The cohort included 7172 semen analyses from 925 adult men paired inflammatory testing. Markers included C\u2010reactive protein (CRP), erythrocyte sedimentation rate (ESR), neutrophil\u2010to\u2010lymphocyte ratio (NLR), platelet\u2010to\u2010lymphocyte ratio (PLR), monocyte\u2010to\u2010eosinophil ratio (MER) and red cell distribution width (RDW)\u2010to\u2010platelet ratio (RPR). Outcomes were total motile sperm count (TMSC), concentration, motility, morphology, and volume. Spearman correlations and Wilcoxon rank\u2010sum tests were calculated across same day and \u00b130\u2010, 60\u2010, 90\u2010, 180\u2010, and 365\u2010day windows.

TMSC showed negative correlations with NLR, PLR, RPR, and MER in shorter windows. Volume and morphology did not exhibit consistent inverse correlations. CRP and ESR lacked consistent negative associations across windows. In odds\u2010ratio analyses, MER predicted lower odds of high concentration at 180 days (OR 0.9945, 95% CI, 0.9893\u20130.9997) and 90 days (OR 0.990, 95% CI, 0.981\u20130.999); PLR predicted lower odds of high motility at 60 days (OR 0.9997, 95% CI, 0.9994\u20130.9999) and 30 days (OR 0.9993, 95% CI, 0.9990\u20130.9995).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Effect sizes were modest but temporally coherent with spermatogenesis, supporting biological plausibility.
