Figure 3: Influence of CNP on the motility of human sperm (X̄ ± standard deviation, n = 15, *P < 0.05, **P < 0.01, compared with the control group). As shown in the graph, compared with the control, percentage of progressively motile sperm (WHO motility class a + b) was increased at 30 min after CNP was added to the sperm suspension, and the changes were dose-dependent. CNP: C-type natriuretic peptide; WHO: World Health Organization.
