Protection against Cyclosporine-Induced Reprotoxicity by Satureja khuzestanica Essential Oil in Male Rats

Background The effects of cyclosporine (Cs), a fungal cyclic polypeptide with potent immunosuppressive activity, on fertility have assumed greater significance with the increasing numbers of transplantations being performed all over the world. Current study was undertaken to investigate the potential of Satureja khuzestanica Essential Oil (SEO) as an antioxidant to mitigate Cs-induced reprotoxicity. MaterialsAndMethods In this experimental study (April-July 2012), thirty-two adult male Wistar rats were randomly divided into 4 groups of 8 animals each. Two groups of rats were administered Cs [40 mg/kg/day, per oral (p.o.)] for 45 days. One of these groups received SEO (225 mg/kg/day, p.o.) four hours after Cs administration. A vehicle-treated control group and a SEO control group were also included. Epididymal sperm characteristics, in vitro fertilizing capacity as well as embryo development were evaluated. For statistical analysis, one-way ANOVA and Tukey’s post-hoc test were used, and the value of P
