A, Least squares means of maximum oestradiol concentration for each cycle within type of exposure. Ctrl = control cycle; Trt = treatment cycle. B, Least squares means of the sums of concentrations of oestradiol during the 48 h and 8 h sampling, respectively, for the four experimental cycles. Cycles 1-2 are control cycles and cycles 3-4 are treatment cycles.Back to article page
