The aim of the present study is to evaluate the effect of hydroalcoholic extract of stem bark of Ailanthus excelsa Roxb (Simaroubaceae) (HEA) has been studied in rats to explore its antifertility activity. A strong antiimplantation (72%) and abortifacient activity (56%) was observed at the tested dose levels (200 and 400mg/kg, p.o.). The extract shows further more, significant (P<0.05) increase in uterine weight in immature ovariectomised rats. Simultaneous administration of extract with ethinyl estradiol cause significant antiestrogenic activity. All these observations suggest that hydroalcoholic extract of Ailanthus excelsa has antifertility effect.
