These conditions share underlying causes, particularly endothelial dysfunction, atherosclerosis, and chronic pelvic ischemia (CPI). This study investigated the therapeutic potential of LDD175, a large-conductance Ca2+-activated K+ channel (BKCa channel) opener, in simultaneously treating both conditions using a CPI animal model of male Sprague Dawley rats. Our study investigated the induction of CPI through surgical endothelial damage combined with a high-cholesterol diet. We assessed erectile and voiding functions by measuring intracavernosal pressure (ICP) and intraurethral pressure (IUP), respectively, after nerve stimulation. We performed histological examinations of vascular changes and western blot analyses of cavernous and prostate tissues to understand the underlying mechanisms. This study evaluated the effectiveness of LDD175 compared to standard treatments, such as sildenafil for ED and tamsulosin for LUTS. Therefore, the CPI model successfully demonstrated ED and LUTS symptoms with decreased ICP and increased IUP. Analysis revealed elevated levels of hypoxia-inducible factor-1α, transforming growth factor-β1 and β2 in cavernous tissue, and increased α1A-adrenoceptor expression in prostate tissue. LDD175 administration showed promising results, with dose-dependent improvements in ICP and IUP, and therapeutic effects comparable to those of established treatments. Our findings suggest a novel therapeutic approach that can simultaneously address ED and LUTS, opening new possibilities for clinical application in the treatment of these interconnected conditions.</p>","PeriodicalId":93889,"journal":{"name":"Asian journal of andrology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Primary end point was EF recovery defined as International Index of Erectile Function-5 (IIEF-5) ≥21 with or without rehabilitation aids. IIEF-5 and prescribed treatments were prospectively collected at 3 months, 6 months, 9 months, 12 months, and 24 months. Among 570 eligible patients, 397 (69.6%) underwent rehabilitation.

Two-year EF recovery rates in patients undergoing andro-rehabilitation ranged from 75% (preoperative IIEF-5 >16) to 45% (preoperative IIEF-5 <16) with rehabilitation aids.

The pathogenicity of these variants was assessed using real-time quantitative polymerase chain reaction (RT-qPCR) and immunoblotting, which revealed a significant reduction in HFM1 mRNA and protein levels in spermatozoa compared to those in a healthy control. Transmission electron microscopy revealed morphological abnormalities in sperm cells, including defects in the head and flagellum.
