The IUA women were categorized into three subgroups based on the severity of adhesion. All IUA patients underwent HA separation followed by periodic balloon dilation along with hormone replacement therapy (HRT). Frozen embryo transfer was performed post-treatment, and a comparative analysis of the general characteristics and clinical outcomes among the subgroups was conducted. The control group consisted of patients who underwent their first embryo transfer of HRT cycle without any uterine abnormalities, as assessed by the propensity score matching (PSM). The clinical outcomes of IUA group and control group were compared. Multivariate logistic regression analyses were employed to investigate the risk factors associated with live birth.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>\u2460 The endometrial thickness was significantly increased post-operation compared to pre-operation in all three IUA subgroups (all <jats:italic>P &amp;lt;<\/jats:italic>0.001), with the most pronounced change observed in the severe IUA group. After treatment, normal uterine cavity was restored in 218 women (93.16%). \u2461 The overall clinical pregnancy rate was 49.57% (116\/234) and live birth rate was 29.91% (70\/234).

Multivariate logistic regression analyses revealed that age (aOR 0.878, 95% CI 0.817~0.944, <jats:italic>P<\/jats:italic>=0.001) and endometrial thickness after treatment (aOR 1.292, 95% CI 1.046~1.597, <jats:italic>P<\/jats:italic>=0.018) were the two significant risk factors for live birth rate. \u2462 Following the process of matching, a total of 114 patients were successfully enrolled in the control group.
