In the present study, the effect of oral administration of Melia azedarach Linn. (dharek) seed extract on fertility index, uterine weight and various histological and biochemical parameters of uterus were studied in the adult cyclic Wistar rats. Average number of embryos and implantation losses in the pregnant animals treated with dharek seed extract was also studied. The extract was prepared using a flash evaporator at 35 degrees C and dissolved in olive oil to prepare doses on per kg body weight basis. The results indicated a reduction in fertility index and average number of embryos in mated rats treated with the dharek extract. Pre-implantation, post-implantation and total prenatal mortalities were increased in rats treated with dharek seed extract during early (D1-D7) and late (D7-D18) stages of gestation period at doses of 5, 10 and 20 mg kg(-1) body wt day(-1). Histological studies showed a significant reduction in myometrial thickness, uterine gland diameter, luminal diameter of uterine glands and luminal epithelial cell height in rats treated with dharek seed extract at 1mg kg(-1) body wt day(-1) for 18 days. Pits and folds in luminal epithelial, mitotic activity in luminal and glandular epithelial cells of uterus were observed to be absent. Biochemically, a significant increase in protein and glycogen contents was observed. Thus, in conclusion, the application of this plant extract in rodent control programme may help to elevate the socioeconomic status of the society.
