Figure 3. Sperm motility parameters at different postactivation times (30, 60,
and 90 seconds) on different sperm classes (C-I, C-II, and C-III). Data are
expressed as mean ± SEM and different letters indicate significant differences
between times. MOT, total motility; PM, progressive motility.
4. Discussion
The subjective sperm quality evaluation, widely used in many laboratories
working with male gametes, depends on the skill, perception, and training
of the researcher who evaluates the sperm samples (Kime et al. 2001,
