RESUMO
Menopause is a cardiometabolic transition with many women experiencing weight gain and redistribution of body fat. Hormonal changes may affect also several dimensions of well-being, including sexual function, with a high rate of female sexual dysfunction (FSD), which displays a multifactorial etiology. The most important biological factors range from chronic low-grade inflammation, associated with hypertrophic adipocytes that may translate into endothelial dysfunction and compromised blood flow through the genitourinary system, to insulin resistance and other neuroendocrine mechanisms targeting the sexual response. Psychosocial factors include poor body image, mood disorders, low self-esteem and life satisfaction, as well as partner's health and quality of relationship, and social stigma. Even unhealthy lifestyle, chronic conditions and putative weight-promoting medications may play a role. The aim of the present narrative review is to update and summarize the state of the art on the link between obesity and FSD in postmenopausal women, pointing to the paucity of high-quality studies and the need for further research with validated end points to assess both biomarkers of obesity and FSD. In addition, we provide general information on the diagnosis and treatment of FSD at menopause with a focus on dietary interventions, physical activity, anti-obesity drugs and bariatric surgery.

Background: Cancer, a potentially fatal condition, is one of the leading causes of death worldwide. Among males aged 20 to 35, the most common cancer in healthy individuals is testicular cancer, accounting for 1% to 2% of all cancers in men. Methods: Throughout this review, we have employed a targeted research approach, carefully handpicking the most representative and relevant articles on the subject. Our methodology involved a systematic review of the scientific literature to ensure a comprehensive and accurate overview of the available sources. Results: The onset and spread of testicular cancer are significantly influenced by genetic changes, including mutations in oncogenes, tu-mor suppressor genes, and DNA repair genes. As a result of identifying these specific genetic mutations in cancers, targeted medications have been developed to disrupt the signaling pathways affected by these genetic changes. To improve the diagnosis and treatment of this disease, it is crucial to understand its natural and clinical histories. Conclusions: In order to comprehend cancer better and to discover new biomarkers and therapeutic targets, oncologists are increasingly employing omics methods, such as genomics, transcriptomics, proteomics, and metabolomics. Targeted medications that focus on specific genetic pathways and mutations hold promise for advancing the diagnosis and management of this disease.

Abstract: In the last decade, Prostate Cancer (PCa) has emerged as the second most prevalent and serious medical condition, and is considered one of the leading factors contributing to global mortality rates. Several factors (genetic as well as environmental) contribute to its development and seriousness. Since the disease is usually asymptomatic at early stages, it is typically misdiagnosed or over-diagnosed by the diagnostic procedures currently in use, leading to improper treatment. Effective biomarkers and diagnostic techniques are desperately needed in clinical settings for better management of PCa patients. Studies integrating omics sciences have shown that the accuracy and dependability of diagnostic and prognostic evaluations have increased because of the use of omics data; also, the treatment plans using omics can be facilitated by personalized medicine. The present review emphasizes innovative multi-omics methodologies, encompassing proteomics, genomics, microbiomics, metabolomics, and transcriptomics, with the aim of comprehending the molecular alterations that trigger and contribute to PCa. The review shows how early genomic and transcriptomic research has made it possible to identify PCa-related genes that are controlled by tumor-relevant signaling pathways. Proteomic and metabolomic analyses have recently been integrated, advancing our understanding of the complex mechanisms at play, the multiple levels of regulation, and how they interact. By applying the omics approach, new vulnerabilities may be discovered, and customized treatments with improved efficacy will soon be accessible.

CONTEXT: Prevalence of obesity in childhood has increased over the past few decades. The impact of obesity and of obesity-related metabolic disorders on testicular growth is unknown. OBJECTIVE: To evaluate the impact of obesity, hyperinsulinemia, and insulin resistance on testicular volume (TV) in pre-pubertal (<9 years), peri-pubertal (9-14 years), and post-pubertal (14-16 years) periods. METHODS: We collected data on TV, age, standard deviation score (SDS) of the body mass index (BMI), insulin, and fasting glycemia in 268 children and adolescents followed-up for weight control. RESULTS: Peri-pubertal boys with normal weight had a significantly higher TV compared to those with overweight or obesity. No difference was found in the other age ranges when data were grouped according to BMI. Pre- and post-pubertal children/adolescents with normal insulin levels had significantly higher TV compared to those with hyperinsulinemia. Peri-pubertal boys with hyperinsulinemia had significantly higher TV compared to those with normal insulin levels. Post-pubertal adolescents with insulin resistance had lower TV and peri-pubertal boys had higher TV compared to those without insulin resistance. No difference was found in pre-puberty. CONCLUSIONS: Closer control of the body weight and the associated metabolic alterations in childhood and adolescence may maintain testicular function later in life.

PURPOSE: To study sexual function and distress in women with functional hypothalamic amenorrhea (FHA) compared to women with FHA and an underlying polycystic ovary syndrome (PCOS)-phenotype, considering also their psychometric variables. As a secondary aim, we explored the relationship between sexual functioning and hormonal milieu in these women. METHODS: This is a retrospective cross-sectional study conducted on 36 women with typical FHA and 43 women with FHA + PCOS-phenotype. The following validated psychometric questionnaires were administered: Female Sexual Functional Index (FSFI), Female Sexual Distress Scale-Revised (FSDS-R), Body Attitude Test (BAT), Bulimia Investigation Test (BITE), State Anxiety Inventory (STAI), Beck Depression Inventory (BDI), Multidimensional Perfectionism Scale (MPS). Available hormones to formulate FHA diagnosis in the standard routine were considered. RESULTS: Women with typical FHA reported a significantly lower FSFI total score than women with FHA + PCOS-phenotype (95% CI for median 16-21.3 vs. 21.1-24.1, p = 0.002), whereas the FSDS-R score was similar in the two groups (95% CI for median 6-16 vs. 6-16.3). No statistically significant differences were evident in body attitude, state and trait anxiety, depression, bulimic risk, and perfectionism between the two groups, confirming the two FHA groups were superimposable from a psychometric perspective. State anxiety correlated negatively with the FSFI total score in both typical FHA (rho: - 0.33, p = 0.05) and FHA + PCOS-phenotype (rho: - 0.40, p = 0.009). In the entire study population, a positive correlation was found between luteinizing hormone, androstenedione, and 17ß-estradiol and the total FSFI score (rho: 0.28, p = 0.01; rho: 0.27, p = 0.01, rho: 0.27, p = 0.01, respectively). CONCLUSION: Women with FHA showed a very high rate of sexual symptoms as part of their condition, but those with a typical diagnosis displayed a more severe sexual impairment as compared with the FHA + PCOS-phenotype, in spite of a similar psychometric profile. Sexual distress was equally present in both groups (approximately 4 out of 10 women). Further studies should be designed to investigate the potential role of sex hormones, mainly LH-driven androstenedione, in influencing women's sexual functioning.

BACKGROUND: P450 oxidoreductase (POR) deficiency (PORD) is characterized by congenital adrenal hyperplasia (CAH) and disorders of sex development (DSD) in both sexes. PORD can also associate with skeletal defects. However, the prevalence of these phenotypes is unknown. AIM: To evaluate the prevalence of CAH, DSD, and infertility of patients with POR gene pathogenic variants by a systematic review of the literature. METHODS: The literature search was performed through PubMed, MEDLINE, Cochrane, Academic One Files, Google Scholar, and Scopus databases. All studies reporting information on CAH, DSD, testicular adrenal rest tumor (TARTs), and fertility in patients with POR gene pathogenic variants were included. Finally, the prevalence of abnormal phenotypes was calculated. RESULTS: Of the 246 articles initially retrieved, only 48 were included for a total of 119 (46 males and 73 females) patients with PORD. We also included the case of a male patient who consulted us for CAH and TARTs but without DSD. This patient, found to be a carrier of combined heterozygous POR mutation, reached fatherhood spontaneously. All the patients found had CAH. The presence of DSD was found in 65.2%, 82.1%, and 82.1% of patients with compound heterozygosity, homozygosity, or monoallelic heterozygous variants, respectively. The prevalence was significantly higher in females than in males. The prevalence of TARTs in patients with PORD is 2.7%. Only 5 women with PORD became pregnant after assisted reproductive techniques and delivered a healthy baby. Except for the recently reported proband, no other studies focused on male infertility in patients with POR gene variants. CONCLUSION: This systematic review of the literature reports the prevalence of CAH, DSD, and TARTs in patients with PORD. The unknown prevalence of POR gene pathogenetic variants and the paucity of studies investigating fertility do not allow us to establish whether PORD is associated with infertility. Further studies on both women and men are needed to clarify this relationship.

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.

PURPOSE: Infertility affects 15-20% of couples and male factors are present in about half of the cases. For many aspects related to the diagnostic and therapeutic approach of male factor infertility, there is no general consensus, and the clinical approach is not uniform. METHODS: In the present document by the Italian Society of Andrology and Sexual Medicine (SIAMS), endorsed by the Italian Society of Embryology, Reproduction, and Research (SIERR), we propose evidence-based recommendations for the diagnosis, treatment, and management of male factor infertility to improve patient and couple care. RESULTS: Components of the initial evaluation should include at minimum medical history, physical examination, and semen analysis. Semen microbiological examination, endocrine assessment, and imaging are suggested in most men and recommended when specific risk factors for infertility exist or first-step analyses showed abnormalities. Full examination including genetic tests, testicular cytology/histology, or additional tests on sperm is clinically oriented and based on the results of previous investigations. For treatment purposes, the identification of the specific cause and the pathogenetic mechanism is advisable. At least, distinguishing pre-testicular, testicular, and post-testicular forms is essential. Treatment should be couple-oriented, including lifestyle modifications, etiologic therapies, empirical treatments, and ART on the basis of best evidence and with a gradual approach. CONCLUSION: These Guidelines are based on two principal aspects: they are couple-oriented and place high value in assessing, preventing, and treating risk factors for infertility. These Guidelines also highlighted that male infertility and in particular testicular function might be a mirror of general health of a man.

OBJECTIVE: The leiomyoma is a benign mesenchymal tumor originating from smooth muscle cells therefore its location is ubiquitous. The genitourinary system is not a common site and the glans localization in pediatric age has been described only three times in the literature to date. CASE REPORT: We describe a case of an 11-year-old boy who presented with a painless, non-bleeding or itchy tumor of the glans. The surgical procedure consisted in the total removal of the mass. The histological study showed spindle cells with an eosinophilic cytoplasm while the immunohistochemical studies proved cells stained strongly positive for smooth muscle actin. The clinical follow-up for more than 5 years after surgery demonstrates the absence of recurrence and discomfort for the patient and a good aesthetic appearance of the glans. RESULTS: Leiomyoma is a benign tumor that can originate anywhere there is smooth muscle. However, localization at the level of the glans can be treated with a total excision due to the presence of a cleavage plane with the surrounding tissues that allows a good reconstruction of the glans itself. CONCLUSIONS: We propose that leiomyoma ought to be considered in the differential diagnosis of any glans mass in children.

OBJECTIVE: Inositol is a carbocyclic sugar polyalcohol. By epimerization of its hydroxyl groups, nine possible stereoisomers can be generated, two of major physiological and clinical relevance: myo-inositol and D-chiro-inositol. Myo-inositol and D-chiro-inositol are normally stored in kidney, brain and liver and are necessary for functions, such as signal transduction, metabolic flux, insulin signaling, regulation of ion-channel permeability, stress response and embryo development. In this narrative review, we summarize the mechanisms by which myo-inositol and D-chiro-inositol can be synthesized and absorbed and their possible role in the etiopathogenesis of neural tube defects. MATERIALS AND METHODS: We performed an online search in the PubMed database using the following keywords: "inositol", "D-chiro-inositol", "myo-inositol", "neural tube defects and inositol". RESULTS: Inositol requirements are partly met by dietary intake, while the rest is synthesized endogenously. Inositol deficiency may be involved in the pathogenesis of diseases, such as metabolic syndrome, spina bifida (a neural tube defect), polycystic ovary syndrome and diabetes. Supplementation of the two inositol stereoisomers, D-chiro-inositol and myo-inositol is important to prevent these conditions. CONCLUSIONS: Inositol is fundamental for signal transduction in the brain, kidneys, reproductive organs and other tissues in response to neurotransmitters, hormones and growth factors. Various genes are involved in inositol metabolism and associated pathways. Altered inositol concentrations are observed in several diseases. Analysis of the genes involved in inositol metabolism may provide important information for the clinical management of these conditions.

Preliminary clinical evidence suggests that metformin has TSH lowering effects in patients with T2DM and hypothyroidism or in those with TSH serum levels in the upper normal value. Also, metformin may exert a protective role against thyroid nodules growth in patients without insulin-resistance. The cross-talk between tyrosine kinase receptors and the G protein-coupled receptors (which the TSHR belongs to) has been already shown and IRS1 may represent the hub link between TSHR and IR pathways. By influencing IRS1 phosphorylation pattern, metformin may sensitize TSHR to TSH, thus explaining the findings of clinical studies. However, the existence of this molecular pathway must be confirmed through proper studies and further prospective randomized placebo-controlled studies are needed to confirm this hypothesis.

BACKGROUND: No data are currently available on the implication of amicrobial leukocytospermia in male adolescents. Therefore, the primary aim of this study was to evaluate the prevalence of amicrobial leukocytospermia among non-smoker late adolescents who were exposed to other risky lifestyles for the andrological health. The main andrological clinical features of adolescents with leukocytospermia were also reported. METHODS: This is a cross-sectional study carried out in 80 boys. Each adolescent underwent a physical examination, and to the assessment of sperm conventional parameters, seminal leukocytes concentration and immature germ cell evaluation. A possible correlation between seminal leukocytes and immature germ cells and testicular volume (TV) was tested. RESULTS: The adolescents enrolled in this study had 18.0 ± 0.4 (range 18.1-18.9) years. Unprotected sexual intercourse was referred by 38% of them. Sexual dysfunctions were found in 25% and isolated hypoactive sexual desire in 12.5% of boys. Low TV and penile length in flaccidity were found in 44% and 30% of them, respectively. Only 41% had normozoospermia at the sperm analysis, whereas 19% had isolated oligozoospermia, 15% oligo-asthenozoospermia, and 25% oligo-astheno-teratozoospermia. Leukocytospermia occurred in 25% (20 out of 80) of adolescents. No seminal infection was detected in 19% (15 out of 80) of them. Adolescents with leukocytospermia had lower progressive sperm motility, percentage of normal forms, TV, and a higher percentage of immature germ cells compared to those without leukocytospermia. Semen leukocyte concentration correlated negatively with TV and positively with the percentage of immature germ cells in the ejaculate. CONCLUSION: Leukocytospermia, increased immature germ cell number, and low TV identify a distinct phenotype suggestive of testicular tubulopathy. Primary prevention of male infertility and the counselling for andrological risky lifestyles is mandatory and should be started as early as possible.

BACKGROUND: Scrotal color Doppler ultrasound (CDUS) still suffers from lack of standardization. Hence, the European Academy of Andrology (EAA) has promoted a multicenter study to assess the CDUS characteristics of healthy fertile men (HFM) to obtain normative parameters. OBJECTIVES: To report and discuss the scrotal organs CDUS reference ranges and characteristics in HFM and their associations with clinical, seminal, and biochemical parameters. METHODS: A cohort of 248 HFM (35.3 ± 5.9years) was studied, evaluating, on the same day, clinical, biochemical, seminal, and scrotal CDUS following Standard Operating Procedures. RESULTS: The CDUS reference range and characteristics of the scrotal organs of HFM are reported here. CDUS showed a higher accuracy than physical examination in detecting scrotal abnormalities. Prader orchidometer (PO)- and US-measured testicular volume (TV) were closely related. The US-assessed TV with the ellipsoid formula showed the best correlation with the PO-TV. The mean TV of HFM was ~ 17 ml. The lowest reference limit for right and left testis was 12 and 11 ml, thresholds defining testicular hypotrophy. The highest reference limit for epididymal head, tail, and vas deferens was 12, 6, and 4.5 mm, respectively. Mean TV was associated positively with sperm concentration and total count and negatively with gonadotropins levels and pulse pressure. Subjects with testicular inhomogeneity or calcifications showed lower sperm vitality and concentration, respectively, than the rest of the sample. Sperm normal morphology and progressive motility were positively associated with epididymal head size/vascularization and vas deferens size, respectively. Increased epididymis and vas deferens sizes were associated with MAR test positivity. Decreased epididymal tail homogeneity/vascularization were positively associated with waistline, which was negatively associated with intratesticular vascularization. CDUS varicocele was detected in 37.2% of men and was not associated with seminal or hormonal parameters. Scrotal CDUS parameters were not associated with time to pregnancy, number of children, history of miscarriage. CONCLUSIONS: The present findings will help in better understanding male infertility pathophysiology, improving its management.

BACKGROUND: The diagnosis of infertility strongly impacts on psychological and sexological couple health. In this regard, some feelings and psychological states were demonstrated in association with reproductive problems. Depression and anxiety are the most common psychopathologies associated with infertility, although also sexuality is strongly involved in infertility conditions. OBJECTIVES: The aim of this study is to develop a tool to probe and assess the emotional aspects, sexuality, and social relationships of the couple seeking medical care for infertility. MATERIALS AND METHODS: A self-reported questionnaire that we will refer to as SEIq (Sexuality and Emotions in Infertility questionnaire) was constructed and developed and, consequently, administered to 162 heterosexual couples (324 subjects) seeking help for reproductive problems. Hence, we performed a specific statistical analysis to assess and validate this new psychometric tool. RESULTS: About 60% of men and women (both partners in 43% of couples) declare that infertility has changed their life (Q10). Moreover, the incidence of sexual disorder declared by the subjects is quite rare in men (10%) but more frequent in women (29%) (p < 0.01). CONCLUSION AND DISCUSSION: The results of this pilot test show that the diagnosis of infertility impacts on the couple relationship affecting the emotional area, interpersonal relationships, and sexual functions of the couples. Moreover, the SEIq appears a valuable tool to coherently probe and relate sexological, psychological, relational, and emotive aspects in partners and couples facing the infertility diagnosis. The explorative factor analysis of SEIq data allows to understand the women, men, and couples' behavior in our sample, individuating a reduced set of factors, prone to an easier evaluation. On the whole, the psychometric evaluation through SEIq might be suitable for the couples during Assisted Reproductive Technologies treatments.

BACKGROUND: Thyroid gland dysfunction represents an epidemiologically relevant disease in the female gender, where treatment with oral contraceptives (OCs) is frequently prescribed. Although OCs are able to impact the thyroid gland function, scanty data have been released on this matter so far. AIM: The aim of this article was to review how hormonal OCs, including estrogen- or progesterone-only containing medications, interact with the hepatic production of thyroid-binding globulin (TBG) and, consequently, their effects on serum levels of thyroxine (T4) and triiodothyronine (T3). We also reviewed the effect of Levo-T4 (LT4) administration in women taking OCs and how they influence the thyroid function in both euthyroid women and in those receiving LT4. REVIEW: The estrogenic component of the pills is capable of increasing various liver proteins, such as TBG, sex hormone-binding protein (SHBG) and coagulation factors. On the other hand, the role of progestogens is to modulate estrogen-dependent effects mainly through their anti-androgenic action. In fact, a reduction in the effects of androgens is useful to keep the thromboembolic and cardiovascular risks low, whereas OCs increase it especially in women with subclinical hypothyroidism or in those treated with LT4. Accordingly, subclinical hypothyroidism is known to be associated with a higher mean platelet volume than normal and this increases cardiovascular risk due to platelet hyperactivity caused by incomplete thrombocytopoietic maturation.

The combined harmful effects of cigarette smoking and hyperglycemia can accelerate vascular damage in patients with diabetes who smoke, as is well known. Can smoking cause diabetes? What are the effects of smoking on macro and microvascular complications? Now growing evidence indicates that regular smokers are at risk of developing incident diabetes. Since the prevalence rates of smoking in patients with diabetes are relatively similar to those of the general population, it is essential to address the main modifiable risk factor of smoking to prevent the onset of diabetes and delay the development of its complications. Quitting smoking shows clear benefits in terms of reducing or slowing the risk of cardiovascular morbidity and mortality in people with diabetes. Does quitting smoking decrease the incidence of diabetes and its progression? What are the effects of quitting smoking on complications? The current evidence does not seem to unequivocally suggest a positive role for quitting in patients with diabetes. Quitting smoking has also been shown to have a negative impact on body weight, glycemic control and subsequent increased risk of new-onset diabetes. Moreover, its role on microvascular complications of the disease is unclear. What are the current smoking cessation treatments, and which ones are better for patients with diabetes? Stopping smoking may be of value for diabetes prevention and management of the disease and its macrovascular and microvascular complications. Unfortunately, achieving long-lasting abstinence is not easy and novel approaches for managing these patients are needed. This narrative review examines the evidence on the impact of smoking and smoking cessation in patients with diabetes and particularly in type 2 diabetes mellitus and its complications. In addition, management options and potential future directions will be discussed.
RESUMO
OBJECTIVE: The aim of this paper is to evaluate the effectiveness of follicle-stimulating hormone (FSH) administration in a cohort of insulin resistant (HOMA>2.5) patients with normogonadotropic idiopathic infertility. PATIENTS AND METHODS: We subdivided patients in two clinical groups basing on the adopted therapeutic scheme: group A (n=44) received 150 units of FSH three times a week for three months (group A); group B (n=35) received 150 units of FSH three times a week for three months and 500 mg of slow-release metformin once a day for three months (group B). We evaluated the post-treatment sperm parameters, sperm parameters normalization rate, spontaneous pregnancy rate, and sperm DNA fragmentation normalization rate. RESULTS: 40% of group A patients and 45% of group B patients became normozoospermic after the treatment, while 30% of group A patients and 32% of group B patients achieved a spontaneous pregnancy. B group patients also obtained higher sperm DNA fragmentation normalization rate (45% vs. 33%, p = 0.03). Compared to group A, group B showed a higher sperm concentration, progressive motility and morphology (p < 0.0001). CONCLUSIONS: The results of this study suggest that the addition of the low-dose slow-release metformin in insulin-resistant patients with normogonadotropic infertility improves the efficacy of FSH therapy.

BACKGROUND: Papillomavirus (HPV) often occurs in the semen of patients with male accessory gland infection (MAGI). Ultrasound (US) evaluation has been suggested as a promising diagnostic tool for patients with HPV-related MAGI. No data on the spontaneous clearance of HPV-DNA have been reported so far in HPV-related MAGI. PURPOSE: The primary aim of the study was to assess the percentage of early HPV-DNA spontaneous clearance in patients with prostatitis. The secondary aim was to evaluate the frequency of spontaneous clearance of HPV-DNA among patients with prostatitis associated with the presence or absence of US abnormalities. METHODS: Patients with inflammatory MAGI and at least one suspicious criterion for HPV infection underwent semen HPV-DNA detection and prostate US. The presence of HPV-DNA was further investigated after a 6-month-long follow-up. MAIN RESULTS: Eighty patients satisfied the inclusion criteria and were recruited in the study. 69% of patients (55/80) showed HPV-DNA persistence in the semen. Among them, 82% (45/55) was positive for US signs of prostatitis, while they occurred only in 12% (3/25) of those patients with no sign of HPV-DNA persistence (p < 0.001). All patients with persistent high-risk HPV genotype (n = 30) showed at least two US signs of prostatitis. In 73% of patients (22/30), E6 and E7 mRNAs were detected. CONCLUSION: US signs of prostatitis more frequently occurred in patients with evidence of HPV-DNA persistence on semen, especially in those with high-risk genotypes. This highlights the importance of US in the framework of HPV-related MAGI.
