Mouse spermatozoa were exposed in vitro for 1 h to 27‐ or 2,450‐MHz CW RF radiation at SARs of 0 to 90 W/kg under isothermal (37 ± 0.2 °C) conditions. Exposure at either frequency to RF radiation at SARs of 50 W/kg or greater resulted in a statistically significant reduction in the ability of irradiated sperm to fertilize mouse ova in vitro ( P < .05). Over the range of SARs there was no apparent difference in the effects of 27‐ vs. 2,450‐MHz RF radiation. There were no readily detectable exposure effects on spermatozoan morphology, ultrastructure, or capacitation. The reduction of in vitro fertilization is attributed to a direct effect of RF radiation on spermatozoa rather than to heating.
