John MacLeod, Robert S. Hotchkiss · 1941
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. The study confirmed that heat exposure significantly reduces male fertility, providing the first human evidence of temperature's impact on sperm production.
Bauer, J., Gutman, G. · 1940
This 1940 study by Julius Bauer examined how diathermy (deep heating therapy using radiofrequency energy) affects male reproductive function and sperm production. The research investigated whether the heat generated by RF energy exposure could damage testicular tissue and impair fertility. This early work helped establish the biological effects of radiofrequency radiation on sensitive reproductive organs.
Bauer, J., Gutman, G. · 1940
This 1940 research by Dr. Bauer examined how diathermy treatments affected male reproductive function. Diathermy uses radiofrequency energy to generate deep tissue heat for therapeutic purposes. The study investigated potential impacts on testicular function and sperm production from this early form of medical RF exposure.
Bauer, J., Gutman, G. · 1940
This 1940 research by Dr. Bauer investigated how diathermy (medical heating using radio frequency energy) affected male reproductive function and sperm production. The study examined whether RF-based heat treatments used in medicine could impact testicular health. This represents some of the earliest documented research into how electromagnetic fields might affect human fertility.
Knaus, H. · 1940
This 1940 research by Knaus examined how temperature affects sperm sensitivity to radiation exposure, focusing on the testicles' thermal response. The study explored the relationship between heat and radiation effects on male reproductive cells. This early work laid groundwork for understanding how environmental factors like electromagnetic fields might interact with thermal stress to affect fertility.
WILLIAM BIERMAN et al. · 1935
This 1935 study by Dr. Bierman examined fever therapy for treating pelvic conditions, likely including infections like gonorrhea. The research explored using artificially induced hyperthermia (elevated body temperature) and diathermy (electromagnetic heating) as therapeutic treatments for various pelvic disorders.
WILLIAM BIERMAN, E. A. HOROWITZ, C. L. LEVENSON · 1935
This 1935 study by Bierman examined using radiofrequency diathermy (RF heating therapy) to treat pelvic infections, particularly those caused by gonococci bacteria. The research explored whether controlled RF heating could effectively treat urethral and bladder infections by raising tissue temperature to levels that would kill harmful bacteria.

Researchers exposed pregnant rats to 2.45 GHz microwave radiation (the same frequency as microwave ovens and WiFi) for 100 minutes daily during critical pregnancy days. They found no significant differences in pregnancy rates, fetal development, or birth defects between exposed and unexposed groups. However, higher power levels proved lethal to adult rats from overheating.

Researchers exposed pregnant rats to low-level microwave radiation and found changes in their blood's iron-binding capacity, specifically affecting transferrin protein levels. This study confirmed earlier Soviet research showing that microwave exposure can alter protein composition in blood and organs at power densities that don't cause heating. The findings suggest microwave radiation may affect how the body transports essential nutrients during pregnancy.

Scientists exposed 236 pregnant mice to 148 MHz radiofrequency radiation for one hour daily throughout pregnancy at power levels similar to wireless devices. The exposed mice produced significantly lighter offspring compared to unexposed controls, though no visible birth defects were observed. This suggests RF radiation during pregnancy may affect fetal development even at relatively low exposure levels.

Researchers exposed pregnant rats to 2450 MHz microwave radiation (500 μW/cm²) for 20 hours daily during pregnancy. The exposed offspring showed seven times higher death rates, delayed eye opening, temperature regulation problems, and lasting behavioral and growth changes into adulthood. The study demonstrates that prenatal microwave exposure can cause significant developmental problems even when no effects are visible at birth.

This technical report examined occupational exposure to electromagnetic fields among workers near power lines and those using video display terminals (VDTs), focusing on potential links to leukemia and reproductive health effects. The research addressed workplace EMF exposure levels and associated health risks in occupational settings. This type of occupational health research helps establish safety guidelines for workers routinely exposed to EMF sources.

French researchers examined internal organ damage in mice and rats exposed to ultra-short radio frequency waves. The study investigated how high-frequency electromagnetic radiation affects vital organs and reproductive systems in laboratory animals. This research contributes to understanding potential biological effects of RF exposure on mammalian tissue.

Researchers exposed rats to strong 60 Hz electric fields (100 kV/m) for up to 30 days to test effects on reproduction and development. The study found no impacts on mating behavior, fertility, fetal development, or sperm quality. This suggests that extremely low frequency electric fields at these levels may not significantly harm reproductive health in mammals.

Researchers exposed pregnant mice to microwave radiation at 2450 MHz (the same frequency as microwave ovens and WiFi) for 3 hours daily during critical brain development periods. They then tested the newborn pups for basic reflexes and neurological development from birth through 21 days old. The study aimed to understand whether low-level prenatal microwave exposure affects behavioral development in offspring.

Researchers tested pollen viability in 12 flowering plant species at four sites with different electromagnetic radiation (EMR) power densities ranging from 1 to 15 μW/cm². They found that higher EMR exposure consistently reduced pollen viability across all plant species and staining methods tested. This suggests EMR can impair plant reproduction by damaging pollen's ability to fertilize.
