Background: A number of studies on reproduction have mentioned Origanum Vulgare extract’s ability to reduce mortality rates and improve fertility rates. However, other studies have suggested that it is possible to use Origanum Vulgare extract to induce abortion. The aim of this study was to investigate the effect of different doses of Origanum Vulgare on embryo survival and macroscopic abnormalities in mice.
Methods: In this study, 24 mice Balb/c female weighting approximately 25-30 g were divided into 4 groups. Origanum Vulgare extract was prepared different concentrations (2.5, 12.5, and 25 mg in 0.25 ml distilled water) were administered, by oral gavage, to three experimental groups of mice between day 6 (starting gastrulation) until day 15 of pregnancy (end of organogenesis). The control group consisted of six mice that received 0.25 ml of distilled water daily. On day 16 of study, pregnant mice were anesthetized by chloroform and fetuses were removed and stained with Alcian Blue, Alizarin Red s and microwave irradiation. Morphological and skeletal abnormalities were investigated by light and stereomicroscopes.
Results: The results of this study showed that high doses of the Origanum Vulgare extract significantly decreased the mean number of embryos (100.5, P>0.05), mean number of live embryos (70.5, P>0.05) in each mouse and resulted in significant reduction in mean weight(11848 mg, P>0.05) and crown-rump length(11.90.23 mm, P>0.05) and the overall size of fetuses compared to control group, whereas there was no significant difference between the groups receiving low dose of Origanum Vulgare extract with control group. In addition, under the effect of the Origanum Vulgare extract the subcutaneous bleeding seemed (20.1, P>0.05) significantly more frequent compared to the control group.
Conclusion: Origanum Vulgare extract did not have any positive effect on fetal development and high dosages led to an increased incidence rate of abortion and fetal malformations in the fetuses of women who received it.
