The cyclophosphamide is used in cancer treatment. The aim of this study was evaluating the effect of different doses of this drug on male mice reproductive parameters. The cyclophosphamide was administered in the doses 100, 150, 200 e 250 mg.kg-1, intraperitoneal route, for six weeks. As a result, it was observed a decrease in body mass and a decrease in testicles and kidney's weight, in all animals treated with cyclophosphamide. Only the groups that received the doses 100, 150 mg.kg-1 of cyclophosphamide were able to fertilize their females. There was higher incidence of post- implantation losses, reabsorptions and decrease in fetal viability in the group that received the dose of 150 mg.kg-1. It was observed a reduction in epididymis and liver's weight of the animals treated with the doses 150, 200 e 250 mg.kg-1. Abnormal spermatozoa were found in the doses 200 e 250 mg.kg-1. Based on the methodology used and results obtained, it was concluded that the cyclophosphamide was toxic, considering the decrease in animal's body mass and testicle's weight; promoted hepatotoxicity and nephrotoxic effect; influenced in the animals spermatogenesis taking them to infertility and/or subfertility; decreased fetal viability, despite it didn't cause significant malformations in the offspring.
