Serum progesterone level correlated with GSD(r=0.521, P<0.001) and with CRL (r=0.407, P<0.001) and FHR (r=0.363, P<0.001).CA-125 level was significantly higher in the group that showed hematoma as compared with the group without hematoma (P<0.001). This evidence concerns the gene MUC16 and hematoma.
