Supplementary Appendices for Stereological Dynamics of Testicular Development in the Domestic Cat (Felis silvestris catus): Quantitative and Graphical Data

These supplementary appendices provide the complete stereological and morphometric data supporting the manuscript “Stereological dynamics of testicular development in the domestic cat (Felis silvestris catus) and association with DHH signaling: volumetric and cellular patterns.” Appendix A.1 includes graphical representations of age-dependent stereological dynamics of Leydig, Sertoli, and germ cells (Figure A1). Appendix A.2 provides detailed numerical stereological estimators for all analyzed variables across age groups (Table A1). All data are presented as medians ± interquartile range (IQR) and analyzed using nonparametric tests (Kruskal–Wallis with Dunn’s post hoc). These materials ensure transparency and reproducibility of the stereological and morphometric analyses.
