Integrated subcellular localization of functional fluorescence probes and functional analysis in motile spermatozoa by an AI-enhanced algorithm.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In the evaluation of male infertility, precise assessment of sperm functional competence has surpassed the requirements of conventional semen parameters. Existing computer-aided analysis systems are deficient at the molecular diagnostic level and also face challenges in live-cell fluorescence quantification. To address these issues, we have developed a novel integrated computational-imaging platform that combines a fine-tuned You Only Look Once version 8 (YOLOv8) architecture, tailored for the EVISEN dataset, with dual-probe fluorescence microscopy image segmentation, enabling simultaneous quantification of intracellular pH (pHi) and mitochondrial DNA G-quadruplexes (mtDNA G4s). By automating the localization of fluorescent foci, our algorithm systematically discriminates between the fluorescent signatures of the sperm head and principal piece, revealing correlations between fluorescence intensity ratios and sperm functional outcomes. This study demonstrates the potential of artificial intelligence (AI)-enhanced multimodal sperm analysis for molecular phenotyping of sperm functional competence. Integrating deep learning with live-cell fluorescence imaging, our platform offers a transformative tool for mechanistically informed diagnostics of male infertility.
