Researchers measured testicular temperatures in 28 volunteers using tissue thermocouples inserted through the scrotal skin. Testicular temperatures were usually lower than rectal temperatures and changed with environmental temperature. Inguinal canals were warmer than the testes in most anesthetized men (average 2.7°F) and warmer than scrotal cavities in all cases (average 3.6°F).

Researchers exposed mouse Leydig (TM3) cells to 1950 MHz RF radiation at a specific absorption rate of 3 W/kg for 24 hours. They measured cell proliferation, cell cycle distribution, apoptosis, reactive oxygen species, testosterone levels, and StAR and P450scc mRNA expression at multiple time points up to 5 days after exposure. After 24 hours of exposure, cell proliferation, testosterone secretion, and P450scc mRNA levels decreased, while apoptosis, ROS, and StAR mRNA levels did not change significantly.

Researchers exposed 13 male guinea pigs to radar radiation from an SCR 517-A unit at 10 cm wavelength and 45 kW peak output for three hours daily over 51 to 83 days. Histological examination of all tissues, including testes, revealed no abnormalities.

Female Sprague-Dawley rats were exposed to 2.45 GHz continuous-wave microwaves at 28 mW/cm² for 100 minutes daily from days 6 to 15 of pregnancy. The study included 67 sham-irradiated and 70 irradiated females, resulting in 64 and 66 pregnancies respectively. No significant differences were found in pregnancy rates, litter size, or the incidence of external, visceral, or skeletal anomalies between the groups. In a separate experiment, 35% of adult rats exposed to 40 mW/cm² died from hyperthermia.

Researchers randomly assigned pregnant rats to six groups and exposed them daily for 15 days to 0, 5, or 25 mW/cm² of 2450 MHz microwave radiation for 10 or 20 minutes. Blood samples were taken before exposure on day 5 and on days 10, 15, and 20 of pregnancy to measure serum iron, unsaturated iron binding capacity, and total iron binding capacity. Total iron binding capacity increased with higher power densities, and significant differences were found between power densities, sampling days, and exposure durations. Rats exposed to 25 mW/cm² for 20 minutes showed a statistically significant increase in total iron binding capacity, while control and low-exposure groups initially dropped.

Researchers conducted eight experiments exposing juvenile and young adult rats and young adult mice to 60-Hz electric fields at 100 kV/m for 30 or 120 days. They measured body and organ weights, food and water consumption, metabolic rates, hormone levels, liver composition, bone growth, and blood chemistry. No reproducible significant differences were found in rats, and mice showed essentially the same parameters between exposed and sham-exposed groups.

Researchers exposed eight pregnant rats to 500 uW/cm² 2450 MHz microwaves for 20 hours a day during the first 19 days of gestation. Exposed litters had seven times more neonatal deaths than controls, and pups weighed less on day 7 and opened their eyes one day later. Prenatally exposed females showed accelerated growth between 40 and 60 days of age and maintained a 10% higher body weight into adulthood.

Researchers exposed eight pregnant rats to 2450-MHz microwaves at 500 μW/cm² for 20 hours daily during the first 19 days of gestation, which reduced the dams' percentage body weight gain compared to sham-exposed controls. During the first week of life, prenatally exposed offspring had a sevenfold higher mortality, lower body weights, and delayed eye opening compared to controls. Exposed female offspring showed accelerated growth after weaning, and as adults they exhibited more avoidance responses in a shuttlebox test and a disrupted colonic temperature rhythm.

Twenty-four Wistar rats were exposed 8 hours daily throughout pregnancy to 2450 MHz microwave radiation at 20 mW/cm². The exposure was non-thermal because rectal temperatures did not rise above control levels. Half of the rats were evaluated for teratologic effects on day 22 of gestation, and the other half raised offspring for postnatal behavioral and physiological testing. No significant alterations in prenatal or postnatal growth and development were observed.

Pregnant ICR mice were exposed to 2450 MHz continuous-wave radiation for 3 hours daily from gestational day 7 to 17 at an average power density of 10 mW/cm². Pups were tested from day 1 to day 21 postpartum using a battery of behavioral and neurological tests, all conducted blind. Exposed pups showed delayed initiation of several behavioral responses compared with sham-exposed pups. The delay affected the time needed for all exposed pups to achieve each response, but all exposed pups eventually reached the same developmental level as controls.
