Conclusion
We found that while some women undergoing salpingectomy for various reasons harbored bacteria within their FT, women with hydrosalpinx generally did not. This implies that even though infection may be the cause of hydrosalpinx, bacteria are not present by the time patients undergo surgery. We also found that women with hydrosalpinx had a more “dysbiotic” vaginal microbiome, and in women without hydrosalpinx, microbial composition within the vagina and fallopian tubes differed both in composition and diversity of bacterial communities, possibly representing two ecological environments. The characteristics of the FT microbiota and its role in the pathogenesis of female reproductive pathologies should be further investigated.
