2. Figure 1
Mean (±SD) osmotic response of human oocytes after exposure to 1.5 M propane-1,2-diol. Oocytes were exposed at 10°C (♦), 24°C (□), and 30°C (■). The solid lines represent the mean predicted osmotic response for each case.

4. Figure 3
Predicted osmotic response of human oocyte exposed to 1.5 M propane-1,2-diol for 10 minutes at 24°C followed by exposure to 1.5 M propane-1,2-diol plus either 0.1 M or 0.2 M (heavy solid line) sucrose at 24°C.

5. Figure 4
Measured osmotic response of human oocyte exposed to 1.5 M propane-1,2-diol plus 0.1 M sucrose at 24°C (□), having been equilibrated previously with 1.5 M propane-1,2-diol. The solid line represents the predicted osmotic response.
