Eur Urol:男性不育症中肠道、尿液和精液微生物组的功能和分类研究

2021-03-13 AlexYang MedSci原创 发表于上海

泌尿生殖系统和胃肠道微生物群在男性不育症发病机制中的作用知之甚少。

泌尿生殖系统和胃肠道微生物群在男性不育症发病机制中的作用知之甚少。

最近,有研究人员比较了不育和可育男性肠道、精液、胃肠道微生物群的分类学和功能概况

研究人员前瞻性的招募了25名原发性特发性不育的男性和12名有亲子关系的健康男性,并收集了直肠拭子、精液样本、中段尿液标本和实验对照样本。研究人员发现了一个多样化的精液微生物组,且与尿液微生物组有一定的相似性。不育男性的精液α-多样性增加,且β-多样性明显,精液气球菌增加,直肠厌氧菌减少。普雷沃特氏菌的丰度与精子浓度成反比,而假单胞菌与活动精子总数直接相关。输精管切除术似乎能够改变精液微生物组,表明睾丸或附睾存在作用。厌氧菌在患有精索静脉曲张的不育男性的精液中高度超标,但氧化应激和白细胞精子症只与微妙的差异有关。宏基因组学数据发现了S-腺苷-L-蛋氨酸循环的显著改变,其可能通过DNA甲基化、氧化应激和/或多胺合成在不育症的发病机制中发挥多方面的作用

生殖年龄男性精液、尿液和直肠的微生物组

最后,研究人员指出,他们的研究代表了对男性不育症中微生物组的首次全面调查,为未来探索因果关系的调查和基于微生物组的新型诊断和治疗方法提供了基础。
