Clomiphene Citrate in the Management of Infertility in Oligospermic Obese Men with Hypogonadism: Retrospective Pilot Study.

Background and Objectives: Obesity is a significant risk factor for hypogonadism and infertility that is further associated with reduced semen quality. The aim of this study is to evaluate the effect of clomiphene citrate (CC), prescribed for treating infertility, on serum testosterone and semen parameters, particularly in oligospermic obese hypogonadal men. Materials and Methods: A retrospective analysis of data related to men (n = 53) who underwent CC treatment for infertility and hypogonadism (testosterone < 300 ng/dL) was performed. Patients with obesity (BMI ≥ 30 kg/m2) and sperm concentration ≤ 15 × 106/mL were included for analysis. Results: The overall results showed that, in oligospermic obese men (n = 31), treatment with CC significantly improved baseline sperm concentration (4.5 ± 6.8 × 106/mL vs. 11.4 ± 15.5 × 106/mL, p < 0.05) and motility (31.5% ± 21.5% vs. 42.6% ± 14.7%, p < 0.05). Furthermore, subsequent examination of oligospermic hypogonadal obese men treated with CC (n = 13) revealed substantial improvements in baseline serum testosterone levels (193.8 ± 59.3 ng/dL vs. 332.7 ± 114.8 ng/dL, p < 0.05) along with an increase in sperm concentration, total motility, and normal morphology. Conclusions: The results of this retrospective study suggest that CC treatment not only improves chances of fertility outcomes by substantially improving semen parameters but also increases total serum testosterone levels in oligospermic obese men without any supplemental and expensive testosterone replacement therapy.

Thyroid disorders and male sexual dysfunction.

Though early research suggested that thyroid hormones were not involved with the testes, male spermatogenesis, or erectile function, investigations on this topic over the past few decades have increased and shed new light. A literature review of studies conducted between 1963 and 2022 regarding male sexual dysfunction (SD) and thyroid disorders was performed to define the diagnostic consideration, pathophysiology, and management of SD secondary to thyroid dysregulation. This article provides evidence and interpretation of prior clinical and preclinical studies and contextualizes these studies for clinical practice. Clinical manifestations of SDs included erectile and ejaculatory dysfunction, impaired spermatogenesis, and disruption of the hypothalamic-pituitary-gonadal axis. Our aim of this communication was to perform a literature review detailing the impact of thyroid disorders on male SD. We hope to provide a framework for practicing urologists, endocrinologists, or general practitioners when evaluating patients with concurrent thyroid and male SD. It is important to recognize that thyroid disorders can be an important part of the pathophysiology of male SD in patients. Future research studies are needed to further elucidate the mechanisms involved.

Molecular mechanisms of penile traction for penile rehabilitation in a bilateral cavernous nerve crush injury rat model.

Background: Prostate cancer is the most common solid-organ malignancy in adult men. Early detection and treatment of prostate cancer with radical prostatectomy (RP) has improved cancer-specific survival but is associated with penile shortening and erectile dysfunction. Penile traction therapy (PTT) has been demonstrated to increase stretched penile length (SPL) prior to penile prosthesis placement and may improve erectile function (EF) in patients with Peyronie's disease. We aimed to evaluate the efficacy of PTT in preserving penile length and EF after bilateral cavernous nerve crush injury (BCNI) in a rat model. Methods: Twenty-four male Sprague-Dawley rats aged 11-13 weeks were randomly assigned to three groups (n=8, each): sham operation with no PTT (Sham), BCNI without PTT (Crush), and BCNI with PTT (Traction). PTT was started on postoperative day 3. A traction force of 1 Newton was applied to the penis for 30 minutes each day for 28 days. After 28 days of traction, the cavernous nerve was stimulated while recording the intracavernosal pressure (ICP) and the mean arterial pressure (MAP) simultaneously. Cavernosal tissue was excised, and western blot analysis for endothelial nitric oxide synthase (eNOS) was performed. Significance was determined by using ANOVA with Tukey-Kruger post-hoc testing. Results: At 4 weeks after nerve injury, the Traction group had significantly greater SPL compared to the Sham and Crush groups (30 vs. 28 and 27 mm, respectively). The Sham group had significantly greater EF (ΔICP/MAP) compared to the Crush group at 2.5, 5, and 7.5 V. The EF of the Traction group was between that of the Sham and Crush groups and was not significantly different from the Sham group at any voltages. Further downstream analysis revealed that the Traction group had significantly greater eNOS expression in cavernosal tissue compared to the Crush group, which was confirmed on western blot analysis and immunohistochemistry (IHC) staining. Conclusions: Findings from this animal study suggest that PTT has the potential to mitigate penile retraction after RP. While more studies are needed to determine the effect of PTT on preservation of EF, the increased eNOS expression observed in the Traction group offers a potential protective mechanism of action.

Phosphodiesterase 5 inhibitors: preclinical and early-phase breakthroughs for impotence treatments.

INTRODUCTION: Erectile dysfunction (ED) is a condition that affects millions of men worldwide and is characterized by the inability to achieve or maintain an erection for satisfactory sexual performance. There are numerous treatment options for ED, including medications, mechanical assist devices, and surgical management; however, first-line treatment is usually a phosphodiesterase 5 (PDE5) inhibitor. There is a growing interest in developing novel, efficacious PDE5 inhibitors that provide better quality, safety, and tolerability profiles with less adverse effects. Our review of udenafil, mirodenafil, youkenafil, lodenafil, and SLx-2101 analyzes the safety, efficacy, and pharmacokinetic properties of these new ED drugs. AREAS COVERED: Clinical trials demonstrated improved scores in questionnaires, such as the International Index of Erectile Function and Sexual Encounter Profile, for udenafil, mirodenafil, and lodenafil, while youkenafil and SLx-2101 revealed enhanced safety and tolerability in early pharmacokinetic studies. EXPERT OPINION: It is our opinion that more robust clinical trials are required before these medications can be made available in the United States. Additionally, the field of urology may benefit from pursuing other avenues of pharmacotherapy, such as injections, tablets with a different mechanism of action, or stem cell therapy, to restore the integrity of the endothelium within the penis.

Long-term assessment of the safety and effectivity of the mini-jupette sling: 5-year follow-up of the original series.

Background: In 2017, a prospective multicenter, multinational, investigational pilot study was conducted examining outcomes using a novel surgical technique, the Mini-Jupette sling, for the management of erectile dysfunction (ED) patients with climacturia and/or minimal stress urinary incontinence (SUI) after prostate procedures. Climacturia has been reported in up to 64% of patients following radical prostatectomy (RP). We sought to report the 5-year outcomes from this original cohort to assess long-term safety and effectivity of the mini-jupette sling in the treatment of ED and concomitant mild SUI and/or climacturia. Methods: This is a single-arm, multicenter, retrospective, observational study. We identified patients who were enrolled in the previous multicenter study with post-RP ED and climacturia and/or mild SUI- 2 PADS PER DAY (PPD) and underwent inflatable penile prosthesis (IPP) insertion with simultaneous placement of a mini-jupette sling. Data were collected including current PPD, subjective improvement in climacturia/SUI, complications, need for revision of IPP or additional urinary incontinence surgery, and date of most recent follow-up. SPSS was used for statistical analysis. Results: Of the original 38 patients, 5 have since died and 10 were lost to follow-up with 23/38 (61%) patients available for evaluation of long-term outcomes. The average follow-up time was 59 months (SD =8.8) with a mean age of 69 years (SD =6.8). Most patients (n=21, 91%) had subjective improvement of SUI and climacturia. One patient with persistent bothersome incontinence underwent artificial urinary sphincter (AUS) placement in 2018 with no complications, while the other is still considering a repeat procedure due to minor but persistent SUI. The mean PPD decreased from 1.4 preoperatively to 0.4 at a mean of 5 years of follow-up. Most patients reported satisfaction in their urinary symptoms with 91% and 73% reporting improvement in SUI and climacturia respectively, compared to 86% and 93% respectively in the original series. One (4.3%) patient had an IPP revision for pump malfunction. There were no device infections reported. Conclusions: The mini-jupette sling appears to be a safe and effective procedure with durable improvements in SUI and climacturia at 5 years of follow-up.

Residual penile curvature correction by modeling during penile prosthesis implantation in Peyronie's disease patients.

With the advent of new surgical techniques to treat Peyronie's disease with concomitant erectile dysfunction, there remains a question of whether manual modeling (MM), an older technique, still has a place in the treatment algorithm within penile prosthesis (PP) surgery. While the implantation of a PP often corrects moderate to severe curvature, penile curvature can remain greater than 30°, even when concurrent MM is performed during prothesis implantation. There are new variations of the MM technique that have been recently utilized in the intraoperative and postoperative setting to achieve penile curvature less than 30° when the implant is fully inflated. The inflatable PP, regardless of the specific model of choice, is preferred over the noninflatable PP when utilizing the MM technique. MM should be the first line of treatment for persisting intraoperative penile curvature after the placement of a PP due to its long-term efficacy, noninvasive approach, and significantly low risk of adverse effects.

The Revised PENIS Score and proposal of the PACKAGE Checklist: a meta-epidemiologic study on penile amputation and replantation.

INTRODUCTION: Penile amputation causes severe physical and psychosocial distress. Microsurgical implementation in penile replantation is presumed to be superior to surgical repair. This assumption has been difficult to verify. OBJECTIVES: The purpose of this study was threefold: (1) to produce an updated review of penile replantation, substantiated by the largest sample size to date; (2) to appraise the comparative value of the novel PENIS Score and propose the PACKAGE Checklist, a guide for standardization of future case reports and reviews; and (3) to improve confusing terminology and recommend the standardization of vocabulary. METHODS: A literature review assessed 432 full-text case reports in 20 languages and identified 123 microsurgical and 40 surgical cases of penile replantation. The novel PENIS Score stratified penile amputations based on 5 criteria: position along the shaft, extension through the penis, neurovascular repair, ischemia time and type, and severed edge condition and contamination. For the outcome measurements, a Kendall tau coefficient evaluated the association between each PENIS criterion for short-term postoperative complications and 3 outcome measures: erection, urination, and sensation. RESULTS: Less than half of surgical reports on penile replantation are sufficiently detailed to complete all PENIS Score criteria. The viability of microsurgical and surgical replantation was equivalent at 92% and 94%, respectively. A statistically significant correlation was found between microsurgical repair and the return of sensation but not with nerve repair. Return of sensation with nerve repair was 51%, and microsurgical replantation without nerve repair was 42%; both were significantly higher than the 14% for surgical replantation. Preservation of a skin bridge was associated with a 40% reduction in severe postoperative complications. CONCLUSION: Microsurgical replantation is superior in return of sensation, with or without nerve repair. Implementing the PACKAGE Checklist and PENIS Score will help inform case reports and reviews.

Testosterone Assays.

Challenges to the accurate and precise measurement of testosterone include deficiencies in standardization, variable reference ranges, expenses related to gold standard equipment, and other challenges. Total testosterone remains the most accessible for standard laboratories, while free testosterone and bioavailable testosterone may be useful adjuncts, particularly in men with low borderline testosterone values. Mass spectrometry is the gold standard measurement modality for total testosterone, while equilibrium dialysis followed by direct assessment with a trusted method is the gold standard technique for measuring free testosterone. Although reference ranges may vary, efforts to adapt reference ranges to different populations include age-adjusted values.

Association between Seminal Oxidation-Reduction Potential and Sperm DNA Fragmentation-A Meta-Analysis.

Seminal oxidative stress and sperm DNA damage are potential etiologies of male factor infertility. The present study aims to evaluate the relationship between oxidation-reduction potential (ORP), a measure of oxidative stress, and sperm DNA fragmentation (SDF) by conducting a systematic review and meta-analysis of relevant clinical data. A literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The COVIDENCE tool was used to screen and identify studies evaluating seminal ORP and SDF. Studies (n = 7) that measured seminal ORP and SDF of 3491 semen samples were included in the analysis. The fixed-effects model revealed a significant pooled correlation coefficient (r = 0.24; p < 0.001) between seminal ORP and SDF. Furthermore, subgroup analyses indicated that the pooled correlation coefficient between ORP and sperm chromatin dispersion (SCD) assay was less than other SDF assays (0.23 vs. 0.29). There was a moderate level of heterogeneity (I2 = 42.27%) among the studies, indicating a lack of publication bias. This is the first meta-analysis to reveal a positive correlation between seminal ORP and SDF. Furthermore, this study indicates the role of oxidative stress in the development of sperm DNA damage and thus warrants prospectively exploring the clinical value of these sperm function tests.

MANTA and MANTA-RAy: Rationale and Design of Trials Evaluating Effects of Filgotinib on Semen Parameters in Patients with Inflammatory Diseases.

INTRODUCTION: The phase 2 MANTA and MANTA-RAy studies were developed in consultation with global regulatory authorities to investigate potential impacts of filgotinib, a Janus kinase 1 preferential inhibitor, on semen parameters in men with active inflammatory diseases. Here we describe the methods and rationale for these studies. METHODS AND RATIONALE: The MANTA and MANTA-RAy studies included men (aged 21-65 years) with active inflammatory bowel disease (IBD) and rheumatic diseases, respectively. Participants had no history of reproductive health issues, and the following semen parameter values (≥ 5th percentile of World Health Organization reference values) at baseline: semen volume ≥ 1.5 mL, total sperm/ejaculate ≥ 39 million, sperm concentration ≥ 15 million/mL, sperm total motility ≥ 40% and normal sperm morphology ≥ 30%. Each trial included a 13-week, randomized, double-blind, placebo-controlled period (filgotinib 200 mg vs placebo, up to N = 125 per arm), for pooled analysis of the week-13 primary endpoint (proportion of participants with ≥ 50% decrease from baseline in sperm concentration). All semen assessments were based on two samples (≤ 14 days apart) to minimize effects of physiological variation; stringent standardization processes were applied across assessment sites. From week 13, MANTA and MANTA-RAy study designs deviated owing to disease-specific considerations. All subjects with a ≥ 50% decrease in sperm parameters continued the study in the monitoring phase until reversibility, or up to a maximum of 52 weeks, with standard of care as treatment. Overall conclusions from MANTA and MANTA-RAy will be based on the totality of the data, including secondary/exploratory measures (e.g. sperm motility/morphology, sex hormones, reversibility of any effects on semen parameters). CONCLUSIONS: Despite the complexities, the MANTA and MANTA-RAy studies form a robust trial programme that is the first large-scale, placebo-controlled evaluation of potential impacts of an advanced IBD and rheumatic disease therapy on semen parameters. TRIAL REGISTRATION: EudraCT numbers 2017-000402-38 and 2018-003933-14; ClinicalTrials.gov identifiers NCT03201445 and NCT03926195.

Filgotinib is a treatment for patients with ulcerative colitis and rheumatoid arthritis, and is being studied in other inflammatory diseases. Filgotinib works by blocking Janus kinase 1, an intracellular protein involved in inflammatory signalling processes. We designed the MANTA and MANTA-RAy trials with global health agencies to find out if filgotinib decreases the quality of semen in men with active inflammatory bowel disease (ulcerative colitis or Crohn's disease) (MANTA) or rheumatic disease (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis or non-radiographic axial spondylitis) (MANTA-RAy). This paper describes the design of the two trials.Patients had normal sperm measurements and could not have had previous reproductive health issues. Nearly 250 patients were included in each trial. In both MANTA and MANTA-RAy, half of the patients were treated with 200 mg of filgotinib once a day for 13 weeks, and the other half with placebo. We determined if any patients had a decrease in number of sperm cells per millilitre (sperm concentration) by at least half after 13 weeks of treatment. We then monitored any patients who had such a decrease in sperm concentration for up to 52 weeks (while they received standard of care treatment) or until the decrease was reversed.The conclusions from the trials will be in a different paper and will be based on all the final data, including changes in sex hormones. This is the first large-scale clinical trial programme to measure the effect of a treatment on sperm in men with inflammatory bowel disease or rheumatic diseases.

Diagnostic criteria for enduring sexual dysfunction after treatment with antidepressants, finasteride and isotretinoin.

BACKGROUND: A set of enduring conditions have been reported in the literature involving persistent sexual dysfunction after discontinuation of serotonin reuptake inhibiting antidepressants, 5 alpha-reductase inhibitors and isotretinoin. OBJECTIVE: To develop diagnostic criteria for post-SSRI sexual dysfunction (PSSD), persistent genital arousal disorder (PGAD) following serotonin reuptake inhibitors, post-finasteride syndrome (PFS) and post-retinoid sexual dysfunction (PRSD). METHODS: The original draft was designed using data from two published case series (Hogan et al., 2014 and Healy et al., 2018), which represent the largest public collections of data on these enduring conditions. It was further developed with the involvement of a multidisciplinary panel of experts. RESULTS: A set of criteria were agreed upon for each of the above conditions. Features of PSSD, PFS and PRSD commonly include decreased genital and orgasmic sensation, decreased sexual desire and erectile dysfunction. Ancillary non-sexual symptoms vary depending on the specific condition but can include emotional blunting and cognitive impairment. PGAD presents with an almost mirror image of unwanted sensations of genital arousal or irritability in the absence of sexual desire. A new term, post-SSRI asexuality, is introduced to describe a dampening of sexual interest and pleasure resulting from a pre-natal or pre-teen exposure to a serotonin reuptake inhibitor. CONCLUSIONS: These criteria will help in both clinical and research settings. As with all criteria, they will likely need modification in the light of developments.

Hematospermia Etiology, Diagnosis, Treatment, and Sexual Ramifications: A Narrative Review.

INTRODUCTION: Hematospermia (HS) is the presence of blood in ejaculatory fluid. It is a rare condition that is historically idiopathic or associated with sexual behavior. Technological advances have identified many of the etiologies behind HS, improving treatment. Though often benign, HS remains a source of considerable sexual anxiety for patients. Few papers have outlined a diagnostic and therapeutic approach to HS, and none have explicitly addressed its sexual consequences. OBJECTIVES: To provide a comprehensive overview of HS, emphasizing its sexual ramifications. METHODS: A PubMed literature search was performed through May 2021 to identify all relevant publications related to etiology, diagnosis, treatment, and sexual effects of HS. Original research and reviews were analyzed, and pertinent studies were included in this review. RESULTS: Iatrogenic interventions (eg, transrectal ultrasound-guided prostate biopsies) are the most common cause of HS. Infection and/or nonspecific inflammation is the most common non-iatrogenic etiology. Malignancies, including prostate, testicular, and other genitourinary cancers, are rarely the cause of HS. Diagnostic approaches to HS can be organized according to patient age (less than or greater than 40 years old), persistence of bleeding, and the presence/absence of concerning symptoms. Though HS often spontaneously resolves, treatment may require various medications (eg, antibiotics, anti-inflammatories) or surgical interventions. HS has several sexual ramifications, including libido-affecting anxiety, social repercussions from sexual partners and non-sexual affiliates, increased risk of erectile dysfunction or transmission of sexual infections, and compromised fertility, especially when cryopreservation is utilized. CONCLUSION: HS may significantly affect sexual health through several mechanisms, though there is a paucity of formal data on this subject. Further research is needed to fully understand the severity and extent of HS's effect on sexual well-being, especially in those with refractory bleeding. Drury RH, King B, Herzog B, et al.

Global Trends in Prevalence, Treatments, and Costs of Penile Prosthesis for Erectile Dysfunction in Men.

CONTEXT: Penile prosthesis is a durable and effective treatment for erectile dysfunction (ED). Even as other treatment options for ED have been brought to market, penile prosthetic surgery remains a mainstay for urologists treating ED. No systematic study has yet summarized the global trends in penile prosthetic surgery. OBJECTIVE: To systematically review studies of trends in penile prosthetic surgery to determine global movements in implantation rates, malleable versus inflatable prosthetic surgery, inpatient versus outpatient implantation surgery, proportion of men with ED undergoing penile prosthetic surgery, and prosthetic cost. EVIDENCE ACQUISITION: A systematic review of MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials.gov was performed for studies assessing trends in penile prosthetic surgeries and costs associated with penile prosthetic device and inclusive surgical costs. EVIDENCE SYNTHESIS: Twenty-seven studies were identified during the systematic review, comprising 447,204 penile prosthetic surgeries reported from 1988 to 2019. A trend analysis demonstrates that rates of penile prosthetic surgery declined dramatically in the late 1980s and early 1990s, but have demonstrated modest growth since the mid-2000s. Outpatient inflatable penile prosthetic surgery has strongly trended upward. Costs of penile prosthetic device have matched the rate of inflation, but inclusive surgical cost has radically outpaced inflation. Growth has mainly been seen in the USA, with a more modest global growth. CONCLUSIONS: Penile prosthesis remains a viable option for the treatment of ED. Trends such as outpatient surgery and inflatable penile prosthesis placement may be driving the recent steady growth of penile prosthetic surgeries, but surging inclusive surgical cost may present a barrier for some patients without insurance coverage. PATIENT SUMMARY: Penile prostheses continue to be an important treatment for erectile dysfunction. While the volume of penile prosthetic surgeries dropped when phosphidiesterase-5 inhibitors became available, prosthetic surgery is becoming more patient centric, as seen by increases in inflatable prosthetic placement and outpatient surgery.

Revelations on Men Who Seek Penile Augmentation Surgery: A Review.

INTRODUCTION: Men with normal penis size sometimes mistakenly believe they have below average penile dimensions and often seek out treatment. Many men suffer from significant anxiety regarding this perceived defect. In this review, we evaluate the current literature of psychological, medical, and surgical treatment options for men with a complaint of a small penis. OBJECTIVE: To review the current practice for treatment of men presenting for penile augmentation surgery. METHODS: A literature review was conducted, using PubMed to identify current studies regarding penile enhancement. Search terms included "penile enhancement," "small penis anxiety," "small penis syndrome," "body dysmorphic disorder," and "penile augmentation." RESULTS: The literature consistently reveals that men who seek out penile augmentation surgery usually have normal penile dimensions. There are limited published data on the practice of penile lengthening surgery or procedures to increase penile girth. New techniques have expanded on suspensory ligament release, such as tissue grafting and flaps. Structured psychological counseling continues to be the recommended initial standard of care for these men. CONCLUSION: Many social forces have increased the perception among men that their penis size is inadequate. This increases anxiety and can lead to psychological disorders such as Penile Dysmorphic Disorder and Small Penis Syndrome. Men who undergo penile enhancement are often not satisfied with the results and may develop complications. Soubra A, Natale C, Brimley S, et al.

Options for Masculinizing Genital Gender Affirming Surgery: A Critical Review of the Literature and Perspectives for Future Directions.

INTRODUCTION: Masculinizing genital gender affirmation surgery (MgGAS) has witnessed significant change in recent years. With the increasing number of patients seeking out GAS, optimization of techniques is mandated. OBJECTIVES: To critically review the evolution of MgGAS, in a manner that encompasses the history and scope of the procedures, including phalloplasty with and without urethral lengthening, metoidioplasty with and without urethral lengthening, penile prosthesis placement, scrotoplasty, testicular prosthesis placement, vaginectomy, and hysterectomy. METHODS: A comprehensive literature review was conducted in accordance with PRISMA guidelines, using PubMed. For our search, we generated a comprehensive list of MgGAS, combined with synonyms for GAS to ensure that articles included transgender cohorts. We identified a total of 547 articles from the search terms. Of these articles, 144 abstracts were relevant. Among these abstracts, 108 manuscripts were reviewed in full of which 98 were acceptable for inclusion. We excluded non-English-language studies without translation and studies that did not describe primary gGAS (eg, revision surgeries). RESULTS: The evolution of MgGAS encompasses mostly refinements of pre-existing procedures, rather than new techniques or "watershed" procedures. The literature is somewhat lacking in outcomes-reporting that identifies the specific anatomy and surgical technique(s) used during gGAS. Without clarity regarding anatomy and technique, it is not feasible to compare surgical outcomes. CONCLUSION: There is no ideal MgGAS; thus, it is critical that the physician assist the patient in understanding the outcomes and potential morbidity of the procedures to make the most informed decision. We envision that the future of MgGAS will advance with refinement of surgical techniques that minimize complications, improvement of tissue therapeutic technologies, new surgical tools and prosthetics designed for gGAS, advances in aftercare, and an immense selection of surgical options.

Tips and tricks in the management of inflatable penile prosthesis infection: A review.

OBJECTIVE: To review the management of inflatable penile prosthesis (IPP) infection.Methods: The 'gold-standard' treatment for medication-refractory erectile dysfunction is the IPP, wherein the most dreaded complication is infection. To prevent and manage an infected IPP requires a strict protocol during the pre-, intra-, and postoperative course. A variety of techniques and antibiotics are used in conjunction with IPP implantation to prevent contamination. This modified Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) review of the literature examines the current practices by leading urologists in the management of IPP infection, as well as provides insights for improved patient outcomes. RESULTS: : Patient selection is important to reduce IPP infections, and those with risk factors need to be optimised prior to surgery. Proper antibiotic prophylaxis includes pre-, intra-, and postoperative administration. As most infections derive from normal skin flora, every measure must be taken to sterilise the skin and avoid direct device skin contact. Up to 3% of virgin IPPs develop infections and this number increases to 18% in revision cases. Antibiotic coverage depends on the presenting microbe, which can vary significantly between patients. CONCLUSIONS: : A greater success in IPP implantation can be attributed to appropriate prophylaxis, field sterilisation, and surgical technique. For those implants that do become infected, often erectile function can be preserved by immediate antibiotic coverage combined with salvage procedures.

Reviewing the evidence for shockwave- and cell-based regenerative therapies in the treatment of erectile dysfunction.

Erectile dysfunction (ED) is both a common and complex disease process. Existing ED treatments do not always achieve adequate results. There is clinical interest in employing regenerative therapies, including low-intensity extracorporeal shockwave therapy (Li-ESWT), platelet rich plasma (PRP), and stem cell therapy (SCT), in the treatment of ED as adjunct or alternative treatments. Here, we present evidence for emerging shockwave- and cell-based regenerative therapies for the treatment of ED following a thorough review of the existing PubMed literature pertaining to Li-ESWT, PRP, and SCT in relation to the treatment of ED. Li-ESWT causes microtrauma in tissue that hypothetically upregulates angiogenesis and recruits stem cells. Several large-scale systematic reviews and meta-analyses have reported that Li-ESWT improved ED in humans. Additionally, evidence has commenced to show that Li-ESWT may be effective against two recognized and complex etiologies of ED: diabetic and neurogenic. PRP delivers an autologous sample rich in growth factors to damaged tissue. Animal model studies have demonstrated improved erectile function recovery as well as preservation of cavernous nerve axons. Studies with PRP in humans are limited. SCT utilizes the regenerative potential of stem cells for healing of damaged tissue. In the treatment of ED, SCT has been used in the setting of diabetic and post-prostatectomy ED. Results of human studies are varied, although SCT treatments did result in increased erectile rigidity with some patients recovering the ability to achieve penetration. While these regenerative therapies show potential to augment the current treatment regimen for ED, there is a paucity of evidence to support the safety and efficacy of these treatments. Further research is necessary to define the role of these alternative therapies in the treatment of ED.
