| Abstract | ||||
| 3,4-Methylenedioxymethamphetamine (MDMA or "ecstasy") is consumed mainly by young population. For this reason, it is especially relevant to take into consideration the effects on the reproductive system. The influence of MDMA on the fertility and reproduction of the male rat was assessed in this study. Material and methods: MDMA was administered orally at 0 mg/kg (control), 10 and 30 mg/kg to male rats for 15,30,45 consecutive days followed by 15 days withdrawal. Hormonal, biochemical, histological and testicular were evaluated in the rats. The present study aimed to investigate if daily oral administration of ecstasy at low doses(10mg) for 45 days has any deleterious effects on reproductive functions of male rats. Animals were randomly divided into four groups of ten rats each, assigned as control rats, or(0mg ecstasy), rats treated with 10mg ecstasy for, (15,30,45) days, rats treated with 30mg/kg body weight ecstasy for(,15,30,45)days by oral gavage. The third group(45 days) was followed by 15 withdrawal period(W15). Results: The activities of superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase in testicular homogenate were decreased while the levels of lipid peroxidation increased significantly in the treated rats as compared with the corresponding group of control animals. In group 30mg, only, arachidonic acid was significantly elevated in the testicular homogenate while linoleic acid was decresed when compared to control. Testis DNA fragmentation was observed in 30mg group, but not 10.mg. It is concluded that low doses of ecstasy exposure(10 mg/Kg) had moderate detrimental effects on reproductive organ system and more severe effects are likely to be observed at higher dose levels. These results indicate that ecstasy is directly toxic to primary Leydig cells, and that the decreased percentage of normal cells and the increased level of DNA damage in ecstasy -exposed Leydig cells may be responsible for decreased testosterone secretion. The results suggested that graded doses of ecstasy elicit depletion of antioxidant defence system and induce oxidative stress in testis of rats. In conclusion: the adverse effect of ecstasy on male reproduction may be due to induction of oxidative stress. | ||||
