Abstract

A differential effect of 915 MHz microwave radiation with 500 Hz amplitude modulation of 1 ms pulses on the morphofunctional state of mouse 8-cell embryos has been shown. Then development is not disturbed by irradiation for 15 to 20 min. This effect is suggested to correlate with some changes in the properties of cell membranes as a result of possible local increases of temperature.
