Fertility

Long term exposure to EMF can decrease the diameter of seminiferous tubules, resulting in a diminished concentration of sperm in semen, i.e. sperm quality (1).
The underwear’s temperature-regulating properties can contribute to increased sperm viability (2).
Increased serum testosterone levels (6).
Increased sperm motility (5).

Longevity

High levels of testosterone can be instrumental in enhancing cognition and memory (3).
EMF causes suppression of Estrogen, an extremely neuroprotective hormone (7,8).
Low testosterone levels are associated with decreased bone mineral density, decreased muscle mass and an increased risk of diseases, such as cardiovascular and liver disease (4,9).
