Abstract

Turkey sperm were exposed to 2.45-GHz microwave radiation in a temperature-controlled wave-guide apparatus. Temperature was maintained at either 25 or 40.5 degrees C. The sperm were exposed for 30 min at a specific absorption rate (SAR) of 10 or 50 mW/g. Following irradiation, the sperm were used to inseminate virgin turkey hens artificially. During the 9 weeks following the single insemination, the following were assessed: mean number of eggs, percentage of fertile eggs, rate of decrease in egg fertility, percentage of hatched eggs, and percentage of early and late deaths. These data demonstrate that, for the conditions used in these experiments, microwave radiation has no effect on the fertilizing capacity of turkey sperm.

Main findings

Turkey sperm exposed in vitro to 2.45-GHz microwave radiation for 30 minutes at SAR 10 or 50 mW/g, with temperature maintained at 25 or 40.5°C, showed no effect on fertilizing capacity under the experimental conditions.

Outcomes measured

mean number of eggs
percentage of fertile eggs
rate of decrease in egg fertility
percentage of hatched eggs
percentage of early and late deaths

Limitations

Sample size not reported in abstract.
Only one frequency (2.45 GHz), exposure duration (30 min), and SAR levels (10 and 50 mW/g) were tested.
Findings are limited to the specific temperature-controlled wave-guide conditions used.
