in addition , glycogen phosphorylase activity in the decidual tissue during the early period of gestation ( 4 -- 10 weeks ) was lower than that in the endometrial tissue during the late secretory phase of the cycle , and in particular , the active form ( -amp ) was significantly ( p less than 0.005 ) low , with the result that the glycogen content in the decidua was significantly ( p less than 0.05 ) higher than that in the endometrium .
