Benign prostate hyperplasia (BPH) is a progressive disease that is related to age. Known therapeutic agents used in the treatment of BPH are associated with toxicity. Therefore, chemoprevention could be an effective approach. We investigated the ameliorative effects of methyl jasmonate (MeJA) in testosterone propionate (TP)-induced BPH in castrated rats. Castration was performed by removing both testes through the scrotum sack under ketamine anesthesia. Rats were assigned into seven groups of seven animals each: non-castrated control, castrated control, castrated rats that received TP, castrated rats that received TP and MeJA, castrated rats that received TP and finasteride, castrated rats that received MeJA, and castrated rats that received finasteride...
