Oxaliplatin (Ox) is widely used for the treatment of various tumors. Since Ox prevents DNA replication and transcription, it may affect organs with rapid cell divisions such as the testes. Although its use during pregnancy has been reported, no information regarding its effects on the testes of the offspring is not available yet. Thirty-two mice were randomly divided into four groups. The control group (1) was administered intraperitoneally 0.2 ml of saline three times a week for the 21 days of pre-pregnancy, pregnancy and lactation. Experimental groups 2, 3 and 4 received 3 mg/kg of oxaliplatin three times a week for 21 days during pre-pregnancy, pregnancy and lactation, respectively. The left testis was removed from male offspring 30 and 60 days after birth. The volume of the testes, seminiferous tubules and interstitial tissue, the surface area and height of the seminiferous epithelium, as well as the length and diameter of seminiferous tubules, were analyzed by means of stereology. Results showed a decrease in the evaluated parameters in experimental groups, in comparison with the control group. Due to the ameliorating effect of Ox on offspring testes, cautiousness is needed during maternal administration in order to preserve the fertility of male offspring.
