title: [Morphological changes in mice sperm head after exposure to radiation and to cyclophosphamide].
abstract: Male mice Sfis:Pzh were exposed to X-rays, cyclophosphamide or combination of both agents. Each of agent was given in low (0.25 Gy, 25 mg/kg bw CP) or high (1.00 Gy, 100 mg/kg bw CP) doses. Germ cells were exposed to agents as spermatogonia. After 35 days sperm abnormalities test was performed. Exposure to one of agents only, did not enhance statistically significant frequency of morphologically abnormal spermatozoa. Combined treatment of spermatogonia to both agents in low as well in high doses induce clear biological effects, but only combination of high doses (1.00 Gy + 100 mg/kg bw CP) induce statistically significant effect. Results obtained in this study confirmed, that ability of different agents to induce sperm-shape abnormalities is related to its ability to induce mutations in germ cells.
