Valproic acid (VPA), an anti-epileptic drug, has been reported to cause male sub/infertility. Together with searching for alternative treatments, the degrees to which testosterone levels and sperm quality are decreased under VPA treatment also n eed to be clarified. This study aimed to investigate the protective effects of Momordica cochinchinensis (MC) aril extract containing antioxidant capacity on adverse reproductive parameters induced with VPA. Rats were divided into 6 groups (control, VPA, 200 mg kg-1 of MC only, 50, 100, 200 mg kg-1 MC+VPA, respectively, n=8 in each). Animals were pretreated with MC extract for 23 days before coadministration with VPA (500 mg kg-1, i.p.) for 10 consecutive days. All reproductive parameters including histology, and expre ssion of androgen receptor (AR), Ki-67, tyrosine phosphorylated proteins, and steroidogenic proteins in testis were examined. The result s show d that MC could prevent all reproductive parameters in VPA-treated rats. Moreover, MC+VPA groups showed significant declining of testicular histopathologies compared to VPA group. It also decreased the malondialdehyde level and changes of the testicular St AR, AR, and tyrosine phosphorylated protein expressions. In conclusion, M. cochinchinensis aril extract can prevent adverse male reproductive parameters and essential testicular proteins damages induced with VPA.
