Control women without PCOS with unexplained infertility showed higher levels of PCB118, PCB153, PCB138 and PCB180 (p<0.05) compared to those control women without PCOS with tubal or male factor infertility (Figure 3), though other hormonal parameters did not differ between infertility causes, other than FSH that was lower in the unexplained group (p=0.01). Here, BRD2 is linked to Infertility.
