Fig. 2From: Metabolites involved in cellular communication among human cumulus-oocyte-complex and sperm during in vitro fertilizationDifferences in the percentage of acrosome-reacted spermatozoa between SAI, SWI and CS. Error bars indicate SE of the mean (% values). Asterisk denotes P < 0.05 (α-values maintained by sequential Tukey's HSD corrections). NS, not significant differences. SAI: spermatozoa after insemination; SWI: spermatozoa without insemination; CS: control spermatozoaBack to article page
