms part of NIH-CPSI questionnaire, the mean score variation reported was -11.5±2.5 in the Deprox 500® group and -9.02±4.0 in the Serenoa repens group (p=0.009321). Furthermore, analyzing the comorbidity subgroups, in patients with hypertension, the mean IPSS score variation was -14.3±3.2 in the Deprox 500® group and -9.02±4.0 in the Serenoa repens group. Conclusion: In conclusion, in patients with CP/CPPS, Deprox 500® improves IPSS and NIH-CPSI scores up to 74.5% and 84.5% respectively. Furthermore, in patients with hypertension, the antioxidant effect of Deprox 500® reduces the mean IPSS score of 82.7%.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) attributed to benign prostatic hyperplasia (BPH) are common in men, considerably affecting quality of life. AIMS The self-directed use of over-the-counter (OTC) tamsulosin (0.4 mg) and potential safety risks were evaluated in an open-label, uncontrolled, exploratory, 8-week OTC-simulated study. METHODS Men (≥ 18 years) were recruited via mass advertising about bothersome LUTS. In a working retail environment, respondents reviewed the product and decided whether it was appropriate for them to use (self-selection phase). After purchasing the product, participants' ability to use it as directed by the proposed drug facts label (DFL) was assessed (home-use phase). RESULTS Of 1446 eligible men, 679 completed the self-selection phase, and 73.9% (502/679) self-selected to use tamsulosin correctly according to the DFL. Of 369 participants who purchased tamsulosin and entered the home-use phase, 321 took one or more doses of tamsulosin and participated in at least one telephone interview. In total, 85.4% (274/321) of participants adhered to the 'Stop Use' and 'Directions' instructions in the DFL. Overall, 139 (39.6%) participants experienced one or more adverse events (AEs); 65 (18.5%) were deemed drug-related, including dizziness (11 [3.1%]), ejaculation disorder (6 [1.7%]), and semen volume decrease (6 [1.7%]). No unexpected AEs were reported. CONCLUSIONS Of the men interested in self-managing their LUTS, a majority had moderate-to-severe LUTS of long duration. Most men were able to appropriately self-select and use tamsulosin in concordance with DFL instructions and directions. No unexpected AEs were reported during self-directed use. With further label refinement, an over-the-counter tamsulosin option might be feasible. TRIAL REGISTRATION ClinicalTrials.gov NCT01726270.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH), a common urological disease in aging men, frequently produces lower urinary tract symptoms (LUTS). Clinical studies have shown that terazosin relaxes the smooth muscle of the prostate and bladder, facilitates bladder emptying, improves LUTS, increases maximum urinary flow, and reduces the residual volume of urine. D-004, a lipid extract of the fruit of the Cuban royal palm (Roystonea regia), presents a similar efficacy to Saw palmetto. Clinical studies have demonstrated its efficacy and safety in short- and medium-term trials in patients with BPH. The objective of this study was to compare the efficacy and tolerability of D-004 with terazosin for 6 months on LUTS in patients with BPH. METHODS The present phase III study had an open, randomized, comparative design, with two parallel groups who received D-004 (320 mg/day) or terazosin (5 mg/day) for 6 months. The study included men at least 50 years of age, with evidence of the LUTS of moderate intensity according to the International Symptoms of the Prostate (IPSS). The effects on the IPSS Scale was the primary efficacy variable. The effects on the size of the prostate and the residual volume were secondary variables. The subjective self-perception of symptom relief at trial completion was a collateral outcome. Analysis was done by intention-to-treat. RESULTS The study included 100 men with a diagnosis of BPH, confirmed by digital rectal examination and ultrasonography, and moderate LUTS (IPSS score >7, <19). Baseline characteristics were similar in both groups. Nine patients did not continue the study: one from group D-004 (due to protocol violation) and eight from the terazosin group (six due to adverse events and two due to protocol violation; p < 0.01). D-004 and terazosin significantly reduced the IPSS scores at the end of the 6 months of therapy by 74.2% and 66.1%, respectively, with respect to baseline values. Comparisons between groups performed showed that, at the end of the treatment, D-004 was more effective (p < 0.05) than terazosin in reducing the IPSS score. Although the average size of the prostate was reduced in both groups, this reduction reached statistical significance only for D-004. On the other hand, postvoid residual volume was significantly and similarly reduced in both groups. Both treatments were safe, while D-004 was better tolerated than terazosin. CONCLUSIONS D-004 administered at a dose of 320 mg/day for 6 months showed comparable efficacy with terazosin (5 mg/day) in reducing the LUTS (IPSS score), producing a significant decrease in prostate volume and postvoid residual volume. Both treatments were safe, with better tolerability for D-004 as compared with terazosin.

Abstract
Phytosterols are one of the bioactive components responsible for the beneficial effects of Serenoa repens in Benign Prostate Hyperplasia. The aim of this study was to verify the actual variability of the phytosterols content in supplements containing serenoa, in order to provide useful elements to check the effectiveness of these preparations. The amount of campesterol, stigmasterol and β-sitosterol were determined by gas-chromatography in commercial raw materials and supplements containing serenoa in association or not with other botanicals. The experimental data were used to calculate amounts of phytosterols for recommended daily dose. The overall results of this study show an extreme variability in the content and also in the amounts per daily dose of phytosterols of the examined supplements (both mono/multi components). These data confirm that the characterization of serenoa based supplements is insufficient to ensure comparable effects between different products.

Abstract
OBJECTIVE To review the literature on the sexual adverse effects of pharmacological, instrumental and surgical treatments of lower urinary tract symptoms related to benign prostatic hyperplasia (LUTS/BPH). METHOD A non-systematic review of the scientific literature was conducted from the PubMed database to retrieve the most relevant scientific publications. A first research was cross-referenced with the results of literature reviews already published and enriched by the authors of this review. RESULTS AND CONCLUSION Sexual dysfunction and SBAU/BPH are intimately linked by a cross-over effect in the population of men over 50, a possible common pathophysiology and treatments for BPH with sexual consequences. Evaluating the sexuality of patients in care for SBAU/BPH is therefore essential. Patients should be informed of potential adverse drug effects of BPH, including ejaculation disorders with alpha blockers and loss of libido and erectile dysfunction with 5 alpha reductase inhibitors. After BPH surgery, loss of antegrade ejaculation is common, although preservation possibilities exist. The improvement of urinary function and the decrease of possible ejaculatory pains have a beneficial effect on the sexuality of the BPH patients operated. More rarely, patients may experience orgasmic dysfunction or even erectile dysfunction with a possible thermal effect on the vasculo-nerve bundles. LEVEL OF EVIDENCE Consensus d'experts.

Abstract
In this review, we focus on current trends in the management of male lower urinary tract symptoms (LUTS), defined here as LUTS, namely, storage, voiding, and post-micturition symptoms presumed secondary to benign prostatic hyperplasia (BPH), and discuss possible novel approaches toward better care. According to results of a PubMed database search covering the last 10 years and using keywords pertaining to male LUTS, this condition continues to be globally undiagnosed or diagnosed late, partly because of men's hesitation to seek help for perceived embarrassing problems or problems considered a normal part of aging. In addition, the prevalence of male LUTS is continually increasing because of a constantly aging population. Male LUTS can be bothersome and affect the quality of life (QoL) and sexual function. Additional effective alternatives for managing this condition need to be identified and incorporated into the current care model. Considering that most male LUTS such as frequency, hesitancy, urgency, and intermittency are easy to self-identify, a self-management approach toward male LUTS is proposed. Limited evidence supports the efficacy of phytotherapies and herbals as self-management options for male LUTS. However, introducing over-the-counter (OTC) medication with proven efficacy, accompanied by lifestyle and behavioral modifications, may be a promising approach that will encourage more men to treat their symptoms in a timely manner. Formal guidelines, along with appropriate education programs for patients and support from the healthcare community, will be needed to ensure that the promise of this approach is fully materialized.

Abstract
CONTEXT As an alternative approach, administration of phytotherapeutic agents in management of benign prostate hyperplasia (BPH), is rapidly growing each day. Different authors have indicated effectiveness of Viola odorata L. (Violaceae), Echium amoenum Fisch. & C.A.Mey. (Boraginaceae) and Physalis alkekengi L. (Solanaceae) in treatment of BPH. However, none have reported the beneficial outcomes of the mixture yet. OBJECTIVE This study evaluates the therapeutical effects of V. odorata, E. amoenum and P. alkekengi mixture on symptomatic BPH patients. MATERIALS AND METHODS Eighty six symptomatic BPH patients with International Prostate Symptom Score (IPSS) of more than 13 and prostate volume of more than 30 cm3 were randomly allocated to receive a two-week course of placebo (control group) or 1 mL of mixed hydro-alcoholic solution of P. alkekengi, E. amoenum and V. odorata extracts (1.5, 1 and 1.5% respectively) (treatment group). RESULTS IPSS score of incomplete urination (42.3 ± 2.04%), frequency of urination (20.08 ± 1.02%), intermittency (40.78 ± 2.16%), urgency (60.91 ± 3.14%), weak stream (50.58 ± 2.14%), straining (55.67 ± 2.53%) and nocturia (40.14 ± 1.89%) in treatment group were significantly decreased after treatment compare to placebo receiving group. Furthermore, the prostate volume (16.92 ± 0.89%) and extant urine volume (28.12 ± 1.36%) also significantly decreased in treatment group compared to control group. No significant side effects or abnormalities in biochemical tests and urinalysis were observed throughout the study. DISCUSSION AND CONCLUSIONS Based on results, mentioned mixture is safe and effective in improving life quality of patients suffering from BPH.

Clinically Meaningful Improvements in LUTS/BPH Severity in Men Treated with Silodosin Plus Hexanic Extract of Serenoa Repens or Silodosin Alone. Sci Rep 2017; 7:15179.

Abstract
To assess the rate and predictors of clinically meaningful improvements (CMI) in patients with lower urinary tract symptoms (LUTS) treated with either silodosin (SIL) alone or with a combination of SIL+ serenoa repens (Ser) hexanic lipidosterolic extract for ≥12 months. Data from 186 patients were collected. Patients completed the International Prostatic Symptoms Score (IPSS) at baseline and at follow-up assessment. Descriptive statistics and logistic regression models tested rates and predictors of CMI. Two CMI were assessed: 1) >3 points improvement in total IPSS from baseline to end (CMI#1); 2) >25% IPSS improvement from baseline to end (CMI#2). Overall, 93 (50%) patients were treated with SIL and SIL+ Ser, respectively. At a mean 13.5-mos follow-up [range: 12-20], mean IPSS scores were significantly lower in patients treated with SIL + Ser compared to those after SIL (p = 0.002). SIL + Ser patients more frequently achieved CMI#1 (69.9% vs. 30.1%, p = 0.001) and CMI#2 (68.8% vs. 31.2%, p < 0.001) compared SIL men. At multivariable analyses, younger age, IPSS severity and SIL + Ser (all p < 0.03) were independent predictors of CMI#1 and CMI#2. In conclusion, SIL + Ser therapy was more effective than SIL alone in improving IPSS scores in men with LUTS. SIL + Ser treatment led to CMIs in up to seven out of ten men.

Abstract
The nonhormonal medical treatment can be divided into empirical, when the cause has not been identified, and nonempirical, if the pathogenic mechanism causing male infertility can be solved or ameliorated. The empirical nonhormonal medical treatment has been proposed for patients with idiopathic or noncurable oligoasthenoteratozoospermia and for normozoospermic infertile patients. Anti-inflammatory, fibrinolytic, and antioxidant compounds, oligo elements, and vitamin supplementation may be prescribed. Infection, inflammation, and/or increased oxidative stress often require a specific treatment with antibiotics, anti-inflammatory drugs, and/or antioxidants. Combined therapies can contribute to improve sperm quality.

Abstract
In this review, results of randomized double-blind controlled clinical trials (RCTs) with extracts of Serenoa repens fruits at a dose of 320 mg/d for the treatment of lower urinary tract symptoms (LUTS) are assessed. Of the RTCs conducted for up to 6 months, a benefit was seen in three of three RTCs with ethanolic, in eight of nine RTCs with hexane, and in one of two RTCs with CO2 extracts. Of the RTCs conducted for more than 6 months, a benefit was seen in two RTCs with hexane and in one RTC with CO2 extracts, whereas one RTC with an ethanolic, two RTCs with hexane, and one RTC with CO2 extracts did not show positive results. As LUTS are dynamic conditions with strong spontaneous fluctuation over time, the majority of patients might expect improvement of single symptoms and thus of quality of life, particularly as the extracts are well tolerated even in long-term treatment.

Abstract
Benign prostate hyperplasia (BPH) is a high-incidence condition. Its diagnosis and treatment is shared between urologists and Primary Care physicians. Its management uses up a significant amount of resources. The Spanish Society of Primary Care Physicians (SEMERGEN), the Spanish Society of General Practitioners and Family Doctors (SEMG), the Spanish Society of Family and Community Medicine (semFYC), and the Spanish Association of Urology (AEU) have prepared a document on the management and monitoring of BPH, in which the aim is to incorporate the latest evidence in order to update the previously published guidelines, and present them here in condensed form. The main objective of these new recommendations is to raise the awareness of Primary Care physicians and assist them in its diagnostic evaluation, treatment and monitoring, as well as providing unified consensus criteria for referral to the secondary care level.

Abstract
The aim of this study is to establish the scientific benefit of royal jelly (RJ) on prostatic-specific antigen (PSA), post-void residual (PVR) volume and International Prostate Symptom Score (IPSS) in benign prostatic hyperplasia. For the study, a group of 40 men were administered 38 mg of RJ over a period of three months, their PSA values, prostate volumes and the volumes of their transitory prostate zones, PVR and IPPS values were measured at the end of the first month, and at the end of the third month. The results of this study confirm the potential of RJ in reducing PSA scores and improving IPSS values. Since the use of RJ did not lead to any significant reduction in PVR, prostate volume, or to any involution of the transitory zone, it appears that it may only affect the blood marker of prostatic hyperplasia and to improve quality-of-life (QoL) in those patients. Overall, in comparison to phytotherapy and conventional therapy, RJ had similar positive effects on QoL in patients with BPH, however it exhibited markedly better effects on reducing PSA levels in blood. The therapeutical use of RJ exhibited no side effects.

Abstract
Nocturia is an extremely common condition that has major sequelae for affected patients. Through disruption of sleep, nocturia impairs quality of life and worsens health outcomes, and is associated with a variety of morbidities including diabetes, coronary artery disease, obstructive sleep apnoea, obesity, metabolic syndrome, and depression. Unsurprisingly, several studies have also linked nocturia with reduced survival. Nocturia is not simply a consequence of lower urinary tract disease; rather, it is a multifactorial disorder that is often a manifestation of an underlying renal or systemic disease. Through the use of the frequency volume chart, clinicians can accurately quantify nocturia and determine its aetiology. Evaluation of quality of life and sleep using simple measures is essential in order to assess the impact of nocturia on a patient. Numerous treatment options for nocturia exist, but most are associated with minor benefit or lack sufficient evidence supporting their use. By systematically analysing an individual's causes of nocturia, clinicians can design appropriate treatment strategies to most effectively treat this condition.

Abstract
Objectives Lower urinary tract symptoms (LUTS) and sexual dysfunction (SDys) are common problems that affect quality of life (QOL) in elderly men. In addition to prescribed drugs, many over-the-counter medications including supplements are used to treat QOL diseases. Phosphodiesterase inhibitors are reported to be effective for both LUTS and SDys by increasing nitric oxide levels. French maritime pine bark extract Pycnogenol®, which is a potent nitric oxide donor, is reported to be effective for SDys. However, no reports have been published on whether it ameliorates LUTS. Design Open-labeled, randomized study. The effects of two supplements, Nokogiriyashi EX® containing 160 mg saw palmetto (SP) extract per tablet and Edicare® containing 10 mg of Pycnogenol®, 115 mg of l-arginine and 92 mg of aspartate (PAA) per tablet on International Prostate Symptom Score (IPSS), IPSS–QOL, Overactive Bladder Symptom Score (OABSS), International Index of Erectile Function 5 (IIEF5), Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), urinary 8-OHdG and uroflowmetry (UFM) of total 40 men with LUTS and SDys were examined. Results 19 subjects were instructed to take two tablets of SP, on the other 20 were on four tablets of PAA for 16 weeks. IPSS and IPSS–QOL showed statistically significant improvements in both groups. OABSS and IIEF5 were significantly improved in the PAA group. Conversely, ICIQ-SF, 8-OHdG and UFM did not change in either group. Conclusions PAA might be an effective therapeutic alternative for elderly patients with LUTS and SDys.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) is a disease affecting most of the elderly male. α1-blockers and 5-alpha reductase inhibitors are currently used to target lower urinary tract symptoms (LUTS). Moreover phytotherapeutic agents, including Serenoa Repens (SeR), have shown to have a role in ameliorating BPH/LUTS alone or in combination of other elements like Selenium (Se) and Lycopene (Ly). Areas covered: A literature review was performed using data from articles assessing the role of of SeR+Se+Ly in the management of LUTS secondary to BPH. Diverging evidence on SeR's efficacy is available. On one hand several studies have shown SeR efficacy in treating BPH/LUTS. SeR is effective in reducing prostate size, urinary frequency, dysuria, nocturia and in improving maximum urine flow-rate. On the other hand two long-term trials reported that SeR did not improve prostate size or urinary flow. SeR+Se+Ly in combination with tamsulosin is more effective than single therapies in improving IPSS and increasing maximal urinary flow-rate in patients affected by LUTS/BPH. Expert opinion: Despite great amount of preclinical and clinical studies, the use of SeR in BPH/LUTS is not sustained by clear evidence for a therapeutic efficacy but current data hint higher efficacy of of SeR+Se+Ly compared to SeR alone.

Abstract
BACKGROUND The nicotinamide adenine dinucleotide phosphate-dependent membrane protein 5α-reductase catalyses the conversion of testosterone to the most potent androgen - 5α-dihydrotestosterone. Two 5α-reductase isoenzymes are expressed in humans: type I and type II. The latter is found primarily in prostate tissue. Saw palmetto extract (SPE) has been used extensively in the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH). The pharmacological effects of SPE include the inhibition of 5α-reductase, as well as anti-inflammatory and antiproliferative effects. Clinical studies of SPE have been inconclusive - some have shown significant results, and others have not - possibly the result of varying bioactivities of the SPEs used in the studies. PURPOSE To determine the in vitro potency in a cell-free test system of a novel SP supercritical CO2 extract (SPSE), an inhibitor of the 5α-reductase isoenzyme type II. MATERIALS AND METHODS The inhibitory potency of SPSE was compared to that of finasteride, an approved 5α-reductase inhibitor, on the basis of the enzymatic conversion of the substrate androstenedione to the 5α-reduced product 5α-androstanedione. RESULTS By concentration-dependent inhibition of 5α-reductase type II in vitro (half-maximal inhibitory concentration 3.58±0.05 μg/mL), SPSE demonstrated competitive binding toward the active site of the enzyme. Finasteride, the approved 5α-reductase inhibitor tested as positive control, led to 63%-75% inhibition of 5α-reductase type II. CONCLUSION SPSE effectively inhibits the enzyme that has been linked to BPH, and the amount of extract required for activity is comparatively low. It can be confirmed from the results of this study that SPSE has bioactivity that promotes prostate health at a level that is superior to that of many other phytotherapeutic extracts. The bioactivity of SPSE corresponds favorably to that reported for the hexane extract used in a large number of positive BPH clinical trials, as well as to finasteride, the established standard of therapy among prescription drugs. Future in vitro and clinical trials involving SPEs would be useful for elucidating their comparative differences, as well as appropriate patient selection for their use.

Abstract
Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) are common clinical problems in urology and affect the majority of men at some time during their lives. The development of BPH/LUTS is associated with an increased ratio of estrogen to androgen levels, and this ratio, when mimicked in a variety of animals, induces BPH and lower urinary tract dysfunction (LUTD). While the precise molecular etiology remains unclear, estrogens have been implicated in the development and maintenance of BPH. Numerous endogenous and exogenous estrogens exist in humans. These estrogens act via multiple estrogen receptors to promote or inhibit prostatic hyperplasia and other BPH-associated processes. The prostate is an estrogen target tissue, and estrogens directly and indirectly affect growth and differentiation of prostate. The precise role of estrogen action directly affecting prostate growth and differentiation in the context of BPH is an understudied area and remains to be elucidated. Estrogens and selective estrogen receptor modulators (SERMs) have been shown to promote or inhibit prostate proliferation illustrating their potential roles in the development of BPH as therapy. More work will be required to identify estrogen signaling pathways associated with LUTD in order to develop more efficacious drugs for BPH treatment and prevention.

Abstract
Purpose To evaluate change in quality of life (QoL) and symptoms in patients with lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH) in conditions of current clinical practice. Methods Prospective, longitudinal, multicenter open-label study was carried out in urology outpatient clinics. Patients were ≥40 years of age with an International Prostate Symptom Score (IPSS) score ≥8. QoL and symptoms were measured at baseline and 6 months using the Benign Prostatic Hyperplasia Impact Index (BII) and the IPSS. Results 1713 patients were included for analysis. Mean (SD) IPSS and BII scores at baseline were 16.8 (5.4) and 6.8 (2.6), respectively. 8.9 % (n = 153) of study participants did not receive treatment (watchful waiting, WW), 70.3 % (n = 1204) were prescribed monotherapy (alpha-adrenergic blockers [AB]; phytotherapy [PT, of which 95.2 % was the hexanic extract of Serenoa repens, HESr]; or 5-alpha-reductase inhibitors [5ARI]), and 20.8 % (n = 356) received combined treatment (AB + 5ARI; AB + HESr; others). At 6 months, improvements in QoL were similar across the different medical treatment (MT) groups, both for monotherapy (AB: mean improvement [SD] of 2.4 points [2.4]; PT: 1.9 [2.4]; 5ARI: 2.5 [2.3]) and combined therapy (AB + 5ARI: 3.1 [2.9]; AB + PT: 3.1 [2.5]). There were no clinically significant differences between MT groups and all showed significant improvement over WW (p < 0.05). HESr showed similar efficacy to AB and 5ARI both as monotherapy and in combination with AB. Results on the IPSS were similar. Conclusions Improvements in QoL and symptoms were equivalent across the medical treatments most widely used in real-life practice to manage patients with moderate or severe LUTS. HESr showed an equivalent efficacy to AB and 5ARI with fewer side effects.

Abstract
The long-term intake of a judiciously composed nutriceutical containing low-dose vitamins, antioxidants, minerals and particular herbal preparations seems justified for older persons who take medication, or who consume an unbalanced diet, or who are exposed to environmental toxins. Recent reports suggest these nutriceuticals may delay age-related diseases and the occurrence of cancer, and reduce mortality in apparently healthy ageing men. Food supplementation with a nutriceutical that was formulated particularly for ageing men should result in an increase of at least one quality-adjusted life year and may lower the financial and social burden of disease in elderly people.

Abstract
The International Consultation on Urological Disease have recently published comprehensive conclusions, based on evidence reviewed by eight committees, on aspects of male lower urinary tract symptoms (LUTS). In this review, we summarise the conclusions from four of the committees, namely, the evidence regarding the epidemiology of male LUTS, patient assessment, nocturia and medical management. It is indisputable that with an expanding and ageing global population the prevalence of male LUTS is likely to increase. Therefore symptom prevention and preservation of quality of life (QoL) feature highly in the guidelines. There are now a number of different medical options, proven to lead to significant improvements in symptom scores, flow rate and QoL available to men with LUTS. Meta-analyses have shown the benefits for alpha blockers, antimuscarinics, 5-α reductase and phosphodiesterase-5 inhibitors. High level evidence also exists for combinations of all of the above with alpha blockers and so men with concomitant storage symptoms, prostate volume > 30 mL, PSA > 1.4 or erectile dysfunction may be considered for combination treatment of an alpha blocker with an antimuscarinic, 5-α reductase inhibitor or phosphodiesterase-5 inhibitor respectively. In an era of personalised medicine, appropriate patient selection is likely to provide the key to the most effective clinical management strategy.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) is a common disease among men and significantly impacts quality of life by causing lower urinary tract symptoms (LUTS). Current medical therapies are not always adequate in controlling LUTS or slowing disease progression, and there is unmet need for new effective therapeutic options. AREAS COVERED The authors review the standard current medical therapies for BPH which include the use of α-1 blockers, 5-α reductase inhibitors, combination therapy and PDE inhibitors. Following this, the authors then discuss new therapies that are currently undergoing preclinical and clinical investigation. EXPERT OPINION Existing preclinical and clinical trials have highlighted many promising therapies to treat BPH. Further investigation with larger clinical trials is needed to establish these drugs as standard therapies. As the number of drugs in the arsenal against BPH continues to grow, providers and patients will have to engage in a discussion that weighs the risks and benefits of each therapy.

Abstract
INTRODUCTION In Korea, increasing attention has recently been given to the use of phytotherapeutic agents to alleviate the symptoms of BPH. Serenoa repens has been shown to have an equivalent efficacy to Finasteride or Tamsulosin in the treatment of BPH in previous studies. The present study was designed to compare the efficacy and safety of Serenoa repens plus tamsulosin with tamsulosin only over 12 months in men with LUTS secondary to BPH. MATERIALS AND METHODS One hundred forty men with symptomatic BPH (IPSS≥10) were recruited in our hospital for a 12-month, open-label, randomized trial. Patients were randomly assigned to either tamsulosin 0.2 mg/day plus Serenoa repens 320 mg/day (n=60) or tamsulosin 0.2 mg/day only (n=60). Prostate volume and PSA were measured at baseline and at end-point, whereas total IPSS, and its storage and voiding subscores, LUTS-related QoL, Qmax, and PVR were evaluated at baseline and later every 6 months. RESULTS Total 103 patients were finally available: 50 in the TAM+SR group and 53 in the TAM group. At 12 months, total IPSS decreased by 5.8 with TAM+SR and 5.5 with TAM (p=0.693); the storage symptoms improved significantly more with TAM+SR (-1.7 vs. -0.8 with TAM, p=0.024). This benefit with regard to storage symptom in the TAM+SR group lasts at 12 months (-1.9 vs. -0.9, p=0.024). The changes of voiding subscore, LUTS-related QoL, Qmax, PVR, PSA, and prostate volume showed no significant differences between the TAM+SR and TAM groups. During the treatment period, 8 patients (16.9%) with TAM and 10 (20%) with TAM+SR had drug-related adverse reactions, which included ejaculatory disorders, postural hypotension, dizziness, headache, gastro-intestinal disorders, rhinitis, fatigue and asthenia. CONCLUSIONS The combination treatment of Serenoa repens and tamsulosin was shown to be more effective than tamsulosin monotherapy in reducing storage symptoms in BPH patients after 6 months and up to 12 months of treatment.

Abstract
PURPOSE The aim of this review is to discuss the negative effects on sexual function of medications for lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS-BPH). METHODS An international non-systematic literature review was performed. It included randomized trials of seven drugs of interest and the summaries of the characteristics of these products. This work did not aim comparison between the drugs. RESULTS Only maximal reported frequencies are presented in this abstract. With prolonged-release alfuzosin, they were 2.8% vs. 1.3% for erectile dysfunction, compared to placebo and 1% vs. 0% for ejaculatory dysfunction. With doxazosin, the incidence was 5.8% vs. 3.3% for erectile dysfunction, 3.6% vs. 1.9% for reduced libido and 0.4% vs. 1.4% for ejaculatory disorders. The incidence of ejaculatory disorders with tamsulosin, was 11% vs. <1% with the placebo and with silodosin, it was 28.1% vs. 1.1%. With finasteride, at 12 months, the highest frequency was 9% vs. 5% for erectile dysfunction, 4.4% vs. 1.5% for ejaculatory disorders and 6.4% vs. 3.4% for reduced libido. At 24 months, for dutatsteride, frequencies were 7.3% vs. 4.0% for erectile dysfunction, 2.2% vs. 0.8% for ejaculatory disorders and 4.2% vs. 2.1% for reduced libido. For tadalafil, a phosphodiesterase-5 inhibitor, and tolerodine, an anticholinergic drug, no negative effect on ejaculation or libido has been reported. For plant extracts, no sexual adverse effects (AEs) were reported among the most common AEs. CONCLUSION The medications for LUTS-BPH may alter erection, ejaculation or libido. A greater knowledge of the adverse effects of each of these drugs could guide physicians in the clinical management of men with BPH-LUTS.

Abstract
BACKGROUND Phytotherapy has been used to treat patients with lower urinary tract symptoms (LUTS). We evaluated the efficacy and tolerability of combination therapy between Serenoa Repens (SeR), Lycopene (Ly), and Selenium (Se) + tamsulosin versus single therapies. METHODS PROCOMB trial (ISRCTN78639965) was a randomized double-blinded, double-dummy multicenter study of 225 patients between 55 and 80 years old, PSA ≤ 4 ng/ml, IPSS ≥12, prostate volume ≤60 cc, Qmax ≤15 ml/sec, postvoid residual urine (PVR) <150 ml. Participants were randomized group A (SeR-Se-Ly), group B (tamsulosin 0.4 mg), group C (SeR-Se-Ly + tamsulosin 0.4 mg). The primary endpoints of the study were the reduction of IPSS, PVR, and increase of Qmax in group C versus monotherapy groups. RESULTS The decrease for combination therapy was significantly greater versus group A (P < 0.05) and group B (P < 0.01) for IPSS and versus group A (P < 0.01) for PVR from baseline to 6 months. A greater decrease in IPSS was observed for Group C versus group A (P < 0.01) and increase in Qmax versus group B (P < 0.01), from 6 months to 12 months. At one year, the changes of IPSS and Qmax were greater for Group C versus monotherapies (each comparison <0.05). The proportions of men with a decrease of at least three points (each comparison P < 0.05) and decrease of 25% for IPSS (each comparison P < 0.01) were greater for Group C. CONCLUSION SeR-Se-Ly + tamsulosin therapy is more effective than single therapies in improving IPSS and increasing Qmax in patients with LUTS.

Abstract
Benign prostate hyperplasia (BPH) is a common condition affecting older men, with an incidence that is age-dependent. Histological BPH, which typically develops after the age of 40 years, ranges in prevalence from >50% at 60 years to as high as 90% by 85 years of age. Typical symptoms include increased frequency of urination, nocturia, urgency, hesitancy, and weak urine stream. Conventional medicines used for the treatment of BPH include alpha blockers and 5-alpha reductase inhibitors. This articles review the mode of action, the efficacy, and the safety, including herb-drug interactions of the most common botanicals (Serenoa repens, Pygeum africanum, Urtica dioica, and Cucurbita pepo) and nutraceuticals (isoflavones, lycopene, selenium, and β-Sitosterol) in controlling the lower urinary tract symptoms associated to BPH.

Abstract
INTRODUCTION The German Research Activities on Natural Urologicals (GRANU) study was a randomized, partially blinded, placebo-controlled, parallel-group trial that investigated the efficacy of pumpkin seed in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH/LUTS). SUBJECTS AND METHODS A total of 1,431 men (50-80 years) with BPH/LUTS were randomly assigned to either pumpkin seed (5 g b.i.d.), capsules with pumpkin seed extract (500 mg b.i.d.) or matching placebo. The primary response criterion was a decrease in International Prostate Symptom Score (IPSS) of ≥5 points from baseline after 12 months. Secondary outcome measures included IPSS-related quality of life, IPSS single items and diary-recorded nocturia. RESULTS After 12 months, the response rate (intention-to-treat/last-observation-carried-forward approach) did not differ between pumpkin seed extract and placebo. In the case of pumpkin seed (responders: 58.5%), the difference compared with placebo (responders: 47.3%) was descriptively significant. The study products were well tolerated. Overall, in men with BPH, 12 months of treatment with pumpkin seed led to a clinically relevant reduction in IPSS compared with placebo. CONCLUSION In order to fully justify a recommendation for the use of pumpkin seed to treat moderate LUTS, these findings need to be substantiated in a confirmatory study or systematic review.

Abstract
Purpose Smooth muscle contraction and prostate growth are important targets for medical therapy of lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia. Honokiol and Magnolol are lignan constituents of Magnolia species, which are used in traditional Asian medicine. Here, we examined effects of honokiol and magnolol on contraction of human prostate tissue and on growth of stromal cells. Methods Prostate tissues were obtained from radical prostatectomy. Contraction of prostate strips was examined in organ bath studies. Effects in stromal cells were assessed in cultured immortalized human prostate stromal cells (WPMY-1). Ki-67 mRNA was assessed by reverse transcription-polymerase chain reaction, and proliferation by a fluorescence 5-ethynyl-2′-deoxyuridine assay. Results Honokiol (100μM) reduced noradrenaline-induced contractions, which was significant at 10 to 100μM noradrenaline. Honokiol reduced phenylephrine-induced contractions, which was significant at 3 to 100μM phenylephrine. Honokiol reduced electric field stimulation-induced contractions very slightly. In WPMY-1 cells, honokiol (24 hours) induced cell death. Magnolol (100μM) was without effects on contraction, and cellular viability. Conclusions Honokiol inhibits smooth muscle contraction in the human prostate, and induces cell death in cultured stromal cells. Because prostate smooth muscle tone and prostate growth may cause LUTS, it appears possible that honokiol improves voiding symptoms.

Abstract
Benign prostatic hyperplasia (BPH) is a highly prevalent and costly condition that affects older men worldwide. Many affected men develop lower urinary tract symptoms, which can have a negative impact on their quality of life. In the past, transurethral resection of the prostate (TURP) was the mainstay of treatment. However, several efficacious drug treatments have been developed, which have transformed BPH from an acute surgical entity to a chronic medical condition. Specifically, multiple clinical trials have shown that α adrenoceptor antagonists can significantly ameliorate lower urinary tract symptoms. Moreover, 5α reductase inhibitors, alone or combined with an α adrenoceptor antagonist, can reverse the natural course of BPH, reducing the risk of urinary retention and the need for surgical intervention. Newer medical regimens including the use of antimuscarinic agents or phosphodiesterase type 5 inhibitors, have shown promise in men with predominantly storage symptoms and concomitant erectile dysfunction, respectively. For men who do not adequately respond to conservative measures or pharmacotherapy, minimally invasive surgical techniques (such as transurethral needle ablation, microwave thermotherapy, and prostatic urethral lift) may be of benefit, although they lack the durability of TURP. A variety of laser procedures have also been introduced, whose improved hemostatic properties abrogate many of the complications associated with traditional surgery.
