We used 80 female rats were randomly selected according to the inclusion criteria, and divided into 2 groups, each consisting of 5 subgroups of 8 male rats and female rats for pairing (1 male: 2 females). Group 1: 40 rats to evaluate the contraceptive effect of the extract of Desmodium molliculum a 100mg/ml solution orally at 200mg/kg, 600mg/kg and 1000mg/kg. Two groups as saline controls and 15mg/kg dose medroxyprogesterone.
