Figure 4A. Expression of LHr mRNA in three COC quality grades at 6, 12, 18 and 24 h of maturation. Mean ± standard error (n = 4 replicates). abCOC quality grades with no superscripts in common are different, at least P < 0.05. Figure 4B. Expression of LHr mRNA in three quality grades of COCs washed in heparin-free media at 0 h and 6 h of maturation. Mean ± standard error (n = 4 replicates).
