  1. Measurements of fetuses and placentae from ewes treated with either CO (n = 14) or P4 (n = 10), singleton pregnancies (n = 14) or twin pregnancies (n = 10), and male fetuses (n = 21) or female fetuses (n = 13). Values represent means ± SEM. Different superscripts within Effect columns are significantly different (P < 0.05)
