Depressive symptoms were assessed prior to treatment initiation using the Patient Health Questionnaire-9 (PHQ-9). Clinical data related to oocyte retrieval and embryo development were collected after completion of the IVF cycle. Multivariable linear regression models were used to examine the associations between depressive symptoms and reproductive outcomes. Restricted cubic spline (RCS) models were applied to explore dose\u2013response relationships.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The mean age of participants was 30.80 years, and 18.1% met the criteria for moderate or severe depressive symptoms. After adjustment for potential confounders, higher PHQ-9 scores were associated with a reduced number of transferable embryos (\u03b2 = \u22122.17, 95% CI: \u22123.64, \u22120.69), while the association with retrieved oocyte number was of borderline statistical significance (\u03b2 = \u22123.02, 95% CI: \u22126.05, \u22120.002). RCS analyses demonstrated a negative dose\u2013response association between depression severity and IVF-related intermediate reproductive outcomes, with no evidence of nonlinearity (\n
