摘要:

目的:探讨宫腔菌群分布与不孕症患者冻融胚胎移植结局的相关性。方法:选取20241月至12月在我院行冻融胚胎移植治疗的不孕症患者60例,其中32例发生临床妊娠(妊娠组),28例未发生临床妊娠(未妊娠组)。分析两组患者临床一般资料、宫腔微生物菌群差异。结果:妊娠组和未妊娠组患者年龄、体质量指数、不孕症类型等临床一般资料差异无统计学意义(P>0.05);菌群分析显示:妊娠组特有运算分类单元(OTU780个,未妊娠组特有OTU 1355个,两组共有OTU 987个;妊娠组和未妊娠组宫腔微生物菌群Shannon指数、Simpson指数、Sobs指数、Ace指数和Chao指数差异均无统计学意义(P>0.05);菌群结构差异也无统计学意义(P>0.05);在菌属丰度方面,妊娠组宫腔微生物菌群乳酸杆菌、无色杆菌、丛毛单胞菌丰度占比分别为3.30%2.844.55)、6.70%4.488.20)和0.22%0.180.40),均高于未妊娠组(P<0.05),而栖水菌、嗜冷杆菌丰度占比分别为0.87%0.321.22)和0.05%00.12),均低于未妊娠组(P<0.05)。结论:冻融胚胎移植不同结局患者宫腔微生物菌群的组成及结构基本相似,但在菌属丰度上存在差异;宫腔微生物菌群组成和结构可能对妊娠结局的影响有限。

Abstract:

Objective: To explore the correlation between the distribution of uterine microbiota and the outcome of frozen-thawed embryo transfer in infertile patients.Methods: 60 infertile patients who underwent frozen-thawed embryo transfer treatment in our hospital from January to December 2024 were selected including 32 cases with clinical pregnancy pregnanty group and 28 cases without clinical pregnancy non pregnanty group. The differences in clinical general information and uterine microbiota between two groups of patients were analyzed.Results: There was no statistically significant difference in clinical general data such as age body mass index and infertility type between the pregnant group and the non pregnant group P>0.05. Microbial analysis showed that there were 780 operational taxonomic units OTUs unique to the pregnant group 1355 OTUs unique to the non pregnant group and 987 OTUs shared by the two groups. There was no statistically significant difference in Shannon index Simpson index Sobs index Ace index and Chao index of uterine microbiota between the pregnant group and the non pregnant group P>0.05. There was no statistically significant difference in microbial community structure P>0.05. In terms of bacterial abundance the pregnant group had a microbiota of lactobacillus 3.30% 2.84 4.55), achromobacter 6.70% 4.48 8.20), and comamonas 0.22% 0.18 0.40 in the uterine cavity respectively which were higher than those in the non pregnant group P<0.05. However the abundance of aquatic bacteria and psychrophilic bacteria was 0.87% 0.32 1.22 and 0.05% 0 0.12), respectively which were lower than those in the non pregnant group P<0.05.Conclusion: The composition and structure of the uterine microbiota in patients with different outcomes of frozen-thawed embryo transfer are basically similar but there are differences in the abundance of bacterial genera. The impact of uterine microbiota on pregnancy outcomes may be limited.
