Summary
The use of phones can have a detrimental effect on sperm quality and testosterone levels. Phones emit radio frequency waves and electromagnetic fields (EMFs) which can negatively impact the brain, heart, endocrine system, and reproductive function. Carrying the phone in the front pocket can reduce sperm count and motility. Even if Wi-Fi or cellular access is turned off, the heat-related effects of the phone can still affect sperm quality. To mitigate these effects, it is recommended to keep the phone away from the groin or as far as possible.
