Reactive blue 2 labels protamine in late-haploid spermatids and spermatozoa and can be used for toxicity evaluation

This study shows that Reactive Blue 2 (RB2) specifically stains protamine in late-haploid spermatids and spermatozoa, and can be used to evaluate male reproductive toxicity in mice.

Development of a non-invasive method for testicular toxicity evaluation using a novel compact magnetic resonance imaging system

The paper demonstrates a compact MRI system for non-invasive testicular toxicity evaluation in mice, showing reduced testicular volume and increased signal intensity after busulfan treatment.
