RESUMO

BACKGROUND: Hypoactive Sexual Desire Disorder (HSDD) is a frequent sex-related problem in women; however, a specific tool to characterize HSDD subtypes based on sexual inhibitory and excitatory factors is still lacking. AIM: (1) To find a cutoff value in Sexual Inhibition Scale (SIS)/Sexual Excitation Scale (SES) scores predicting a diagnosis of HSDD in women consulting for sexual symptoms, (2) to explore the sexual inhibitory and excitatory profiles in women referred to a clinic for female sexual dysfunction by stratifying the sample according to the newfound cutoffs, and (3) to identify biopsychosocial factors significantly associated with the 2 profiles. METHODS: An overall 133 women consulting for sexual symptoms were retrospectively evaluated for clinical, biochemical, and psychosexologic data collected at the first visit. A subgroup of 55 women treated with transdermal testosterone was retrospectively analyzed at baseline and the 6-month visit. OUTCOMES: Patients underwent physical and laboratory examinations and completed the SIS/SES, Female Sexual Function Index, Female Sexual Distress Scale-Revised, Emotional Eating Scale, and Middlesex Hospital Questionnaire. RESULTS: Specific cutoffs for SIS1 (≥32.5; indicating threat of performance failure) and SES (≤46.5) predicted HSDD diagnosis with an accuracy of 66.4% (P = .002) and 68.7% (P < .0001), respectively. Patients with impaired SIS1 scores showed higher distress and psychopathologic symptoms, while those with impaired SES scores demonstrated lower desire and arousal and a negative association with some metabolic and hormonal parameters. SES score also showed a significant predictive value on testosterone treatment efficacy for HSDD. CLINICAL TRANSLATION: A better characterization of HSDD would enable individualized treatment based on the main underlying etiologies. STRENGTHS AND LIMITATIONS: Limitations of the study include the small sample size and cross-sectional retrospective design, with the choice of treatment for HSDD limited to transdermal testosterone. Strengths comprise the thorough and multifactorial evaluation of every aspect potentially affecting inhibitory and excitatory components of sexual desire. CONCLUSION: Validated cutoffs of SIS/SES scores could allow deep characterization of women diagnosed with HSDD, thus ensuring better tailoring of therapy and prediction of the probability of response to specific treatments.

RESUMO

Sperm oxidative stress has been extensively associated to male infertility. However, tests to detect this parameter have not been yet introduced in clinical practice and no definitive data are present on the extent of oxidative stress in male infertility. In this study, we used a novel and reliable flow cytometric method to reveal sperm ROS production in subfertile patients (n = 131) and in healthy donors (n = 31). Oxidative stress was higher in subfertile patients (14.22 [10.21-22.08]%) than in healthy donors (9.75 [8.00-14.90]% (p < 0.01)), but no correlation was found with age, semen quality or sDF. We also failed to detect an increase in sperm ROS production with semen viscosity or leukocytospermia, but a sharp impact of semen bacteria was evident (with bacteria: 31.61 [14.08-46.78]% vs. without bacteria: 14.20 [10.12-22.00]%, p < 0.01). Finally, after establishing a threshold as the 95th percentile in healthy donors, we found that 29% of subfertile patients exceeded this threshold. The percentage decreased to 25.56% when we excluded subjects with bacteriospermia and increased to 60.87% when only these patients were considered. In conclusion, 29% of subfertile patients showed an excessive sperm ROS production. Surprisingly, this parameter appears to be independent from routine semen analysis and even sDF determination, promising to provide additional information on male infertility.

RESUMO

Introduction: Galectin-3 is a pro-fibrotic ß-galactoside binding lectin highly expressed in fibrotic liver and implicated in hepatic fibrosis. Selvigaltin (previously known as GB1211) is a novel orally active galectin-3 small molecule inhibitor that has high affinity for galectin-3 (human KD = 25 nM; rabbit KD = 12 nM) and high oral bioavailability in rabbits and man. In this study the efficacy of selvigaltin was investigated in a high fat diet (HFD) rabbit model of metabolic-associated steatohepatitis (MASH). Methods: Male New Zealand White rabbits were individually caged under standard conditions in a temperature and humidity-controlled room on a 12 h light/darkness cycle. After 1 week of regular diet (RD), rabbits were randomly assigned for 8 or 12 weeks to different groups: RD/vehicle, RD/selvigaltin, HFD (8 weeks), HFD/vehicle and HFD/selvigaltin (0.3, 1.0, 5.0 or 30 mg/kg selvigaltin with vehicle/selvigaltin p.o. dosed therapeutically q.d. 5 days per week from week 9 or 12). Liver inflammation, steatosis, ballooning, and fibrosis was measured via blood metabolic markers, histomorphological evaluation [Oil Red O, Giemsa, Masson's trichome, picrosirius red (PSR) and second harmonic generation (SHG)], and mRNA and protein expression. Results: Steatosis, inflammation, ballooning, and fibrosis were all increased from RD to HFD/vehicle groups. Selvigaltin demonstrated target engagement by significantly decreasing galectin-3 levels in the liver as measured via immunohistochemistry and mRNA analysis. Selvigaltin dose-dependently reduced biomarkers of liver function (AST, ALT, bilirubin), inflammation (cells foci), and fibrosis (PSR, SHG), as well as decreasing the mRNA and protein expression of several key inflammation and fibrosis biomarkers (e.g., IL6, TGFß3, SNAI2, collagen). Doses of 1.0 or 5.0 mg/kg demonstrated consistent efficacy across most biological endpoints supporting the current clinical doses of selvigaltin being investigated in liver disease. Discussion: Selvigaltin significantly reduced hepatic inflammation and fibrosis in an HFD rabbit model of MASH following therapeutic dosing for 4 weeks in a dose-dependent manner. These data support the human selvigaltin dose of 100 mg b.i.d. that has been shown to reduce key liver biomarkers during a clinical study in liver cirrhosis.

RESUMO

INTRODUCTION: Several robust epidemiological studies suggest that men are often engaged in sexual relationships with younger women with a variable, age-dependent age difference. However, the ageing process determines a significant worsening of the andrological status, which favors the onset of erectile dysfunction and hypogonadism. OBJECTIVES: To analyze the effects of differences in age between the partners [delta (Δ) age (M - F)] on patients referring to the Andrology Unit of Careggi University Hospital for male sexual dysfunction. MATERIALS AND METHODS: A monocentre cohort of 4055 male subjects was evaluated by SIEDY structured interview. The cross-sectional analysis assessed the psychobiological and relational correlates. The rate of forthcoming major cardiovascular events (MACE) was investigated in the longitudinal analysis. All the models have been adjusted for age, education, lifestyle, and chronic disease score. RESULTS: ∆ age (M-F) shows a stepwise increase, according to the increasing age bands of the male partner. ∆ age (M-F) was associated with a greater number of children, at the cost of more conflictual relationships within the family. The phenotype of these relationships is characterized by the report of a partner with a higher sexual desire and a higher ability to reach climax. Men seeking a younger partner show more often a histrionic personality (p = 0.023) and higher testosterone levels (p = 0.032). However, having a younger partner doesn't improve the ability to obtain a full erection. Kaplan-Maier analysis of a longitudinal subgroup of patients followed longitudinally (N = 1402) for 4.3 ± 2,59 years, showed that patients in the fourth quartile had a higher rate of forthcoming MACE versus those in the first quartile (p = 0.005). DISCUSSION AND CONCLUSION: In subjects with sexual dysfunctions (as in the general population) age-different relationships increase as a function of male ageing. A greater Δ age (M-F) is associated with specific men and relationship features and a higher risk of MACE.

RESUMO

CONTEXT: Data supporting successful and satisfactory penile prosthesis (PP) implantation outcomes are mainly based on subjective, rather than objective, analysis. OBJECTIVE: To systematically review and objectively analyze, all available data related to patient and partner PP satisfaction. EVIDENCE ACQUISITION: An extensive search was performed, including the following key-words: ("penile prosthesis" and "satisfaction"). The search, which accrued data from January 1, 1969, up to July 31, 2023, was restricted to English-language articles including human participants. EVIDENCE SYNTHESIS: Out of 663 retrieved articles, 83 were considered including, 12,132 subjects with a mean age and mean follow-up of 58.6 [range 20; 77.1] years and 47.6 [range 6; 374] months, respectively. Overall, a high patient satisfaction rate was observed 83[80; 86]%. The satisfaction rate increased in subjects with three-piece PP and in those with a higher rate of cardiovascular or neurological diseases and was independent of the patient's age. Partner's satisfaction rate was lower when compared to that observed in men and it increased according to the use of inflatable devices and the presence of patient Peyronie's disease. The long-term complication rate was limited ranging from 3% for erosion to 4.6% when mechanical failure was considered. CONCLUSIONS: Patient and partner satisfaction is excellent and increases with time. The number of complications is limited and is strongly associated with the presence of diabetes mellitus. PATIENT SUMMARY: We found a high couple satisfaction score that was higher when reported by males compared to females. Patient satisfaction increased with time, and it was independent of age.

RESUMO

PURPOSE: To provide the latest scientific knowledge on the efficacy of inositols for improving reproductive disorders in women with and without polycystic ovary syndrome (PCOS) and to reach a consensus on their potential use through a Delphi-like process. METHODS: A panel of 17 endocrinologists and 1 gynecologist discussed 4 key domains: menses irregularity and anovulation, fertility, pregnancy outcomes, and neonatal outcomes. RESULTS: A total of eight consensus statements were drafted. Myo-inositol (Myo) supplementation can be used to improve menses irregularities and anovulation in PCOS. Myo supplementation can be used in subfertile women with or without PCOS to reduce the dose of r-FSH for ovarian stimulation during IVF, but it should not be used to increase the clinical pregnancy rate or live birth rate. Myo supplementation can be used in the primary prevention of gestational diabetes mellitus (GDM), but should not be used to improve pregnancy outcomes in women with GDM. Myo can be preconceptionally added to folic acid in women with a previous neural tube defects (NTD)-complicated pregnancy to reduce the risk of NTDs in newborns. Myo can be used during pregnancy to reduce the risk of macrosomia and neonatal hypoglycemia in mothers at risk of GDM. CONCLUSION: This consensus statement provides recommendations aimed at guiding healthcare practitioners in the use of inositols for the treatment or prevention of female reproductive disorders. More evidence-based data are needed to definitively establish the usefulness of Myo, the appropriate dosage, and to support the use of D-chiro-inositol (DCI) or a definitive Myo/DCI ratio.

RESUMO

BACKGROUND: The history of studies in the field of infertility represents a chapter of great interest in gender issues. OBJECTIVES: This paper aims to delve deep into the historical roots of the aspect of gender inequality related to couple infertility, with a journey back in time, from classical antiquity to the contemporary age, reporting junctions and metaphors linked to particular historical moments as well as to cultural and religious constructs. METHODS: This is a narrative review based on an extensive literature search of publications regarding the role of women in couple infertility over the centuries. RESULTS: Rarely in the ancient world, male infertility was taken into consideration, and the sources deal with it mainly indirectly. This attitude of "blaming" the woman for the lack of children had, in fact, strong social implications, which only the scientific research of recent years has managed to bring back into the context of a more egalitarian approach. CONCLUSIONS: In the "journey" narrated in this article, the reader starts from the responsibility of couple infertility attributed exclusively to women in some ancient societies, whose central role was determined by their ability to procreate, going up to the medicalization of infertility in the contemporary age, which contributed to sharing with men this participation in the impossibility of having children.

RESUMO

The physiological role of prolactin (PRL) in men is still not well defined. The pathological increase is characterized by sexual function impairment along with possible negative consequences in body composition and metabolic profile. Conversely, the clinical significance of reduced PRL levels was only partially investigated or mainly neglected. The present paper aims to summarize and critically discuss possible phenotypes characterizing male subjects with reduced PRL levels. When possible, meta-analytic results were provided. Available data derived from patients seeking medical care for sexual dysfunction as well as from cross-sectional and longitudinal studies showed that low PRL in males is associated with a worse metabolic phenotype (including diabetes mellitus), mood disturbances (including anxiety and depression), and sexual dysfunctions (including psychogenic erectile and ejaculatory dysfunctions). Whether or not these features are direct consequences of reduced PRL levels or whether the latter reflect other pathway impairments such as serotoninergic failure cannot be clarified. The present data, however, emphasize that a deficiency of PRL should be taken into account and need further investigations.

RESUMO

INTRODUCTION: Testosterone deficiency (TD) is relatively common in aging men, affecting around 2% of the general population. Testosterone replacement therapy (TRT) represents the most common medical approach for subjects who are not interested in fathering. AREAS COVERED: This review summarizes advances in TRT, including approved or non-approved pharmacological options to overcome TD. When possible, a meta-analytic approach was applied to minimize subjective and biased interpretations of the available data. EXPERT OPINION: During the last decade, several new TRT formulations have been introduced on the market, including oral, transdermal, and parenteral formulations. Possible advantages and limitations have been discussed appropriately. Anti-estrogens, including selective estrogen modulators or aromatase inhibitors still represent further possible off-label options. However, long-term side effects on sexual function and bone parameters constitute major limitations. Glucagon-like peptide 1 analogues can be an alternative option in particular for massive obesity-associated TD. Weight loss obtained through lifestyle modifications including diet and physical exercise should be encouraged in all overweight and obese patients. A combination of TRT and lifestyle changes can be considered in those subjects in whom a reversal of the condition cannot be expected in a reasonable time frame.

RESUMO

BACKGROUND: Childhood traumatic experiences have been associated with hypersexuality and sexual dysfunctions. However, the mediators of the interactions between these variables should be clarified in men. AIM: This study aimed to investigate the interaction of early traumatic experiences, psychopathology, and sexuality with respect to erectile dysfunction (ED) and hypersexual behavior. The hypothesized model expected that traumatic experiences would be associated with hypersexual behavior and reduced sexual functioning through the mediation of body uneasiness and psychological distress. METHODS: The study was cross-sectional and observational. A total of 317 men were enrolled. Male patients with a primary complaint of ED and an indication for psychiatry referral represented the clinical sample (n = 116; mean ± SD age, 42.82 ± 16.89 years). Clinical classification was assessed with the Structured Interview on Erectile Dysfunction. The second sample (n = 201, 30.82 ± 11.94 years) was recruited from the general population. All participants were administered the following questionnaires: Brief Symptom Inventory, Childhood Trauma Questionnaire-Short Form, Hypersexual Behavior Inventory, Body Uneasiness Test-A, and 5-item International Index of Erectile Function. OUTCOMES: Psychopathology and sexual functioning were assessed by a dimensional approach, and a multivariate model was computed by structural equation model analysis. RESULTS: When compared with the sample from the general population, the clinical sample exhibited a higher prevalence of early traumatic experiences, as measured by scores on the Childhood Trauma Questionnaire-Short Form (45.08 ± 14.25 vs 39.03 ± 10.22, F = 17.63, P < .001), and a higher tendency to engage in hypersexual behaviors (34.63 ± 13.55 vs 30.79 ± 12.44, F = 6.97, P < .01). Structural equation model analysis showed excellent fit indices indicating that early traumatic experiences predicted hypersexual behaviors and ED through the exacerbating mediating effect of body uneasiness and psychopathology. CLINICAL IMPLICATIONS: Clinicians should not limit their attention to the behavioral level when assessing sexual dysfunction in men; rather, they should also consider the complex psychopathologic consequences of childhood trauma. Integrated treatments that address the potential presence of childhood trauma with its wider psychological correlates (eg, emotion dysregulation, body uneasiness) might improve treatment response. STRENGTHS AND LIMITATIONS: The study reports novel data on the relationship among childhood maltreatment, male sexuality, and psychopathologic mediators with a dimensional assessment. However, the assessment was cross-sectional, and causality was mainly derived from previous studies. CONCLUSION: The present study enriches the current literature, strengthening the hypothesis that childhood traumatic experiences significantly shape development and sexuality. Body uneasiness and psychopathology can both tax sexual functioning, as assessed by erectile functioning or hypersexuality.

RESUMO

Several clinical laboratories assess sperm DNA fragmentation (sDF) in addition to semen analysis in male infertility diagnosis. Among tests evaluating sDF, TUNEL (Terminal deoxynucleotidyl transferase dUTP nick end labeling) and SCD (Sperm Chromatin Dispersion) are widely used. Our lab developed a modified version of TUNEL (TUNEL/PI) able to distinguish two sperm populations (PI Brighter and PI Dimmer) differently associated with sperm viability and reproductive outcomes. The aim of this study was to compare sDF levels detected by SCD and TUNEL/PI in the semen samples from 71 male subjects attending our Andrology Laboratory. Our results demonstrate that SCD is less sensitive in determining sDF compared to TUNEL/PI. The statistically significant positive correlation found between sDF evaluated by SCD and PI Dimmer (consisting of all dead spermatozoa) suggests that SCD mainly detects sDF in unviable spermatozoa. We confirmed that most spermatozoa detected by SCD are unviable by performing SCD after incubation in hypo-osmotic medium to discriminate viable and unviable cells in 52 samples. Such results might explain the lower ability of this test in discriminating couples having successful ART outcomes demonstrated in published metanalyses. Overall, our results indicate that SCD is less sensitive in evaluating sDF for diagnostic purposes.

RESUMO

INTRODUCTION: The cardiovascular (CV) safety of testosterone (T) replacement therapy (TRT) is still conflicting. Recent data suggested a TRT-related increased risk of atrial fibrillation (AF). The aim of this study was to systematic review and meta-analyze CV risk related to TRT as derived from placebo controlled randomized trials (RCTs). AREAS COVERED: An extensive Medline, Embase, and Cochrane search was performed. All placebo-controlled RCTs reporting data on TRT-related CV safety were considered. To better analyze the role of T on AF, population-based studies investigating the relationship between endogenous circulating T levels and AF incidence were also included and analyzed. EXPERT OPINION: Out of 3.615, 106 studies were considered, including 8.126 subjects treated with TRT and 7.310 patients allocated to placebo. No difference between TRT and placebo was observed when major adverse CV events were considered. Whereas the incidence of non-fatal arrhythmias and AF was increased in the only trial considering CV safety as the primary endpoint, this was not confirmed when all other studies were considered (MH-OR 1.61[0.84;3.08] and 1.44[0.46;4.46]). Similarly, no relationship between endogenous T levels and AF incidence was observed after the adjustment for confounders Available data confirm that TRT is safe and it is not related to an increased CV risk.

RESUMO

BACKGROUND: Sperm cryopreservation is an important procedure for oligozoospermic subjects at risk of azoospermia and after surgical recovery of spermatozoa in non-obstructive azoospermic men. Conventional procedures for sperm cryopreservation might be, however, not suitable for samples with a very low sperm number. OBJECTIVES: In this pilot study, we investigated the recoveries of sperm motility and viability in severe oligozoospermic subjects (n = 39) after cryopreservation with a tip-microVapour Fast Freezing, a procedure previously developed by our group for men with good semen quality. Sperm DNA fragmentation was also evaluated in a second group of oligozoospermic samples (n = 16). MATERIALS AND METHODS: We used a Vapour Fast Freezing procedure using 10 µL tips as carrier, and Test Yolk Buffer as freezing medium (tip-microVapour Fast Freezing). In a subset of samples (n = 22), we compared recovery of motility and viability as obtained with tip-microVapour Fast Freezing and with a Vapour Fast Freezing procedure using 500 µL straws. Sperm DNA fragmentation was evaluated by the sperm chromatin dispersion test. RESULTS: We found a recovery rate (median [interquartile range]) of 0.29 (0.13-0.41) for progressive motility, 0.30 (0.21-0.52) for total motility and 0.48 (0.29-0.60) for viability. Interestingly, we observed that samples with the poorest motility were apparently less damaged by freezing/thawing. In a subset of samples (n = 22), we directly compared values of viability, progressive motility and total motility by freezing/thawing with tip-microVapour Fast Freezing and Vapour Fast Freezing conducted with 500 µL straws. We found much better values of all sperm parameters in samples after freezing/thawing with tip-microVapour Fast Freezing than with Vapour Fast Freezing in 500 µL straws: that is, progressive motility: 7.00 (3.00-8.50)% versus 2.00 (0.00-4.25)%, p < 0.001; total motility: 12.00 (8.00-16.25)% versus 6.50 (1.00-9.25)%, p < 0.001; viability: 29.75 (23.75-45.25) versus 22.50 (13.75-28.13), p < 0.001, respectively. In the second group of oligozoospermic samples, we found that tip-microVapour Fast Freezing produced lower levels of sperm DNA fragmentation than straws (33.00 [19.75-36.00]% vs. 36.00 [22.75-41.87]%, p < 0.001). DISCUSSION AND CONCLUSION: Tip-microVapour Fast Freezing appears to be a very promising method to cryopreserve semen samples from severe oligozoospermic patients.

RESUMO

INTRODUCTION: Obesity negatively impact on the metabolism of sex hormones, leading to reduced testosterone serum levels. However, how the obesity could negatively impact on the overall gonadal function, particularly on male fertility, remained unclear so far. OBJECTIVE: To systematically review evidences regarding the influence of body weight excess on the sperm production. METHODS: A meta-analysis was conducted, searching all prospective and retrospective observational studies reporting male subjects older than 18 years old, with body weight excess from overweight to severe obesity were considered. Only studies using the V edition of the World Health Organization (WHO) manual for semen analysis interpretation were considered. No specific interventions were considered. Search was focused on studies comparing overweight/obese to normal weight subjects. RESULTS: Twenty-eight studies were considered. Total sperm count and sperm progressive motility were significantly lower in overweight compared to normal weight subjects. Meta-regression analyses demonstrated that patients' age impacted on sperm parameters. Similarly, obese men showed lower sperm concentration, total sperm number, progressive and total motilities, and normal morphology lower than normal weight subjects. Reduced sperm concentration in obese men was influenced by age, smoking habit, varicocele, and total testosterone serum levels at meta-regression analyses. CONCLUSIONS: The male potential fertility is reduced in subjects with increased body weight, compared to normal weight men. The higher was the increased body weight, the worst was the sperm quantity/quality. This result comprehensively included obesity among non-communicable risk factor for male infertility, shedding new lights on the negative impact of increased body weight on overall gonadal function.

RESUMO

BACKGROUND: Although it has been assumed that chronic cannabis use may have an unfavorable impact on male sexual function and its metabolic correlates, evidence from clinical studies remains inconclusive. OBJECTIVE: To investigate the relationship between cannabis use and sexual behavior, anthropometrics and metabolic/vascular profiles in a large series of men evaluated for sexual dysfunction. METHODS: A total of 4800 men (mean age 50.8 years) attending an andrology outpatient clinic for sexual dysfunction were studied. Sexual symptoms, hormonal, metabolic, and instrumental (penile color Doppler ultrasound, PCDU) parameters were evaluated according to the reported habitual use of recreational substances (no use, 1-2 joints/week, >2 joints/week, and use of illicit drugs other than cannabis). RESULTS: When compared with non-users, cannabis users were younger and exhibited a lower prevalence of comorbidities as well as better PCDU parameters, despite reporting higher alcohol and tobacco consumption. After adjustment for confounders, cannabis use was associated with a greater instability in the couple's relationship and a higher frequency of masturbation. In addition, the group smoking >2 joints/week showed a significantly lower body mass index than both controls and users of substances other than cannabis. Men who reported using recreational drugs (either cannabis or other) exhibited significantly lower levels of both total and low-density lipoprotein cholesterol than non-users. At the PCDU, smoking 1-2 joints/week was associated with significantly higher dynamic peak systolic velocity than both non-drug use and use of >2 joints/week. Prolactin levels were significantly higher in individuals smoking 1-2 joints/week and in those who used substances other than cannabis when compared with controls, whereas no difference in total testosterone levels was observed. DISCUSSION: In men with sexual dysfunction, mild cannabis consumption may be associated with a more favorable anthropometric and lipid profile and with a better penile arterial vascular response to intracavernous prostaglandin injection.

RESUMO

INTRODUCTION: Functional hypogonadism is frequently found in obese men, particularly those with metabolic complications. Several possible therapeutic approaches could be considered. AREAS COVERED: An extensive search on Medline, Embase, and Cochrane databases was performed to retrieve the available studies assessing the change of testosterone (T) and sexual function upon dieting or physical activity programs, as well as glucagon-like peptide 1 analogues. The role of lifestyle interventions associated with T replacement therapy (TRT) was also evaluated. The expert opinion provided here has been corroborated by meta-analyzing the results of the retrieved studies. EXPERT OPINION: Current evidence supports the beneficial role of lifestyle modifications in increasing T and improving sexual function as a function of weight loss. While dieting programs are associated with greater effects in younger populations, physical exercise has major effects in older ones. Among the dieting programs, a very low-calorie ketogenic diet shows the best results; aerobic or endurance physical exercise perform similarly. The advantages of functional hypogonadism in lifestyle modifications are empowered by the association with TRT. Therefore, TRT may be a valuable complementary strategy to increase muscle mass and facilitate physical exercise while improving sexual symptoms, thus favoring the motivation and compliance for lifestyle interventions.

RESUMO

BACKGROUND: Hypoactive sexual desire disorder (HSDD) in premenopausal women involves biological, psychological, and social aspects. In the European Society for Sexual Medicine meeting in Rotterdam in February 2023, several leading experts in the field discussed the multifaceted nature of this disorder and the state of the art regarding treatment at a round table. This review reflects the information discussed at this event and further discusses current controversies. SUMMARY: HSDD is the most prevalent female-estimated sexual disorder reported by 28% of the 40% premenopausal women with sexual dysfunction. Flibanserin and bremelanotide are the only approved medications to treat HSDD in the USA, and none are approved in Europe. Lybrido, Lybridos, and Lorexys are under development. There are several psychological factors with impact in sexual desire, including depression and sexual abuse. Feminine sexual scripts, the pleasure gap, and structural inequalities also affect sexual desire. Evidence strongly supports the value of combining medical and psychological approaches in the treatment of HSDD, but there is ongoing controversy regarding the pharmacological treatment of young women with HSDD. However, some women seem open and would like to have access to drug treatment. KEY MESSAGES: The treatment of HSDD in young women requires a mixed treatment approach that addresses the disorder's complexity. Despite clinicians seeming to be divided between using pharmacological and/or psychosocial approaches, some women might respond better to one type of intervention over the others. This calls for the development of tools that assess the best approach for each person, including their will and informed choice.

RESUMO

CONTEXT: The role of body modifications induced by gonadal suppression in transgender and gender diverse adolescents on psychological functioning has not yet been evaluated. OBJECTIVE: The main aim of the present study was to explore several hormone, physical and psychological functioning changes during gonadotropin-releasing hormone analog (GnRHa) treatment in transgender and gender diverse adolescents (TGDAs). The potential relationship between the physical and hormone effects of GnRHa and psychological well-being, along with its magnitude, was assessed for the first time. METHODS: This prospective multidisciplinary study included 36 TGDA (22 assigned female at birth, and 14 assigned male at birth) who received psychological assessment followed by triptorelin prescription after referring to the Florence Gender Clinic. This study consisted of 3 time points: first referral (T0), psychological assessment (T1); and treatment with intramuscular injections of triptorelin for 3 up to 12 months (T2). Psychometric questionnaires were administered at each time point, and clinical and biochemical evaluations were performed at T1 and T2. RESULTS: The following results were found: (1) GnRHa showed efficacy in inhibiting puberty progression in TGDAs; (2) an increase in psychopathology was observed before starting GnRHa (T1) compared with baseline levels; (3) during GnRHa treatment (T2), a significant improvement in psychological functioning, as well as decrease in suicidality, body uneasiness, depression, and anxiety levels were observed; (4) hormone and physical changes (in terms of gonadotropin and sex steroid levels, height and body mass index percentiles, waist-hip ratio, and acne severity) observed during triptorelin treatment significantly correlated with a reduction in suicidal ideation, anxiety, and body image concerns. CONCLUSION: Psychological improvement in TGDA on GnRHa seems to be related to the objective body changes induced by a GnRHa. Therefore, the rationale for treatment with a GnRHa may not only be considered an extension of the evaluation phase, but also the start of a medical (even if reversible) gender-affirming path, especially in TGDAs whose puberty has already progressed.

RESUMO

INTRODUCTION: The specific role of testosterone (T) replacement therapy in patients with late onset hypogonadism is still conflicting. Several available preparations have been developed to restore either fertility and normal testosterone (T) levels (secondary hypogonadism) or just T levels (primary hypogonadism). AREAS COVERED: Advantages and limitations related to available new treatments will be discussed in detail. In addition, possible news related to preparations in the pipeline will be discussed. EXPERT OPINION: The selection of a specific T preparation should be adequately discussed with each subject. Transdermal T preparations are those that can preserve, after a unique morning administration, the circadian rhythmicity of T secretion. Conversely, short-acting preparations (such as oral or intranasal) need two- or three-times daily administration, potentially reducing patient compliance. Long acting T preparations, such as injectable T undecanoate have the advantage of bimestrial or trimestral administration, reducing the required number of administrations. The use of non-steroidal selective androgen receptor modulators (SARM), a heterogeneous class of compounds selectively acting on androgen receptor targets, remains investigational due to the lack of the full spectrum of T's action and the possible risk of side effects, despite their potential use in the treatment of muscle wasting and osteoporosis.
