Hoechst 33258 and polyvinylpyrrolidone-40 (PVP-40) were obtained from Shanghai Maokang Biotechnology Co., Ltd. (Shanghai, China). The spermatozoa were washed and incubated with Hoechst 33258 (4 μg ml−1) for 10 min at a proportion of 9:1 to achieve a final concentration of 0.4 μg ml−1 and then centrifuged with 2% (w/v) PVP-40 in PBS. The supernatant was then removed and resuspended in PBS, smeared on clean slides, and fixed for 30 min in 95% (v/v) ethanol after air drying.
