Searching the connection between endometriosis and abortion

This study examined the incidence of abortion among patients with a previous histological diagnosis of endometriosis (N=190) and assessed whether abortion was associated with the extent and anatomic location of endometriosis. Using clinical records, 40 patients (21%) reported a prior abortion, and within this subgroup the authors observed higher representation of mixed endometriosis (ovary and peritoneum) and stage III–IV disease, but these differences were not statistically significant versus those without abortion history (p>0.005). About half of the previously-aborting subgroup reported symptoms, most commonly dysmenorrhea and pelvic pain. The paper’s key limitation is that it relies on retrospective clinical records and finds no significant association despite observed trends, with causality not established. This paper is centrally about endometriosis — it specifically evaluates prior abortion incidence and whether endometriosis phenotype relates to abortion outcomes.
