2. FIGURE 1
Effects of oviductal cell CM on sperm motility. Values are means ± SEM (n = 15). Open circles represent control spermatozoa; closed circles represent cocultured spermatozoa. Comparisons were made between the cocultured and control spermatozoa at the same time points. ∗P<.05. †P<.01. ‡P<.001. §P< Comparisons also were made between the spermatozoa at time 0 and after incubation (control and cocultured) for different periods. ∥P<.05. ¶P<.01. #P<.001. ∗∗P<.0001.
