Women with provoked vestibulodynia (PVD), a common cause of dyspareunia, are typically considered a homogeneous group. However, research suggests that differences on some factors (e.g., medical history, pain characteristics, psychological functioning, treatment response) exist based upon whether the pain was present at first intercourse (primary PVD: PVD1) or developed at some later point (secondary PVD: PVD2). ⋯ The findings from this study support previous research indicating that women with PVD1 and PVD2 differ in a number of domains. Further research is needed to confirm and elaborate on these findings.
