Macleod J, Hotchkiss RS · 1941
This 1941 study examined how elevated body temperature (fever) affects sperm production in men, building on earlier animal research showing that heat exposure damages sperm-producing cells in the testes. The researchers found that fever significantly reduced total sperm counts at various time intervals after the temperature elevation, confirming that heat is directly harmful to male fertility.
Bennett RL, Hines EA, Krusen FH · 1941
This 1941 study examined short-wave diathermy (a medical heating device using radio frequency energy) and its effects on foot skin temperature. The researchers found that while diathermy produces deep tissue heating, it can be harmful for patients with poor blood circulation and should be avoided in cases of arterial insufficiency.

This 1941 study examined how fever affects sperm counts in men, building on animal research showing that elevated testicular temperature damages sperm production. Researchers tracked sperm counts at various intervals after men experienced high body temperatures from fever treatment.

Researchers exposed 24 male university students to 1000 MHz microwave radiation at 10 mW/cm² while they performed memory tasks involving nonsense syllables. The study found no significant differences in learning or recall ability between students exposed to the radiation and those who weren't. This suggests that short-term exposure to this specific frequency and power level doesn't impair verbal memory function.
