Effects of A30 exposure at different gestational ages on abortion rate and fetal survival. a Abortion rate is the ratio of the number of aborted mice to the total number of pregnant mice in a group (n = 10 per group, three independent experiments). b Total live birth rate is the ratio of the surviving embryo to the total embryos of a pregnant mice (n = 10 per group). c Live birth rate in the non-aborted mice is the ratio of the surviving embryos to the total embryos in a non-aborted pregnant mouse (n = 5–10 per group). d The mean of maternal, placental and fetal weights of non-aborted pregnant mice at E16.5 (n = 5–10 per group). e The mean number of fetuses per dam (n = 10 per group). f The mean number of viable fetuses in non-aborted pregnant mice (n = 5–10 per group). Data are shown as mean ± s.d. The symbol ** represents p < 0.01 by ANOVA with Tukey’s test post-hoc
