Link between fertility behavior and edentulous jaw in middle-aged Chinese women: a cross-sectional study from the CHARLS.

Women's health is a critical topic in global public health. Female fertility, an important stage in a woman's life, is closely tied to overall health. Currently, there is a lack of research exploring the relationship between oral health and female fertility.
