Fig. 3From: Bull spermatozoa selected by thermotaxis exhibit high DNA integrity, specific head morphometry, and improve ICSI outcome Rate of cleavage and blastocyst production. Percentage of cleavage and blastocyst production of the embryos obtained by ICSI using the spermatozoa migrated by thermotaxis (Tx) (n = 8, P < 0.01 for cleavage), not-migrated (NM) by thermotaxis (n = 8), obtained by conventional IVF (n = 6) and oocytes microinjected without sperm (Parthenogenetic) (n = 4). Different letters above error bars (i.e. ±SEM) indicate significant differences (P < 0.001) among groups (Tukey’s posthoc test)Back to article page
