Figure 1. Average percentage of HOXA10 expression in the proliferative phase of the menstrual cycle (8^th to 12^th day) between the groups: fertile without endometritis, infertile without endometritis and infertile with endometritis. This represents a significant difference compared to the control group (fertile without endometritis) (p value<0.05; ANOVA with Tukey’s post hoc test).
