RESUMO

OBJECTIVES: To evaluate the effects of testosterone-replacement therapy (TRT) on prostate health indicators in hypogonadal men, including rates of prostate cancer diagnoses, changes in prostate-specific antigen (PSA) levels and lower urinary tract symptoms (LUTS) over time. PATIENTS AND METHODS: The Registry of Hypogonadism in Men (RHYME) is a multi-national patient registry of treated and untreated, newly-diagnosed hypogonadal men (n = 999). Follow-up assessments were performed at 3-6, 12, 24, and 36 months. Baseline and follow-up data collection included medical history, physical examination, blood sampling, and patient questionnaires. Prostate biopsies underwent blinded independent adjudication for the presence and severity of prostate cancer; PSA and testosterone levels were measured via local and central laboratory assays; and LUTS severity was assessed via the International Prostate Symptom Score (IPSS). Incidence rates per 100 000 person-years were calculated. Longitudinal mixed models were used to assess effects of testosterone on PSA levels and IPSS. RESULTS: Of the 999 men with clinically diagnosed hypogonadism (HG), 750 (75%) initiated TRT, contributing 23 900 person-months of exposure. The mean testosterone levels increased from 8.3 to 15.4 nmol/L in treated men, compared to only a slight increase from 9.4 to 11.3 nmol/L in untreated men. In all, 55 biopsies were performed for suspected prostate cancer, and 12 non-cancer related biopsies were performed for other reasons. Overall, the proportion of positive biopsies was nearly identical in men on TRT (37.5%) compared to those not on TRT (37.0%) over the course of the study. There were no differences in PSA levels, total IPSS, or the IPSS obstructive sub-scale score by TRT status. Lower IPSS irritative sub-scale scores were reported in treated compared to untreated men. CONCLUSIONS: Results support prostate safety of TRT in newly diagnosed men with HG.

RESUMO

BACKGROUND: Genital dissatisfaction is an important reason for transmen to undergo genital gender-confirming surgery (GCS; phalloplasty or metoidioplasty). However, little is known about motives for choosing specific techniques, how transmen benefit postoperatively, and whether psychosexual outcomes improve. AIM: To evaluate motivations for and psychosexual outcomes after GCS. METHODS: A longitudinal study of 21 transmen at least 1 year after GCS was conducted. Participants were recruited through their surgeon. Data were collected when they applied for surgery and at least 1 year after surgery. OUTCOMES: Data collection included semistructured questionnaires on motivations for surgery, postoperative experiences, and standardized measures of psychological symptoms, body image, self-esteem, sexuality, and quality of life (pre- and postoperative). Information on surgical complications and corrections was retrieved from medical records. RESULTS: Most participants underwent phalloplasty with urethral lengthening using a radial forearm flap. Although problematic voiding symptoms were prevalent, many participants were satisfied with their penile function. The strongest motivations to pursue penile surgery were confirmation of one's identity (100%), enabling sexual intercourse (78%), and voiding while standing (74%). No significant differences between postoperative and reference values were observed for standardized measures. After surgery, transmen were more sexually active (masturbation and with a partner) and used their genitals more frequently during sex compared with before surgery (31-78%). CLINICAL IMPLICATIONS: The present study provides input for preoperative decision making: (i) main motives for surgery include identity confirmation, voiding, and sexuality, (ii) surgery can result in more sexual activity and genital involvement during sex, although some distress can remain, but (iii) complications and voiding symptoms are prevalent. STRENGTH AND LIMITATIONS: Study strengths include its longitudinal design and the novelty of the studied outcomes. The main limitations include the sample size and the nature of the assessment. CONCLUSION: Counseling and decision making for GCS in transmen should be a highly personalized and interdisciplinary practice. van de Grift TC, Pigot GLS, Boudhan S, et al.

RESUMO

BACKGROUND: The benefits and risks of long-term testosterone administration have been a topic of much scientific and regulatory interest in recent years. AIM: To assess long-term quality of life (QOL) and sexual function benefits of testosterone replacement therapy (TRT) prospectively in a diverse, multinational cohort of men with hypogonadism. METHODS: A multinational patient registry was used to assess long-term changes associated with TRT in middle-age and older men with hypogonadism. Comprehensive evaluations were conducted at 6, 12, 24, and 36 months after enrollment into the registry. OUTCOMES: QOL and sexual function were evaluated by validated measures, including the Aging Males' Symptom (AMS) Scale and the International Index of Erectile Function (IIEF). RESULTS: A total of 999 previously untreated men with hypogonadism were enrolled at 25 European centers, 750 of whom received TRT at at least one visit during the period of observation. Patients on TRT reported rapid and sustained improvements in QOL, with fewer sexual, psychological, and somatic symptoms. Modest improvements in QOL and sexual function, including erectile function, also were noted in RHYME patients not on TRT, although treated patients showed consistently greater benefit over time in all symptom domains compared with untreated patients. AMS total scores for patients on TRT were 32.8 (95% confidence interval = 31.3-34.4) compared with 36.6 (95% confidence interval = 34.8-38.5) for untreated patients (P < .001). Small but significant improvements in IIEF scores over time also were noted with TRT. Approximately 25% of treated and untreated men also used phosphodiesterase type 5 inhibitors, with notable differences in the frequency of phosphodiesterase type 5 inhibitor prescription use according to physician specialty and geographic site location. CLINICAL IMPLICATIONS: TRT-related benefits in QOL and sexual function are well maintained for up to 36 months after initiation of treatment. STRENGTHS AND LIMITATIONS: The major strengths are the large, diverse patient population being treated in multidisciplinary clinical settings. The major limitation is the frequency of switching from one formulation to another. CONCLUSION: Overall, we confirmed the broad and sustained benefits of TRT across major QOL dimensions, including sexual, somatic, and psychological health, which were sustained over 36 months in our treatment cohort.

RESUMO

BACKGROUND: There has been a longstanding question as to whether testosterone therapy could precipitate or worsen urinary symptoms in aging men. We investigated the effects of 1-year oral testosterone undecanoate (TU) therapy on urinary symptoms in aging, hypogonadal men. METHODS: A total of 322 men ≥50 years with symptomatic testosterone deficiency participated in a 1-year, randomized, multicenter, double-blind trial. Patients received placebo or oral TU 80 mg/day, 160 mg/day, or 240 mg/day. RESULTS AND LIMITATIONS: Compared with placebo, treatment with oral TU at doses of 80 mg/day and 160 mg/day resulted in no significant change in IPSS urinary symptoms or quality of life (QoL) scores. Treatment with oral TU 240 mg/day led to a statistically significant, but clinically insignificant, improvement in IPSS total score and a significant improvement in IPSS QoL score. None of the TU doses tested had a significant effect on PSA or PV. CONCLUSIONS: Long-term oral TU therapy had no deleterious effects on IPSS total score and did not change PV and PSA in aging, hypogonadal men. Oral TU therapy at a dose of 240 mg/day may even improve IPSS QoL score.

RESUMO

BACKGROUND: Botulinum toxin A (BoNT-A) is a new treatment modality in various causes of bladder dysfunction; like neurogenic detrusor overactivity and overactive bladder. The best technique of administrating BoNT-A in patients is unknown. A validated in vitro model could be used to investigate newer intravesical administration techniques of BoNT-A. In this study, we describe the development and validation of in vitro model to measure inhibitory effects of BoNT-A on bladder strip contractions. METHODS: Rat bladder strips were mounted in organ baths filled with Krebs' solution. The strips were stimulated chemically (80 mM potassium chloride, 1 µM carbachol) and electrically (Electrical Field Stimulation (EFS) 100 shocks, 50 V, 20 Hz, every 3 minutes). The viability of the strips was measured by carbachol stimulation at the beginning and at the end of the experiments. The strips were incubated in various concentrations of BoNT-A (0.03, 0.2, 0.3 nM). Controls were incubated in Krebs' solution only. The inhibition of strip contraction induced by EFS was measured. These measurements were statistically analyzed with a log-logistic model representing diffusion. RESULTS: All strips remained viable during the experiments. Inhibition of strip contraction was observed after incubation with 0.3 nM BoNT-A. The measurements fitted to a log-logistic model describing diffusion of BoNT-A in the bladder strip. The parameters of the log-logistic model representing diffusion were significant for 0.3 nM BoNT-A. Incubation with 0.2 nM BoNT-A showed insignificant results for 2 out of 3 runs. Incubation with 0.03 nM BoNT-A did not result in significant inhibition of strip contractions. CONCLUSIONS: An in vitro model was developed and validated in which the inhibitory effect of low concentrations of BoNT-A on bladder strip contractions can be measured.

RESUMO

PURPOSE: To obtain insight into demographical factors, histology and survival rates of females diagnosed with primary urethral cancer and to determine favourable treatment. METHODS: Data from 91 females with primary urethral carcinoma, age varying from 15 to 85 years, registered between 1989 and 2008 at the National Cancer Registry of the Netherlands were used for this study. Demographical factors, incidence rate, morphology and tumour stage according to TNM classification were analysed. Kaplan-Meier survival curves were constructed and stratified by stage, histological type and treatment modality. RESULTS: The overall crude annual incidence was 0.7 per million women with a peak incidence in the age group of 80-84 years. Analysis of the morphology showed urothelial cell carcinoma (UCC) in 45 %, squamous cell carcinoma (SCC) in 19 %, adenocarcinoma (AC) in 29 %, and unknown or undifferentiated carcinoma accounted for 6 %. Almost half of patients (46 %) had advanced disease at time of diagnosis and was mainly treated with surgery and/or radiotherapy. The 5-year survival rates of stage 0-II, stage III and stage IV were 67, 53 and 17 %, respectively. The 5-year survival rates of SCC, UCC and AC were 64, 61 and 31 %, respectively. CONCLUSIONS: Female primary urethral carcinoma is a rare condition, and the majority of patients were aged above 65 years. Almost half of patients have advanced disease upon diagnosis. TNM stage and histological type of disease are the most determining factors for survival. Extended surgery with or without radiotherapy seems to be the most favourable treatment. Awareness and early diagnosis are important to improve survival.

RESUMO

PURPOSE: Prostate cells are dependent on androgens for growth and proliferation. Androgen deprivation therapy is the recommended treatment for advanced/metastatic prostate cancer. Under this therapy, prostate cancer will inevitably progress to castration resistant prostate cancer (CRPC). Despite putative castration resistance, testosterone might still play a crucial role in the progression of CRPC. The goal of this study was to determine the role of testosterone in the formation of metastases of CRPC in both in vitro and in vivo settings. METHODS: In vitro, the effect of testosterone and the non-aromatizable androgen methyltrienolone on migration, invasion and proliferation of a castration-resistant prostate cancer rat cell line (Dunning R3327-MATLyLu) was assessed using a transwell assay and a sulforhodamine B assay and immunohistochemical detection of ki67. Androgen receptor status was determined using Western blot. In vivo, Copenhagen rats were divided in four groups (males, females, castrated males and females with testosterone suppletion) and inoculated with MATLyLu cells. Tumor size was assessed daily. RESULTS: Testosterone increased cell migration and invasion in a concentration-dependent manner in vitro. Testosterone did not affect in vitro cell proliferation. No difference was shown between the effect of testosterone and methyltrienolone. In vivo, in groups with higher levels of circulating testosterone, more rats had (micro)metastases compared with groups with low levels of testosterone. No effect was observed on primary tumor size/growth. CONCLUSIONS: Despite assumed castration resistance, progression of prostate cancer is still influenced by androgens. Therefore, continuous suppression of serum testosterone in patients who show disease progression during castration therapy is still warranted.

RESUMO

OBJECTIVE: We investigated the effects of oral testosterone undecanoate (TU) on bone mineral density (BMD), lean body mass (LBM) and body fat mass (BFM) in aging men with symptomatic testosterone deficiency (TD). METHODS: Three hundred twenty-two men ≥50 years with TD symptoms and calculated free testosterone <0.26 nmol/L participated in a multicenter, double-blind, placebo-controlled trial. Patients were randomized to placebo, oral TU 80 mg/d, oral TU 160 mg/d, or oral TU 240 mg/d, administered as divided doses with normal meals. BMD of the hip and lumbar spine were evaluated by dual energy X-ray absorptiometry (DEXA), and body composition (LBM and BFM) by whole body DEXA. RESULTS: Oral TU significantly increased BMD at Month 12 at the lumbar spine (240 mg/d), total hip (240 mg/d), and trochanter and intertrochanter (160 and 240 mg/d) compared with placebo. Oral TU significantly increased LBM at Months 6 and 12 for all oral TU groups compared with placebo. BFM significantly decreased at Month 6 (all oral TU groups) and Month 12 (160 mg/d) compared with placebo. The effects on BMD and body composition showed a clear dose response. CONCLUSIONS: Treatment with oral TU led to improvement in BMD, LBM and BFM in aging men with symptomatic TD.

RESUMO

PURPOSE: Androgen deprivation therapy by bilateral orchiectomy (surgical castration) or luteinizing hormone-releasing hormone agonist therapy (medical castration) is recommended for advanced or metastatic prostate cancer. Both methods aim at reducing serum testosterone concentrations to a castrate level which is currently defined as less than 50 ng/dl. The results of previous studies are based on testosterone immunoassays that have insufficient accuracy in the low range. In this study we reevaluated serum testosterone concentrations in men on androgen deprivation therapy using isotope dilution-liquid chromatography-tandem mass spectrometry, an accurate method of measuring testosterone in the castrate range. MATERIALS AND METHODS: Subjects underwent surgical castration (34) or received a luteinizing hormone-releasing hormone agonist (32). Serum samples were obtained more than 3 months after surgery or initiation of luteinizing hormone-releasing hormone agonist therapy. Testosterone levels were determined using isotope dilution-liquid chromatography-tandem mass spectrometry. Dihydroepiandrosterone sulfate, androstenedione, sex hormone-binding globulin and inhibin B levels were determined. RESULTS: All subjects had serum testosterone values less than 50 ng/dl and 97% had testosterone concentrations less than 20 ng/dl. Medically castrated men had significantly lower testosterone levels (median 4.0 ng/dl, range less than 2.9 to 20.2) than those surgically castrated (median 9.2 ng/dl, range less than 2.9 to 28.8, p <0.001). No difference was found in dehydroepiandrosterone sulfate, androstenedione and sex hormone-binding globulin levels between the groups, whereas inhibin B levels were significantly higher in the luteinizing hormone-releasing hormone agonist treated group. CONCLUSIONS: Using an accurate technique for testosterone measurement, subjects on luteinizing hormone-releasing hormone agonist therapy had significantly lower testosterone concentrations than men who underwent surgical castration. The clinical relevance of these findings remains to be determined.

RESUMO

Owing to inconsistencies and methodological differences, the present peer-reviewed literature lacks conclusive data on the intraprostatic levels of androgens, in particular dihydrotestosterone (DHT), in untreated benign prostatic hyperplasia (BPH) and prostate cancer. To date, no difference has been shown between DHT concentrations in normal prostatic tissue and BPH, and nor has a difference been shown in DHT concentrations between the histologically distinct regions of the prostate. Recent literature has also failed to show a consistent difference in androgen level between BPH and prostate cancer. The role of intraprostatic DHT in the pathogenesis of BPH and in the initiation and progression of prostate cancer thus remains to be established. Increased knowledge of the mechanisms of the androgenic steroid pathways in prostatic diseases, with a special focus on intraprostatic androgen levels may lead to more optimized and more personalized forms of treatment, and probably new therapeutic targets as well.

RESUMO

Androgen deprivation therapy (ADT) and 5-α-reductase (5AR) inhibition are used in the treatment of men with advanced or metastatic prostate cancer and benign prostatic hyperplasia (BPH), respectively. These drugs exert their effect by lowering androgen levels in the serum and allegedly, the prostate gland. It is, however, unknown whether (increased) intraprostatic androgen levels are associated with the pathogenesis of BPH and with the initiation and progression of prostate cancer. Also, it is unclear whether intraprostatic dihydrotestosterone (DHT) levels correlate with a response to initial hormonal therapy or with patient outcome. These uncertainties have resulted from the finding that serum testosterone levels do not necessarily reflect those in the prostate gland. Intraprostatic DHT levels of men being treated with 5AR inhibition, of those treated with ADT for hormone-naive prostate cancer, and of those with castration-resistant prostate cancer are all altered in an equivalent manner because of hormonal manipulation. Increased knowledge of the mechanisms of the androgenic steroid pathways in prostatic diseases, with a special focus on intraprostatic androgen levels, may lead to treatment that is tailored to the needs of the individual patient, and probably to new therapeutic targets as well.

RESUMO

INTRODUCTION: Addition of testosterone (T) may improve the action of phosphodiesterase type 5 inhibitors (PDE5-Is) in patients with erectile dysfunction not responding to PDE5-Is with low or low-normal T levels. AIMS: To confirm this add-on effect of T in men optimally treated with PDE5-Is and to specify the baseline T levels at which such an effect becomes significant. METHODS: A multicenter, multinational, double-blind, placebo-controlled study of 173 men, 45-80 years, nonresponders to treatment with different PDE5-Is, with baseline total T levels ≤ 4 ng/mL or bioavailable T ≤ 1 ng/mL. Men were first treated with tadalafil 10 mg once a day (OAD) for 4 weeks; if not successful, they were randomized in a double-blind, placebo-controlled design to receive placebo or a 1% hydroalcoholic T gel (50 mg/5 g gel), to be increased to 10 mg T if results were clinically unsatisfactory. Main Outcomes Measures. Mean change from baseline in the Erectile Function Domain Score of the International Index of Erectile Function and rate of successful intercourses (Sexual Encounter Profile 3 question). RESULTS: Erectile function progressively improved over a period of at least 12 weeks in both the placebo and T treatment groups. In the overall population with a mean baseline T level of 3.37 ± 1.48 ng/mL, no additional effect of T administration to men optimally treated with PDE5-Is was encountered. The differences between the T and placebo groups were significant for both criteria only in the men with baseline T ≤ 3 ng/mL. CONCLUSIONS: The maximal beneficial effects of OAD dosing with 10 mg tadalafil may occur only after as many as 12 weeks. Furthermore, addition of T to this PDE5-I regimen is beneficial, but only in hypogonadal men with baseline T levels ≤ 3 ng/mL.

RESUMO

INTRODUCTION: The Committee on "Clinical Evaluation and Scales in Sexual Medicine" of the third International Consultation in Sexual Medicine reviewed current practice and new developments in the field of physiological testing in male erectile dysfunction (ED). AIM: To provide an overview of current practice and new developments in the field of diagnostic testing in male ED. METHODS: The Pubmed literature was reviewed. RESULTS: Since the 1980s of the last century, a broad array of specialized physiological tests has been used for assessing ED. The notion that ED often is an (early) symptom of generalized cardiovascular disease and the introduction of oral pharmacological therapies that are effective irrespective of etiology has reduced the application of the "classical" tests to a minimum and has shifted the scope toward tests with demonstrated reliability in cardiovascular medicine. CONCLUSIONS: (i) The clinical utility of specialized tests in the evaluation of male ED is limited to a small minority of men; (ii) the scope of physiological testing has shifted toward tests with demonstrated reliability in cardiovascular medicine.

RESUMO

INTRODUCTION: The challenge in the field of sexual medicine is to develop evidence-based principles for clinical evaluation and create a uniform, widely accepted diagnostic and treatment approach for all sexual problems and dysfunctions, for both genders. AIM: To provide recommendations for the broad approach for assessing sexual problems in a medical practice setting; to develop an evidence-based diagnostic and treatment algorithm for men and women with sexual dysfunctions. METHODS: The PubMed literature was reviewed. Expert opinion was based on the grading of evidence-based medical literature and the Delphi consensus process. RESULTS: The Committee determined three principles for clinical evaluation and management: (i) adoption of a patient-centered framework, with emphasis on cultural competence in clinical practice; (ii) application of evidence-based medicine in diagnostic and treatment planning; (iii) use of a unified management approach in evaluating and treating sexual problems in both men and women. The International Consultation in Sexual Medicine-5 stepwise diagnostic and treatment algorithm was developed for that purpose. According to this algorithm, sexual, medical, and psychosocial history is mandatory, whereas physical examination and laboratory tests are highly recommended in most cases. Furthermore, the Brief Sexual Symptom Checklist (BSSC) for Men and BSSC for Women, and more recently the Sexual Complaints Screener (SCS) for Men and SCS for Women, were all endorsed for screening purposes. A classification system was also defined; clinically, sexual dysfunctions are categorized in three types according to their etiology (Type I: psychogenic; Type II: organic; Type III: mixed). Final recommendations on specialized diagnostic tests were based on level of evidence. CONCLUSIONS: A unified diagnostic and management strategy in sexual medicine, irrespective of condition and gender, would improve patients' sexual well-being. It would also lead to the development of academic curricula to provide practicing physicians across specialties with the needed skills to meet contemporary patients' needs in sexual medicine health-care delivery.

RESUMO

BACKGROUND: For transgender men choosing to undergo phalloplasty with urethral lengthening, there is a potential for hair growth in the neourethra. Depilation of the urethral donor site may reduce subsequent intraurethral hair growth. OBJECTIVES: To evaluate the effectiveness of preoperative laser depilation and assess the correlation between urethral hair density and voiding among transgender men undergoing phalloplasty with urethral lengthening. DESIGN, SETTING, AND PARTICIPANTS: This was a retrospective study of 25 transgender men undergoing phalloplasty with urethral lengthening between July 2010 and April 2015 at the VU University Medical Center in Amsterdam. INTERVENTION: Phalloplasty with urethral lengthening using skin with or without preoperative depilation. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Data on preoperative laser depilation treatments were obtained from the local laser center. Intraurethral images were captured via urethroscopy and used to rate hair density. Images of the contralateral forearm were used as a reference. Hair density was rated in terms of the number of hairs per view as zero, low (1-9), moderate (10-19), or high (≥20). Voiding was assessed using the International Prostate Symptom Score (IPSS) questionnaire, a 24-h voiding diary, and uroflowmetry. RESULTS AND LIMITATIONS: Twenty-five patients underwent urethroscopy. In the depilation group (n = 14) the hair reduction was significant and hair density was downgraded on average by 1.0 points (95% confidence interval [CI] 0.5-1.5). The mean number of laser treatment sessions was 6 (range 2-10). In the no-depilation group (n = 11), hair density did not significantly differ between the urethra and the contralateral arm (mean difference 0.18, 95% CI 0.5-0.9). The majority of the patients reported mild voiding complaints (median IPSS score 7, range 2-28) and had a normal functional bladder capacity and a nonobstructed urinary flow with low postvoid volumes. CONCLUSIONS: Laser epilation treatment reduces hair growth but does not eliminate hair. Voiding complaints do not seem to be related to hair density in the urethra. PATIENT SUMMARY: For skin donor sites used in penis construction for transgender men, the amount of hair growth is reduced by preoperative laser depilation, but hair is still present in the new urethra. Hair in the urethra does not cause urinary voiding complaints.

RESUMO

CONTEXT: Therapies initiated by urologists, medical as well as surgical, may cause adverse effects in different sexual domains. Sexual domains that are often affected are sexual interest, sexual activity, and erectile functioning. As many elderly men undergo these therapies, it is important to know the prevalence of sexual dysfunction (SD) in these domains and its impact in the healthy elderly male population. This may help healthcare providers counsel their patients properly on possible adverse effects. OBJECTIVE: To review the prevalence of sexual functioning and SD in the domains of sexual desire, sexual activity, and erectile dysfunction (ED) and its impact (bother and medical use), stratified by age. EVIDENCE ACQUISITION: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. Studies investigating the prevalence of SD, stratified by age, were eligible. Studies investigating bother due to ED, and studies evaluating medical use or use of medical professional healthcare providers in association with SD were eligible. EVIDENCE SYNTHESIS: A total of 76 articles were eligible for a full systematic review. Lack of sexual desire was reported to vary between 12% and 51.6% for men aged ≥60 yr, 20% and 65.9% for men aged ≥70 yr, and 40% and 82.4% for men aged ≥80 yr. The percentages of men bothered by ED were as follows: 14.3-70% for men aged ≥60 yr, 6.7-48% for men aged ≥70 yr, and 38% for men aged ≥80 yr. A substantial number of men (50.3-92%) find a normal sex life important as they age and remain sexually active. Only a minority of elderly men seek help from healthcare professionals or use medication for SD. CONCLUSIONS: The prevalence of SD in the healthy male population, reflected by a loss of sexual desire and sexual activity, increases only slightly with age. Bother due to ED is relatively low and there is an association with age. Still, a large number of men in the middle-aged and elderly groups regard sexuality as an important aspect of life. While considering a surgical or medical therapy that could have an impact on sexual functioning, sexually related outcomes should be set against current sexual functioning and a probable decline of sexual functioning due to ageing. PATIENT SUMMARY: While counselling elderly patients for sexual dysfunction when starting a treatment that could have an influence on sexual functioning, one should consider current sexual functioning and its importance for the individual.

RESUMO

BACKGROUND: This study was performed to assess spermatogenesis suppression and safety of a new combination of an etonogestrel (ENG) implant combined with testosterone undecanoate (TU) injections for male contraception. This is the first large placebo-controlled study for male hormonal contraception. DESIGN AND STUDY SUBJECTS: In this double-blind, multicenter study, we randomly assigned 354 healthy men to receive either a low- or high-release ENG implant sc combined with im TU injections (750 mg every 10 or 12 wk or 1000 mg every 12 wk) or placebo implant and injections. Treatment duration was 42 or 44 wk and posttreatment follow-up at least 24 wk. RESULTS: Overall, spermatogenesis was suppressed to 1 million/ml or less at wk 16 in 89% of men, with approximately 94% in two high-release ENG groups. Suppression was maintained up to the end of the treatment period in 91% of men. For all men who completed the treatment period, 3% never achieved 1 million/ml or less. Median recovery time to a sperm concentration above 20 million/ml was 15 wk (mean 17 wk, 95% confidence interval 16-18 wk). Treatment was well tolerated. As compared with the placebo group, more men in the active treatment groups reported adverse events such as weight gain, mood changes, acne, sweating, or libido change. For both spermatogenesis suppression and safety, differences were small between the active treatment groups. CONCLUSIONS: The combination of an ENG implant with TU injections is a well-tolerated male hormonal method, providing effective and reversible suppression of spermatogenesis. Although the results are good, there is still room for improvement, possibly by adjusting the dose regimen or changing the mode of application.

RESUMO

OBJECTIVE: To develop a contemporary, evidence-based definition of premature ejaculation (PE). METHODS: There are several definitions of PE; the most commonly quoted, the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders - 4th Edition - Text Revision, and other definitions of PE, are all authority-based rather than evidence-based, and have no support from controlled clinical and/or epidemiological studies. Thus in August 2007, the International Society for Sexual Medicine (ISSM) appointed several international experts in PE to an Ad Hoc Committee for the Definition of PE. The committee met in Amsterdam in October 2007 to evaluate the strengths and weaknesses of current definitions of PE, to critically assess the evidence in support of the constructs of ejaculatory latency, ejaculatory control, sexual satisfaction and personal/interpersonal distress, and to propose a new evidence-based definition of PE. RESULTS: The Committee unanimously agreed that the constructs which are necessary to define PE are rapidity of ejaculation, perceived self-efficacy, and control and negative personal consequences from PE. The Committee proposed that lifelong PE be defined as a male sexual dysfunction characterized by ejaculation which always or nearly always occurs before or within about one minute of vaginal penetration, and the inability to delay ejaculation on all or nearly all vaginal penetrations, and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy. This definition is limited to men with lifelong PE who engage in vaginal intercourse. The panel concluded that there are insufficient published objective data to propose an evidence-based definition of acquired PE. CONCLUSION: The ISSM definition of lifelong PE represents the first evidence-based definition of PE. This definition will hopefully lead to the development of new tools and patient-reported outcome measures for diagnosing and assessing the efficacy of treatment interventions, and encourage ongoing research into the true prevalence of this disorder, and the efficacy of new pharmacological and psychological treatments.

INTRODUCTION: The medical literature contains several definitions of premature ejaculation (PE). The most commonly quoted definition, the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition-Text Revision, and other definitions of PE are all authority based rather than evidence based, and have no support from controlled clinical and/or epidemiological studies. AIM: The aim of this article is to develop a contemporary, evidence-based definition of PE.

RESULTS: The committee unanimously agreed that the constructs that are necessary to define PE are rapidity of ejaculation, perceived self-efficacy and control, and negative personal consequences from PE. The committee proposed that lifelong PE be defined as ". . . a male sexual dysfunction characterized by ejaculation which always or nearly always occurs prior to or within about one minute of vaginal penetration, and the inability to delay ejaculation on all or nearly all vaginal penetrations, and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy." This definition is limited to men with lifelong PE who engage in vaginal intercourse. The panel concluded that there are insufficient published objective data to propose an evidence-based definition of acquired PE. CONCLUSION: The ISSM definition of lifelong PE represents the first evidence-based definition of PE. This definition will hopefully lead to the development of new tools and Patient Reported Outcome measures for diagnosing and assessing the efficacy of treatment interventions and encourage ongoing research into the true prevalence of this disorder and the efficacy of new pharmacological and psychological treatments.

RESUMO

Transurethral resection syndrome during transurethral resection of the prostate (TURP) results from excessive absorption of electrolyte-free irrigation fluids causing acute hypervolemia and hyponatremia. Neuraxial anesthesia is often recommended for TURP procedures because early signs of neurological deterioration can be detected. However, in patients requiring general anesthesia, other continuous and noninvasive measures are needed. Acute intravascular hypervolemia should be reflected by changes in hemodynamic values. Transesophageal Doppler ultrasonography of the aorta allows determination of stroke volume and other advanced hemodynamic variables related to intravascular volume status. We describe the first case of intraoperative detection of a TURP syndrome by noninvasive Doppler monitoring of hemodynamic variables during TURP.
