What effect does microwave and RF radiation have on human health?

Microwave and radiofrequency (RF) radiation can have significant biological effects, particularly on reproductive health. Research indicates that exposure to these forms of radiation has the potential to lead to reduced spermatogenesis, which is the process of sperm production in men. This reduction can be attributed to thermal and non-thermal effects of RF exposure, leading to alterations in testicular function and decreased fertility.

Additionally, teratogenesis refers to the development of birth defects and can be influenced by various types of electromagnetic radiation, including microwaves and RF. Some studies suggest that exposure during critical periods of fetal development can lead to negative health outcomes. As a result, concerns about reproductive health impacts from chronic exposure to microwave and RF radiation are recognized in the field of industrial hygiene.

The incorrect options refer to effects that are either beneficial or unrelated to the negative health impacts associated with RF and microwave radiation exposure. For instance, improved cardiovascular performance and enhanced cellular metabolism suggest positive health outcomes, which are not supported by current research findings regarding microwave and RF radiation. Similarly, increased bone density does not correlate with the known effects of these types of radiation on human health.
