Abstract
Tubal factor is an important contributor to female infertility, and the current diagnostic approaches cannot correctly identify many subtle causes of tubal dysfunction. While it is known that the most common cause of tubal factor infertility is pelvic inflammatory disease (PID), creating critical alterations of the tubal epithelium, little attention has been devoted to understanding the tubal modifications caused by the resident microbial population and their interaction with the surrounding tubal epithelium. Furthermore, most of these samples are obtained by traumatic procedures such as direct sampling during laparoscopy using a cytobrush. However, as in any other organ of the female genital tract, the microbiota environment of the fallopian tube plays an essential role in maintaining tubal functioning, counteracting the pathogenic effect of acquired microbes. Consequentially, to better analyze the tubal microbiota without causing anatomical and/or functional alteration of the fallopian tube and preserving fertility, the hysteroscopic approach might be the method of choice, guarantying maximal integrity of the uterine cavity and tubal lumen. Here we describe our plan for using atraumatic hysteroscopic sampling methods to investigate the correlation between tubal microbiota and female infertility.
