Placental weights and birth weights (SD) of control, fresh embryo transfer (FRESH) and frozen embryo transfer (FET) derived newborns. a The placental weights differ significantly between the groups (P = 0.04, Two-Way ANOVA). FET-derived placentas are heavier compared to FRESH (P = 0.001, Bonferroni pos hoc) and FRES-derived lighter compared to controls (P = 0.01, Bonferroni post hoc). b There are no significant differences in birth weights between the groups. Bonferroni post hoc test for Two-Way ANOVA. Bonferroni post hoc test for two-way ANOVA: *P < 0.05, **P < 0.01, ***P ≤ 0.001
