This study aimed to investigate protective effect of Momordica cochinchinensis (MC) aril extract on adverse reproductive parameters of male rat induced with valproic acid (VPA) commonly used in treatment for antiepileptic diseases. Male Wistar rats were divided into 6 groups (control, VPA, 200 mg/kg BW of PE only, and 50, 100, 200 mg/kg BW MC+VPA, respectively). Animals were pretreated with aqueous MC extract for 23 days before co-administered with VPA induction for 10 days. At the end of experiment, all male reproductive parameters and testicular histology were examined. The results showed all doses of PE significantly protect the decrease the weights of epididymis and seminal vesicle but not of body and testicular weights. MC extract also increased sperm concentration and seminiferous tubular diameters in MC+VPA co-administrative groups. Moreover, testicular histology of MC+VPA groups showed significant declining of testicular histopathologies as compared to VPA group. It was concluded that M. Cochinchinensis aril extract can prevent adverse male reproductive parameters and testicular damage induced with VPA.
