Cervicovaginal fluid has an important function in the homeostasis and immunity of the lower female genital tract. Analysis of the cervicovaginal fluid proteome may therefore yield important information about the pathogenesis of numerous gynecological pathologies. Additionally, cervicovaginal fluid has great potential as a source of biomarkers for these conditions.This review provides a detailed discussion about the human cervicovaginal proteome and the proteomics studies performed to characterize this biological fluid. Furthermore, infection-correlated pathological conditions of the female genital tract are discussed for which cervicovaginal fluid has been used in order to identify potential biomarkers. Recent years, numerous studies have analyzed cervicovaginal fluid samples utilizing antibody-based technologies, such as ELISA or Western blotting, to identify biomarkers for preterm birth, premature preterm rupture of membranes, bacterial vaginosis and cervical cancer. The present article will discuss the importance of proteomic technologies as alternative techniques to gain additional meaningful information about these conditions. In addition, the review focuses on recent proteomic studies on cervicovaginal fluid samples for the identification of potential biomarkers. We conclude that the use of proteomic technology for analysis of human cervicovaginal fluid samples is promising and may lead to the discovery of new biomarkers which can improve disease prevention and therapy development.

Background: Little is known about the efficacy of preexposure prophylaxis (PrEP) or what biologic factors may influence HIV transmission in transgender men (TGM). In this study, we sought to explore the effect of testosterone on the vaginal microbiome, cervicovaginal fluid (CVF) tenofovir concentrations, and levels of CVF inflammatory markers in TGM on PrEP.
Methods: Cervicovaginal fluid was collected from 13 TGM (7 using testosterone) and 32 cisgender women (CGW) on PrEP.

The presence of high-risk human papillomavirus (HR-HPV) contributes to the development of cervical lesions and cervical cancer. Recent studies suggest that an imbalance in the cervicovaginal microbiota might be a factor in the persistence of HR-HPV infections. In this study, we collected 156 cervicovaginal fluid (CVF) of women with HR-HPV infection, which were divided into three groups (negative for intraepithelial lesions = 78, low/high-grade squamous intraepithelial lesions = 52/26).

Lactobacillus species dominance of the vaginal microbiome is a hallmark of vaginal health. Pathogen displacement of vaginal lactobacilli drives innate immune activation and mucosal barrier disruption, increasing the risks of STI acquisition and, in pregnancy, of preterm birth. We describe differential TLR mediated activation of the proinflammatory transcription factor NF-κB by vaginal pathogens and commensals.

Objective: This study aimed to detect the proteins and metabolites in the cervicovaginal fluid to observe their relationship with the occurrence of placenta accreta spectrum and the potential biomarkers with predictive value.
Methods: Cervicovaginal fluid samples were collected before delivery from 6 participants of PAS and 6 controls subjects with similar gestational ages. The severity of PAS was evaluated by ultrasound and MRI scoring system and confirmed by the intraoperative findings or pathological examination.
