Cadmium (Cd) is a major environmental toxicant and an endocrine disruptor. We investigated the protective effects of methanol extract of Artocarpus altilis (AA) against Cd-induced testicular damage in rats while quercetin (Que) served as standard. The total flavonoids and phenolic contents (TFC and TPC), 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl (OH) radicals scavenging activities of AA were determined. In vivo, thirty male Wistar rats were assigned to six groups and orally treated with corn oil (control), Cd alone, Cd+Que, Cd+AA, Que and AA alone. Que and AA were given at doses of 25 and 200 mg kg−1, respectively, for 3 weeks and challenged with two doses of Cd (1.5 mg kg−1). Results showed that TFC and TPC of AA increased with increase in concentration. AA scavenged DPPH and OH radicals in a dose-dependent manner. Administration of Cd significantly increased the relative weight of testis of rats. Lipid peroxidation was significantly increased while antioxidant parameters decreased in testis of Cd-treated rats. Also, Cd-treated rats had significantly reduced sperm count, motility, sialic acid, luteinising hormone and testosterone relative to controls. Pre-treatment with AA or Que significantly attenuated the biochemical alterations observed in Cd-treated rats. Overall, AA protects against Cd-induced testicular damage via antioxidative mechanism.
