"Management of andrological disorders from childhood and adolescence to transition age: guidelines from the Italian Society of Andrology and Sexual Medicine (SIAMS) in collaboration with the Italian Society for Pediatric Endocrinology and Diabetology (SIEDP)-Part-1".

PURPOSE: Andrological pathologies in the adulthood are often the results of conditions that originate during childhood and adolescence and sometimes even during gestation and neonatal period. Unfortunately, the reports in the literature concerning pediatric andrological diseases are scares and mainly concerning single issues. Furthermore, no shared position statement are so far available. METHODS: The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving the Italian Society of Pediatric Endocrinology and Diabetology (SIEDP) to provide an updated guideline on the diagnosis and management of andrological disorders from childhood and adolescence to transition age. Derived recommendations were based on the grading of recommendations, assessment, development, and evaluation (GRADE) system. RESULTS: A literature search of articles in English for the term "varicoceles", "gynecomastia", "fertility preservation", "macroorchidism", "precocious puberty" and "pubertal delay" has been performed. Three major aspects for each considered disorder were assessed including diagnosis, clinical management, and treatment. Recommendations and suggestions have been provided for each of the mentioned andrological disorders. CONCLUSIONS: These are the first guidelines based on a multidisciplinary approach that involves important societies related to the field of andrological medicine from pediatric to transition and adult ages. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving andrological and general health of the transitional age.

Surgical and minimally invasive treatment of ischaemic and non-ischaemic priapism: a systematic review by the EAU Sexual and Reproductive Health Guidelines panel.

Surgical treatments for ischemic priapism (IP) include shunts or penile implants. Non-ischemic priapism (NIP) is usually the result of penile/perineal trauma causing an arterial fistula and embolisation may be required. We conducted a systematic review on behalf of the EAU Sexual and Reproductive health Guidelines panel to analyse the available evidence on efficacy and safety of surgical modalities for IP and NIP. Outcomes were priapism resolution, sexual function and adverse events following surgery. Overall, 63 studies (n = 923) met inclusion criteria up to September 2021. For IP (n = 702), surgery comprised distal (n = 274), proximal shunts (n = 209) and penile prostheses (n = 194). Resolution occurred in 18.7-100% for distal, 5.7-100% for proximal shunts and 100% for penile prostheses. Potency rate was 20-100% for distal, 11.1-77.2% for proximal shunts, and 26.3-100% for penile prostheses, respectively. Patient satisfaction was 60-100% following penile prostheses implantation. Complications were 0-42.5% for shunts and 0-13.6% for IPP. For NIP (n = 221), embolisation success was 85.7-100% and potency 80-100%. The majority of studies were retrospective cohort studies. Risk of bias was high. Overall, surgical shunts have acceptable success rates in IP. Proximal/venous shunts should be abandoned due to morbidity/ED rates. In IP > 48 h, best outcomes are seen with penile prostheses implantation. Embolisation is the mainstay technique for NIP with high resolution rates and adequate erectile function.

First baseline data of the Klinefelter ItaliaN Group (KING) cohort: clinical features of adult with Klinefelter syndrome in Italy.

BACKGROUND: Klinefelter syndrome (KS) is frustratingly under-diagnosed. KS have a broad spectrum of clinical features, making it difficult to identify.  OBJECTIVE: We describe KS clinical presentation in a large Italian cohort. DESIGN: This is the first observational cohort study within a national network, the Klinefelter ItaliaN Group (KING). Primary outcomes were to describe the basic clinical features and the actual phenotype of KS in Italy. Secondary outcomes were to determine age at diagnosis and geographical distribution. METHODS: We performed a basic phenotyping and evaluation of the hormonal values of 609 adult KS patients. RESULTS: Mean age at diagnosis was 37.4 ± 13.4 years. The overall mean testicular size was 3 ml, and 2.5 ml in both testes in untreated KS group. BMI was 26.6 ± 5.8 kg/m2, and 25.5% of KS had metabolic syndrome (MetS). LH and FSH were increased, and mean total testosterone were 350 ± 9.1 ng/dl. A descriptive analysis showed that 329 KS patients were evaluated in Northern Italy, 76 in Central and 204 in Southern Italy. Analysis of variance demonstrated significant statistical differences (p < 0001) between the age at diagnosis of the three geographical groups. Compared with the expected number among male patients matched for age in Italy, only 16% of KS patients received a diagnosis. CONCLUSIONS: These data are the results of the only national database available that collects the clinical and hormonal data of the KS patients, currently referred at the KING centers. In Italy the typical KS patient is overweight, with small testes, and elevated LH and FSH. Only 25.5% of them are diagnosed with MetS. Early detection and timely treatment are mandatory.

Erectile dysfunction and premature ejaculation: a continuum movens supporting couple sexual dysfunction.

PURPOSE: The specific underlying mechanisms supporting the association between erectile dysfunction (ED) and premature ejaculation (PE) are still not completely clarified. To summarize and discuss all available data supporting the relationship between PE and ED. METHODS: A comprehensive narrative review was performed. In addition, to better clarify the specific factors underlining ED and PE, a meta-analytic approach of the selected evidence was also performed. In particular, the meta-analytic method was selected in order to minimize possible sources of bias derived from a personal interpretation of the data. RESULTS: Current data confirm the close association between ED and PE and the bidirectional nature of their relationship. In particular, PE was associated with a fourfold increased risk of ED independently of the definition used. In addition, the risk increased in older patients and in those with lower education, and it was associated with higher anxiety and depressive symptoms. Conversely, ED-related PE was characterized by lower associations with organic parameters such as diabetes mellitus, arterial hypertension, dyslipidemia and with smoking habit. Finally, when ED was defined according to the International Index of Erectile Function questionnaire, the presence of a stable relationship increased the risk. CONCLUSIONS: ED and PE should be considered in a dimensional prospective way considering the possibility that both clinical entities can overlap and influence each. Correctly recognizing the underlying factors and sexual complaint can help the clinician in deciding the more appropriate diagnostic and therapeutic work-up.

SIGIS-SIAMS-SIE position statement of gender affirming hormonal treatment in transgender and non-binary people.

PURPOSE: Gender Incongruence (GI) is a marked and persistent incongruence between an individual's experienced and the assigned gender at birth. In the recent years, there has been a considerable evolution and change in attitude as regards to gender nonconforming people. METHODS: According to the Italian Society of Gender, Identity and Health (SIGIS), the Italian Society of Andrology and Sexual Medicine (SIAMS) and the Italian Society of Endocrinology (SIE) rules, a team of experts on the topic has been nominated by a SIGIS-SIAMS-SIE Guideline Board on the basis of their recognized clinical and research expertise in the field, and coordinated by a senior author, has prepared this Position statement. Later on, the present manuscript has been submitted to the Journal of Endocrinological Investigation for the normal process of international peer reviewing after a first internal revision process made by the SIGIS-SIAMS-SIE Guideline Board. RESULTS: In the present document by the SIGIS-SIAMS-SIE group, we propose experts opinions concerning the psychological functioning, gender affirming hormonal treatment, safety concerns, emerging issues in transgender healthcare (sexual health, fertility issues, elderly trans people), and an Italian law overview aimed to improve gender non-conforming people care. CONCLUSION: In this Position statement, we propose experts opinions concerning the psychological functioning of transgender people, the gender-affirming hormonal treatment (full/partial masculinization in assigned female at birth trans people, full/partial feminization and de-masculinization in assigned male at birth trans people), the emerging issues in transgender health care aimed to improve patient care. We have also included an overview of Italian law about gender affirming surgery and registry rectification.

Biochemical predictors of structural hypothalamus-pituitary abnormalities detected by magnetic resonance imaging in men with secondary hypogonadism.

PURPOSE: Organic conditions underlying secondary hypogonadism (SH) may be ascertained by magnetic resonance imaging (MRI) of the hypothalamic-pituitary region that could not be systematically proposed to each patient. Based upon limited evidence, the Endocrine Society (ES) guidelines suggest total testosterone (T) < 5.2 nmol/L to identify patients eligible for MRI. The study aims to identify markers and their best threshold value predicting pathological MRI findings in men with SH. METHODS: A consecutive series of 609 men seeking medical care for sexual dysfunction and with SH (total T < 10.5 nmol/L and LH ≤ 9.4 U/L) was retrospectively evaluated. An independent cohort of 50 men with SH was used as validation sample. 126 men in the exploratory sample and the whole validation sample underwent MRI. RESULTS: In the exploratory sample, patients with pathological MRI findings (n = 46) had significantly lower total T, luteinizing hormone (LH), follicle stimulating hormone (FSH) and prostate specific antigen (PSA) than men with normal MRI (n = 80). Receiver Operating Characteristics analysis showed that total T, LH, FSH and PSA are accurate in identifying men with pathologic MRI (accuracy: 0.62-0.68, all p < 0.05). The Youden index was used to detect the value with the best performance, corresponding to total T 6.1 nmol/L, LH 1.9 U/L, FSH 4.2 U/L and PSA 0.58 ng/mL. In the validation cohort, only total T ≤ 6.1 nmol/L and LH ≤ 1.9 U/L were confirmed as significant predictors of pathologic MRI. CONCLUSION: In men with SH, total T ≤ 6.1 nmol/L or LH ≤ 1.9 U/L should arise the suspect of hypothalamus/pituitary structural abnormalities, deserving MRI evaluation.

Sexual function in men undergoing androgen deprivation therapy.

Androgen deprivation therapy (ADT) has a deleterious effect on sexual functions and general well-being in men. Despite this evidence, however, patient and couple knowledge about ADT side effects as well as their management is poor. Similar considerations can be made for physician endorsement of management strategies. In this paper, we summarize and critically discuss available evidence regarding the possible associations between ADT and sexual dysfunction as well as the best therapeutical options. Preclinical data show that ADT is associated with penile contractility impairment as well as lower response to phosphodiesterase type 5 inhibitors (PDE5i). Available data indicate that ADT resulted in a five to sixfold increased risk of reduced libido and in a threefold increased risk of ED confirming the main role of testosterone in regulating sexual desire. Despite this evidence, sexuality remains an important aspect of health and well-being for men and their partner. The best therapeutical options depend on patient and couple desires and needs. When nonpenetrative erections are still possible, nonpenetrative activities should be encouraged to maintain sexual intimacy. A combined and personal educational program including the collaboration of different professional figures (including general physicians, oncologists, andrologists, sexologists, and psychologists) trained in sexual medicine is advisable in order to provide the best support to subjects undergoing ADT.

People smoke for nicotine, but lose sexual and reproductive health for tar: a narrative review on the effect of cigarette smoking on male sexuality and reproduction.

PURPOSE: To systematically review the impact of smoking habits on cardiovascular (CV) as well as on male sexual and reproductive function and to provide updated evidence on the role of electronic cigarettes (e-Cig) on the same topics. METHODS: A comprehensive Medline, Embase, and Cochrane search was performed including the following words: smoking, CV system, CV risk, erectile dysfunction (ED), and male fertility. Publications from January 1, 1969 up to February 29, 2020 were included. RESULTS: Smoking has a tremendous negative impact on CV mortality and morbidity. Current smoking behavior is also negatively associated with erectile dysfunction (ED) and impaired sperm parameters. E-Cig can release significantly lower concentrations of harmful substances when compared to regular combustible cigarettes. Whether or not the latter can result in positive CV, sexual, and fertility outcomes is still under study. Preliminary studies showed that exposure to e-Cig leads to lower vascular damage when compared to the traditional cigarette use. However, data on the long-term effects of e-Cig are lacking. Similarly, preliminary data, obtained in animal models, have suggested a milder effect of e-Cig on erectile function and sperm parameters. CONCLUSION: Available evidence showed that e-Cig are much less dangerous when compared to the traditional tobacco use. However, it should be recognized that the risk related to e-Cig is still higher when compared to that observed in non-smoking patients. Hence, e-Cig should be considered as a potential tool, in the logic of harm reduction, to reduce the CV, sexual and fertility risk in patients refractory to the fundamental, healthy choice to definitively quit smoking.

Results and predictors of outcome of endoscopic endonasal surgery in Cushing's disease: 20-year experience of an Italian referral Pituitary Center.

PURPOSE: To assess outcomes and predictors of early and long-term remission in patients with Cushing's disease (CD) due to ACTH-secreting adenomas treated via endoscopic endonasal approach (EEA). METHODS: This is a retrospective study. Consecutive patients operated for CD from 1998 to 2017 in an Italian referral Pituitary Center were enrolled. Clinical, radiological, and histological data at enrollment and follow-up were collected. RESULTS: 151 patients (107 F) were included; 88.7% were naïve for treatment, 11.3% had been treated surgically and 11.2% medically. At pre-operative magnetic resonance imaging (MRI), 35 had a macroadenoma and 80 a microadenoma, while tumor was undetectable in 36 patients. Mean age at surgery was 41.1 ± 16.6 years. Diagnosis was confirmed histologically in 82.4% of the cases. Patients with disease persistence underwent second surgery and/or medical and/or radiation therapy. Mean follow-up was 92.3 ± 12.0 (range 12-237.4) and median 88.2 months. Remission rate was 88.1% after the first surgery and 90.7% at last follow-up. One patient died of pituitary carcinoma. Post-surgical cortisol drop (p = 0.004), tumor detection at MRI (p = 0.03) and size < 1 cm (p = 0.045) increased the chance of disease remission; cavernous sinus invasion was a negative predictor of outcome (p = 0.002). Twenty-seven patients developed diabetes insipidus and 18 hypopituitarism. Surgery repetition increased the risk of hypopituitarism (p = 0.03), but not of other complications, which included epistaxis (N = 2), cerebrospinal fluid leakage (1), pneumonia (3), myocardial infarction (1), and pulmonary embolisms (2). CONCLUSIONS: Selective adenomectomy via EEA performed by experienced surgeons, supported by a multidisciplinary dedicated team, allows long-term remission in the vast majority of CD patients with low complication rate.

EAA clinical practice guidelines-gynecomastia evaluation and management.

BACKGROUND: Gynecomastia (GM) is a benign proliferation of the glandular tissue of the breast in men. It is a frequent condition with a reported prevalence of 32-65%, depending on the age and the criteria used for definition. GM of infancy and puberty are common, benign conditions resolving spontaneously in the majority of cases. GM of adulthood is more prevalent among the elderly and proper investigation may reveal an underlying pathology in 45-50% of cases. OBJECTIVES: The aim was to provide clinical practice guidelines for the evaluation and management of GM. MATERIALS AND METHODS: A literature search of articles in English for the term 'gynecomastia' was conducted. Evidence-based recommendations were developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. RESULTS: A set of five statements and fifteen clinical recommendations was formulated. CONCLUSIONS: The purpose of GM assessment should be the detection of underlying pathological conditions, reversible causes (administration/abuse of aggravating substances), and the discrimination from other breast lumps, particularly breast cancer. Assessment should comprise a thorough medical history and physical examination of the breast and genitalia (including testicular ultrasound). A set of laboratory investigations may integrate the evaluation: testosterone (T), estradiol (E2), sex hormone-binding globulin (SHBG), luteinizing hormone (LH), follicular stimulating hormone (FSH), thyroid stimulating hormone (TSH), prolactin, human chorionic gonadotropin (hCG), alpha-fetal protein (AFP), liver and renal function tests. Breast imaging may be used whenever the clinical examination is equivocal. In suspicious lesions, core needle biopsy should be sought directly instead. Watchful waiting is recommended after treatment of underlying pathology or discontinuation of substances associated with GM. T treatment should be offered to men with proven T deficiency. The use of selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs) and non-aromatizable androgens is not justified in general. Surgical treatment is the therapy of choice for patients with long-lasting GM. SUMMARY OF STATEMENTS (S) AND RECOMMENDATIONS (R): S1. Gynecomastia (GM) is a benign proliferation of glandular tissue of the breast in males. S2. GM of infancy is a common condition that usually resolves spontaneously, typically within the first year of life. S3. GM of puberty is a common condition, affecting approximately 50% of mid-pubertal boys; in more than 90% of cases, it resolves spontaneously within 24 months. S4. The prevalence of GM in adulthood increases with increasing age; proper investigation may reveal an underlying pathology in approximately 45-50% of the cases. S5. Male breast cancer is rare; GM should not be considered a premalignant condition. The following recommendations are divided into 'strong', denoted by the number 1 and associated with the terminology 'we recommend', and 'weak' denoted by the number 2 and associated with the phrase 'we suggest'. The grading of the quality of evidence is denoted as follows: ⊕○○○ for very low-quality evidence; ⊕⊕○○ for low quality; ⊕⊕⊕○ for moderate quality; and ⊕⊕⊕⊕ for high quality. R1. The presence of an underlying pathology should be considered in GM of adulthood. We recommend that the identification of an apparent reason for GM in adulthood, including the use of medication known to be associated with GM, should not preclude a detailed investigation (1 ⊕⊕⊕○). R2. We suggest that the initial screening to rule out lipomastia, obvious breast cancer, or testicular cancer might be performed by a general practitioner or another non-specialist (2 ⊕○○○). R3. We recommend that in those cases where a thorough diagnostic workup is warranted, it should be performed by a specialist (1 ⊕○○○). R4. We recommend that the medical history should include information on the onset and duration of GM, sexual development and function, and administration or abuse of substances associated with GM (1 ⊕⊕⊕○). R5. We recommend that the physical examination should detect signs of under-virilization or systemic disease (1 ⊕⊕⊕⊕). R6. We recommend that breast examination should confirm the presence of palpable glandular tissue to discriminate GM from lipomastia (pseudo-gynecomastia) and rule out the suspicion of malignant breast tumor (1 ⊕⊕⊕⊕). R7. We recommend that the physical examination should include the examination of the genitalia to rule out the presence of a palpable testicular tumor and to detect testicular atrophy (1 ⊕⊕⊕⊕). R8. We recommend that genitalia examination is aided by a testicular ultrasound, as the detection of a testicular tumor by palpation has low sensitivity (1 ⊕⊕○○). R9. We suggest that a set of evaluations may include T, E2 , SHBG, LH, FSH, TSH, prolactin, hCG, AFP, and liver and renal function tests (2 ⊕⊕○○). R10. We suggest that breast imaging may offer assistance, where the clinical examination is equivocal (2 ⊕⊕○○). R11. We suggest that, if the clinical picture is suspicious for a malignant lesion, core needle biopsy should be performed (2 ⊕⊕○○). R12. We recommend watchful waiting after treatment of underlying pathology or discontinuation of the administration/abuse of substances associated with GM (1 ⊕⊕○○). R13. We recommend that T treatment should be offered only to men with proven testosterone deficiency (1 ⊕⊕⊕○). R14. We do not recommend the use of selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs), or non-aromatizable androgens in the treatment of GM in general (1 ⊕⊕○○). R15. We suggest surgical treatment only for patients with long-lasting GM, which does not regress spontaneously or following medical therapy. The extent and type of surgery depend on the size of breast enlargement, and the amount of adipose tissue (2 ⊕⊕○○).

The prevalence of midline prostatic cysts and the relationship between cyst size and semen parameters among infertile and fertile men.

STUDY QUESTION: When is the investigation and treatment of midline prostatic cysts (MPC) of clinical value in the work-up of males of infertile couples? SUMMARY ANSWER: With a prevalence of 10.2% in infertile men, MPC should be investigated according to a seminal algorithm detecting a MPC volume >0.117 ml, which may impair semen parameters, and could be treated to improve sperm count and achieve natural pregnancy. WHAT IS KNOWN ALREADY: MPC are frequent and are considered a correctable cause of male infertility. However, they have been poorly investigated in an infertility setting. In addition, no study has investigated clinical and ultrasound (US) characteristics of men with MPC. STUDY DESIGN, SIZE, DURATION: A cross-sectional analysis was carried out of 693 consecutive subjects consulting for couple infertility from September 2012 to March 2017. As a control group, 103 age-matched healthy, fertile men were studied. Furthermore, a longitudinal evaluation of 11 infertile men undergoing trans-rectal ultrasonically-guided cyst aspiration (TRUCA), semen analyses 1 and 3 months after TRUCA and a follow-up 1 year after TRUCA to assess natural pregnancy were performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: All subjects underwent, in our outpatient clinic, clinical, hormonal, scrotal and transrectal US evaluation and semen analysis within the same day. Of 693 males of infertile couples, 648 (37.1 ± 7.9 years, mean+SD) without genetic abnormalities were studied, along with 103 fertile men (36.6 ± 5.0 years). Eleven infertile men underwent TRUCA and were followed-up as reported above. MAIN RESULTS AND THE ROLE OF CHANCE: A MPC was present in 66/648 (10.2%) males of infertile couples and in 6/103 (5.8%) fertile men. MPC occurrence and volume were higher in patients with severe oligo- or azoospermia than in fertile men (all P < 0.05). Infertile men with a MPC showed a lower seminal volume and sperm count and a higher prevalence of azoospermia than the rest of the infertile sample or fertile men, and a higher frequency of US signs suggestive of ejaculatory duct obstruction. MPC volume was negatively associated with total sperm count (r = -0.452, P < 0.0001). In fertile men, the highest MPC volume was 0.117 ml, suggesting it as a biological threshold not compromising semen quality. In infertile men, using receiver operating characteristic curve analyses, a MPC volume >0.117 ml identified subjects with severe oligo- or azoospermia with an overall accuracy of ~75% (both P < 0.005). Eleven men with infertility, semen abnormalities and large MPC (>0.250 ml) underwent TRUCA, which led to sperm count improvement in all patients 1 month after surgery. Three months after TRUCA a lower sperm count and a higher MPC volume than 2 months before were observed (P < 0.005 and P < 0.05, respectively), although improved when compared to baseline. After TRUCA a natural pregnancy occurred in four couples. Finally, we propose an algorithm, based on semen parameters, useful in identifying a MPC in males of infertile couples. LIMITATIONS, REASONS FOR CAUTION: Although in line with the sample size of previous studies (n = 7-20), the number of infertile men with MPC evaluated longitudinally after treatment is limited (n = 11). In addition, although a MPC volume >0.117 ml can negatively affect the sperm count, only MPC > 0.250 ml have been treated in this study. WIDER IMPLICATIONS OF THE FINDINGS: First, the algorithm proposed is easy to use and useful for selecting patients who can benefit from a prostate US in the infertility work-up. Second, a MPC volume ≤0.117 ml may not impair semen quality, while a larger volume can lead to severe oligo- or azoospermia and could be treated. Third, TRUCA is effective, and simpler and less invasive than other surgical techniques for MPC treatment. Finally, since the MPC can increase in size and sperm count decrease over time after TRUCA, semen cryopreservation should be considered 1 month after TRUCA.

Testosterone deficiency in non-cancer opioid-treated patients.

PURPOSE: The use of opioids in patients with chronic non-cancer pain is common and can be associated with opioid-induced androgen deficiency (OPIAD) in men. This review aims to evaluate the current literature regarding the prevalence, clinical consequence and management of OPIAD. METHODS: A database search was performed in Medline, Embase and Cochrane using terms such as "analgesics", "opioids" and "testosterone". Relevant literature from January 1969 to March 2018 was evaluated. RESULTS: The prevalence of patients with OPIAD ranges from 19 to 86%, depending on the criteria for diagnosis of hypogonadism. The opioid-induced suppression of gonadotropin-releasing and luteinizing hormones represents the main important pathogenetic mechanisms. OPIAD has significant negative clinical consequences on sexual function, mood, bone density and body composition. In addition, OPIAD can also impair pain control leading to hyperalgesia, which can contribute to sexual dysfunction and mood impairment. CONCLUSIONS: OPIAD is a common adverse effect of opioid treatment and contributes to sexual dysfunction, impairs pain relief and reduces overall quality of life. The evaluation of serum testosterone levels should be considered in male chronic opioid users and the decision to initiate testosterone treatment should be based on the clinical profile of individuals, in consultation with the patient.

The safety of available treatments of male hypogonadism in organic and functional hypogonadism.

INTRODUCTION: In the case of primary male hypogonadism (HG), only testosterone (T) replacement therapy (TRT) is possible whereas when the problem is secondary to a pituitary or hypothalamus alteration both T production and fertility can be, theoretically, restored. We here systematically reviewed and discussed the advantages and limits of medications formally approved for the treatment of HG. AREAS COVERED: Data derived from available meta-analyses of placebo controlled randomized trials (RCTs) were considered and analyzed. Gonadotropins are well-toleratedand their use is mainly limited by higher costs and a more cumbersome treatment schedule than TRT. Available RCTs on TRT suggest that cardiovascular (CV) and venous thromboembolism risk is not a major issue and that prostate safety is guaranteed. The risk of increased hematocrit is mainly limited to the use of short terminjectable preparations. EXPERT OPINION: In the last few years the concept of 'organic' irreversible HG and 'functional' or age- and comorbidity-related HG has been introduced. This definition is not evidence-based. The majority of RCTs enrolled patients with 'functional' HG. Considering the significant improvement in body composition, glucose metabolism and sexual activity, TRT should not be limited to 'organic' HG, but also offered for 'functional'.

Erectile function recovery in men treated with phosphodiesterase type 5 inhibitor administration after bilateral nerve-sparing radical prostatectomy: a systematic review of placebo-controlled randomized trials with trial sequential analysis.

The impact of phosphodiesterase type 5 inhibitor (PDE5I) treatment modality (on-demand vs. daily), PDE5I half-life and time from surgery to PDE5I prescription on the achievement of drug-assisted erectile function (EF) recovery is uncertain. We systematically reviewed published randomized clinical trials (RCTs). We performed meta-analyses of data on 2317 men treated with PDE5Is after nerve-sparing radical prostatectomy (NSRP). A PubMed and SCOPUS search was performed for trials published from 1 January 1969 to 30 June 2016. PDE5Is are effective in achieving drug-assisted recovery of erectile function (EF). From a statistical standpoint, these studies were subjected to Trial Sequential Analysis to determine whether the pooled data were adequately powered to verify the study outcomes. On-demand treatment with PDE5Is was significantly better than daily treatment in recovering drug-assisted EF. This effect was maintained even when the drugs were stratified according with half-life. Although not based on head-to-head trials, Avanafil used on-demand was the most effective PDE5I in recovering drug-assisted EF. Whereas tadalafil was equally effective when used both on-demand and daily, vardenafil significantly improved drug-assisted EF recovery only when used on-demand. The start of PDE5I treatment six months or more after surgery compared to treatment started earlier did not negatively affect the rate of drug-assisted EF recovery or the possibility to have successful intercourse based on the Sexual Encounter Profile question-3 (SEP-3). Current trials do not support the hypothesis that PDE5I use recovers drug-unassisted EF, although chronic low-dose tadalafil administration may help to preserve erectile tissue integrity. Potential shortcomings in the trials design may partially explain these disappointing results and several questions concerning the recovery of drug-unassisted EF remain unanswered. Thus, there is a need for well-designed new RCTs requiring changes in the timing of PDE5I administration as well as in the dose and the treatment duration.

Sexual dysfunction in subjects treated with inhibitors of 5α-reductase for benign prostatic hyperplasia: a comprehensive review and meta-analysis.

Despite their efficacy in the treatment of benign prostatic hyperplasia, the popularity of inhibitors of 5α-reductase (5ARIs) is limited by their association with adverse sexual side effects. The aim of this study was to review and meta-analyze currently available randomized clinical trials evaluating the rate of sexual side effects in men treated with 5ARIs. An extensive Medline Embase and Cochrane search was performed including the following words: 'finasteride', 'dutasteride', 'benign prostatic hyperplasia'. Only placebo-controlled randomized clinical trials evaluating the effect of 5ARI in subjects with benign prostatic hyperplasia were considered. Of 383 retrieved articles, 17 were included in this study. Randomized clinical trials enrolled 24,463 in the active and 22,270 patients in the placebo arms, respectively, with a mean follow-up of 99 weeks and mean age of 64.0 years. No difference was observed between trials using finasteride or dutasteride as the active arm considering age, trial duration, prostate volume or International Prostatic Symptoms Score at enrollment. Overall, 5ARIs determined an increased risk of hypoactive sexual desire [OR = 1.54 (1.29; 1.82); p < 0.0001] and erectile dysfunction [OR = 1.47 (1.29; 1.68); p < 0.0001]. No difference between finasteride and dutasteride regarding the risk of hypoactive sexual desire and erectile dysfunction was observed. Meta-regression analysis showed that the risk of hypoactive sexual desire and erectile dysfunction was higher in subjects with lower Qmax at enrollment and decreased as a function of trial follow-up. Conversely, no effect of age, low urinary tract symptom or prostate volume at enrollment as well as Qmax at end-point was observed. In conclusion, present data show that the use of 5ARI significantly increases the risk of erectile dysfunction and hypoactive sexual desire in subjects with benign prostatic hyperplasia. Patients should be adequately informed before 5ARIs are prescribed.

Field-assisted paper spray mass spectrometry for therapeutic drug monitoring: 1. the case of imatinib in plasma.

The field-assisted paper spray (FAPS) - mass spectrometric method has been employed to quantify the imatinib (IMT) plasma levels in treated patients. The quantitative measurements have been performed on the collisionally generated fragment at m/z 394 of the protonated molecules of IMT and deuterated IMT (d3 -IMT), used as internal standard. The FAPS-tandem mass spectrometry (MS/MS) method exhibits some limitations, because of the high number of operative parameters that need to be carefully controlled. For this aim, papers of different geometry, thickness, and porosity were tested. To obtain a more focalized and intense electrical field, a stainless steel needle was mounted axially and placed at 4 kV voltage. The variability observed in the measurements was ascribed either to the inter-individual variability (e.g. the concomitant presence of other compounds such as proteins, lipids, drugs and/or salts in the plasma of different patients) or to the uncontrollable variables in the instrumental set-up (e.g. sample deposition, changes in paper spray conditions). Furthermore, the manual sample deposition and solvent dripping strongly affects the measure reproducibility. Despite this, it is interesting to observe that, once applied in blind on 24 real plasma samples, FAPS-MS/MS led to results analogous to those obtained by the well-consolidated liquid chromatography-MS/MS, even if the mean coefficient of variation % (CV%) values of 20.4% and 2.6% were observed for the two methods, respectively. In conclusion, despite CV values are relatively high, it is worth noting that the FAPS-MS/MS method is much more straightforward, rapid and economical than the liquid chromatography-MS/MS one, and it appears therefore very promising for applications where a high precision is not always a required task, as e.g. in some cases of therapeutic drug monitoring.

Current smoking is associated with lower seminal vesicles and ejaculate volume, despite higher testosterone levels, in male subjects of infertile couples.

STUDY QUESTION: What is the impact of smoking behaviour on seminal, hormonal and male genital tract ultrasound parameters in subjects seeking medical care for couple infertility? STUDY ANSWER: In males of infertile couples, current smokers (CS), when compared with non-smokers, show lower ejaculate and ultrasound-derived seminal vesicles (SV) volume, despite higher testosterone levels. WHAT IS KNOWN ALREADY: Data on the effects of smoking on male fertility are conflicting. A correlation between smoking and reduced semen parameters has been reported, however, with a high heterogeneity among studies. An association between smoking behaviour and higher testosterone levels in men has been described in several, but not all, the previous studies. No study has systematically evaluated the impact of smoking on the male genital tract ultrasound characteristics. STUDY DESIGN, SIZE AND DURATION: Retrospective cross-sectional analysis of a consecutive series of 426 subjects seeking medical care for couple infertility from January 2010 to July 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS: From the entire cohort, 394 men (age 36.0 ± 8.0 years) free of genetic abnormalities were selected. All subjects underwent a complete andrological and physical examination, biochemical and hormonal assessment, scrotal and transrectal colour-Doppler ultrasound and semen analysis (including seminal interleukin-8 levels, sIL-8) within the same day. MAIN RESULTS AND THE ROLE OF CHANCE: Among the patients evaluated, 229 were never smokers (NS), 56 past smokers (PS) and 109 CS. When CS were compared with the rest of the sample (non-smokers, NS + PS), in a multivariate model (analysis of covariance, ANCOVA) adjusted for age, lifestyle (including alcohol, cannabis and physical activity), BMI and sex hormone-binding globulin, significantly higher androgen (total testosterone, P = 0.001; calculated free testosterone, P < 0.005) and lower FSH (P < 0.05) levels were observed in CS. However, when total testosterone was also included in the multivariate model as a further covariate, the difference in FSH levels was not confirmed. In a similar model, a lower ejaculate volume (P < 0.01) and a higher prevalence of normal sperm morphology (P < 0.02) were also detected in CS in comparison with the rest of the sample. However, when total testosterone was also included in the multivariate model as a further covariate, only the difference in ejaculate volume between CS and non-smokers was confirmed (-0.61 ± 0.23 ml, P < 0.01). Finally, CS showed lower total SV volume, before and after ejaculation, even after adjusting for confounders (P = 0.02 and <0.01, respectively). Similar results were observed when the reported number of cigarettes smoked or the number of pack-years was considered separately. LIMITATIONS, REASONS FOR CAUTION: The present results are derived from patients consulting an Andrology Clinic for couple infertility, who could have different characteristics from the general male population or males consulting general practitioners for reasons other than couple infertility. In addition, we did not have a true control group composed of age-matched, apparently healthy, fertile men, and therefore true normative data of sonographic parameters cannot be inferred. Due to the cross-sectional nature of our study, neither a causality hypothesis nor mechanistic models can be drawn. Finally, this is a retrospective study, and further prospective studies are required. WIDER IMPLICATIONS OF THE FINDINGS: We report an apparent paradox in CS: lower SV volume despite higher testosterone levels. Our data suggest that smoking may negatively affect SV volume in an independent manner, as the difference between CS and non-smokers retained significance after adjusting for confounders including testosterone. This is the first study reporting such ultrasound evidence. How this new smoking-related alteration, along with low semen volume, impacts male fertility needs to be addressed by further studies. STUDY FUNDING/COMPETING INTERESTS: No funding was received for the study. None of the authors have any conflict of interest to declare.

Testosterone Replacement Therapy and Cardiovascular Risk: A Review.

Recent reports in the scientific and lay press have suggested that testosterone (T) replacement therapy (TRT) is likely to increase cardiovascular (CV) risk. In a final report released in 2015, the Food and Drug Administration (FDA) cautioned that prescribing T products is approved only for men who have low T levels due to primary or secondary hypogonadism resulting from problems within the testis, pituitary, or hypothalamus (e.g., genetic problems or damage from surgery, chemotherapy, or infection). In this report, the FDA emphasized that the benefits and safety of T medications have not been established for the treatment of low T levels due to aging, even if a man's symptoms seem to be related to low T. In this paper, we reviewed the available evidence on the association between TRT and CV risk. In particular, data from randomized controlled studies and information derived from observational and pharmacoepidemiological investigations were scrutinized. The data meta-analyzed here do not support any causal role between TRT and adverse CV events. This is especially true when hypogonadism is properly diagnosed and replacement therapy is correctly performed. Elevated hematocrit represents the most common adverse event related to TRT. Hence, it is important to monitor hematocrit at regular intervals in T-treated subjects in order to avoid potentially serious adverse events.
