title: Effect of testosterone on the testicular atrophy caused by di(2-ethylhexyl)phthalate (DEHP).
abstract: The involvement of testosterone in di(2-ethylhexyl)phthalate (DEHP) induced testicular injury has been examined by coadministration of testosterone (1 mg/kg) along with DEHP (2000 mg/kg) daily for 15 days. The coadministration of testosterone and DEHP appears to have prevented the testicular injury as judged by the biochemical and histopathological changes. The sperm count and the activity of the testicular enzymes, gamma-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), sorbitol dehydrogenase (SDH), beta-glucuronidase and acid phosphatase, related with the maturation of sperm, which were significantly altered by DEHP treatment were found to be within normal levels after the combination treatment of DEHP and testosterone. The histopathological studies also showed more or less normal spermatogenic events. The results of this study have suggested the involvement of testosterone in DEHP induced testicular atrophy.
