Abstract: In this study, microfluidic approaches and fluorescence microscopy were used to study cross-sectional distribution of bull spermatozoa in a rectangular microchannel. The results indicate a strong corner accumulation behavior of bull spermatozoa in a rectangular microchannel. Results indicate that 74% of spermatozoa accumulate near boundaries and only 26% of spermatozoa are bulk swimmers. Furthermore, 66% of wall swimmers are corner swimmers. The distinction and quantification of wall vs. corner vs. bulk swimmers was enabled by the unique head-on microchannel imaging approach applied here.
