Quantification of immunoexpression of AR and HOXA10 in endometrium tissues from non-PCOS and PCOS women. Graphs show quantification of AR and HOXA10 immunoexpression in the proliferative (n = 2) and secretory phase (n = 3) endometrium tissues obtained from non-PCOS women and those before and after 3 months of metformin treatment in women with PCOS (n = 3). The experiments were performed in triplicate for each sample. Different letters above the bars indicate the significant differences at P < 0.05. AR, androgen receptor; HOXA10, homeobox A10; HSCORE, histological score; PCOS, polycystic ovary syndrome
