There was asignificant difference between the groups, with infertile women with endometritishaving lower HOXA11 expression values than women in the controlgroup (fertile without endometritis), as was observed for infertile women withoutendometritis compared to the control group (p value=0.001; fertilewithout endometritis: 212.80±32.99; infertile without endometritis:159.32±36.16; infertile with endometritis: 137.25±55.87). This evidence concerns the gene HOXA11 and Infertility.
