The objective of this study was to scale-up the procedure for Single Layer Centrifugation SLC through Androcoll

-P, as a preliminary step towords processing the whole ejaculate. The first experiment compared Single Layer Centrifugation using 4.5 mL and 15 mL extended ejaculate SLC-4.5 and SLC-15, resp., assessing sperm quality by objective motility analysis, morphology, viability, and the production of reactive oxygen species ROS. In the second experiment, SLC-4.5 was compared to Single Layer Centrifugation with 25 mL extended ejaculate SLC-25 using motility analysis and morphology. In both experiments, normal morphology and linear motility were significantly higher in the SLC-selected samples than in the uncentrifuged controls 𝑃 < . 0 0 1 , whereas total motility and membrane integrity were unchanged. Although ROS production was higher in the SLC-selected samples than in the controls 𝑃 < . 0 1 , this might have been due to the presence of antioxidants in seminal plasma in the latter. In conclusion, there was no difference in sperm quality between SLC-4.5 and SLC-15 samples, or between SLC-4.5 and SLC-25 samples, indicating that the SLC method can be scaled-up successfully.
