The purpose of this study was to analyze whether FSH and LH hormone treatment directly or indirectly affect embryo development in embryonic development. To determine this, we compared the development of embryonic cells through the expression pattern of MMPs. As a result, 33.8% of blastocysts were formed in FSH added group, 20.8% in LH added group and 10% in FSH + LH added group. In addition, the activity of MMP-9 was highly detected in the FSH-added group, and the expression of Casp-3 was much lower than that of the other groups. These results suggest that the addition of FSH seems to increase the activity of MMP-9 in embryonic cells, and that LH, on the contrary, may activate MMP-2 activity. In addition, the expression level of MMP-2 in the FSH-added group was high in the Trophoblast cell group and in the LH-added group, the hormone ideal secretion might affect the development of the embryonic cell.
