"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.

Total osteocalcin levels are independently associated with worse testicular function and a higher degree of hypothalamic-pituitary-gonadal axis activation in Klinefelter syndrome.

PURPOSE: The role of osteocalcin (OCN) in pubertal development, male hypogonadism, and the effect of testosterone (Te) replacement therapy (TRT) remains unclear. We aimed to investigate the total OCN (tOCN) concentrations in male patients with Klinefelter syndrome (KS), a model of adult hypergonadotropic hypogonadism. METHODS: This retrospective longitudinal study investigated 254 male patients with KS (47,XXY) between 2007 and 2021 at an academic referral center, categorized as (1) prepubertal, (2) pubertal, and (3) adults. All prepubertal patients were Te-naïve. Adult patients were subcategorized as (1) eugonadal, (2) hypogonadal, and (3) receiving TRT. We also analyzed 18 adult patients with available tOCN levels before and 3 months after TRT commencement. RESULTS: The tOCN levels varied throughout the lifespan according to pubertal status, were highest in eugonadal and significantly lower in TRT subjects, correlated with both LH (p = 0.017) and FSH levels (p = 0.004) in adults, and significantly declined after 3 months of TRT (p = 0.006) in the adult KS cohort. HPG-axis hormones levels demonstrated no correlation in prepubertal boys. Adjustment for age and body mass index confirmed previous results and revealed significant inverse correlations with total Te (p = 0.004), calculated free Te (p = 0.016), the Te/LH (p = 0.010), and calculated free Te/LH ratios (p = 0.031). CONCLUSION: In KS, a model of male hypergonadotropic hypogonadism, tOCN levels were not associated with gonadal function during normal prepuberty and pubertal development but were associated with worse testicular function and a higher degree of HPG stimulation in adults. TRT acutely reduced tOCN levels in adults.

Tall stature and gigantism in transition age: clinical and genetic aspects-a literature review and recommendations.

PURPOSE: Tall stature is defined as height greater than the threshold of more than 2 standard deviations above the average population height for age, sex, and ethnicity. Many studies have described the main aspects of this condition during puberty, but an analysis of the characteristics that the physician should consider in the differential diagnosis of gigantism-tall stature secondary to a pituitary tumour-during the transition age (15-25 years) is still lacking. METHODS: A comprehensive search of English-language original articles was conducted in the MEDLINE database (December 2021-March 2022). We selected all studies regarding epidemiology, genetic aspects, and the diagnosis of tall stature and gigantism during the transition age. RESULTS: Generally, referrals for tall stature are not as frequent as expected because most cases are familial and are usually unreported by parents and patients to endocrinologists. For this reason, lacking such experience of tall stature, familiarity with many rarer overgrowth syndromes is essential. In the transition age, it is important but challenging to distinguish adolescents with high constitutional stature from those with gigantism. Pituitary gigantism is a rare disease in the transition age, but its systemic complications are very relevant for future health. Endocrine evaluation is crucial for identifying conditions that require hormonal treatment so that they can be treated early to improve the quality of life and prevent comorbidities of individual patient in this age range. CONCLUSION: The aim of our review is to provide a practical clinical approach to recognise adolescents, potentially affected by gigantism, as early as possible.

Molecular study of the presence and transcriptional activity of HPV in semen.

PURPOSE: Human Papillomavirus (HPV) in semen represents a controversial topic. Recent evidence suggests a correlation with poor semen quality, but its detection is still unstandardized in this biological fluid. Thus, the aims of this study were to verify the ability of nested PCR to reveal HPV-DNA in semen; to evaluate association of seminal HPV with sperm parameters and risk factors for infection; to investigate the rate of HPV-DNA positivity in patients with and without risk factors; to assess HPV transcriptional activity. METHODS: We enrolled sexually active men and collected clinical and anamnestic data during andrological and sexually transmitted infections (STIs) evaluation. For each patient, we performed semen analysis and nested PCR to detect HPV-DNA in semen. In positive semen samples, we proceeded with genotyping and RNA quantification to detect HPV transcriptional activity. RESULTS: We enrolled 185 men (36.0 ± 8.3 years), of which 85 with (Group A) and 100 without HPV risk factors (Group B). Nested PCR was able to reveal HPV-DNA in semen, discovering a prevalence of 8.6% (11.8% in Group A and 6% in Group B, respectively). We observed no correlation between sperm quality and seminal HPV. Genital warts and previous anogenital infection were significantly associated with the risk of HPV positivity in semen. Moreover, no viral transcriptional activity was detected in positive semen samples. CONCLUSIONS: Our study suggests that searching for seminal HPV could be important in patients both with and without risk factors, especially in assisted reproduction where the risk of injecting sperm carrying HPV-DNA is possible.

The effects of non-andrological medications on erectile dysfunction: a large single-center retrospective study.

PURPOSE: To evaluate the association among andrological diseases at the first outpatient visit and the medications taken by patients for other comorbidities, as well as the differential impact between specific medication and relative comorbidities. METHODS: This is a single-center retrospective study based on subjects who referred to the Andrology Unit with a well-defined andrological diagnosis. RESULTS: A total of 3752 subjects were studied (mean age ± DS 46.2 ± 16.5 years). A total of 19 categories of andrological diseases and 110 type of medications for other comorbidities were identified. ED was the most frequent andrological pathology at the first andrological examination (28.7%), followed by infertility (12.4%). The couple of variables that were statistically significant in the univariate association analysis (p < 0.001) were: ED and (a) antihypertensives; (b) antihyperglycemics; (c) lipids-lowering; (d) psychotropics. The univariate and multivariate regression analyses confirmed the association. All the related comorbidities were also significantly associated with the univariate analysis, and all remained significantly associated with multivariate analysis. A multivariate analysis was also conducted to analyze the association between ED and the following pairs of variables "DM-antihyperglycemics", "dyslipidemia-lipids-lowering", and "hypertension-antihypertensives". In all cases, the pathology, but not the specific treatment, was significantly associated with ED. CONCLUSION: ED is significantly associated with antihypertensive, antihyperglycemic, lipid-lowering, psychotropic drugs' intake. Anyway, ED appears to be more related to the diseases than to the specific therapies. The definitive cause/effect relationship should be established based on future prospective studies.

Sellar and parasellar lesions in the transition age: a retrospective Italian multi-centre study.

BACKGROUND: Sellar/parasellar lesions have been studied in the adult and paediatric age range, but during the transition age their epidemiology, clinical manifestations, management and treatment outcomes have been poorly investigated. MATERIALS AND METHODS: An Italian multicentre cohort study, in which hospital records of patients with diagnosis of sellar/parasellar lesions during the transition age and young adulthood (15-25 years), were reviewed in terms of prevalence, clinical and hormonal features at diagnosis, and outcomes where available. Both pituitary neuroendocrine tumours (pituitary tumours, Group A) and non-endocrine lesions (Group B) were included. RESULTS: Among Group A (n = 170, 46.5% macroadenomas), the most frequent were prolactin and GH-secreting tumours, with a female predominance. Among Group B (n = 28), germinomas and Rathke cells cysts were the most common. In Group A, the most frequent hormonal deficiency was gonadal dysfunction. Galactorrhoea and amenorrhoea were relatively common in female patients with prolactinomas. Pre-surgical diabetes insipidus was only seen in Group B, in which also hormone deficiencies were more frequent and numerous. Larger lesions were more likely to be seen in Group B. Patients in Group B were more frequently male, younger, and leaner than those of Group A, whereas at last follow-up they showed more obesity and dyslipidaemia. In our cohort, the percentage of patients with at least one pituitary deficiency increased slightly after surgery. CONCLUSIONS: The management of sellar/parasellar lesions is challenging in the transition age, requiring an integrated and multidisciplinary approach. Hormone and metabolic disorders can occur many years after treatment, therefore long-term follow-up is mandatory.

Male reproductive health after 3 months from SARS-CoV-2 infection: a multicentric study.

PURPOSE: While SARS-CoV-2 infection appears not to be clinically evident in the testes, indirect inflammatory effects and fever may impair testicular function. To date, few long-term data of semen parameters impairment after recovery and comprehensive andrological evaluation of recovered patients has been published. The purpose of this study was to investigate whether SARS-CoV-2 infection affect male reproductive health. METHODS: Eighty patients were recruited three months after COVID-19 recovery. They performed physical examination, testicular ultrasound, semen analysis, sperm DNA integrity evaluation (TUNEL), anti-sperm antibodies (ASA) testing, sex hormone profile evaluation (Total testosterone, LH, FSH). In addition, all patients were administered International Index of Erectile Function questionnaire (IIEF-15). Sperm parameters were compared with two age-matched healthy pre-COVID-19 control groups of normozoospermic (CTR1) and primary infertile (CTR2) subjects. RESULTS: Median values of semen parameters from recovered SARS-CoV-2 subjects were within WHO 2010 fifth percentile. Mean percentage of sperm DNA fragmentation (%SDF) was 14.1 ± 7.0%. Gelatin Agglutination Test (GAT) was positive in 3.9% of blood serum samples, but no positive semen plasma sample was found. Only five subjects (6.2%) had total testosterone levels below the laboratory reference range. Mean bilateral testicular volume was 31.5 ± 9.6 ml. Erectile dysfunction was detected in 30% of subjects. CONCLUSION: Our data remark that COVID-19 does not seem to cause direct damage to the testicular function, while indirect damage appears to be transient. It is possible to counsel infertile couples to postpone the research of parenthood or ART procedures around three months after recovery from the infection.

Adverse pathophysiological influence of early testosterone therapy on the testes of boys with higher grade sex chromosome aneuploidies (HGAs): a retrospective, cross-sectional study.

PURPOSE: Higher grade aneuploidies (HGAs) of the male sex chromosomes are a rare genetic group of pathologies caused by nondisjunction meiotic events. The aim of this study was to evaluate the impact of early androgenic therapy on the testicular secretory hormone profile, and the pathophysiological implications. PATIENTS AND METHODS: In this cross-sectional study, 18 HGA subjects aged 6-8 years were recruited. They were divided into two groups, based on whether or not they had previously undergone testosterone therapy (group 1: 11 untreated subjects; group 2: 7 treated subjects). Serum FSH, LH, testosterone (T), inhibin B (INHB) and anti-Müllerian hormone (AMH) were determined, and auxological parameters were assessed. Five group 1 patients and four group 2 patients were treated with hCG (human chorionic gonadotropin) for inguinal cryptorchidism; their hormone profile and auxological parameters were assessed both pre- and post-hCG treatment. RESULTS: Group 1 subjects showed significantly higher testicular volume and higher levels of AMH and INHB (p < 0.0001). Subjects who had undergone hCG therapy showed a significantly higher testicular volume, penis length (respectively, p = 0.008 and p = 0.0005 for group 1 and p = 0.04 and p = 0.001 for group 2) and T (p = 0.005 for group 1 and p = 0.004 for group 2). CONCLUSIONS: HGA patients undergoing early testosterone therapy show an earlier and persistent suppression of testicular secretory function. At this age, the testes are still responsive to stimulation with hCG. The selection of patients to be treated must be accompanied by a thorough clinical and hormonal evaluation.

From mini-puberty to pre-puberty: early impairment of the hypothalamus-pituitary-gonadal axis with normal testicular function in children with non-mosaic Klinefelter syndrome.

PURPOSE: Klinefelter syndrome (KS) is a genetic disorder caused by the presence of an extra X chromosome in males. The aim of this study was to evaluate the hypothalamic-pituitary-gonadal (HPG) axis and the clinical profile of KS boys from mini-puberty to early childhood. PATIENTS AND METHODS: In this retrospective, cross-sectional, population study, 145 KS boys and 97 controls aged 0-11.9 years were recruited. Serum FSH, LH, testosterone (T), Inhibin B (INHB), sex hormone binding globulin (SHBG) and anti-Müllerian hormone (AMH) were determined. Auxological parameters were assessed. To better represent the hormonal and clinical changes that appear in childhood, the entire population was divided into 3 groups: ≤ 6 months (group 1; mini-puberty); > 6 months and ≤ 8 years (group 2; early childhood); > 8 and ≤ 12 years (group 3; mid childhood). RESULTS: During mini-puberty (group 1), FSH and LH were significantly higher in KS infants than controls (p < 0.05), as were INHB and T (respectively p < 0.0001 and p < 0.005). INHB was also significantly higher in KS than controls in group 2 (p < 0.05). AMH appeared higher in KS than in controls in all groups, but the difference was only statistically significant in group 2 (p < 0.05). No significant differences were found in height, weight, testicular volume, and penile length. CONCLUSIONS: No hormonal signs of tubular or interstitial damage were found in KS infants. The presence of higher levels of gonadotropins, INHB and testosterone during mini-puberty and pre-puberty may be interpreted as an alteration of the HPG axis in KS infants.

Predictors of malignancy in high-risk indeterminate (TIR3B) cytopathology thyroid nodules.

PURPOSE: The classification of indeterminate cytopathology at thyroid fine-needle-aspiration (FNA) has been updated to reduce the number of unnecessary surgery; the 2014 Italian classification introduced the low-risk (TIR3A) and high-risk (TIR3B) subcategories. Aim of this study was to identify the ultrasonographic (US), clinical and cytological predictors of malignancy among TIR3B nodules from a single institution. METHODS: A prospective observational study including 1844 patients who underwent thyroid FNA from June 2014 to January 2019. Ultrasonographic, clinical and cytological features were recorded. All TIR3B diagnoses were referred to surgery. According to final histology, patients were divided into thyroid cancer (TC) or benign nodules. Chi-square test, or Fisher exact test when appropriate, were used to compare groups and logistic regression analyses were used to determine independent predictors of malignancy. RESULTS: Of 1844 FNAs, 96 (5.2%) were TIR3B. Histology report was available in 65. Among them, 25 (38.5%) were TC. Predictors of TC were nodule size < 20 mm [Odds Ratio (OR) = 5.88, 95% CI 1.91-18.11, p = 0.002], absence or weak intralesional flow [OR = 0.3, 95% CI 0.09-0.77, p = 0.015], microcalcifications [OR = 6.5, 95% CI 1.90-21.93, p = 0.003] at US; nuclear inclusions [OR = 25.3, 95% CI 1.34-476.07, p = 0.031] and chromatin clearing [OR = 3.7, 95% CI 1.27-10.99, p = 0.017] at cytopathology. Patients aged < 55 years had a significantly higher risk of TC [OR = 9.7, 95% CI 2.79-34.07, p < 0.001]. In multivariate analysis, age < 55 and nodule size < 20 mm resulted as independent risk factors. CONCLUSIONS: Patients < 55 years receiving a diagnosis TIR3B on nodules < 20 mm, with microcalcifications, showing specific nuclear atypia at cytopathology are more likely to have TC. Combining US, cytological and clinical features could help determining which patients with a TIR3B diagnosis should be referred to surgery.

Monitoring testosterone replacement therapy with transdermal gel: when and how?

PURPOSE: Testosterone replacement therapy (TRT) is recommended for the treatment of most cases of male hypogonadism. Transdermal testosterone (T) gels are commonly used in clinical practice; however, there is little evidence concerning how to monitor dosage to bring and maintain serum T levels in the normal physiologic range. METHODS: We examined 30 hypogonadal patients undergoing treatment with 40 mg/day transdermal 2% testosterone gel. After a week from treatment onset, all patients underwent a total of four measurements to assess serum total T, bioavailable T and free T at + 2 h (samples A and A') and + 23 h (samples B and B'). RESULTS: No significant difference was found concerning total, free and bioavailable T between the two samples taken at the same time points (A vs A' and B vs B'). A repeated-measures mixed effects regression model showed significantly lower serum levels of total, free and bioavailable T at + 23 h compared to + 2 h (total T, ß = - 3.050 ± 0.704, p < 0.001; free T, ß = - 85.187 ± 22.746, p < 0.001; bioavailable T, ß = - 1.519 ± 0.497, p = 0.003) without a significant between-sample variability. Serum T > 3.5 ng/ml at + 2 h was reached in 21/30 patients (70%), but only 11 (36.7%) still had adequate serum T at + 23 h. CONCLUSION: Assessment of TRT with transdermal gels at its peak and at its minimum could be useful in providing a finely tailored treatment for hypogonadal men, both preventing supra-physiological levels and maintaining adequate concentrations through the day.

Profiling of selenium absorption and accumulation in healthy subjects after prolonged L-selenomethionine supplementation.

PURPOSE: Autoimmune thyroiditis and its complications for the reproductive system are a growing problem. Selenium is a common ingredient in numerous food supplements recommended for thyroiditis and pregnancy. A fast, simple method to measure serum selenium concentration will improve knowledge of its pharmacokinetics and toxicity. AIM: To validate a useful method to measure serum selenium concentration and to study selenium absorption and accumulation in a prospective interventional study of prolonged treatment. METHODS: Thirty healthy volunteers received a single dose of L-selenomethionine one tablet (83 mcg) (Phase 1), a single dose of two tablets (Phase 2), and two tablets daily for 14 days (Phase 3). Total selenium and selenium time profiles were generated by serial sampling (T0, T3, T6, T12, and T24 hours after ingestion-Phases 1 and 2; and T0 and T24 hours-Phase 3). Selenium concentration was investigated by open-vessel acid digestion of small serum volumes followed by hydride generation atomic fluorescence spectroscopy analysis. RESULTS: There was a significant increase in serum selenium concentration (mcg/L) in all treatment phases. Significantly increased levels were reached at T3 in Phase 1 (baseline: 76.5 ± 2.47; T3: 82.8 ± 3.28) and at T6 in Phase 2 (83.8 ± 3.46). They remained significantly increased at T12 in Phase 1 and T24 in Phase 2 (79.03 ± 2.69). There was significant selenium accumulation after prolonged intake (14 days) (102.13 ± 5.61). CONCLUSIONS: Prolonged selenomethionine administration increases circulating blood selenium concentration and hydride generation atomic fluorescence spectroscopy enables its accurate quantification.

Fluid intelligence, traits of personality and personality disorders in a cohort of adult KS patients with the classic 47, XXY karyotype.

PURPOSE: Klinefelter's syndrome (KS) is associated with specific neurobehavioral features and personality traits. The aim of our study was to investigate fluid intelligence, personality traits and personality disorders (PD) and possible correlations with testosterone in a cohort of adult KS patients. METHODS: We analyzed 58 adult KS patients with the classic 47, XXY karyotype. The Structured Clinical Interview for axis II disorders was used to assess DSM IV personality disorders. Personality traits were assessed using MMPI-2. Fluid intelligence was tested by using Raven's Standard Progressive Matrices (SPM) Test. Testosterone blood concentration was measured by CMIA. RESULTS: PD prevalence was 31%. Four altered MMPI scales (Social Responsibility, Dominance, Ego Strength and Repression) were found in more than 40% of patients. Overcontrolled hostility and MacAndrew Alcoholism Scale-Revised scales were altered in the PD- group only. Biz-Odd Thinking and Post-Traumatic Stress Disorder scale were associated with the presence of personality disorder. The raw SPM score was 44 ± 10.8 without any significant correlation with testosterone. No significant difference in mean age, SPM raw score and MMPI score was observed between eugonadal, hypogonadal and treated patients. CONCLUSIONS: Most KS patients had average fluid intelligence. PD prevalence was higher than in the general population. Testosterone was not correlated with fluid intelligence, personality traits or PD, but a reduction in marital distress was observed in treated patients. This could suggest that testosterone therapy can improve physical symptoms and this effect could also improve relationship abilities and wellness awareness.

Everything you ever wanted to know about phosphodiesterase 5 inhibitors and the heart (but never dared ask): How do they work?

INTRODUCTION: Phosphodiesterase 5 inhibitors (PDE5i) were developed while investigating novel treatments for coronary artery disease, but their andrological side effects shifted their indication toward the management of erectile dysfunction. Although PDE5i are now also indicated for pulmonary arterial hypertension and there are mounting preclinical and clinical evidences about their potentially beneficial cardiac effects, their use remains controversial and the involved mechanisms remain unclear. MATERIALS AND METHODS: This review aimed to analyze the effects of PDE5i administration in various animal and humans models of cardiovascular diseases. RESULTS: Animal studies have shown that PDE5i have protective effects in several models of cardiac disease. In humans, some studies showed that PDE5i improves microvascular and endothelial dysfunction and exerts positive effects in different samples of cardiovascular (CV) impairment. In contrast, other studies found no benefit (and no harm) in heart failure with preserved ejection fraction. The discrepancies in these findings are likely related to the fact that the mechanisms targeted by PDE5i in human disease are still poorly understood and the target population not yet identified. The mechanisms of actions herein reviewed suggest that hypertrophy, microvascular impairment, and inflammation, should be variably present for PDE5i to work. All these conditions frequently coexist in diabetes. A gender responsiveness has also been recently proposed. CONCLUSIONS: Continuous PDE5 inhibition may exert cardioprotective effects, improving endothelial function and counteracting cardiac remodeling in some but not all conditions. A better patient selection could help to clarify the controversies on PDE5i use for CV disorders.

Acute endothelial response to testosterone gel administration in men with severe hypogonadism and its relationship to androgen receptor polymorphism: a pilot study.

PURPOSE: Testosterone (T) exerts different effects on the cardiovascular system. Despite this knowledge, the acute vascular effect of androgen remains still poorly understood. METHODS: We investigated the acute effects of T on vascular function in ten men (18-40 years age) with hypogonadism and severe hypotestosteronemia [serum total testosterone (TT) = 0.6 ± 0.3 ng/mL]. In a 4-day double-blind, randomized, placebo-controlled crossover study, we administered 80 mg daily dose of transdermal-T gel (TG) and evaluated endothelial variations with Endopat2000 (reactive hyperemia index, RHI and the augmentation index, AI); also, CAG repeat polymorphism in exon 1 of the androgen receptor gene was investigated. RESULTS: After TG administration, RHI significantly improved at 4 h (p < 0.05), while AI improvement was recorded at 4 and 96 h, also when adjusted for heart rate (AI@75; p < 0.01 and p < 0.001, respectively). Direct relationships between ΔT, ΔDHT and ΔRHI variations (r = 0.37, p < 0.01; r = 0.17, p < 0.05, respectively) as well as between "CAG repeats" length and ΔLnRHI at 96 h (p < 0.03, r (2) = 0.47) were found. An inverse relationship between ΔT and ΔAI (p < 0.01, r = -0.35) and ΔAI@75 (p < 0.01, r = -0.38) were found. CONCLUSION: Administration of TG causes an acute vasodilation and improves arterial stiffness probably due to non-genomic actions of T. Endothelial vasodilatory response was more pronounced depending on higher plasma TT and DHT levels attained. Clinical implications in elderly frail populations are discussed.

Predictors and clinical consequences of starting androgen therapy in men with low testosterone: results from the SIAMO-NOI registry.

PURPOSE: Management of late onset hypogonadism (LOH) is not homogenous. The aim of the study is to observe the management of patients with low testosterone (T) in highly specialized Italian centres. METHODS: The SIAMO-NOI is an observational longitudinal disease registry for the evaluation of the clinical management of patients with low T levels (total T < 12 nmol/L, calculated free T < 225 pmol/l or already in treatment) in 15 Italian centers members of the Italian Society for Andrology and Sexual Medicine (SIAMS). Clinical and biochemical data were collected for four visits during 12 months of observation. RESULTS: 432 patients (mean age 50.9 ± 14.9 years) were enrolled. Of them, 247 men were receiving androgen therapy, whereas 145 were naive. After the first visit (V0), 80 men started androgen therapy, whereas 55 remained untreated during the entire observation. Younger age [odds ratio (OR) 0.57 (0.35-0.92)], total T < 8 nmol/l [OR 4.69 (1.59-13.81)], complaining at least one sexual symptom [OR 11.55 (2.01-66.35)] and reporting more severe lower urinary tract symptoms [OR 1.27 (1.01-1.60)] predicted starting an androgen therapy. Sixty-four men started therapy immediately after V0 and maintained it until the observation end. When compared to V0, they reported an increase in all the domains of the International Index of Erectile Function-15 (IIEF-15), in the sexual and physical subdomains of the Aging Male Scale as well as in the International Prostate Symptom Score. Conversely, the untreated group reported a significant improvement, although lower than the treated group, only in the erectile function domain of the IIEF-15. CONCLUSIONS: Management of LOH in SIAMS centres is in line with the international guidelines and the newest knowledge about the role of T on prostate health. Androgen therapy is associated with an improvement in all the aspects of sexual life and in the perception of physical strength.

SIAMS survey on sexological screening during the assisted reproductive technologies in Italy.

PURPOSE: The assessment of sexual function is fundamental to the Assisted Reproductive Technology (ART). Nevertheless, it is still not a common clinical routine among infertility centres. The aim of this survey is to describe the main aspects of sexological screening that are considered in Italian centres of ART. METHODS: After the consensus of the Italian Society of Andrology and Sexual Medicine (SIAMS), a mailing list of reproductive medicine centres was created. Then, we sent a questionnaire concerning the essential characteristics of sexological screening. The respondents to compilers of the questionnaire sent back the information from their centres, and an analysis of absolute frequencies and percentages was performed. RESULTS: First, 16 centres completed and returned the questionnaire, while 5 ignored the invitation. The main findings concerned the wide use consideration of vardenafil 10 mg (68.7%; 11/16) for the treatment of erectile dysfunction in comorbidity with reproductive problems, the diffuse administration of International Index of Erectile Function (68.2%; 11/16) and Structured Interview for the Erectile Dysfunction (50%; 8/16) as psychometric tools and lesser use of Female Sexual Function Index (31.2%; 5/16) for the evaluation of female sexuality in the infertile couple. CONCLUSIONS: To conclude, we noticed a major focus on male sexuality and the eventual treatment or evaluation of sexual dysfunction compared to female sexuality. This aspect highlights an important issue for clinical practice to strongly consider and eventually reinforce. In this regard, improvement of the assessment and treatment of possible female sexual problems in reproductive medicine seems necessary.

Propionyl-L-carnitine, L-arginine and niacin in sexual medicine: a nutraceutical approach to erectile dysfunction.

The application of nutraceuticals in the field of male sexual function -in particular for erectile dysfunction (ED)--remains relatively underexplored. In a group of 54 unselected men (35-75 years), consecutively presenting to our ED clinic and naive to other ED treatments, we carried out a single-blind, one-arm study to evaluate the effects of a 3-month supplementation with propionyl-L-carnitine, L-arginine and niacin on their sexual performance. All patients had the short-international index of erectile function (IIEF) questionnaire, global assessment questions (GAQs) and routine laboratory testing, at baseline and 3 months afterward. 51 (92%) patients of 54 completed the entire study period. After 3 months of treatment, a small, but statistically significant improvement in total and single items of the IIEF was found (Δ = 5.7 ± 4.1 P < 0.01). Analyses on GAQs revealed that treatment improved erections in 40% of cases, with a partial response occurring in up to 77% of subjects enrolled. These preliminary findings indicate that the favourable cardiovascular effects of nutraceuticals might also reflect on male sexual function with possible implication in the treatment and prevention of ED. This study documents a considerable patient's interest toward nutritional supplementation--as first-line or adjunctive treatment to PDE5 inhibitors--that goes beyond the measurable increment in penile rigidity.

Strategies and advantages of early diagnosis in Klinefelter's syndrome.

Nearly 70 years after its description, Klinefelter's syndrome (KS) remains a largely undiagnosed condition. In addition to its typical characteristics of increased follicle-stimulating hormone secretion and small and firm testes, the syndrome presents an extremely wide spectrum of phenotypes. This could be explained by the possible presence of chromosomal mosaicism, androgen receptor polymorphisms and related heterogeneous endocrine abnormalities. The varied but relatively mild physical abnormalities also explain why many patients do not receive clinical attention until adulthood, when they seek medical advice on small testes or infertility. Diagnosis is also hindered by the low awareness of the disease among health professionals. This paper aims to review the possible signs of KS at different stages of life that could help achieve an early (or at least earlier) diagnosis. It has been demonstrated that the early diagnosis of KS improves patients' quality of life and enables better medical treatment. To achieve this, it is crucial to increase both medical and general awareness of the disease, including through use of the media and patients' associations.

Thyroid profile during the alternative Sunitinib dosing 2/1 schedule in metastatic renal cell carcinoma.

PURPOSE: Hypothyroidism is a common side effect of Sunitinib (SUN) treatment in metastatic renal cell carcinoma (mRCC) patients. We aimed to evaluate thyroid profile during the alternative 2/1 SUN treatment schedule and to assess the predictive value of hypothyroidism in terms of survival. METHODS: We performed a prospective observational study enrolling 42 consecutive mRCC patients starting first-line alternative SUN dosing 2/1 schedule. Thyroid function was assessed at baseline and during the first three SUN cycles (1 cycle = 6 weeks = 2 ON/1 OFF + 2 ON/1 OFF), and then after 6 and 12 months. Thyroid ultrasound was performed at baseline and after 3, 6, and 12 months. RESULTS: Subclinical hypothyroidism developed in 24% of patients during the first cycle; in other 24% in the second cycle and in 14% in the third cycle. The highest TSH values were reached during the second cycle, ON phase (6.58 ± 5.74 µI U/l). We observed a reduction in thyroid size, in echogenicity and in parenchymal perfusion in all patients. Progression-free survival (PFS) tended to be longer in patients with TSH ≥ 5 µI U/ml during the second cycle (p = 0.069). TSH level was an independent risk factor for PFS in men (p = 0.009) but not in women (p = 0.285). CONCLUSIONS: This is the first study investigating functional and morphological effects on thyroid during the alternative 2/1 SUN schedule in mRCC patients. We detected an early onset of subclinical hypothyroidism, observing the association between TSH ≥ 5 µI U/ml and: (i) longer PFS in men; (ii) progressive decrease of thyroid size in absence of significant changes in autoimmune thyroid profile.
