European Urology:不育的已经成为一种流行病了吗?精液微生物组代谢或与不育密切相关

2021-06-06 MedSci原创 MedSci原创

一些患有精索静脉曲张的男性生育能力低下可能是由于微生物群的潜在变化造成的。

全世界5000万不孕夫妇中,约有一半因男性因素而难以受孕。最近的研究表明,随着世界范围内精子数量因不明原因持续下降,这种流行病可能正在扩大。

微生物群是一个术语,描述了居住在人体几乎每个生态位内的所有常驻微生物的独特群落。微生物组群包含诸多遗传物质,在正常的生理共生和致病性失调(细菌对疾病的不适应)中都起着关键作用。尽管微生物组的总体文献越来越多,但探索微生物组在男性不育中的作用的文献却很少。

最近,有研究假设肠道和泌尿生殖微生物群的失调与特发性男性不育有关,利用16S rRNA和shotgun宏基因组学,评估了高分辨率分类和功能代谢谱,并确定了几个可能在男性不育的发病机制中发挥作用的关键异常分类和生化途径。该研究结果发表在European Urology的最新期刊上。

研究小组前瞻性地招募了25名原发性特发性不育男性和12名已被证实为父系的健康男性,并收集了直肠拭子、精液样本、中段尿液样本和实验对照,进行了全面的精液分析,16srRNA以及shotgun宏基因组学测序用于定量高分辨率分类,每个样本的功能代谢途径分析中位数为1.4亿次。

与先前的文献一致,研究者从尿液和精液中鉴定出了丰富的微生物群,并发现男性肠道中的微生物组与尿液及精液中的微生物组明显不同,它们看起来相对相似。假单胞菌、假黄单胞菌和嗜酸杆菌(变形杆菌门的成员)在精液中的表达过多,输精管切除术后,Collinsella(放线菌门)和葡萄球菌(厚壁菌门)的精液都被耗尽。

功能微生物组分析显示不育男性显著的代谢改变

此外,研究还探讨了不育男性和健康生育对照组之间的微生物组的分类差异,并发现了全球多样性的显著差异。研究者在不育男性的精液中发现了增多的空气球菌,且发现普雷沃氏菌和精液质量呈负相关,而假单胞菌和总活跃精子数的直接关联

然而,为什么精索静脉曲张患者中只有一部分人生育能力低下仍存在争议。研究者只在精索静脉曲张的不育男性中发现了厌氧菌的转变。这提出了一个有趣的机制假设,一些患有精索静脉曲张的男性生育能力低下可能是由于微生物群的潜在变化造成的(或者甚至反之亦然)。

总之,这项初步研究代表了对男性不育微生物群的首次全面调查。这些发现也为未来的研究提供了基础。

Cell:中国科学家发现人类Piwi基因突变导致男性不育

中科院生物化学与细胞生物学研究所刘默芳研究组与上海市计划生育科学研究所施惠娟研究组合作研究,首次发现人类Piwi基因突变可导致男性不育,并深入揭示了其致病机理,为相关男性不育症的早期分子诊断及精准医疗提供了理论依据。5月26日凌晨,国际著名学术期刊《细胞》(Cell)在线发表了该项研究成果。据悉,该项研究成果得到了《细胞》编辑部和3位审稿人的高度评价。中科院院士王恩多表示,这项研究工作是一项从人类

Stem Cell Reports:科学家发现特殊的表观遗传标志物 有望治疗癌症及不育等多种人类疾病

近日,一项刊登在国际杂志Stem Cell Reports上的研究报告中,来自马里兰大学的研究人员通过研究发现了一种新型机制,其能指挥种系干细胞或生殖细胞的发育,这种特殊的细胞类型能将遗传信息传递到下一代中,干细胞领域的研究有望帮助研究人员未来有效对抗人类疾病,这项研究中,研究人员发现了能够鉴别雄性生殖细胞的特殊标志物,同时他们还深入阐明了环境因素或表观遗传学因素如何影响这些生殖细胞,这或为开发男

胰激肽原酶在男性不育中的临床应用专家共识(2018版)

生殖系统微循环障碍影响精子质量,改善微循环已经被作为男性不育的基础性治疗方法写入中华医学会男科学分会《中国男科疾病诊断与治疗指南(2016版)》。胰激肽原酶(pancreatic kininogenase)属蛋白水解酶类,具有扩张小血管和毛细血管、增加毛细血管血流量等作用,可改善微循环和器官代谢,其代表药物怡开被广泛应用于改善糖尿病等疾病导致的微循环障碍。在国内、外的男科领域,胰激肽原酶也被用于男

Science:微管蛋白糖基化异常,男性不育的又一个潜在原因!

微管是真核细胞骨架的关键组成部分。有人提出,是微管蛋白翻译后修饰的组合形成的“微管蛋白密码”使微管适应活细胞内的特定功能,但仍缺乏相关机制研究。

Cell Metab:男性不育?从“线粒体”入手有望解决

男性不育可能是由线粒体DNA突变造成的。8月1日,发表在 Cell Metabolism上题为“Increased Total mtDNA Copy Number Cures Male Infertility Despite Unaltered mtDNA Mutation Load”的研究中, 德国Max Planck研究所的科学家证实,增加线粒体中的总DNA数量能够修复不育小鼠的睾丸功能和精子

Curr Biol :高温导致男性不育的原因终于弄清楚了,短暂受热就会诱发精子大量DNA损伤

众所周知,人类的正常体温大约是37℃,而产生精子的最佳温度则低于人体正常体温,在32℃-35℃之间,研究表明,暴露在这一温度范围以上仅仅1℃,就会对男性的生育能力产生不利影响。
