Abstract
6-Nitrodopamine (6-ND) is released from human vas deferens and plays a modulatory role in the male ejaculation. Therapeutical use of α1-adrenoceptor antagonists is associated with ejaculatory abnormalities. To evaluate the effect of α1-adrenoceptor antagonists on the contractions induced by 6-ND, dopamine, noradrenaline, and adrenaline in the human epididymal vas deferens (HEVD). HEVD strips were suspended in glass chambers containing heated and oxygenated Krebs-Henseleit's solution. Cumulative concentration-response curves to catecholamines (10 nM-300 μM) were constructed in HEVD strips pre-incubated (30 min) with doxazosin (0.1-1 nM), tamsulosin (1-10 nM), prazosin (10-100 nM) and/or silodosin (0.1-10 nM). The effects of these α1-adrenoceptor antagonists were also evaluated in the electric-field stimulation (EFS, 2-32 Hz)-induced contractions. Doxazosin (0.1 nM) caused significant reductions in 6-ND-induced HEVD contractions without affecting the contractions induced by dopamine, noradrenaline, and adrenaline. Similar results were observed with tamsulosin (1 nM) and prazosin (10 nM). At these concentrations, these α1-adrenoceptor antagonists largely reduced the EFS-induced contractions. Silodosin (1 nM) caused concentration-dependent rightward shifts of the concentration-response curves to 6-ND but had no effect on the contractions induced by dopamine and adrenaline. Silodosin (0.1 nM) only inhibited the contractions induced by noradrenaline. Silodosin at 1 nM, but not at 0.1 nM, caused significant reductions in the EFS-induced contractions. The results reinforce the concept that 6-ND plays a major role in the human vas deferens contractility and indicate that the ejaculation disorders caused by doxazosin, tamsulosin, prazosin and silodosin cause in man, may be due to inhibition of the contractions induced by 6-ND rather than by the classical catecholamines dopamine, noradrenaline, and adrenaline.

Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH), as a clinical entity that affects many people, has always been in the forefront of interest among researchers, pharmaceutical companies, and physicians. Patients with BPH exhibit a diverse range of symptoms, while current treatment options can occasionally cause adverse events. All the aforementioned have led to an increased demand for more effective treatment options. AREAS COVERED This review summarizes the outcomes of new medications used in a pre-clinical and clinical setting for the management of male lower urinary tract symptoms (LUTS)/BPH and provides information about ongoing trials and future directions in the management of this condition. More specifically, sheds light upon drug categories, such as reductase‑adrenoceptor antagonists, drugs interfering with the nitric oxide (NO)/cyclic guanosine monophosphate (GMP) signaling pathway, onabotulinumtoxinA, vitamin D3 (calcitriol) analogues, selective cannabinoid (CB) receptor agonists, talaporfin sodium, inhibitor of transforming growth factor beta 1 (TGF-β1), drugs targeting the hormonal control of the prostate, phytotherapy, and many more. EXPERT OPINION Clinical trials are being conducted on a number of new medications that may emerge as effective therapeutic alternatives in the coming years.

Abstract
The management of benign prostatic obstruction (BPO) should involve a treatment algorithm that takes into account prostate size, and patient's symptoms and preference with the aim of helping with urinary symptoms and enhance quality of life. The diagnostic assessment for men with lower urinary tract symptoms (LUTS) should be comprehensive to help choose the best management strategy. Strategies from lifestyle modifications to medical treatment with alpha blockers and/or 5-alpha-reductase inhibitors to surgical procedures can all be used in the management algorithm. Surgical management ranges from transurethral resection of prostate (TURP) to minimally invasive surgical therapies (MIST) including laser therapies such as Holmium laser enucleation (HoLEP) and photoselective vaporisation (PVP), aquablation, Rezūm system, prostate artery embolisation (PAE), prostatic urethral lift (PUL), temporary implantable nitinol device (iTind) and Optilume BPH catheter system. BPO is a common urological condition that has a significant impact on quality of life and economic burden globally and is likely to become increasingly prevalent with an ageing population. Selecting the most appropriate treatment modality will depend on the individual patient preferences, availability of resources, cost, anatomical factors and the goals of treatment.

Abstract
Adrenoceptors importantly contribute to the physiological regulation of lower urinary tract (LUT) function and have become a target of several clinically successful treatments for major LUT diseases. In the bladder dome, β-adrenoceptor subtypes are found in multiple cell types and mediate relaxation of detrusor smooth muscle, perhaps partly indirectly by acting on afferent nerves and cells of the mucosa. β3-adrenoceptor agonists such as mirabegron and vibegron are used to treat overactive bladder syndrome. In the bladder trigone and urethra, α1-adrenoceptors cause contraction and thereby physiologically contribute to bladder outlet resistance. α1-adrenoceptors in the prostate also cause contraction and pathophysiologically elevate bladder outlet resistance leading to voiding dysfunction in benign prostatic hyperplasia. α1-adrenoceptor antagonist such as tamsulosin is widely used as a first-line option to treat LUT symptoms in men, but it remains unclear to which extent and how smooth muscle relaxation contributes to symptom relief.

Abstract
INTRODUCTION The drug classes of α1-adrenoceptor antagonists, 5α-reductase inhibitors, and phosphodiesterase type 5 inhibitors are guideline-recommended treatments of lower urinary tract symptoms suggestive of benign prostatic hyperplasia; muscarinic receptor antagonists and β3-adrenoceptor agonists are also recommended if storage symptoms are insufficiently addressed with one of the other three drug classes. AREAS COVERED We provide a narrative review (no formalized literature searches performed) of the tolerability of these drug classes with emphasis on the more recently introduced medications, on combination treatment, and on more lately emerging risks. EXPERT OPINION/COMMENTARY The tolerability profiles are distinct between drug classes but, with few exceptions, similar within a drug class. Within a drug, formulations with longer duration of action tend to have better tolerability. Efficacy gains using combination treatment at least partly come at a cost of lesser tolerability. Greater susceptibility to experience adverse events based on age, comorbidities, and comedications appears conceptually important but remains under-investigated in this therapeutic area.

Abstract
BACKGROUND Alpha-adrenoreceptor antagonists or alpha-blockers are used in the treatment of hypertension, in the therapy of benign prostatic hyperplasia and in medical expulsive treatment of ureteral stones. These agents may affect the sexual function, with differences between drugs within the same class, depending on their selectivity for receptor subtypes. The aim of this review was to analyze the effects of alpha-blockers on sexual function. MATERIALS AND METHODS We conducted a systematic review and meta-analysis by searching PubMed, EMBASE and other databases for randomized controlled trials (RCTs) reporting sexual adverse effects in patients treated with alpha-blockers. Odds ratios for sexual dysfunction were calculated using random effects Mantel-Haenszel statistics. RESULTS Out of 608 records retrieved, 75 eligible RCTs were included in the meta-analysis. Compared with placebo, alphablockers were associated with increased odds of ejaculatory disorders both in patients with lower urinary tract symptoms (LUTS) associated to benign prostatic hyperplasia (BPH) (OR: 7.53, 95% CI: 3.77-15.02, Z = 5.73, p < 0.00001, I2 = 55%) and in patients with ureteral stones (OR: 2.88, 95% CI: 1.50-5.44, Z = 3.19, p < 0.001, I2 = 31%). Uroselective alpha-blockers showed higher odds of ejaculatory disorders. Conversely, nonselective alpha-blockers were not associated with higher odds of ejaculatory dysfunction. Silodosin was associated with increased odds of ejaculatory dysfunction compared with tamsulosin (OR: 3.52, 95% CI: 2.18-5.68, 15 series, 1512 participants, Z = 5.15, p < 0.00001, I2 = 0%). Naftopidil and alfuzosin showed lower odds of ejaculatory dysfunction compared to uroselective alpha-blockers.No statistically significant differences in the odds of erectile dysfunction were observed when alpha-blockers were compared to placebo.

Abstract
We aimed to evaluate the effect of the abnormal ejaculation (AEj) on patients using silodosin in terms of drug cessation. We also analysed the possible factors that may affect the decisions of patients with AEj to proceed or change their medication. The patients (n = 118) treated with silodosin 8 mg daily were prospectively analysed. In order to evaluate the erectile function, ejaculatory function, depression and sexual satisfaction; IIEF, MSHQ-EjD, Beck's depression and Golombok-Rust questionnaires were given to patients respectively. Patients were re-evaluated at the 3rd month of their treatment. The rate of AEj was 52.5%. Nearly 42% of the patients with AEj desired to stop their medication whereas it was 7.1% at patients without AEj (p < .001). The pre-treatment International Prostate Symptom Score (IPSS) and the decrease in IPSS score were significantly lower in patients who demand to stop their treatment (p < .05). AEj was significantly higher in patients who wanted to stop their medication (p < .001). Even if they had an AEj, patients who were happy with the clinical efficacy of silodosin did not want to change their drug. In addition to this, pre-treatment ejaculatory status was an important indicator for patients to decide drug cessation due to AEj side effect of silodosin.

Immunolocalization of Adrenoceptors in the Reproductive Tract of Male Domestic Cats in Comparison to Rats. Animals (Basel) 2021; 11:ani11041049.

Abstract
Simple Summary In cats, semen is collected by pharmacological stimulation. The administration of a drug that stimulates α2-adrenoceptors causes the expulsion of spermatozoa into the urethra. However, as the results are not always satisfactory, this method needs to be improved. There are nine subtypes of adrenoceptors that are involved in the contraction of smooth muscle, including those in the reproductive tract, so adrenoceptors other than the α2-subtype are potential targets in any new, optimized protocol. The aim of this study was to analyze the immunolocalization of the adrenergic receptors in the reproductive tract of the male cat for the first time in this species. The expression of all adrenoceptor subtypes was noted in the peritubular smooth muscle in cats, indicating a potential clinical application for agonists of these receptors for the optimization of the pharmacological semen collection in felids. In a broader context, the development of a new procedure for semen collection in the male cat, using active substances from groups other than those currently used, will support the wider application of reproductive biotechnologies in felids. Abstract Adrenoceptors mediate the action of the sympathetic nervous system, including the contraction of the epididymis and vas deferens. The aim of this study was to immunolocalize the adrenergic receptors in the reproductive tract of the male cat, as this information is not yet available. The epididymis and vas deferens of domestic cats and rats (the biological controls) were analyzed by immunohistochemistry to determine the localization of the α1A-, α1B-, α1D-, α2A-, α2B-, α2C-, β1-, β2-, and β3-adrenoceptors. All the receptors were expressed in the peritubular smooth muscles of the cat, but the α1D-, α2C-, and β1-adrenoceptors were not detected in this tissue in the rat. For the α2A-adrenoceptor, the intensity of immunostaining differed significantly between the caput epididymis (weakest staining) and the vas deferens (strongest staining). The presence of all the types of the receptors was also detected in the cytoplasm of the epithelial cells in all the regions of the reproductive tract. The strong expression of the α2A-adrenoreceptor suggests it has a leading role in the contraction of the reproductive tract in the cat. The presence of other adrenergic receptors in the smooth muscle of the epididymis and vas deferens indicates a potential clinical application for α1-mimetics in the optimization of pharmacological semen collection in felids.

Abstract
Background The purpose of this study was to compare once daily (QD) usage of 4 and 8 mg of silodosin in patients divided as those with moderate and with severe lower urinary tract symptoms (LUTSs) according to International Prostate Symptom Score (IPSS) categories in terms of effectiveness and adverse events. Methods A total of 234 patients aged ≥ 40 years were evaluated prospectively. All participants were divided firstly into two groups according to their IPSS severity as moderate and severe. They were further allocated to receive 4 mg of silodosin and 8 mg of silodosin QD. Demographic features and laboratory tests were recorded. The patients were questioned with International Index of Erectile Function-5 and IPSS along with quality of life index. Uroflowmetric measurements were applied to the patients. All tests and measurements were repeated at the 3rd month, and changes from pretreatment to posttreatment were analyzed by SPSS 21.0 Program. The statistical significance level was set at p < 0.05. Results Both treatments provided benefit in patients with both moderate and severe LUTSs. While results did not differ among 4 mg and 8 mg of silodosin in patients with moderate LUTSs, 8 mg of silodosin was significantly better than 4mg in those with severe LUTSs in terms of improvement of the total IPSS, IPSS voiding subtotal score, and quality of life score (p = 0.015, 0.030, <0.001, respectively). Both treatments did not affect erectile functions. Adverse events were seen more frequently in patients receiving 8 mg of silodosin than those treated with 4 mg of silodosin (p = 0.024). Conclusion Our study revealed that 4 mg of silodosin QD was as effective as 8 mg of silodosin QD in patients with moderate LUTSs but not with severe LUTSs. It can be inferred from this study that prescription of 4 and 8 mg of silodosin may be chosen to treat the patients with moderate and severe LUTSs due to benign prostatic heperplasia, respectively.

Abstract
BACKGROUND Sexual dysfunction is a common side effect of medical therapy for benign prostatic hyperplasia (BPH), whereas prostatic urethral lift (PUL) offers safe and effective relief of lower urinary tract symptoms while preserving sexual function. OBJECTIVE To compare the long-term impact on sexual health of PUL or daily medical therapy of doxazosin or finasteride alone or in combination in BPH patients. DESIGN, SETTING, AND PARTICIPANTS This was a comparative analysis of sexual function outcomes from PUL studies (L.I.F.T. [n=107], Crossover [n=42], and MedLift [n=39]) and the Medical Therapy of Prostatic Symptoms (MTOPS) trial. The men included were sexually active with International Prostate Symptom Score ≥13, Qmax ≤12ml/s, and prostate volume 30-80 cm3. MTOPS subjects completed the Brief Male Sexual Function Inventory, while PUL subjects completed the International Index of Erectile Function and the Male Sexual Health Questionnaire for Ejaculatory Function. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Mean percentage changes from baseline in erectile, ejaculatory, and sexual satisfaction domains were compared at 12, 24, 36, and 48 mo. RESULTS AND LIMITATIONS PUL significantly improved erectile function through 24 mo, and ejaculatory function and sexual satisfaction across all time points. Medical therapy did not improve sexual function at any time point. Finasteride significantly decreased erectile function at 48 mo, and combined therapy significantly reduced ejaculatory function at 12 and 24 mo. Comparatively, PUL was superior to finasteride in preserving erectile function at 24 and 48 mo, and superior to doxazosin and combined therapy at 12 mo. PUL outperformed all three medical therapies at all time points in improving ejaculatory function and sexual satisfaction. Limitations include the use of distinct patient-reported questionnaires and narrowed data on comorbidities that influence male sexual function. CONCLUSIONS Indirect comparison reveals that PUL is superior to BPH medical therapy in preserving erectile and ejaculatory function and sexual satisfaction. PATIENT SUMMARY In our non-head-to-head study, only patients undergoing PUL for an enlarged prostate experienced improvements in sexual health. Conversely, patients on medical therapy experienced worsening of erectile and ejaculatory function.

Abstract
The diagnosis and treatment of lower urinary tract symptoms (LUTS) due to benign prostatic enlargement plays an important role in daily urological practice. Therefore, a targeted and resource-saving approach is essential. A rational base-line work-up of our patients provides the necessary information for obtaining the diagnosis and only needs to be expanded in individual cases. In addition to drug therapy, the modification of lifestyle and the possibility of watchful waiting must not be underestimated. Simple measures such as a timed fluid intake, double micturition in the case of residual urine development, but also bladder reconditioning can significantly improve the quality of life of our patients. Regarding surgical treatment, laser procedures have found their way into many departments and have established themselves in daily routine as a reference procedure in addition to transurethral resection of the prostate (TUR-P) and simple open prostatectomy. New, minimally invasive procedures-such as prostatic artery embolization (PAE), the Rezum™- (NxThera Inc., Maple-Grove, MN, USA) or the Aquabeam® (Procept, Redwood City, CA, USA) procedure, but also nonablative procedures such as iTind© (TIND, Medi-Tate, Or Akiva, Israel) or Urolift® (Neotract Inc., Pleasanton, CA, USA)-offer new treatment options to those affected, with the potential to maintain patient's sexual function. As a result, individual risk assessment and advice on the advantages and disadvantages of all available treatment options-even more than today-will be an important part of LUTS treatment. An individual approach, similar to that used in the treatment of oncological disease, will become standard also in the treatment of benign prostatic syndrome.

Abstract
RESEARCH QUESTION Is there an association between the use of sympathomimetics for asthmatic disease and semen quality in humans? DESIGN Between 2007 and 2012 a prospective cohort study was conducted among couples visiting the preconception counselling clinic at a tertiary hospital in the Netherlands. The study included 882 men of subfertile couples and information on medication use was obtained from self-administered questionnaires. Moreover, data on semen parameters were retrieved from medical records. RESULTS The study population of men revealed a mean (± SD) age of 34 ± 4 years with a mean body mass index (BMI) of 26.1 ± 2.3 kg/m2, and sympathomimetic use was reported by 3.6%. The use of sympathomimetics was positively associated with a 10% higher sperm motility (beta 10.265; 95% confidence interval [CI] 3.258-17.272) after adjustment for smoking, alcohol use, age, geographic background, BMI, folic acid supplement use, the four astronomical seasons and asthma/bronchitis. Subgroup analysis between men with total motile sperm count (TMSC) < or ≥10 million showed that this association remained (P ≤ 0.001) after adjustment for these confounders. After adjustment for confounders the sperm concentration was also positively associated with the use of sympathomimetics, but only in men with TMSC ≥10 million (beta 0.300; 95% CI 0.032-0.568). CONCLUSIONS These preliminary data show the potential benefits of the use of sympathomimetics to improve sperm motility in men of subfertile couples, which needs further investigation.

Abstract
Introduction: Muscarinic receptor antagonists, 5α-reductase inhibitors and α1-adrenoceptor antagonists are frequently used drug classes for the treatment of lower urinary tract symptoms including those of overactive bladder syndrome and benign prostatic enlargement/benign prostatic obstruction. Areas covered: The authors review the evidence for adverse effects of these drug classes on cognitive function, mood and other functions of the central nervous system and discuss such effects against the evidence for mechanistic plausibility. Expert opinion: Muscarinic antagonists carry a risk for impaired cognition and other brain functions that differs quantitatively between compounds, being highest with oral formulations of oxybutynin. 5□-Reductase inhibitors can cause depressive symptoms even at low doses and starting several months after discontinuation of treatment. The evidence for α1-adrenoceptor antagonists and specifically tamsulosin to cause dementia is controversial and lacks mechanistic plausibility. We recommend that physicians treating patients with lower urinary tract symptoms carefully monitor mental status prior to prescribing and periodically thereafter.

Abstract
Spontaneous myogenic contractions have been shown to be significantly upregulated in prostate tissue collected from men with Benign Prostatic Hyperplasia (BPH), an extremely common disorder of the ageing male. Although originally thought likely to be involved in 'housekeeping' functions, mixing prostatic secretions to prevent stagnation, these spontaneous myogenic contractions provide a novel opportunity to understand and treat BPH. This treatment potential differs from previous models, which focused exclusively on attenuating nerve-mediated neurogenic contractions. Previous studies in the rodent prostate have provided an insight into the mechanisms underlying the regulation of myogenic contractions. 'Prostatic Interstitial Cells' (PICs) within the prostate appear to generate pacemaker potentials, which arise from the summation of number of spontaneous transient depolarisations triggered by the spontaneous release of Ca2+ from internal stores and the opening of Ca2+-activated Cl- channels. Pacemaker potentials then conduct into neighbouring smooth muscle cells to generate spontaneous slow waves. These slow waves trigger the firing of 'spike-like' action potentials, Ca2+ entry and contraction, which are not attenuated by blockers of neurotransmission. However, these spontaneous prostatic contractions can be modulated by the autonomic nervous system. Here, we discuss the mechanisms underlying rodent and human prostate myogenic contractions and the actions of existing and novel pharmacotherapies for the treatment of BPH. Understanding the generation of human prostatic smooth muscle tone will confirm the mechanism of action of existing drugs, inform the identification and effectiveness of new pharmacotherapies, as well as predict patient outcomes.

Abstract
PURPOSE Recently, several randomized controlled trials (RCTs) explored the effects of α-blockers with or without phosphodiesterase type 5 inhibitors (PDE5-Is) for lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH). However, the results were inconsistent. We performed this meta-analysis to evaluate the role of combination therapy (α-blockers and PDE5-Is) in patients with LUTS/BPH. MATERIALS AND METHODS Databases including PubMed, Cochrane library, Web of Science, and Embase were searched for qualified RCTs. Pooled mean differences (MDs) and odds ratios (ORs) were calculated to measure the effects and adverse events in combination therapy. Moreover, subgroup analyses of ethnicity, dosage of PDE5-Is, treatment duration, and severity of LUTS/BPH were performed. In addition, trial sequential analyses (TSAs) were used to assess whether the evidence for the results was sufficient. RESULTS Overall, this study identified 11 eligible RCTs, including 855 LUTS/BPH patients. Patients receiving combination therapy had better improvement in international prostate symptom score (IPSS: MD: 1.66, 95% CI - 3.03 to - 0.29), maximum urinary flow rate (Qmax: MD: 0.94, 95% CI 0.24-1.64), and international index of erectile function (IIEF: MD: 4.73, 95% CI 2.95-6.51), comparing those without PDE5-Is. Besides, subgroup analyses indicated that the effects of combination treatment were associated with ethnicity, treatment duration, and severity of LUTS/BPH. By TSA, the findings in the current study were based on sufficient evidence. CONCLUSIONS Our results indicated that combination therapy can significantly improve IPSS, Qmax, and IIEF in patients with LUTS/BPH. Combination therapy might be more suitable for these patients.

Abstract
Medical therapy for clinical benign prostatic hyperplasia (BPH) has advanced significantly in the last 2 decades. Many new α1 antagonists and 5α reductase inhibitors (5ARi) are now commercially available. The practicing urologist must decide on the most appropriate medication for his patients, taking into consideration various factors like efficacy, dosing regime, adverse effects, cost, patient's socioeconomic background, expectations, drug availability and his own clinical experience. The use of combination therapy added further to the complexity in clinical judgment when prescribing. We highlight some of the key points in prescribing α1 antagonists, 5ARi and their combination, based on our viewpoints and experience as urologists in an Asian clinical setting.

Abstract
Benign prostatic hyperplasia (BPH) is one of the most common genitourinary complications in men over 50 years of age and typically presents with lower urinary tract symptoms (LUTS). Classes of medications include α1-adrenoceptor blockers, 5α-reductase inhibitors, and phosphodiesterase 5 inhibitors. Today, α1-adrenoceptor blockers and 5α-reductase inhibitors are often combined to give a synergistic effect. A review of the current literature identified several adverse sexual side effects, including erectile dysfunction (ED), decreased libido, orgasmic disorders, and ejaculatory disorders. We believe it is important to know the extent of these side effects, as the clinician and patient will need to decide the cost of improved voiding symptoms. The chief adverse effect is ejaculatory disorders, including the absence of ejaculation. Clinical consideration for BPH should include the elements of male sexual function, patients’ age, and the characteristics and comprehensive effects of each group of drugs. Methodological bias in clinical studies, such as the subjective evaluation of the sexual side effect, makes it difficult to determine the ideal drug for treatment.

Abstract
As men age, there is an increased incidence of lower urinary tract symptoms (LUTS), often from benign prostatic hyperplasia (BPH) which can adversely affect sexual function. There are many different treatments for these symptoms; however, many of the treatments also affect sexual quality of life, specifically in the realm of ejaculation. Our paper will review the medications, surgical procedures, minimally invasive procedures, and even investigational procedures used to treat LUTS/BPH and the effect they have on ejaculation. The aim of this paper is to help practitioners counsel patients more effectively on treatment options when ejaculation is a concern.

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
AIM We investigated the effects of silodosin (selective α1A -adrenoceptor antagonist) on erectile dysfunction (ED) in a rat model of bladder outlet obstruction. METHODS Adult male Sprague-Dawley rats (n = 32) were divided into four groups: (i) sham-operated control; (ii) silodosin-treated (sham) control (0.1 mg/kg/day); (iii) partial bladder outlet obstruction (PBOO); and (iv) silodosin-treated with PBOO. PBOO was induced by ligation of the urethra for 6 weeks. In vivo, erectile responses were monitored by evaluating ratios of intracavernosal pressure (ICP)/mean arterial pressure (MAP). Organ-bath studies were performed on corpus cavernosum (CC) strips. Penises were assessed at baseline for protein expression of neuronal nitric oxide synthase (nNOS) and Rho-associated protein kinase (ROCK2) by Western blot. Immunohistochemistry and Masson trichrome staining were performed for analysis of nNOS protein levels and tissue alterations. RESULTS The ratio of ICP/MAP was significantly decreased in obstructed rats (0.26 ± 0.043, P < 0.01) compared to sham-control rats (0.64 ± 0.10), which was restored by the treatment (0.59 ± 0.14, P < 0.01) compared with obstructed rats. Relaxation responses were significantly reduced in strips from the obstructed group. Silodosin restored nitrergic relaxant responses. nNOS expression in the obstructed group decreased, which was improved by treatment. The decreased smooth muscle/collagen ratio in the bladder obstructed group was reversed by the treatment. CONCLUSIONS Silodosin improves erectile function in obstructed rats. Further clinical trials are needed to explore fully the potential benefits of silodosin in patients with benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) in association with ED.

Abstract
Despite their multifactorial etiology, male lower urinary tract symptoms (LUTS) have been traditionally associated with benign prostatic enlargement (BPE) because of benign prostatic hyperplasia (BPH). Several pharmaceutical therapies have been used to manage LUTS, with α1-adrenergic receptor antagonists (α1-blockers) and inhibitors of 5α-reductase (5α-RIs) representing the most commonly prescribed agents currently in use for LUTS treatment. Due to their different modes of action, combined use of α1-blockers and 5α-RIs has been proven to offer more optimal control of symptoms and better associated quality of life, even though higher rates of adverse events have been shown. Following previous studies on the separate administration of dutasteride and tamsulosin, a fixed-dose combination capsule of tamsulosin 0.4 mg and dutasteride 0.5 mg has been approved and released for clinical use in men with BPH. The present review aims to discuss the rationale behind the combined use of tamsulosin and dutasteride for treating male LUTS, and to present the available data on the role of combination therapy in the management of BPH-related symptoms in terms of efficacy and safety. Special attention is given to the impact of combination treatment on the prevention of clinical progression of BPH. Cost-effectiveness of fixed-dose combination and patients' adherence to treatment are also discussed.

Abstract
In 2014, the Korean Urological Association organized the Benign Prostatic Hyperplasia Guideline Developing Committee composed of experts in the field of benign prostatic hyperplasia (BPH) with the participation of the Korean Academy of Family Medicine and the Korean Continence Society to develop a Korean clinical practice guideline for BPH. The purpose of this clinical practice guideline is to provide current and comprehensive recommendations for the evaluation and treatment of BPH. The committee developed the guideline mainly by adapting existing guidelines and partially by using the de novo method. A comprehensive literature review was carried out primarily from 2009 to 2013 by using medical search engines including data from Korea. Based on the published evidence, recommendations were synthesized, and the level of evidence of the recommendations was determined by using methods adapted from the 2011 Oxford Centre for Evidence-Based Medicine. Meta-analysis was done for one key question and four recommendations. A draft guideline was reviewed by expert peer reviewers and discussed at an expert consensus meeting until final agreement was achieved. This evidence-based guideline for BPH provides recommendations to primary practitioners and urologists for the diagnosis and treatment of BPH in men older than 40 years.

A single oral dose of Silodosin and Diclofenac sodium is effective in reducing pain after ureteric stent removal: a prospective, randomized, double blind placebo-controlled study. SPRINGERPLUS 2016; 5:23.

Abstract
A prospective double-blinded placebo controlled randomized study was conducted in our institute to compare the efficacy of oral Silodosin, an alpha 1 selective antagonist and Diclofenac in relieving pain after stent removal. All patients with unilateral stent placement following renal and ureteric stone endoscopic surgery were randomized into four groups: group A (Placebo), group B (Diclofenac), group C (Silodosin) and group D (combination of Diclofenac and Silodosin). Visual analogue score (VAS score) and other relevant parameters were assessed during OPD visit. Patients were handed over randomized drug envelope and asked to take the medications one hour before the stent removal. Patients were contacted 24 h after stent removal and relevant parameters were recorded. The mean VAS scores were significantly decreased in Diclofenac (2.9), Silodosin (3.08) and combination group (2.85) when compared to placebo (4.20) (p < 0.001). However there was no statistically significant difference in VAS scores between the treatment groups, i.e., group B, C and D (p > 0.5). Analgesics requirement and severe pain rates were not significantly reduced (p = 0.07, 0.35) in the three treatment groups when compared to placebo. Thus Silodosin and Diclofenac, both are effective in preventing pain after stent removal.

Abstract
OBJECTIVE To explore and quantify men's preferences and willingness to pay (WTP) for attributes of medications for lower urinary tract symptoms associated with benign prostatic hyperplasia using a discrete choice experiment. SUBJECTS AND METHODS Men in the UK aged ≥45 years with moderate-to-severe lower urinary tract symptoms/benign prostatic hyperplasia (based on self-reported International Prostate Symptom Score ≥8) were recruited. An online discrete choice experiment survey was administered. Eligible men were asked to consider different medication scenarios and select their preferred medication according to seven attributes: daytime and nighttime (nocturia) urinary frequency, urinary urgency, sexual and nonsexual side effects, number of tablets/day, and cost/month. A mixed-logit model was used to estimate preferences and WTP for medication attributes. RESULTS In all, 247 men completed the survey. Men were willing to trade-off symptom improvements and treatment side effects. Men preferred medications that reduced urinary urgency and reduced day- and nighttime urinary frequency. Men preferred medications without side effects (base-case level), but did not care about the number of tablets per day. WTP for symptomatic improvement was £25.33/month for reduced urgency (urge incontinence to mild urgency), and £6.65/month and £1.39/month for each unit reduction in night- and daytime urination frequency, respectively. The sexual and nonsexual side effects reduced WTP by up to £30.07/month. There was significant heterogeneity in preferences for most attributes, except for reduced urinary urgency from urge incontinence to mild urgency and no fluid during ejaculation (dry orgasm). CONCLUSION To compensate for side effects, a medicine for lower urinary tract symptoms/benign prostatic hyperplasia must provide a combination of benefits, such as reduced urgency of urination plus reduced nighttime and/or reduced daytime urination.

Abstract
Treatment of male lower urinary tract symptoms (LUTS) has traditionally focused on the management of benign prostatic obstruction, but the contribution of bladder dysfunction has been recently recognized. Therefore, it is well understood that LUTS have multifactorial etiology and often occur in clusters and not in isolation. Voiding LUTS are highly prevalent in men, but storage LUTS have been proved to be more bothersome. α1-Blockers are the most widely used pharmacologic agents for the treatment of symptoms relating to benign prostatic enlargement due to benign prostatic hyperplasia (BPH), while antimuscarinics are the drug class of choice for overactive bladder symptoms. A combination of the two drug classes would be a reasonable approach to treat men with both storage and voiding symptoms, and several short-term studies have proved the efficacy and safety of different combinations with an α1-blocker and an antimuscarinic. Following previous studies on the separate administration of solifenacin and tamsulosin, a fixed-dose combination tablet of tamsulosin oral controlled absorption system (OCAS) 0.4 mg and solifenacin succinate 6 mg has been recently introduced, and the current review evaluates the available data on the use of this fixed-dose combination in the treatment of LUTS in men with BPH.

Abstract
CONTEXT Treatment for lower urinary tract symptoms resulting from benign prostatic hyperplasia (BPH) is varied, and significant side effects, particularly concerning sexual function, affect uptake. The prostatic urethral lift (PUL) procedure is a recent addition to the armamentarium for BPH treatment, with independent reports suggesting improvement of symptoms, sexual function, and urinary flow. OBJECTIVE We undertook a systematic review and meta-analysis of reported symptomatic, functional, and sexual outcomes following the PUL procedure. EVIDENCE ACQUISITION We performed a critical review of Medline, Embase, ScienceDirect, Cochrane Library, and Web of Science databases in May 2014 according to the Preferred Reporting Items for Systematic Review and Meta-Analysis statement. Quality assessment was performed using a modification of the Methodological Index for Non-Randomized Studies tool. All retrospective, prospective, and controlled trials were included for analysis. Symptom scores, sexual health scores, and functional outcomes were pooled and meta-analysed using quality and random-effects models. EVIDENCE SYNTHESIS Ten articles comprising six independent patient cohorts were included for analysis. Pooled estimates from between 452 and 680 patients suggested overall improvement following PUL, including symptoms (large gain; standardised mean gain range of 1.3-1.6, International Prostate Symptom Score difference of -7.2 to -8.7 points), maximum flow rate (3.8-4.0 ml/s), and quality of life (2.2-2.4 points). Sexual function was preserved with a small improvement estimated at 12 mo (standardised mean gain range of 0.3-0.4). Pooled estimates were mostly heterogeneous across study groups. CONCLUSIONS PUL is a well-tolerated, minimally invasive therapy for BPH that provides favourable symptom, sexual health, and functional outcomes during follow-up to 12 mo. Longer follow-up and larger randomised studies are required to further confirm these preliminary results. PATIENT SUMMARY We reviewed the early results of an innovative procedure directed towards the management of prostate enlargement. The results revealed a well-tolerated procedure that produces improvement in urinary symptoms and function while preserving sexual function.

Abstract
PURPOSE Previous studies have revealed that tamsulosin is effective in improving lower urinary tract symptoms (LUTS) and erectile functioning but has some inhibitory effects on ejaculation, including decreased ejaculatory volume. However, these inhibitory effects on ejaculation can be beneficial to patients with premature ejaculation (PE). Therefore, this study was conducted to understand the effect of tamsulosin on PE in men with benign prostatic hyperplasia. MATERIALS AND METHODS Twenty-nine patients who visited with LUTS were categorized into 2 groups of LUTS-only patients (n=12) and LUTS combined with PE (LUTS+PE) patients (n=17), and 0.4 mg of tamsulosin was administered to the patients of both groups for 12 weeks. Comparative analyses of before and after the treatment were conducted for calculating the International Prostate Symptom Score (IPSS), International Index of Erectile Function-5 (IIEF-5), intravaginal ejaculatory latency time (IELT), premature ejaculation diagnostic tool (PEDT), and premature ejaculation profile (PEP). The patients with an IPSS score of 8 or higher were determined as LUTS patients, and the patients with IELT of less than 2 minutess and a PEDT score of 9 or higher were determined as PE patients. RESULTS After treatment, the IPSS score significantly decreased in both groups. There was no statistically significant change in the PEDT for the LUTS group, but there was a significant decrease in PEDT (p=0.012; from 12.1±3.31 to 8.4±4.49) in the LUTS+PE group. CONCLUSIONS Tamsulosin not only has a treatment effect for LUTS but also improves the PE of LUTS+PE patients. Therefore, further studies are needed to confirm the effects of tamsulosin on PE.

Abstract
INTRODUCTION Erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) are both highly prevalent in aging men. Alpha-blockers and PDE-5 inhibitors are widely used for the treatment of LUTS/benign prostatic hyperplasia (BPH) and ED. AIM The purpose of this meta-analysis was to evaluate the efficacy of phosphodiesterase type 5 (PDE5) inhibitors alone or in combination with alpha-blockers for the treatment of ED and LUTS. METHODS The databases MEDLINE, EMBASE, PubMed, the Cochrane Controlled Trial Register of Controlled Trials, and the Chinese Biological Medical Database were searched to identify randomized controlled trials that referred to the use of a combination of PDE5 inhibitors and alpha-blockers for the treatment of ED and LUTS associated with BPH. A systematic review and meta-analysis was conducted. MAIN OUTCOME MEASURES International Prostate Symptom Score (IPSS), the maximum flow rate (Qmax), and International Index of Erectile Function-Erectile Function (IIEF-EF) domain score were used in this meta-analysis. RESULTS Seven publications involving 515 patients were included in the meta-analysis. In the analysis, we found significantly improved IIEF, IPSS, and Qmax values in the combination use group compared with the use of PDE5 inhibitors alone (P = 0.04, 0.004, 0.007, respectively). CONCLUSIONS The combined use of PDE5 inhibitors and alpha-blockers results in additive favorable effects in men with ED and LUTS suggestive of BPH compared with PDE5 inhibitor monotherapy. The alpha-blockers may enhance the efficacy of the PDE5 inhibitors, which is beneficial for the treatment of ED and LUTS.

Abstract
Several antihypertensive drugs, such as diuretics and β-blockers, can negatively affect sexual function, leading to diminished quality of life and often to noncompliance with the therapy. Other drug classes, however, such as angiotensin II receptor blockers (ARBs) are able to improve patients’ sexual function. Sufficient knowledge about the effects of these widely used antihypertensive drugs will make it possible for cardiologists and general practitioners to spare and even improve patients’ sexual health by switching to different classes of cardiac medication. Nevertheless, previous data (part I) indicate that most cardiologists lack knowledge about the effects cardiovascular agents can have on sexual function and will thus not be able to provide the necessary holistic patient care with regard to prescribing these drugs. To be able to improve healthcare on this point, we aimed to provide a practical overview, for use by cardiologists as well as other healthcare professionals, dealing with sexual dysfunction in their clinical practices. Therefore, a systematic review of the literature was performed. The eight most widely used classes of antihypertensive drugs have been categorised in a clear table, marking whether they have a positive, negative or no effect on sexual function.

Abstract
In recent years, research on penile erection has increasingly been centered on the molecular mechanisms involved. Major progress has been made in the field and at present a whole number of neurotransmitters, chemical effectors, growth factors, second-messenger molecules, ions, intercellular proteins, and hormones have been characterized as components of the complex process of erection. This knowledge has led to the discovery of several new therapeutic targets and multiple medical approaches for the treatment of erectile dysfunction (ED). This review focuses on the progress made in this field within the last few years.

Abstract
Lower urinary tract symptoms (LUTS) may be a sign of aging rather than a consequence of benign prostatic enlargement (BPE) or benign prostatic obstruction (BPO). Medical or invasive treatments should address the bothersome symptoms and the quality of life of patients. Alpha blockers and 5-alpha reductase inhibitors are most frequently used in benign prostatic hyperplasia (BPH) medical treatments, whereas Transurethral Resection of the Prostate (TURP) remains the "gold standard" for surgical treatments. Several minimal invasive treatments are emerging with promising outcomes.

Abstract
OBJECTIVE To present a summary of the 2013 version of the European Association of Urology guidelines on the treatment and follow-up of male lower urinary tract symptoms (LUTS). EVIDENCE ACQUISITION We conducted a literature search in computer databases for relevant articles published between 1966 and 31 October 2012. The Oxford classification system (2001) was used to determine the level of evidence for each article and to assign the grade of recommendation for each treatment modality. EVIDENCE SYNTHESIS Men with mild symptoms are suitable for watchful waiting. All men with bothersome LUTS should be offered lifestyle advice prior to or concurrent with any treatment. Men with bothersome moderate-to-severe LUTS quickly benefit from α1-blockers. Men with enlarged prostates, especially those >40ml, profit from 5α-reductase inhibitors (5-ARIs) that slowly reduce LUTS and the probability of urinary retention or the need for surgery. Antimuscarinics might be considered for patients who have predominant bladder storage symptoms. The phosphodiesterase type 5 inhibitor tadalafil can quickly reduce LUTS to a similar extent as α1-blockers, and it also improves erectile dysfunction. Desmopressin can be used in men with nocturia due to nocturnal polyuria. Treatment with an α1-blocker and 5-ARI (in men with enlarged prostates) or antimuscarinics (with persistent storage symptoms) combines the positive effects of either drug class to achieve greater efficacy. Prostate surgery is indicated in men with absolute indications or drug treatment-resistant LUTS due to benign prostatic obstruction. Transurethral resection of the prostate (TURP) is the current standard operation for men with prostates 30-80ml, whereas open surgery or transurethral holmium laser enucleation is appropriate for men with prostates >80ml. Alternatives for monopolar TURP include bipolar TURP and transurethral incision of the prostate (for glands <30ml) and laser treatments. Transurethral microwave therapy and transurethral needle ablation are effective minimally invasive treatments with higher retreatment rates compared with TURP. Prostate stents are an alternative to catheterisation for men unfit for surgery. Ethanol or botulinum toxin injections into the prostate are still experimental. CONCLUSIONS These symptom-oriented guidelines provide practical guidance for the management of men experiencing LUTS. The full version is available online (www.uroweb.org/gls/pdf/12_Male_LUTS.pdf).

Abstract
PURPOSE To investigate the relationship of improvement in erectile function (EF) with improvement in lower urinary tract symptoms (LUTS) and to assess the contribution of tamsulosin dose to the improvement of EF apart from the indirect influence of LUTS improvement in men with LUTS and erectile dysfunction (ED). MATERIALS AND METHODS Fifty patients received tamsulosin 0.2 mg/d for the first 4 weeks and were subsequently divided into two groups by patient-reported outcomes. Nonescalators were maintained starting dose and escalators increased to 0.4 mg for the remaining 8 weeks. International Prostatic Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5), and underwent uroflowmetry were evaluated at baseline, and weeks 4 and 12. RESULTS LUTS parameters were significantly improved in both groups but insignificant between the 2 groups. The degree of the improvement in the total IPSS and in the voiding, storage, and quality of life (QoL) subscores were significantly correlated with the degree of the improvement in EF; this was especially prominent in patients successfully treated LUTS. The escalators experienced a significantly greater increase in IIEF-5 scores than did the nonescalators (3.3 vs. 1.5). CONCLUSIONS Dose escalation provided similar LUTS improvement in patients with refractory to starting dose. The improvements of LUTS were correlated with the improvement of EF. The increase in the IIEF-5 score was significantly higher in escalators. These findings imply that tamsulosin may contribute to the improvement in EF through the improvement of LUTS and QoL and direct relaxation of the corpus cavernosum in a dose-dependent fashion.
