{"title":"Variations in diagnostic criteria for male hypogonadism: is there a need for standardizing specialist society guidelines?","authors":"Georgios Tsampoukas, Sourabh Karna, Afonso Morgado, Suks Minhas","doi":"10.1038/s41443-025-01128-0","DOIUrl":"https://doi.org/10.1038/s41443-025-01128-0","url":null,"abstract":"<p><p>Male hypogonadism or testosterone deficiency is characterized by impaired testicular function resulting in reduced androgen production and altered spermatogenesis. The prevalence of late-onset hypogonadism is approximately 2.1% among men aged 40-79 years but it can reach 30% in specific populations. Despite its clinical impact and a market projected to reach $5.1 billion by 2030, there are discrepancies among specialist societies regarding nomenclature, diagnostic cutoffs, and classification. This narrative review discusses the guidance from: the European Association of Urology (EAU), American Urological Association (AUA), Endocrine Society (EnS), Society for Endocrinology (SfE), European Academy of Andrology (EAA), British Society for Sexual Medicine (BSSM), Italian Society of Andrology and Sexual Medicine (SIAMS), Italian Society of Endocrinology (SIE), and the International Society for Sexual Medicine (ISSM). Societies approach the condition differently in terms of nomenclature (Male Hypogonadism vs Testosterone Deficiency), classification, biochemical criteria, and follow-up protocols. Some organizations, including the EAU, SfE, SIAMS & SIE, favour \"male hypogonadism,\" spotlighting diminished testicular function in both testosterone and sperm production. Others, like the AUA, BSSM, and ISSM, prefer \"Testosterone Deficiency,\" emphasizing symptomatic low Testosterone levels. Classifications often distinguish primary from secondary causes, but several guidelines adopt categories such as functional or compensated hypogonadism. Finally, divergent diagnostic cutoffs for total and free testosterone create \"gray zones\" and differing follow-up recommendations-particularly around Prostatic Specific Antigen (PSA) and haematocrit (Hct)-underscore the need for standardization. As these inconsistencies may affect clinical practice and research, consensus-based, collaborative efforts from international expert panels are needed to establish universally accepted guidelines that address the current variability in male hypogonadism.</p>","PeriodicalId":14068,"journal":{"name":"International Journal of Impotence Research","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144667601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It may also induce psychological distress, which can exacerbate physical symptoms, creating a vicious cycle. There is currently no standardised treatment for HFS, and management typically focuses on addressing both the underlying causes and presenting symptoms. A systematic review of the literature identified 8 eligible studies. Although the exact aetiopathogenesis remains unclear, it is hypothesised that an initial penile trauma may trigger a cascade of neurovascular and inflammatory events. The associated psychological impact may further perpetuate symptoms, reinforcing the cycle of dysfunction. Common symptoms include perineal pain, urinary disturbances, and erectile and ejaculatory dysfunction. Evaluation involves a comprehensive clinical history, relevant blood and radiological investigations to exclude other pathologies, and the use of symptom questionnaires. Reported treatments include phosphodiesterase-5 inhibitors, anxiolytics, low-intensity shockwave therapy, pelvic floor physical therapy, spinal surgery, and biopsychosocial therapy. Management should be individualised, with a focus on relieving symptoms and breaking the self-perpetuating cycle of HFS.

Twelve adult patients (mean age 39.1 ± 10.8 years) underwent Himplant^TM insertion between January 2023 and May 2024. Standardized pre- and postoperative measurements showed a mean increase of 3.52 ± 0.41 cm in flaccid dorsal length and 2.78 ± 0.54 cm in midshaft girth (p < 0.0001). A non-validated follow-up questionnaire revealed that 85.7% of respondents (6/7) reported improved self-confidence in both daily life and sexual activity. The overall complication rate was low and limited to minor, conservatively managed issues; there were no penile infections, penile skin erosions, or other cases requiring implant removal. Notably, no recurrences of AABP were observed during a median follow-up period of 16.5 months.
