A study from the Hebrew University of Jerusalem indicates that chronic oral inflammation may impair female fertility by triggering systemic immune responses that adversely affect the ovaries. This research highlights a potential biological connection between oral health and unexplained infertility, which affects approximately one in five couples globally. Led by Prof. Michael Klutstein, the study involved testing female mice with dental implants to simulate oral inflammation. The results showed that only one of four mice with inflammation gave birth to a live pup, while all control mice did. The researchers found increased inflammatory cytokines in the ovaries and oxidative damage to ovarian tissue, leading to reduced egg quality and disrupted follicle development. Klutstein emphasized the need for collaboration between fertility specialists and dentists, suggesting that women seeking fertility treatments should first address any oral health issues. The findings underscore the importance of oral health in overall health, linking chronic oral conditions to various systemic diseases. Future clinical studies are necessary to confirm these findings and explore potential treatments, including anti-inflammatory strategies to enhance fertility outcomes.
