Disorders of the Male Reproductive System

611
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

概括

肠道微生物群的变化,包括肠道细菌的减少和Ruminococcus gnavus的增加,与勃起功能障碍 (ED) 有关. 这些变化可能会通过动脉样硬化和氨基酸代谢影响ED的发病,这表明潜在的微生物向疗法.

科学领域:

  • 微生物组研究 微生物组研究
  • 人类健康和疾病
  • 代谢途径 代谢途径

背景情况:

  • 人们越来越认识到肠道微生物群对健康和疾病的影响.
  • 肠道微生物群在勃起功能障碍 (ED) 中的特定作用仍然在很大程度上未被探索.
  • 了解这些联系对于推进ED病变研究至关重要.

研究的目的:

  • 调查和比较肠道微生物群组成和代谢途径在男性与健康对照对抗ED.
  • 为了确定与ED相关的潜在微生物生物标志物.
  • 探索肠道微生物群改变对ED病变的贡献.

主要方法:

  • 从19名ED男性和15名健康对照者 (年龄在18-60岁) 收集了便样本.
  • 使用国际勃起功能指数 (IIEF-5) 评估勃起功能.
  • 肠道微生物群的特征是使用NovaSeq PE 150平台上的宏基因组测序.

主要成果:

  • 在ED和对照组之间,没有发现肠道微生物群α多样性或整体组成 (通过PCA) 的显著差异.
  • 特定的细菌物种的丰度发生了变化:Ruminococcus gnavus,Thomasclavelia ramosa,Clostridium spp.和Eubacterium siraeum在ED组中更为丰富.
  • 在ED组中,肠道细菌的丰富度下降,与核酸和脂质代谢相关的途径高度表达.

结论:

  • 这项试点研究在ED患者中发现Bacteroides intestinalis的减少和Ruminococcus gnavus的增加.
  • 这些微生物转移可能通过促进动脉样硬化和影响分支链氨基酸降解来促进ED.
  • 有针对性的肠道微生物群调节为改善ED患者治疗结果提供了潜在的未来治疗策略.
