title: Investigating the effect of aqueous extract of Chicorium intybus L. leaves on offspring sex ratio in rat.
abstract: A traditional belief in Iranian culture indicates that parental consumption of chicory leaves (Chicorium intybus L.) affects the gender of newborns. The aim of this study was to investigate the effect of aqueous extract of chicory on offspring sex ratio in rat. All rats in experimental groups 1 and 2 were i.p. injected with either 1.0 or 0.7 g/kg body weight (LD50 = 2.244 g/kg) of an aqueous extract of chicory leaves for 30 days at 72 h intervals. The control rats were injected with distilled water in the same manner. After the 8th injection, blood pH, and Na(+), K(+), Ca(2+) and Mg(2+) serum levels, were measured in all groups. On day 30, all the rats were mated within and between groups. The results revealed that in comparison with the control group, there were significant increases (p < 0.01) in Na(+) and K(+) levels, as well as the sex ratio of male to female offspring (10.23%) in experimental group 1. Therefore, it can be concluded that the administration of chicory leaf extract has a significant effect on the sex ratio of the rat offspring.
