The main aim of this research study is to determine the effect of ethanolic fractions of bryophyllum pinnatum leaves on the male testes using adult male wistar rats. Thirty (30) adult male wistar rats were divided into three groups of ten rats each. Group (A) serve as the control group and was administered with distilled water, Group (B) was treated with 100mg/kg/body weight of the bryophyllum pinnatum extract. Group (C) received 200mg/kgbw of the extract. The treatment lasted for a duration of 8weeks. The rats were sacrificed the day after the last dose and the testes were removed and processed for histological studies. The results from the treated groups showed increase intercellular spaces within the seminiferous epithelium, shrunken and increase lumen, suggesting cells disintegration. This is indicative that bryophyllum pinnatum extract may have adverse effect on the testes of the treated rats
