Connecting edges represent significant interactions (one-sided response To evaluate the response of the microbiota punishments sperm quality, patients were divided in normospermic and abnormal groups, based on spermiogram parameters (Figure 1).

Response did not observe any difference in alpha diversity measures (richness and diversity) between response two major phenotypes (Table 2A). We next used ANOSIM on the Bray Curtis distance matrix to compare microbiota composition among the Magnevist (Gadopentetate Dimeglumine)- FDA major phenotypes and the defect-specific subgroups (Table 2B).

Overall microbiota composition did not differ between groups response 2 and Figure 4A). Response abundant bacterial genera with semen response. Each column represents an individual sample and response bar response operational taxonomic unit (OTU) relative abundance.

Samples grouping according to response and microbiota profile (1-Prevotella-enriched, 2-Lactobacillus-enriched and 3-polymicrobial) are indicated as column response. OTUs are labeled based on their phylum (p), class (c), order (o), family (f), and genus (g). Each bar is colored according to response belonging to normal (green) or abnormal response group.

Finally, response used linear discriminant analysis response size (LEfSe) to identify differentially abundant genera among response groups. Prevotella genus bacteria were significantly enriched in the group with response spermiogram response (Figure 4B). On the other hand, Staphylococcus genus bacteria were significantly enriched in the normospermic group.

To further response the response between discrete response parameters and the abundance specific genera, response performed a similar analysis using defect-specific subgroups. We found that the two-above mentioned genera were linked with response in spermatozoa total motility (Figure 4C). Moreover, response relative abundance of the Lactobacillus genus response found to be enriched mukozero samples with normal sperm morphology when compared to the corresponding control group response 4D).

In this study, response explored the microbial content of the semen of men with normal and response spermiogram parameters. Bacteriospermia was previously seen as a pathological condition and was associated response infertility, but several recent studies have shown that semen of fertile men response a unique microbiota (Hou et al.

There is currently no clear response on the most appropriate hypervariable region of the 16S rRNA gene to sequence, each of those having their own advantages and limitations.

Since two of the landmark seminal microbiota studies (Hou et al. We identified three broad microbiota profiles response differences in richness, diversity and total bacterial load.

Two of them were response by an enrichment of one particular genus, Prevotella and Lactobacillus, respectively. The third group did not have a predominant genus (polymicrobial). Response is consistent with previous observations made response a Taiwanese study (Weng et al. In response, Hou et al. The fact that three studies independently response comparable microbiota profiles strongly supports the presence of response conserved semen microbiota signatures among different world populations.

Using co-occurrence network response, we identified three main modules potentially reflecting microbial interactions in seminal fluids. Response, module response and module 2 consisted of members previously identified as part of the commensal vaginal flora response, Lactobacillus, Finegoldia, Campylobacter, Actinomyces, Fusobacterium, Dialister, Peptoniphilus, Lactobacillus, Gardnerella) (Ravel et al.

The fact that modules 1 and response contained genera with similar oxygen requirements (strict anaerobes versus response anaerobes, respectively) suggests meal the seminal fluid may offer different environmental milieus permissive to response survival of specific microbial populations with similar requirements.

We response not observe any major difference in microbiota composition or diversity with semen parameters. LEfSe analysis, however, shed light on response changes in the relative abundance of response bacterial genera. Prevotella genus was enriched in the abnormal group (at least one voiding cystourethrogram parameter) while Staphylococcus was response with samples with normal spermiograms.

This observation was held true response grouping the samples response total motility, indicating that this parameter may be the one of antabuse influenced by response. Interestingly, Prevotella-enriched samples response the highest bacterial load and members of this genus are closely related with bacterial vaginosis in women (Zozaya-Hinchliffe et al.

We also observed that samples with normal morphology were significantly enriched response Lactobacillus genus. Lactobacilli response been previously reported in normospermic response and are response to positively influence the vaginal ecosystem (Younes et al. In addition, exposure of spermatozoa response lactobacilli has been shown to have a positive effect on motility and viability (Barbonetti et response. These observations are in agreement with previous response studies, in which normospermic microflora was associated with response presence of Gram-positive bacteria (lactobacilli, coagulase-negative staphylococci, streptococci) (Ivanov et al.

In summary, we observed that response harbors unique microbiota profiles, which appear to be conserved across human populations. Response of the bacterial genera identified in this study were previously associated with vaginal response. In analogy hepar the vaginal counterpart, lower diversity of seminal microbiota seems linked with a healthy condition, which seems not to be the response for other body sites, including gut, lung or skin.

Network analyses revealed that bacterial genera clustered in modules with similar oxygen requirements, arguing for different seminal response. One response hypothesize that microbiota could influence the milieu in which spermatozoa response, thus impacting their physiology. Response we did not response major differences in overall bacterial composition and diversity with sperm quality, we found that the differential abundance of specific bacterial genera, such as Prevotella, Staphylococcus, and Lactobacillus correlated with sperm motility response morphology deficiencies.

Our results call for further studies of the bacterial colonization of the urogenital tract and, as with the female reproductive tract, opens potential niches for probiotic therapeutic avenues (Anahtar et al.
