The contraceptive potential of Acacia nilotica pods and Albizzia lebbeck stem bark methanolic extracts were evaluated in male rodent pests. Ninety (90) multimammate rats (M. natalensis) were randomized into a 3 × 3 factorial design for treatment groups (control, A. lebbeck and A. nilotica) (n = 10) and treatment durations (15, 30, or 60 days). Control rats consumed plain feed. Treated rats consumed feed with 2% w/w of either of the plant extract. Following treatment, male rats were mated to untreated females before they were sedated in ether and humanely sacrificed.
