✦ Synopsis

Mouse spermatozoa were exposed in vitro for 1 h to 27or 2,450-MHz CW RF radiation at SARs of 0 to 90 W/kg under isothermal (37 k0.2 "C) conditions. Exposure at either frequency to RF radiation at SARs of 50 Wikg 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 27vs. 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.
