A new deep learning framework combines EfficientNet-B0 with CBAM to improve accuracy and interpretability in sperm morphology classification. Evaluated on SMIDS and HuSHem datasets, it achieves 90.2% and 93.9% accuracy with macro F1 scores of 0.913 and 0.948, outperforming baseline models. Grad-CAM++ visualizations enable transparent feature analysis, supporting clinical adoption in fertility clinics.
