Aim:To study the effect of high power microwave (HPM) radiation on the testicular germ cell apoptosis. Methods: One hundred and twenty-five Spraque-Dawley rats were randomly divided into two groups, the control group and the experimental group and the latter was further divided into four subgroups: 10 mW/cm2 5 min, 10 mW/cm210 min, 20 mw/cm2 5 min and 20 mW/cm210 min. The experimental groups were radiated with S wave band of 10 mW/ cm2,20 mW/cm2 high power microwave for 5 or 10 min. Testicular samples were taken at 6 h, 24 h, 48 h, 72 h and 5 d after radiation. The testicular germ cell apoptosis was detected by in situ terminal deoxynucleotityl transferase mediated dUTP nick end labeling (TUNEL). Results: The number of apoptotic cells of the 6 h, 24 h and 48 h experimental groups after 10 and 20 mW/cm2 radiation for 5 min was significantly larger than that of the controls (P< 0.01), especially after 10 mW/cm2 radiation. The number of the 6 h group reached the peak (161.27±+5.90)/5 convoluted tubules. Th
