Supplementary Appendices for "Quantitative Postnatal Maturation of the Feline Testis from 6 to 36 Months: A Stereological and DHH Immunomorphological Analysis"

These supplementary appendices provide the complete stereological and morphometric data supporting the manuscript “Quantitative Postnatal Maturation of the Feline Testis from 6 to 36 Months: A Stereological and DHH Immunomorphological Analysis” 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. Appendix A.3, which provides the full numerical outputs of the Principal Component Analysis (PCA), including eigenvalues, percentage of explained variance, variable loadings for PC1 and PC2, and individual scores used to generate the PCA score and loading plots presented in Figure 3.
