Thirty six gilts were superovulated, The progesterone content. Progestrerone level significantlycorrelated witb the number of ovulation points(corpus luteum)(r_1=0.4441,P0.01 );there was not statisticallysignificant correlation between progesterone level and the number of colleeted cmbryos(r_2=0. 2296,P0.05);progesterone level was strongly correlative.with the number of three to eight-cell cmbryos(r_3 = 0.6692,P0.01).So,the progesterone content could be,to a greater or lesser exten, consideted a parameter of embryoniestage.
