  1. The same 11 males were analyzed in each experimental group (600×g, 3000×g, and 6000×g for 10 min at room temperature) at 0 h and 2 h post-incubation at 37 °C. Different lowercase superscripts letters (a, b, c) indicate significant differences (P ≤ 0.05) for each parameter and assessment point among the centrifugal forces
