This study analysed clustering of syphilis prevalence by administrative division in Kampala and Wakiso districts, using Moran's I tests and Local Indicator of Spatial Association (LISA). We used Kulldorff Spatial-Scan Poisson model to detect syphilis clustering and classified divisions into high- or low-prevalence (HP/LP) syphilis clusters based on 95% statistical significance.

This disease severely affects women's reproductive health and significantly increases the risk of metabolic complications. The pathogenesis of PCOS is complex, involving various pathophysiological mechanisms such as oxidative stress, chronic low-grade inflammation, and insulin resistance. Currently, lifestyle interventions and first-line pharmacological treatments are the primary clinical strategies for managing PCOS. However, existing approaches face numerous limitations in terms of efficacy, safety, and patient compliance, including incomplete therapeutic effects, drug-related side effects, poor adherence, and a lack of long-term safety data, which necessitate further optimization and breakthroughs. Natural compounds have been widely utilized as therapeutic agents worldwide, with some showing potential advantages in preclinical and pharmacological studies, positioning them as potential alternatives to modern drugs. In recent years, astaxanthin, a natural compound, has garnered attention for its auxiliary effects in the treatment of PCOS due to its potent antioxidant and anti-inflammatory properties. Astaxanthin, a strong natural antioxidant derived from Haematococcus pluvialis, exhibits significant antioxidant, anti-inflammatory, anti-proliferative, and anti-apoptotic activities. To systematically evaluate the therapeutic potential of astaxanthin for PCOS, this study conducted a systematic review in strict accordance with the PICOS principles. A comprehensive literature search was performed across PubMed, Web of Science, and Scopus for relevant studies published between January 2020 and March 2026. The retrieved records were screened based on predefined inclusion and exclusion criteria, and the finally included studies were subjected to mechanistic analysis. This review provides a comprehensive analysis of the potential mechanisms by which astaxanthin, as a dietary supplement, improves PCOS through various pathways, including enhancing insulin sensitivity, activating the Nrf2 antioxidant pathway, inhibiting the NF-κB inflammatory signaling pathway, and modulating cellular apoptosis. Furthermore, it delineates the limitations and therapeutic prospects of astaxanthin supplementation, clarifying its significant value in the adjuvant treatment of PCOS and highlighting the key issues that warrant further investigation.</p>","PeriodicalId":73103,"journal":{"name":"Frontiers in reproductive health","volume":"8 ","pages":"1901207"},"PeriodicalIF":3.1,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13402505/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148610289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microdissection testicular sperm extraction (micro-TESE) remains the standard approach for sperm retrieval, yet success rates vary substantially, and many patients undergo surgery without successful sperm recovery. Hormonal optimization using human chorionic gonadotropin (hCG) with or without follicle-stimulating hormone (FSH) has been proposed to improve spermatogenesis in hypogonadal men, but evidence from randomized controlled trials is lacking. This multicenter trial evaluates whether gonadotropin-based hormonal optimization improves sperm availability for intracytoplasmic sperm injection (ICSI) compared with standard-of-care (SOC) management in men with idiopathic NOA and biochemical hypogonadism.</p><p><strong>Methods and analysis: </strong>This multicenter, randomized, controlled, parallel-group superiority trial will allocate participants 1:1 to hormonal therapy or SOC. Eligible participants are men with idiopathic NOA, total testosterone <350 ng/dL on two fasting morning tests, and FSH ≥7.6 IU/L, consistent with APHRODITE Groups 3-4. Key exclusion criteria include cryptorchidism, prior chemotherapy or radiotherapy, defined genetic NOA (e.g., AZFa/complete AZFb deletions), prior micro-TESE, recent hormonal therapy use, uncontrolled endocrine disease, severe liver disease, polycythemia, active malignancy, inability to comply with the study procedures, and clinically significant varicocele. Participants assigned to the intervention arm will receive gonadotropin-based hormonal optimization using hCG and recombinant FSH, with hormonal monitoring and hCG dose titration throughout treatment. The control arm will receive standard management without hormonal therapy. The primary endpoint is a composite treatment-policy outcome defined as sperm availability suitable for ICSI at any time from randomization through Week 16, either through ejaculated sperm or through micro-TESE. Secondary outcomes include micro-TESE sperm retrieval success rate, need for surgery, embryologic outcomes, reproductive outcomes, and treatment safety. The study is designed as a pragmatic comparative effectiveness trial that intends to evaluate whether biologically informed hormonal optimization improves clinically meaningful sperm availability under routine clinical practice conditions.</p><p><strong>Ethics and dissemination: </strong>The study was approved by Institution Ethics Committee (IIVF-UA00l 00).</p><p><strong>Clinical trial registration: </strong>(https://clinicaltrials.gov/study/NCT07540611), identifier NCT07540611.</p>","PeriodicalId":73103,"journal":{"name":"Frontiers in reproductive health","volume":"8 ","pages":"1867412"},"PeriodicalIF":3.1,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13391572/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148581332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
