RESUMEN
OBJECTIVE: To describe the prevalence of Y-chromosome microdeletions in a multi-ethnic urban population in London, UK. To also determine predictive factors and a clinical threshold for genetic testing in men with Y chromosome microdeletions. PATIENTS AND METHODS: A retrospective cohort study of 1473 men that were referred to a tertiary Andrology centre with male factor infertility between July 2004 and December 2016. All had a genetic evaluation, hormonal profile and 2 abnormal semen analyses. Those with abnormal examination findings also had targeted imaging performed. RESULTS: The prevalence of microdeletions was 4% (n = 58) in this study. These microdeletions were partitioned into the following regions: Azoospermia factors (AZF); AZFc (75%), AZFb+c (13.8%), AZFb (6.9%), AZFa (1.7%), and partial AZFa (1.7%). A high follicle-stimulating hormone level (P < 0.001) and a low sperm concentration (P < 0.05) were both found to be significant predictors for the identification of a microdeletion. Testosterone level, luteinising hormone level and testicular volume did not predict the presence of a microdeletion. None of the men with an AZF microdeletion had a sperm concentration of >0.5 million/mL. Lowering the sperm concentration threshold to this level retained the high sensitivity (100%) and increased the specificity (31%). This would produce significant cost savings when compared to the European Academy of Andrology/European Molecular Genetics Quality Network and European Association of Urology guidelines. The surgical sperm retrieval (SSR) rate after microdissection testicular sperm extraction was 33.2% in men with AZFc microdeletion. CONCLUSIONS: The prevalence of Y-chromosome microdeletions in infertile men appears to vary between populations and countries. A low sperm concentration was a predictive factor (P < 0.05) for identifying microdeletions in infertile males. A threshold for genetic testing of 0.5 million/mL would increase the specificity and lower the relative cost without adversely affecting the sensitivity. The rate of SSR was lower than that previously described in the literature.

OBJECTIVES: To evaluate the efficacy and safety of collagenase clostridium histolyticum (CCH; Xiapex® , Xiaflex® ) in the treatment of Peyronie's disease (PD) using a new modified treatment protocol that aims at reducing the number of injections needed and reducing patient visits, thus reducing the duration and cost of treatment. PATIENTS AND METHODS: A prospective study of 53 patients with PD who had treatment with CCH at a single centre using a new modified protocol. The angle of curvature assessment after an intracavernosal injection of prostaglandin E1, the International Index of Erectile Function (IIEF) and Peyronie's Disease Questionnaire (PDQ) were completed at baseline and at week 12 (4 weeks after the last injection). The Global Assessment of Peyronie's disease (GAPD) questionnaire was completed at week 12. Under a penile block of 10 mL plain lignocaine 1%, a total of three intralesional injections of CCH (0.9 mg) were given at 4-weekly intervals using a new modified injection technique. In between injections patients used a combination of home modelling, stretching and a vacuum device on a daily basis to mechanically stretch the plaque. Investigator modelling was not performed. RESULTS: The mean (range) penile curvature at baseline was 54 (30-90)°. Of the 53 patients in the study, 51 patients (96.2%) had an improvement in the angel of curvature by a mean (range) of 17.36 (0-40)° or 31.4 (0-57)% from baseline after three CCH injections. The final mean (range) curvature was 36.9 (12-75)° (P < 0.001). There was an improvement in each of the IIEF questionnaire domains, all three PDQ domains and the GAPD. CCH was well tolerated by all patients with only mild and transient local adverse events. CONCLUSION: The new shortened protocol using CCH treatment is safe, effective, and cost efficient. The results of using only three CCH injections according to this modified protocol are comparable to those of the clinical trials that used eight CCH injections.

OBJECTIVE: To assess the prevalence of obstructive sleep apnoea (OSA) in men presenting with erectile dysfunction (ED) at a single centre. PATIENTS AND METHODS: All men attending a specialised andrology outpatient department with a new diagnosis of ED were included in this prospective study. All patients completed three questionnaires: the International Index of Erectile Function (IIEF) and two sleep questionnaires [the Obstructive Sleep Apnoea Screening questionnaire and the Insomnia Severity Index (ISI)]. Their ED management was subsequently undertaken in accordance with local and European guidelines. An OSA diagnosis was made based on a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire and those patients were referred for specialist management. RESULTS: Between February and September 2016, 129 patients with ED completed the study questionnaires. In all, 71 patients (55%) had a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire, indicating a need for specialist sleep referral. Men who scored ≥3 on the Obstructive Sleep Apnoea Screening questionnaire were significantly older (61.4 vs 46.5 years; P < 0.001) and had a significantly higher body mass index (29.4 vs 26.7 kg/m2 ; P < 0.001) when compared to the control group (OSA score of <3). The sleep apnoea group (OSA score of ≥3) had significantly worse IIEF-ED scores (6.2 vs 9.1; P = 0.018) and ISI scores (7.9 vs 5.5; P = 0.061). CONCLUSION: Men presenting to the andrology clinic with ED are at significant risk of having undiagnosed sleep disorders. This has serious adverse health consequences, as well as being associated with potential dangers at work and travel. The patient compliance was high with 78% completing all three questionnaires. It is feasible to screen this population for sleep disturbance and this should be part of the ED assessment.

BACKGROUND: Collagenase Clostridium histolyticum (CCH) is indicated for the treatment of penile curvature in adult men with Peyronie's disease (PD) with palpable plaque and curvature deformity of at least 30° at the start of therapy. AIM: To evaluate the efficacy and safety of CCH plus vacuum-pump therapy with and without penile modeling for the management of PD. METHODS: Adult men with PD and penile curvature of at least 30° were randomly assigned to receive CCH 0.58 mg plus vacuum therapy alone (n = 15) or with penile plaque modeling (n = 15). Patients received no more than four treatment cycles (cycle = â¼6-week duration), each consisting of two intralesional injections of CCH administered 24 to 72 hours apart. Vacuum therapy was applied twice daily from 14 days after the second injection of each cycle until the following cycle. Modeling was performed 24 to 72 hours after the second injection of each cycle. OUTCOMES: The primary end point was change in penile curvature from baseline to week 36; additional end points included changes in Peyronie's Disease Questionnaire (PDQ) domain scores, composite response (≥20% decrease in penile curvature and decrease in PDQ bother score ≥ 1 point), and global response (small but important, moderate, or much improvement in the Global Assessment of PD). RESULTS: At week 36, improvement in penile curvature from baseline was similar in the two groups (mean change from baseline = -23.7° [SD = 10.9] for CCH + vacuum + modeling and -23.3° [SD = 7.2] for CCH + vacuum; between-group difference = -0.3°, 95% CI = -7.3 to 6.6). Improvements in most PDQ domains, including bother, were observed from baseline to week 36 in the two groups. Most patients were composite (66.7% and 84.6% with CCH + vacuum + modeling and CCH + vacuum, respectively) and global (86.7% and 92.3%, respectively) responders. The most common adverse events were penile contusion, penile swelling, and penile pain. CLINICAL IMPLICATIONS: Vacuum-pump therapy administered alone or in combination with modeling after CCH treatment could improve PD symptoms. STRENGTHS AND LIMITATIONS: This was a pilot study with a small sample and limited follow-up duration. CONCLUSION: CCH and vacuum-pump therapy (alone or combined with modeling) could be an appropriate consideration for men with PD and warrants further investigation. Ralph DJ, Abdel Raheem A, Liu G.

INTRODUCTION: Although genital injuries in civilian centers are rare, the scenario is completely different in the battlefield. If the penile distal stump is not adequate for primary reimplantation or it cannot be found, then delayed penile reconstruction needs to be considered. AIM: To report a single-center experience with total phallic reconstruction using radial artery based forearm free flap (RAFFF) after penile traumatic loss. METHODS: We retrospectively reviewed the clinical records of 10 patients who underwent total phallic reconstruction with the use of the RAFFF from September 2001 through August 2015 after traumatic amputation of the penis. MAIN OUTCOME MEASURES: Patients' baseline features, surgical outcomes, complications, and satisfaction are reported. RESULTS: The average age at the time of penile reconstruction was 36 years (range = 27-52 years). The causes of penile loss were self-amputation owing to an acute schizophrenic episode (n = 2), road traffic accident (n = 3), blast injury (n = 3), donkey bite (n = 1), and Fournier gangrene (n = 1). The average time from the trauma to reconstruction with the RAFFF was 7 years (range = 2-15 years). The urethral stump was adequate for primary anastomosis, with phallic neourethra construction in six patients. The remaining patients had complete avulsion of the penis and were voiding though a perineal urethrostomy. In consequence, they required a two-stage urethroplasty. An acute arterial thrombosis of the microsurgical anastomosis occurred in two patients and was managed successfully with immediate exploration. A neourethra stricture and fistula occurred in one patient, which needed revision. All patients who underwent complete urethral reconstruction could void and ejaculate from the tip of the phallus. After a median follow-up of 51 months (range = 1-114 months), all patients were satisfied with the size, cosmetic appearance, and sensation of the phallus. Six patients underwent inflatable penile prosthesis implantation and could engage in penetrative sex. However, revision surgery was needed in three patients (infection, n = 2; mechanical failure, n = 1). CONCLUSION: Despite the high incidence of postoperative complications and the possible need for multiple operations, in expert hands and in large-volume centers, penile reconstruction with the RAFFF after traumatic loss of the penis yields excellent results and allows patients to regain sexual and urinary functions.

PURPOSE: The current management of ischemic priapism that is refractory to conventional medical therapy is a form of shunt procedure that diverts blood away from the corpus cavernosum. We assessed the outcome of the T-shunt and intracavernous tunneling for the management of ischemic priapism. MATERIALS AND METHODS: During a 36-month period 45 patients presented with prolonged ischemic priapism. Patients were divided into subgroups according to the duration of priapism. All patients had an unsuccessful primary treatment, and underwent a T-shunt and intracavernous tunneling with cavernous muscle biopsies. All patients completed an IIEF-5 (International Index of Erectile Function-5) questionnaire preoperatively and 6 months postoperatively. RESULTS: Resolution of the priapism using a T-shunt and snake maneuver occurred in all patients with a priapism duration of less than 24 hours and in only 30% of those with priapism lasting more than 48 hours. After a 6-month median followup the IIEF-5 score was significantly reduced from a mean of 24 (range 23 to 25) preoperatively to 7.7 (range 5 to 24), which was related to the duration of the priapism (p <0.0005). All patients with priapism for more than 48 hours had necrotic cavernous smooth muscle on biopsy and had severe erectile dysfunction requiring the insertion of a penile prosthesis. Those patients with moderate and mild erectile dysfunction were treated with phosphodiesterase type 5 inhibitors. CONCLUSIONS: The success of the T-shunt with snake tunneling is dependent on the duration of priapism. When it is less than 24 hours the results are favorable, although erectile dysfunction is still present in 50% of patients. In those with a priapism duration greater than 48 hours the technique usually fails to resolve the priapism and all patients end up with erectile dysfunction due to smooth muscle necrosis.

OBJECTIVE: To compare the long-term results of early and delayed insertion of a penile prosthesis (PP) in men with refractory ischaemic priapism (IP). PATIENTS AND METHODS: Early insertion of a PP was carried out in 68 men with IP within a median of 7 days from the onset of priapism, while 27 had delayed insertion after a median of 5 months. The results for sexual ability, satisfaction and subjective penile shortening were assessed by questioning at follow-up visits. RESULTS: In the early group, a malleable and an inflatable PP were implanted in 64 and four patients, respectively. After a median follow-up of 17 months, six patients needed revision surgery due to infection and curvature. Patient's satisfaction rate and ability to have sexual intercourse was 96%. In the delayed group, a malleable PP was inserted in 12 patients and an inflatable in the remaining 15. In all, 80% of the patients required a second corporotomy and downsized cylinders due to dense fibrosis. After a median follow-up of 21 months,seven patients required revision surgery due to infection,erosion and mechanical failure. In all, 25 patients were able to engage in sexual intercourse but the satisfaction rate was only 60% mainly due to significant penile shortening. CONCLUSIONS: Early PP implantation should be the preferred option inpatients with IP, as the procedure is technically easier, has less complication rates and allows greater preservation of penile length.

This study aimed at assessing a new line of treatment for lifelong premature ejaculation which is botulinum-A toxin injection into the bulbospongiosus muscle. Sixty patients with lifelong premature ejaculation were independently randomized into 2 groups; group I, 100 U botulinum-A toxin at 10 U/ml saline was injected with ultrasound guidance into the bulbospongiosus muscle and group II which was injected with similar volume of saline. The primary outcome was to compare both groups for changes in the Premature Ejaculation Profile (PEP), Intravaginal Ejaculatory Latency Time (IELT) and partner's satisfaction at 1, 3 and 6 months after intervention. The second outcome was to compare the adverse events in both groups. Fifty-seven patients completed the study. In group I, the mean PEP increased significantly at 1- (P = 0.02) and 3- months (P = 0.04) with insignificant increase at 6-month (P = 0.6) of follow-up. Also, no significant changes had been noted in IELT or partner's satisfaction scores throughout the study duration (P > 0.05). In group II, no significant changes had been noted in the PEP, IELT and partner's satisfaction scores throughout the study duration (P > 0.05). There were insignificant differences in the changes in the mean PEP (P = 0.7, 0.6 and 0.4), IELT (P = 0.6,0.6 and 0.5) and partner's satisfaction scores (P = 0.5,0.7 and 0.3) in comparison to the baseline values at 1-, 3- and 6- months, respectively between both groups. Adverse events were observed in only 3 patients (5.3%). In group I, mild erectile dysfunction and post micturition dribbling were reported in one patient each. Where in group II, one patient reported bleeding per urethra (P = 0.5). To conclude, injection of botulinum-A toxin into bulbospongiosus seems to be safe but failed to prove clinical efficacy for treatment of lifelong premature ejaculation when compared to placebo.
RESUMEN
UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The management of patients with non-obstructive azoospermia (NOA) involves testicular sperm extraction (TESE or microdissection TESE) combined with intracytoplasmic sperm injection (ICSI). Sperm retrieval is successful in up to 50% of men with NOA; however, there is no single clinical finding or investigation that can accurately predict a positive outcome. Several studies have concluded that testicular biopsy is the best predictor of a successful TESE. The present study shows that the strongest predictor of the success of TESE is when tubules with mature spermatozoa (Johnsen score ≥8) are found in the histopathology specimen, irrespective of the overall state of spermatogenesis. The findings suggest that a lower limit threshold value of 2% of tubules with spermatogenesis in the histopathology specimen will result in a positive sperm retrieval. However, it is not practical to perform a diagnostic biopsy before TESE because this would mean that patients undergo two surgeries, which adds to the cost and increases the complications. The diagnostic biopsy is best coupled with an initial TESE before starting the ICSI cycle. Based on the findings of the histopathology specimen, patients may be then offered a repeat TESE if more sperm is needed on the day of ovum pick-up and ICSI. Also, if the initial TESE was negative, the biopsy result will help in the decision to offer a repeat TESE. This regimen is more cost-effective because the ICSI cycle will be started only if adequate sperm is retrieved. OBJECTIVE: To assess whether testicular histopathology can predict the outcome of testicular sperm extraction (TESE) in men with non-obstructive azoospermia (NOA) and therefore the role of preoperative diagnostic testis biopsy. PATIENTS AND METHODS: The study comprised a retrospective analysis of 388 patients with azoospermia who were referred from 2005 to 2010. Information collected included a clinical history and an examination including age and testicular size, serum follicle-stimulating hormone, two semen analyses and testicular histology collected at the time of surgical sperm retrieval (TESE or microdissection TESE). RESULTS: In total, 388 patients with a mean (range) age of 37 (18-66) years were included in the present study. Based on the history, clinical and laboratory findings, 112 patients had obstructive azoospermia and 276 patients had NOA. All patients in the obstructed group had a positive sperm retrieval. The sperm retrieval rate for the NOA group was 50%. An analysis of the results showed that the best predictor of a positive sperm retrieval was when tubules with mature spermatozoa were seen at biopsy, irrespective of the overall state of spermatogenesis (P < 0.001). CONCLUSIONS: The presence of tubules with spermatazoa on biospy is the best predictor of a positive surgical sperm retrieval in patients with NOA. The diagnostic biopsy is best coupled with an initial TESE before starting the intracytoplasmic sperm injection (ICSI) cycle. Based on the findings of the histopathology specimen, patients may be offered a repeat TESE if more sperm is needed on the day of ovum pick-up and ICSI, or a redo TESE if the initial TESE was negative.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: The management of patients with non-obstructive azoospermia (NOA) and some cases of obstructive azoospermia involves testicular sperm extraction (TESE or micro-dissection TESE) combined with intracytoplasmic sperm injection (ICSI). Several studies have investigated the effect of the male age, the cause of azoospermia, testicular histopathology, the type of sperm used, and the use of pentoxyphilline, on the ICSI cycle outcome in men with azoospermia. The present study showed that none of these factors influenced the ICSI outcome in men with azoospermia, thus once sperm is found in an azoospermic male, no other male factor seems to influence the ICSI outcome. To our knowledge this is the first study to comment on the outcome of ICSI in men with NOA based on testicular histopathology. OBJECTIVES: To access the effect of: male age, the cause of azoospermia (obstructive azoospermia vs non-obstructive azoospermia [NOA]), testicular histopathology, the type of sperm used (fresh vs frozen-thawed), and the use of pentoxyphilline on the intracytoplasmic sperm injection (ICSI) cycle outcome in men with azoospermia. To our knowledge this is the first study to comment on the outcome of ICSI in men with NOA based on testicular histopathology. PATIENTS AND METHODS: A retrospective analysis of 137 testicular sperm extraction-ICSI cycles performed between 2001-2010, involving 103 men with azoospermia, with 26 couples having repeat cycles. RESULTS: Analysis of the results did not show any statistically significant differences in the fertilization, embryo cleavage, clinical pregnancy, live birth and miscarriage rates in relation to the male age, cuase of azoospermia, testicular histopathology, type of sperm used and the use of pentoxyphilline. CONCLUSION: Once sperm is found in a man with azoospermia, no other male factor seems to influence the ICSI outcome.

OBJECTIVE: To evaluate sexual functions of patients with erectile dysfunction (ED) and their female partners. METHODS: A total of 90 consecutive ED patients who received different ED therapies and their partners and 90 consecutive controls and their partners were divided into four groups. All participants were evaluated by the 15-item international index of erectile function and the Arabic version of female sexual function index (Ar-FSFI). RESULTS: All ED patients who received sildenafil demonstrated significant improvements of their erectile function compared to baseline. Their partners did not demonstrate improvements in frequency of pain during vaginal penetration (3.86 ± 0.58, 3.93 ± 0.45, p = 0.477), confidence of becoming aroused (3.86 ± 0.58, 3.93 ± 0.45, p 0.477), frequency of satisfaction with arousal (3.07 ± 0.37, 3.03 ± 0.49, p 0.712), and maintenance of lubrication (4.37 ± 0.49, 4.23 ± 0.73, p 0.354). All ED patients who received quadmix demonstrated significant improvements of their erectile function compared to baseline. Their partners did not demonstrate improvements in desire level (2.6 ± 0.67, 2.63 ± 0.85, p = 0.869) and lubrication maintenance (3.53 ± 0.82, 3.47 ± 0.82, p = 0.423). Finally, All ED patients who underwent semi rigid penile implant demonstrated significant improvements of their erectile function compared to baseline. Their female partners demonstrated significant improvements in all items of FSFI-19 compared to baseline except the frequency of pain during vaginal penetration (3.86 ± 0.58, 3.93 ± 0.45, p = 0.477), confidence of becoming aroused (3.86 ± 0.58, 3.93 ± 0.45, p = 0.477), frequency of satisfaction with arousal (3.07 ± 0.37, 3.03 ± 0.49, p = 0.712), and maintenance of lubrication (4.37 ± 0.49, 4.23 ± 0.73, p = 0.354). CONCLUSIONS: Sexual functions of ED males significantly improved after ED therapies. Nevertheless, some sexual functions of their partners were not positively impacted.

BACKGROUND: There has been recent interest in the use of botulinum neurotoxin (BoNT) in the field of Andrology, whereby it has been investigated in the treatment of penile retraction and premature ejaculation. OBJECTIVES: To evaluate the safety and efficacy of intracavernosal BoNT-A injection in the treatment of patients with erectile dysfunction (ED) refractory to oral phosphodiesterase inhibitors (PDE5Is). PATIENTS AND METHODS: A double-blind randomized placebo-controlled prospective comparative study conducted at one center and involved 70 patients with ED refractory to PDE5Is. At baseline, the following data were collected: erection hardness score (EHS), peak systolic velocity (PSV), end diastolic velocity (EDV), sexual health inventory for men (SHIM), and the sexual encounter profile 2&3 (SEP-2&3) questionnaires. Treatment group (n = 35) received a single ICI of 100 units of BoNT-A in 2 ml of saline and control group (n = 35) received a single ICI of 2 ml of saline. EHS, PSV, and EDV were assessed at 2 weeks post treatment. SHIM, SEP-2, SEP-3, and global assessment questionnaire (GAQ-Q1&Q2) were completed at 2-, 6-, and 12-weeks post treatment. RESULTS: Two weeks post treatment, the treatment group showed a statistically significant improvement in the mean EHS, PSV, EDV, and GAQ-Q1 positive responders (p < 0.001) compared to the control group. At 6- and 12-weeks post treatment, the treatment group showed a statistically significant improvement in the SHIM scores, SEP-2, and GAQ-Q1&Q2 positive responders compared to the control group. At 6 weeks, where there was a 5-point improvement in the mean SHIM score of the treatment group (10±5.9 from 5.4±1.7 at baseline) versus no improvement in the placebo group, 18 patients in the treatment group (53%) were able to have an erection hard enough for vaginal penetration versus only one patient in the control group. CONCLUSION: BoNT-A is safe and effective as a potential treatment for ED refractory to PDE5I therapy.

The past decade has seen a significant development in penile reconstruction techniques, and the management of penile fracture has progressively shifted from a conservative approach to early surgical repair. The radial artery-based free flap phalloplasty now represents the gold-standard procedure for total phallic reconstruction both in men and in female-to-male transsexuals.

Klinefelter Syndrome (KS) is characterized by the presence of an extra X chromosome. It was first diagnosed in 1942 in a group of azoospermic men. KS is the most common chromosomal abnormality encountered in infertile men and accounts for more than 10% of the causes of azoospermia. Men who are azoospermic may still father children via testicular sperm extraction followed by intracytoplasmic sperm injection (ICSI). This review article summarizes the success rates of the available techniques for surgical sperm retrieval (SSR) in KS including conventional testicular sperm extraction (cTESE) and micro testicular sperm extraction (mTESE), as well as the risks of these procedures for future fertility. The evidence indicates that the SSR rate is as successful in non-mosaic men with KS as those with normal karyotypes, with retrieval rates of up to 55% reported. The influence of different factors that affect the chances of a successful outcome are discussed. In particular, the impact of aneuploidy rate, physical characteristics, co-morbidities, reproductive endocrine balance and the use of different hormone management therapies are highlighted. Evidence is presented to suggest that the single most significant determinant for successful SSR is the age of the patient. The success of SSR is also influenced by surgical technique and operative time, as well as the skills of the surgeon and embryology team. Rescue mTESE may be used successfully following failed TESE in KS patients in combination with hormone stimulation.
RESUMEN
Objective To differentiate the in vitro fertilization (IVF) outcomes between the two procedures, intracytoplasmic morphologically selected sperm injection (IMSI) and intracytoplasmic sperm injection (ICSI) in terms of relation to chemical pregnancy percentage, clinical pregnancy, live birth, miscarriage, and fertilization rates, respectively. Patients and methods This Open Prospective clinical trial was conducted during the period between Jan 2016 and Dec 2017 at one IVF unit. A total of 446 ICSI cycles and 79 IMSI cycles were conducted. Females were divided into four subgroups according to age. Results The study involved 525 couples (446 first trial ICSI cycles) and (79 first trial IMSI cycles). ICSI was statistically better than the IMSI in relation to the chemical pregnancy, clinical pregnancy (CPR), live birth (LBR), and fertilization rates, respectively (p < 0.05). However, there were no statistically significant differences between the ICSI and IMSI in relation to the miscarriage rate. There were statistically significant differences favoring ICSI in all subgroups except 35-37, in relation to chemical pregnancy; and in the 38-40 and >40 subgroups in relation to CPR. There were no statistically significant differences in these subgroups regarding the live birth, miscarriage, or fertilization rates. Conclusions This study showed that IMSI is not superior to conventional ICSI at the first attempt. Based on the findings in this study, we would not advise couples to choose IMSI at their first treatment attempt.

Gynecomastia is defined as a palpable enlargement of the male breast, secondary to an increase in the glandular and stromal breast tissue. Gynecomastia is encountered in up to 80% of Klinefelter syndrome cases. The pathophysiology involves testosterone/estrogen imbalance. This review article will further explore the pathophysiology of gynecomastia along with the different lines of management.
RESUMEN
INTRODUCTION: Sexual dysfunctions (SDs) have been frequently reported among male partners of infertile couples due to psychogenic, relational and/or organic issues related with the inability to conceive. Likewise, male infertility (MI) could be a consequence of sexual dysfunctions. AIM: To review the evidence on the prevalence and treatment of male SDs in men of infertile couples and provide clinical recommendations on behalf of the European Society of Sexual Medicine (ESSM). METHODS: The MEDLINE database was searched in September 2019 for randomized clinical trials (RCTs), meta-analyses and open-label prospective or retrospective studies investigating the presence of erectile dysfunction (ED) and/or ejaculatory dysfunctions (EjDs) and/or low sexual desire (LSD) in conjunction with infertility. MAIN OUTCOME MEASURE: The panel provided statements on: (i) Prevalence and association between SDs and MI; (ii) Treatment of male SDs in men of infertile couples. RESULTS: ED has been reported in 9% to 62% of male partners of infertile couples, with severe impairment observed in only 1% to 3% of ED cases. Moreover, worse semen parameters have been associated with greater ED severity. Phosphodiesterase type 5 inhibitors (PDE5is) can be safely used to treat ED among patients seeking fatherhood. Male partners of infertile couples are at higher risk of premature ejaculation (PE). Retrograde ejaculation (RE) and anejaculation are a cause of MI and can be managed with electroejaculation (EEJ) or penile vibratory stimulation (PVS) or, alternatively, with oral treatments, however the latter with limited documented success. Low sexual desire has been reported by one third of men of infertile couples. CONCLUSION: ED could significantly affect male partners of infertile couple; PDE5is should be suggested to ensure an effective and satisfactory sexual relationship of the couple. Anejaculation and RE should be considered as a possible cause of MI and treated accordingly. Low sexual desire is frequently reported among men of infertile couple and could be a symptom of other systemic conditions or psychological distress. Capogrosso P, Jensen CFS, Rastrelli G, et al.

RESUMEN
Objective: To examine the effectiveness of preoperative urethral sterilisation with chlorhexidine gel in rendering the urethra as sterile as the skin of the genital area, with the skin sterilised as per the International Society for Sexual Medicine guidelines for penile prosthesis implantation. Patients and methods: A total of 111 male patients undergoing sterile andrological surgical procedures were divided into a control group (N = 61) and a chlorhexidine gel group (N = 50). Patients in the chlorhexidine group received urethral instillation with 6 mL of chlorhexidine preoperatively and on table. Patients from both groups received on-table skin preparation using povidone iodine and chlorhexidine povidone iodine. At the end of surgery, swabs were obtained from urethra and the penile skin. Skin and urethral swabs were compared for bacterial colonisation by culture and sensitivity. Results: Of the 111 patients, 16 had urethral colonisation and 10 had skin contamination, and they were all in the control group. The most common organism detected in both the urethral and skin samples was coagulase-negative Staphylococcus aureus. Urethral colonisation was significantly greater in the control group compared to the chlorhexidine group, at 16/61 vs 0/50 (P = 0.001). Similarly, skin colonisation was significantly greater in the control group compared to the chlorhexidine group, at 10/61 vs 0/50, (P = 0.002). Conclusion: Chlorhexidine gel is a powerful sterilising agent that will render the urethra sterile.
RESUMEN
OBJECTIVE: to assess the efficacy of vacuum therapy in mechanically straightening the penile curvature of Peyronie's disease (PD). PATIENTS AND METHODS: Modelling of the tunica albuginea has been shown to be possible during penile implant surgery and this principle has been applied as an alternative conservative therapy. In all, 31 patients with PD (mean duration 9.9 months; mean age 51 years, range 24-71) completed the study. Over a 12-week period, the patients used a vacuum device (Osbon ErecAid, MediPlus, High Wycombe, UK) for 10 min twice daily. The assessment at study entry and at completion after 12 weeks included the International Index of Erectile Function questionnaire, a perceived pain intensity score, stretched penile length measurement and the angle of penile deformity after an intracavernous injection with prostaglandin E1. RESULTS: there was a clinically and statistically significant improvement in penile length, angle of curvature and pain after 12 weeks of using the vacuum pump. Of the 31 patients, 21 had a reduction in the angle of curvature by 5-25 degrees, three had worsening of the curvature and there was no change in the remaining seven. The curvature was corrected surgically in 15 patients while the remaining 16 (51%) were satisfied with the outcome. CONCLUSION: vacuum therapy can improve or stabilize the curvature of PD, is safe to use in all stages of the disease, and might reduce the number of patients going on to surgery.
