(d) Offspring gender ratio. (e) Offspring survival rate. (f) Body weight of female offspring from age of 4 to 8 weeks. (g) Body weight of male offspring from age of 4 to 8 weeks. For (a,b), at least eight pregnant females were included. For c, at least 53 newborn pups were counted. For (a–c,f,g), the data are presented as mean ± standard deviation (SD) and differences between groups were evaluated with Tukey’s multiple comparison tests. For (d), the data were evaluated using a chi-square test. For (e) differences between each group were evaluated with log-rank (Mantel-Cox) test. N.S., not significant.
