The Application of Hyaluronic Acid Injections in Functional and Aesthetic Andrology: A Narrative Review.

Hyaluronic acid (HA) is a glycosaminoglycan widely utilised in different fields of medicine. We aimed to provide a comprehensive overview of the scientific evidence on the use of HA in andrology. A review of the literature to identify pertinent studies concerning the use of HA in andrology was carried out on the Medline, EMBASE, and the Cochrane databases, with no time restriction up to December 2022. Penile girth enlargement (PGE) using HA proved to be safe and effective in enhancing the diameter of the penis, with durable and satisfactory outcomes in long-term follow-up. Injection of HA in the glans seems to represent an alternative treatment option for those patients with premature ejaculation (PE) who fail to respond to conventional medications. HA intra-plaque injections represent a valid option which may contribute to restore sexual activity in patients with Peyronie's disease (PD). The adoption of HA filler injections should always be tailored to the patient's peculiar anatomy and underlying condition. More robust evidence is required to achieve a uniformed consensus regarding the use of HA in andrology, and further efforts should continue to improve the current injection techniques and HA products.

The Complex Interplay between Serum Testosterone and the Clinical Course of Coronavirus Disease 19 Pandemic: A Systematic Review of Clinical and Preclinical Evidence.

Since the beginning of the coronavirus disease 19 (COVID-19) pandemic, efforts in defining risk factors and associations between the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), clinical, and molecular features have initiated. After three years of pandemic, it became evident that men have higher risk of adverse outcomes. Such evidence provided the impetus for defining the biological fundaments of such a gender disparity. Our objective was to analyze the most recent literature with the aim of defining the relationship between COVID-19 and fertility, in particular, we assessed the interplay between SARS-CoV-2 and testosterone in a systematic review of literature from December 2019 (first evidence of a novel coronavirus in the Hubei province) until March 2022. As a fundamental basis for understanding, articles pertaining preclinical aspects explaining the gender disparity (n=9) were included. The main review categories analyzed the risk of being infected with SARS-CoV-2 according to testosterone levels (n=5), the impact of serum testosterone on outcomes of COVID-19 (n=23), and the impact SARS-CoV-2 on testosterone levels after infection (n=19). Preclinical studies mainly evaluated the relation between angiotensin-converting enzyme 2 (ACE2) and its androgen-mediated regulation, articles exploring the risk of COVID-19 according to testosterone levels were few. Although most publications evaluating the effect of COVID-19 on fertility found low testosterone levels after the infection, follow-up was short, with some also suggesting no alterations during recovery. More conclusive findings were observed in men with low testosterone levels, that were generally at higher risk of experiencing worse outcomes (i.e., admission to intensive care units, longer hospitalization, and death). Interestingly, an inverse relationship was observed in women, where higher levels of testosterone were associated to worse outcomes. Our finding may provide meaningful insights to better patient counselling and individualization of care pathways in men with testosterone levels suggesting hypogonadism.

Prospective Cross-Sectional Evaluation of Penile Helicine Circulation by Power Doppler During Dynamic Ultrasound in Veno-Occlusive Erectile Dysfunction.

OBJECTIVE: To evaluate the usefulness of Power Doppler to improve the diagnostic work up of veno-occlusive erectile dysfunction patients. MATERIALS AND METHODS: Patients affected by erectile dysfunction, mean IIEF 5 = 13.5 (12-17) for at least 6 months, were enrolled in a prospective cross-sectional study. All patients underwent Dynamic Power Doppler after intracavernous injection of vasoactive drugs (PGE1 20 mcg and Papaverine 6 mg). Poor responders' patients subsequently underwent to cavernosometry to get a full assessment of the vascular framework. RESULTS: 202 patients (mean age 46 years), were included in the study. 96 subjects (47.5%) who did not adequately respond to the intracavernous injection -test, subsequently underwent to cavernosometry. In 42 of 96 patients (43.7%) cavernosometry was positive for veno-occlusive dysfunction. In a total of 160 patients who did not have veno-occlusive dysfunction (54 with negative cavernosometry + 106 intracavernous injection-test responders), the Power Doppler was normal in 126 (78.8%) and pathological in 34 (21.3%) in terms of steric conformation of "low flow" vessels corresponding to the Cavernosal Terminal Unit. The diagnostic sensitivity of Power Doppler towards veno-occlusive dysfunction was found to be 52.4% (Positive Predictive Value: 39.3%), the specificity was 78.8% (Negative Predictive Value: 86.3%) and the total diagnostic accuracy was equal to 73.3%. CONCLUSION: Collected data evidenced that patients who reported altered morphological features of the Cavernosal Terminal Unit had an approximately 4-fold greater risk of having veno-occlusive dysfunction compared to patients who had normal Power Doppler features (OR = 4.076; 95% CI: 1.996-8.327).

Li-Eswt improves hemodynamic parameters thus suggesting neoangiogenesis in patients with vascular erectile dysfunction.

Extracorporeal treatment with low intensity shock-wave therapy (LI-ESWT) is a recently introduced non-invasive method which purposes the restoration of the pathophysiological alterations at the base of vasculogenic ED in male patients. The evidence in favour of the neoangiogenic potential of this treatment derived from in vitro studies and on animal models. The purpose of this study, in which the Power Doppler method was applied, is to demonstrate 'objectively' the real efficacy of LI-ESWT at the level of the microcirculation of the corpora cavernosa (neoangiogenesis) in patients affected by vasculogenic ED. Data from this study show, for the first time, that LI-ESWT treatment promotes neovascularisation of the functional arteries in patients affected by vasculogenic ED.

Outcomes and predictive factors of successful salvage microdissection testicular sperm extraction (mTESE) after failed classic TESE: results from a multicenter cross-sectional study.

Microdissection testicular sperm extraction (mTESE) has been proposed as a salvage treatment option for men with a previously failed classic TESE (cTESE), but data are scarce. We aimed to assess the outcome of and potential predictors of successful salvage mTESE in a cohort of men previously submitted to unfruitful cTESE. Data from 61 men who underwent mTESE after a failed cTESE between 01/2014 and 10/2020, at 6 tertiary-referral centres in Italy were analysed. All men were investigated with semen analyses, testicular ultrasound, hormonal and genetic blood testing. Pathological diagnosis from TESE was collected in every man. Descriptive statistics and logistic regression models were used to investigate potential predictors of positive sperm retrieval (SR+) after salvage mTESE. Baseline serum Follicle-Stimulating hormone (FSH) and total testosterone levels were 17.2 (8.6-30.1) mUI/mL and 4.7 (3.5-6.4) ng/mL, respectively. Sertoli-cell-only syndrome (SCOS), maturation arrest (MA) and hypospermatogenesis were found in 24 (39.3%), 21 (34.4%) and 16 (26.2%) men after cTESE, respectively. At mTESE, SR+ was found in 30 (49.2%) men. Patients with a diagnosis of hypospermatogenesis had a higher rate of SR+ (12/16 (75%)) compared to MA (12/21 (57.1%)) and SCOS (6/24 (25%)) patients at mTESE (p < 0.01). No clinical and laboratory differences were observed between SR+ and SR- patients at mTESE. There were no significant complications after mTESE. At multivariable logistic regression analysis, only hypospermatogenesis (OR 9.5; p < 0.01) was independently associated with SR+ at mTESE, after accounting for age and FSH.In conclusion, salvage mTESE in NOA men with previous negative cTESE was safe and promoted SR+ in almost 50%. A baseline pathology of hypospermatogenesis at cTESE emerged as the only independent predictor of positive outcomes at salvage mTESE.

Clinical use of hyaluronic acid in andrology: A review.

BACKGROUND: Hyaluronic acid is a glycosaminoglycan widely used in the fields of orthopedics, ophthalmology, and aesthetic medicine due to its significant ability to reduce the synthesis of pro-inflammatory proteins and its activity against oxidative stress, a feature of many degenerative illnesses. OBJECTIVES: The objective of the present review is to provide a comprehensive narrative review of the most recent literature on the use of hyaluronic acid in andrology in order to facilitate the use of this therapeutic device in the common clinical practice of many physicians. Specific conditions covered in the review are Peyronie's disease, premature ejaculation, and penile enlargement. MATERIALS AND METHODS: A broad and comprehensive literature search included Medline, EMBASE, and the Cochrane Libraries, with no time restriction up to December 2020 and restricted to English language publications. Unpublished studies were not included. The study was registered as "The role of hyaluronic acid in andrology: A systematic review and meta-analysis" in PROSPERO with the ID CRD42021223416. DISCUSSION AND CONCLUSION: Hyaluronic acid is a valid choice for the treatment of Peyronie's disease in terms of the resolution of the acute phase of the disease and of contributing to stabilizing the disease as a bridge to potential surgery. Data, furthermore, suggest that hyaluronic acid is frequently associated with an overall clinical improvement, allowing the patient to resume normal sexual activity. With regard to premature ejaculation, data suggests hyaluronic acid-based treatments were effective in prolonging intra-vaginal ejaculation time. Furthermore, hyaluronic acid was found to be safe and well-tolerated, with main adverse events limited to local discomfort, ecchymosis, papule formation, and glans numbness, all of which were reported to resolve spontaneously. Last, with regard to penile enlargement, the overall perception of experts is that hyaluronic acid may be an extremely well-tolerated compound with potential for application in specific areas of male sexual health that are often neglected as compared to more common, and relatively simpler to treat, conditions.

COVID-19 disease in clinical setting: impact on gonadal function, transmission risk, and sperm quality in young males.

OBJECTIVES: We want to evaluate the possible presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in semen samples and semen quality, looking for a possible relationship between the infectious disease and fertility. METHODS: In this prospective study, we enrolled 15 consecutive men (age 18-50 years) with positive oropharyngeal swab to SARS-CoV-2 and classified, according to WHO criteria, in mild to moderate disease. A semen sample was collected to detect SARS-CoV viral RNA by the automated Real-Time PCR ELITe InGenius® system and the GeneFinderTM COVID-19 Plus RealAmp Kit assay (ELITechGroup, France). Analysis of semen characteristics was performed according to WHO laboratory manual 5th ed. for the examination and processing of human semen. Blood samples for the dosage of hormonal assay, procalcitonin, interleukin 6, C-reactive protein were obtained. RESULTS: SARS-CoV-2 RNA has not been detected in semen samples from any of the subjects analysed. Sperm analysis exhibited abnormal seminal values in 14 out of 15 patients (93.3%). Furthermore, no difference was detected regarding sperm quality between mild and moderate SARS-CoV-2 patients. No alteration in the inflammatory indices was observed in the studied population, as well gonadotropins and testosterone levels. CONCLUSIONS: COVID patients studied exhibits alteration of the seminal fluid both in microscopic and macroscopic characteristics such as hypoposia and increased viscosity, which have not been detected in previous studies. The presence of viral RNA within the seminal fluid was excluded.

Feasibility of local anaesthesia for varicocele correction in one-day-surgery setting. A single center experience.

OBJECTIVE: In this study, we compared postoperative outcomes of patients submitted to varicocele correction under general or local anesthesia at a single center. METHODS: All patients underwent varicocele surgical treatment with the Colpi-modified Marmar subinguinal technique. They were managed with either general (Group A) or local with ileo-inguinal and ileo-hypogastric nerves block (Group B) anesthesia. The two groups were compared in terms of timing of discharge and post-operative pain as assessed with the numeric rating scale (NRS) at both rest and movement (NRSm). § Results: Overall, 63 patients were included with a mean (SD) age of 25 years ± 5 yrs. The NRS mean score was significantly lower for Group B during the first 4 days after surgery at both rest and movement (all p < 0.05). Patients receiving local anesthesia showed a faster time to first urination (210 vs. 240 min; p = 0.02), although the time to discharge was comparable between the two groups (250 vs. 250 min). CONCLUSIONS: These results suggest that local anetshesia for varicocele surgical treatment is feasible and provide better pain control and faster recovery after surgery.

Low intensity shockwave therapy in combination with phosphodiesterase-5 inhibitors is an effective and safe treatment option in patients with vasculogenic ED who are PDE5i non-responders: a multicenter single-arm clinical trial.

Low-intensity shockwave therapy (Li-ESWT) has been shown to be an effective and safe treatment for vasculogenic erectile dysfunction (ED). We aim to evaluate the effectiveness and safety of LiESWT in treating patients affected from vasculogenic ED who did not respond to oral treatment with Phosphodiesterase 5 inhibitors (PDE5-i). It is a multicentric open-label prospective study, in a cohort of patients non-responders to PDE-5i. Li-ESWT was performed in an outpatient setting by using the following schedule: 3000 shockwaves with an energy of 0.25 mJ/mm2 and a frequency of 4-6 Hz, twice a week for 3 weeks. International Index of Erectile Function, Erection Hardness Score and Sexual Quality of Life-Male questionnaires, and penile doppler ultrasound (PDU) are the outcome measurements. The Student t-test or Wilcoxon signed-rank test were applied to compare variables, with results considered statistically significant at p < 0.05. 106 (97.2%) completed treatment and performed follow-up visit after 4 weeks. At follow up visit, the mean IIEF-EF increased by 8.6 points (13.47 ± 4.61 vs 22.07 ± 5.27; p < 0.0001). A clinically significant improvement of IIEF-EF was achieved in 75 patients (70.7%). An EHS score ≥ 3, sufficient for a full intercourse, was reported by 72 patients (67.9%) at follow-up visit. 37 (34.9%) patients reported a full rigid penis (EHS = 4) after treatment. Li-ESWT treatment was also able to improve quality of life (SQOL-M: 45.56 ± 8.00 vs 55.31 ± 9.56; p < 0.0001). Li-ESWT significantly increased mean PSV (27.79 ± 5.50 vs 41.66 ± 8.59; p < 0.0001) and decreased mean EDV (5.66 ± 2.03 vs 1.93 ± 2.11; p < 0.0001) in PDU. Combination of Li-ESWT and PDE5-i represents an effective and safe treatment for patients affected from ED who do not respond to first line oral therapy.

Rates of hypogonadism forms in Klinefelter patients undergoing testicular sperm extraction: A multicenter cross-sectional study.

INTRODUCTION AND OBJECTIVES: Adult patients with Klinefelter syndrome (KS) may present with testicular volume loss and a decrease in circulating testosterone (T) levels. However, the actual rate of hypogonadism in adult KS men is unknown. We aimed to (a) assess the prevalence of different forms of hypogonadism in a cohort of KS patients with non-obstructive azoospermia (NOA); and (b) investigate potential preoperative predictor of positive sperm retrieval (SR) at surgery in the same cohort of men. METHODS: Complete data from 103 KS men with NOA who underwent testicular sperm extraction (TESE) between 2008 and 2019 at five centers were analyzed. Comorbidities were scored with the Charlson Comorbidity Index (CCI). Patients were categorized into four groups of hypogonadism as follows: eugonadism [normal total T (tT) (≥3.03 ng/mL) and normal luteinizing hormone (LH) (≤9.4 mUI/mL)], secondary hypogonadism [low tT (≤3.03 ng/mL) and low/normal LH (≤9.4 mUI/mL)], primary hypogonadism [low tT (≤3.03 ng/mL) and elevated LH (≥9.4 mUI/mL)], and compensated hypogonadism [normal tT (≥3.03 ng/mL) and elevated LH (≥9.4 mUI/mL)]. Descriptive statistics tested the association between clinical characteristics and laboratory values among the four groups. RESULTS: Median (IQR) patients age was 32 (24, 37) years. Baseline follicle-stimulating hormone and tT levels were 29.5 (19.9, 40.9) mUI/mL and 3.8 (2.5, 11.0) ng/mL, respectively. Eugonadism, primary hypogonadism, and compensated hypogonadism were found in 16 (15.6%), 34 (33.0%), and 53 (51.4%) men, respectively. No patients had secondary hypogonadism. Positive SR rate at TESE was 21.4% (22 patients); of 22, 15 (68.2%) patients underwent assisted reproductive technology and five (22.7%) ended in live birth children. Patients' age, BMI, CCI, FSH levels, and positive SR rates were comparable among hypogonadism groups. No preoperative parameters were associated with positive SR at logistic regressions analysis. CONCLUSIONS: Findings from this cross-sectional study showed that 15.6% of adult KS men have normal tT values at presentation in the real-life setting. Most KS patients presented with either compensated or primary hypogonadism. Sperm retrieval rates were not associated with different forms of hypogonadism.

Sperm retrieval rates in non-mosaic Klinefelter patients undergoing testicular sperm extraction: What expectations do we have in the real-life setting?

BACKGROUND: A recent meta-analysis (Human Reproduction Update 23, 2017 and 265) reported positive sperm retrieval rates (SRR) in 50% of patients with Klinefelter syndrome (KS) undergoing testicular sperm extraction (TESE). However, these results do not reflect the rates of SR that we observe in clinical practice. We assessed the rate and potential predictors of SR in Klinefelter patients in the real-life setting. MATERIALS AND METHODS: We reviewed clinical data of 103 KS men who underwent TESE between 08/2008 and 03/2019 at five tertiary referral Andrology centers. Patients underwent testis ultrasound, hormonal evaluation, and genetic testing. All patients were azoospermic based on the 2010 WHO reference criteria. Conventional TESE (cTESE) or microsurgical TESE (mTESE) was performed based on the surgeon's preference. We used descriptive statistics and logistic regression models to describe the whole cohort. RESULTS: Median (IQR) patient's age was 32 (24-37) years. Baseline serum FSH and total testosterone levels were 29.5 (19.9-40.9) mUI/mL and 3.8 (2.5-11.0) ng/mL, respectively. Conventional TESE and mTESE were performed in 38 (36.5%) and 65 (63.5%) men, respectively. The sperm retrieval rate was 21.4% (22/103 men). Fifteen patients used spermatozoa for ICSI and five ended in live birth children. Patients with positive SR were similar to those with a negative TESE in terms of clinical, hormonal, and procedural parameters (all P > .05). Logistic regression analyses confirmed the lack of association between clinical, hormonal, and procedural parameters with SR outcome. DISCUSSION: Given the conflicting results in the literature regarding SRR in KS, patients should be carefully counseled regarding TESE outcomes based on data from published literature and local results. CONCLUSIONS: In the real-life setting, we observed a lower SRR (21.4%) than that reported in meta-analyses in our cohort of KS patients. No associations between clinical, hormonal, and procedural variables with TESE success were found.

A "real life" investigation on the prescriptive habits among Italian andrologists: The "CONSER" survey from Italian Society of Andrology (SIA) on Sildenafil oral film.

Even if oral type 5 phosphodiesterase inhibitors (PDE5i) seem an effective treatment for erectile dysfunction (ED), the drop-out is high among patients. For this reason, pharmaceutical companies are encouraged to develop new administration routes, such as the orally disintegrating film. The aim of this study was to analyse the prescription habit of Italian andrologists affiliated to Italian Society of Andrology (SIA) in the era of new oro-dispersible formulation of sildenafil. A 12-items dedicated questionnaire has been distributed to 77 urologists andrologists. As a result of the questionnaire, sildenafil is still the preferred drug of Italian andrologists as it is considered the safest and the most effective. It combines the speed of action and the discretion of the intake that are very important issues for the adherence to the treatment according to the Italian sample. Physicians have also reported the positive feedback of the patients taking sildenafil film as they consider the oro-dispersible formulation either comparable or superior to the old tablet. In conclusion this new formulation has given a new life to an old molecule like sildenafil, and Italian andrologists considered this new pharmaceutical formulation as a good tool to improve the patient's adherence to the treatment and quality of life.

The intra-meatal application of alprostadil cream (Vitaros®) improves drug efficacy and patient's satisfaction: results from a randomized, two-administration route, cross-over clinical trial.

To investigate the efficacy, tolerability, and patient's preference of alprostadil cream for topical use administered within the urethral meatus versus the standard administration route, in erectile dysfunction (ED) treatment. Seventy-one patients (mean age 59.7 ± 9.0 years) affected by ED were analyzed in this multicenter, randomized, two-administration routes, cross-over trial. All patients received a single dose of alprostadil cream applying the dispenser to the tip of the penis (without contacting the urethral meatus) (Standard administration route or ST.AR) alternating with a single dose of alprostadil cream applying the dispenser within the urethral meatus (New administration route or NEW.AR) separated by a one-week washout period, according to randomization. The primary objective of the study was to evaluate the change in International Index of Erectile Function (IIEF-5) total score from baseline to the control visit by comparing the ST.AR and NEW.AR. Secondary objectives of the study were to compare the different methods of administration by evaluating the change in the Sexual Encounter Profile (SEP-2 and SEP-3) questionnaire score and the Patient Reported Outcomes (PROs) by scoring the Patient Self-Assessment of Erection (PSAE) questionnaire. The treatment safety profile was assessed by analysis of adverse events (AEs). Based on the study findings it is evident that the NEW.AR is more efficacious than the ST.AR in improving IIEF-5 and SEP scores from baseline to control visit (IIEF-5: +3.8 vs +6.3; p < 0.001; positive response to SEP-2: 10 vs 27; p = 0.002) and in terms of PSAE (a significant improvement from the baseline in 31% of patients; p < 0.001). As regards the safety profile, no difference in terms of local and systemic side effects was found.

Differences in Cavernosal Artery Parameters According to Different Anatomic Sampling Locations During the Diagnosis of Vascular Erectile Dysfunction Using Duplex Ultrasound.

OBJECTIVE: To establish a standard location for examining penile cavernosal arteries (CAs) using dynamic duplex Doppler ultrasound (PDDU) examination in the diagnosis of non-arterial erectile dysfunction (ED) or arterial insufficiency. PATIENTS AND METHODS: Two groups of 105 patients each were enrolled. The first group (age 56.3 ± 6.0 years) displayed clinical patterns of arterial insufficiency; the second group (age 35.2 ± 4.7 years) displayed clinical patterns of non-arterial ED. The patients had their peak systolic velocity (PSV), end-diastolic velocity (EDV), resistive index (RI = PSV - EDV/PSV × 100), and acceleration time of the CAs measured using PDDU at the crura and at the midpoint between the penoscrotal junction and the coronal sulcus (mid penis). Intra- and interoperator variability were assessed. The PSV, RI, acceleration time, and EDV data obtained from the penoscrotal junction or from the "mid penis" in group 1 and in group 2 were compared using analysis of variance. RESULTS: The PSV, EDV, and acceleration time were significantly higher when measured at the crura penis than when measured at the "mid penis" in both groups, whereas the RI was higher at the "mid penis" than at the "crura." Thus, arterial ED was better diagnosed with the data from the mid penis, whereas non-arterial ED was better diagnosed at the "crura." CONCLUSION: The location of the sampling site of the CAs using PDDU is critical for a correct diagnosis of ED.

Testicular histology may predict the successful sperm retrieval in patients with non-obstructive azoospermia undergoing conventional TESE: a diagnostic accuracy study.

PURPOSE: The present study sought to determine the diagnostic accuracy of FSH level, testicular volume, and testicular histology in predicting the successful sperm retrieval (SSR) in a large cohort of patients with non-obstructive azoospermia undergoing conventional testicular sperm extraction (TESE). METHODS: We retrospectively evaluated 356 patients with non-obstructive azoospermia between June 2004 and July 2009. Binary logistic regression was used to evaluate the diagnostic accuracy of our predicting model, identifying sperm retrieval rate as binary dependent variable. The predictive accuracy of all variables individually evaluated was quantified with area under curve (AUC) estimates derived from receiver operating characteristic (ROC) curve. RESULTS: The mean patients' age was 36.8 years. Testicular sperm were retrieved in 158 out of 356 patients (44.3 %). Histological diagnosis of Sertoli cell only syndrome (SCO) was obtained in 216 patients (60.6 %), while 55 patients (15.4 %) had maturation arrest (MA) and 85 (23.8 %) had hypospermatogenesis (HYPO). The binary logistic regression model was statistically significant (χ 2 = 96.792, p < 0.0001) and correctly classified 72.8 % of cases with 46.8 % sensitivity and 93.4 % specificity, positive predictive value (PPV) 85.06 %, negative predictive value (NPV) 68.7 %, +likelihood ratio (LR) 7.13, and -LR 0.57. Only testicular histology was significant to the model, while FSH and testicular volume were not. Sperm retrieval rate (SRR) was significantly higher in patients with HYPO compared to patients with SCO or MA (88.2 vs 30.5 and 30.9 %, respectively, p < 0.0001) CONCLUSIONS: This study demonstrates that including testicular histology in a model for predicting sperm retrieval increases its diagnostic accuracy. As histology is not available prior to TESE, this model applies only to patients with previous testicular surgery.

Penile vascular diagnostic categorization using penile duplex Doppler ultrasound: Differences in vascular hemodynamics parameters by differences in anatomic sampling location.

OBJECTIVES: In 2013 the International Society for Sexual Medicine(ISSM) published the guidelines regarding the standard operating procedure (SOP) for penile duplex Doppler ultrasound (PDDU). Although ISSM-SOP have given important strides in reducing interobserver variability in PDDU by procedural protocol and parameters these guidelines do not address the anatomic location along the penis at which hemodynamic measurements have to be done. In our opinion a "double sampling" may be interesting to detect the arteriogenic or venogenic nature of the erectile dysfunction (ED). In particular sampling measurements at the "crus" (at the level of the peno-scrotal junction) may be significative for detection of veno-occlusive dysfunction (VOD),whereas an evaluation at "mid penis" (1/2 distance between peno-scrotal junction and coronal sulcus), may be useful to diagnose an arterial insufficiency (AI). MATERIAL AND METHODS: We evalued 90 men, mean age 56.3, affected with ED of medium degree, responder to PDE5-I that urdergone to PDDU and also responder after pharmacologic intracavernosal injection (PII)of prostaglandin E1 20 mcg, with rigid erection and normal maintenance. We moreover evalued 90 men in youthful age (mean 35.2), in absence of vascular risk factors, no responder to PDE5-I that undergone to PDDU by PII at high dosage (bimix: prostaglandin E1 20 mcg, papaverine 20 mg). RESULTS: In the first pool the sampling at "mid penis" resulted significative for arterial insuffciency (AI) in 81% (73), in presence of normal or borderline end diastolic velocity (EDV). Sampling at the "crus" resulted negative for VOD in 90% (81). In the second pool, 66.6% (60) resulted responder with rigid erection and normal maintenance in presence of normal hemodynamic parameters: peak systolic velocity (PSV) and end diastolic velocity (EDV) both at the "crus" and at "mid penis" sampling. 33.4% (30) responded with a semirigid erection and manifested a constant deficit of maintenance; at the "crus"and at "mid penis" the hemodynamic arterial parameters resulted normal. At the "crus" the EDV resulted significantly augmented (VOD index) in 96.6% (29); at "mid penis" augmented EDV was founded in 50% (15). CONCLUSIONS: These observational data would be able to confirm the utility of a routinary "double sampling" procedure, at the "crus" and at "md penis", during PDDU in order to better distinguish between VOD or AI or in any case to be useful to stimulate a future more precise standardization in execution of PDDU examination.

Impact of Thulium Laser Enucleation of the Prostate on Erectile, Ejaculatory and Urinary Functions.

OBJECTIVE: To test the impact of Thulium laser enucleation of the prostate (ThuLEP) on erectile and ejaculatory functions, on lower urinary tract symptoms and on quality of life (QoL). METHODS: From July 2013 to May 2015, we prospectively evaluated 177 patients with LUTS related to benign prostatic hyperplasia. All patients were assessed with the International Index of Erectile Function (IIEF-5), Male Sexual Health Questionnaire-Ejaculatory Disease (MSHQ-EjD), International Prostate Symptom Score (IPSS), QoL, PSA and uroflowmetry before and at 4 and 8 months after surgery. RESULTS: Erectile function did not show variation with IIEF-5 preoperative score 22.49 ± 1.8 and postoperative score 22.14 ± 3.1 (p = 0.195) and 22.18 ± 3.2 (p = 0.26) at 4 and 8 months after treatment. The ejaculatory function on the MSHQ-EjD test indicated the reduction of ejaculation, changing from 14.90 ± 6.88 to 5.51 ± 4.17 (p < 0.0001) and 5.38 ± 3.93 (p < 0.0001) at 4 and 8 months follow-up. IPSS score decreased from preoperative 21.12 ± 5.81 to 3.14 ± 3.16 (p < 0.0001) and 3.08 ± 3.12 (p < 0.0001) 4 and 8 months after surgery. PSA decreased from 4.50 ± 3.72 to 1.39 ± 1.04 (p < 0.0001) and 1.47 ± 1.14 ng/ml (p < 0.0001) at 4 and 8 months follow-up, while QoL score improved from 5.41 ± 0.69 to 0.57 ± 0.84 (p < 0.0001) and 0.51 ± 0.80 (p < 0.0001) at 4 and 8 months follow-up. CONCLUSIONS: ThuLEP does not affect erectile function and determines the resolution of LUTS with improvement of QoL. Loss of ejaculation did not impair the sexual intercourse activities of the patients.

Premature ejaculation. 3. Therapy.

Serotonergic drugs (SSRIs) are the most commonly used, but they are characterized by relapse some time after medication interruption as well as by sexual side effects. The efficacy of phosphodiesterase-5 inhibitors seems excellent, but the risk of tachyphylaxis has been reported. The former (fluoxetine, paroxetine, sertraline, clomipramine) should be used in young patients with hyper-orgasmic forms, while the latter (sildenafil, tadalafil, vardenafil) should be used in hypo-orgasmic forms, in old age or when PE is associated with erectile dysfunction. Topical anesthetics provide satisfactory results in premature ejaculation due to hypersensitivity of the glans, and physiotherapy of the pelvic floor muscles proves successful in cases associated with pelvic floor dysfunction. Therapeutic associations and psycho-sexual therapy techniques may improve results, particularly in the long term.
