Recurrent miscarriage, poses a significant challenge for many couples globally, the causes of which are not fully understood. Recent studies have shown the intricate link between uterine inflammation and recurrent miscarriages. While inflammation is essential during early pregnancy stages, especially in embryo implantation, an imbalance can lead to miscarriage. Key inflammatory mediators and an imbalance in immune cells can significantly alter and contribute to recurrent miscarriages. Lifestyle factors like smoking and obesity exacerbate inflammatory responses, increasing miscarriage risks. Understanding the interaction between the uterine environment, immune cell imbalances, and recurrent miscarriages is essential for devising effective treatments. This paper presents the latest data on inflammation's role in recurrent miscarriage, emphasizing the significance of diagnosing chronic endometritis and immune imbalances, offering practical recommendations for treatment and diagnosis.
