Abstract

Summary A study was made concerning the effects of 12 cm electromagnetic waves and of infra red irradiations upon the testes of adult albino rats. A single ten-minute exposure to microwaves at a temperature of 35°C as measured in the central areas of the testes caused testicular degeneration in all cases. In some experiments testicular damage resulted from a single exposure at temperatures between 30° and 35°C. Testicular damage was not found in experiments in which infra red irradiation was applied for 10 minutes at 38°C but was observed when applied at a temperature of 40°C and above. The type of degeneration resulting from microwave exposure could not be distinguished from that produced by infra red.

Main findings

A single 10-minute exposure to 12 cm electromagnetic waves (microwaves) producing a measured central testicular temperature of 35°C caused testicular degeneration in all cases; in some experiments damage occurred with temperatures between 30°C and 35°C. Infrared irradiation for 10 minutes at 38°C did not produce damage, but damage was observed at 40°C and above; degeneration from microwave exposure was not distinguishable from that produced by infrared.

Outcomes measured

Testicular degeneration
Testicular damage (temperature-dependent)

Limitations

Sample size not reported in the abstract.
Exposure metrics beyond wavelength and temperature (e.g., power density/SAR) not reported.
Findings appear temperature-dependent; non-thermal effects cannot be assessed from the abstract.
Animal study; generalizability to humans not addressed.
