Annotated Dataset Limitations
Building standardized, high-quality annotated datasets is a significant challenge due to reliance on conventional assessment methods, subjectivity, data loss, and image complexities like intertwined sperm or partial structures. This limits DL algorithm performance.

DL for Enhanced Accuracy
Deep Learning (DL) offers significant advantages by processing raw images without extensive preprocessing and achieving higher accuracy. DL models like CNN, DNN, and D-CNN show improved segmentation and classification over ML, particularly with datasets like HuSHeM and SCIAN.
94% True positive rate for sperm head morphology classification with D-CNN (Riordon et al.).Case Study: Automated Sperm Segmentation with DCNN & SVM
DL models have successfully improved segmentation. For instance, U-Net achieved an 88% IOU and 94% DICE score for semantic segmentation. Ilhan et al. developed an automated segmentation framework using group-sparse signals and ROI techniques.
Challenge/Solution: Perdrix et al. proposed a deep learning framework combining a Deep Convolutional Neural Network (DCNN) for head segmentation with a Support Vector Machine (SVM) for classifying each pixel into nucleus and acrosome regions. This approach yielded Dice Similarity Coefficients of 0.94 for the head, 0.87 for the acrosome, and 0.88 for the nucleus segments.
Outcome: Improved segmentation accuracy for head, acrosome, and nucleus regions, showcasing the potential of hybrid DL-ML approaches.

Remaining DL Challenges
DL still faces challenges: lack of high-quality annotated datasets, varying performance across different training datasets (e.g., HuSHeM, SCIAN, MHSMA), and insufficient practical effectiveness in recognizing different sperm parts (head, neck, tail). Future work needs to expand datasets and refine algorithms for better generalizability.
3 Critical limitations in accurate classification of sperm morphological defects with DL models.Case Study: Improving Generalizability with SwinMobile-AE
To address generalizability issues, new architectures like SwinMobile-AE are being developed to combine different models and suppress noise. Future research should prioritize multi-center collaborations for data collection, combining unlabeled and partially labeled data to expand image datasets.
Challenge/Solution: Mahali MI et al. proposed SwinMobile, a deep learning fusion architecture combining Swin and MobileNetV3 for sperm and impurity classification. They further incorporated an autoencoder (SwinMobile-AE) to suppress automated noise, demonstrating strong classification performance across multiple datasets (SVIA, HuSHeM, SMIDS).
Outcome: Enhanced generalizability and noise suppression, leading to more robust sperm morphology analysis across varied datasets.
