Fig. 2. Effects of pH on percentage of motile spermatozoa and VAP after 1 and 5 min after activation. Effects of pH on percentage of motile spermatozoa and VAP after 1 and 5 min after activation. Motile spermatozoa (A, P=0.000), VAP (B, P=0.000); VAP, Velocity of the Average Path. Different letters refer to significantly different results (mean±s.e.m.; lower case letters, 1 min after sperm activation; upper case letters, 5 min after sperm activation; n=5 oysters). Data were compared using one-way ANOVA and Fisher a posteriori test. Myrina Boulais et al. Biology Open 2018;7:bio031427 © 2018. Published by The Company of Biologists Ltd
