For decades scientists have been studying how the electromagnetic radiation (EMR) emitted by mobile phones, Wi‑Fi routers, Bluetooth devices and other wireless technologies affects the human body. One area attracting more and more attention is male reproductive health.
The most frequently studied topic is sperm quality – sperm count, motility and shape (morphology). Some laboratory and observational studies suggest that electromagnetic fields may increase oxidative stress in tissue, which is linked to sperm DNA damage and reduced fertilising ability.
Several studies, including reviews of multiple studies, have recorded lower sperm motility and viability in men who regularly keep their phone in their front trouser pocket or a laptop on their lap. Science is still working out the exact mechanism and how much the device's heat matters compared with the radiation, but the direction of the results is reason enough for sensible caution.
How to reduce exposure
- Keep your phone away from your body, especially from the groin area.
- When possible, use wired headphones or the speaker instead of Bluetooth earbuds.
- Turn off Wi‑Fi and Bluetooth when you are not using them.
- Don't rest your laptop directly on your lap – use a desk or a tray.
- Place your Wi‑Fi router away from where you spend a lot of time.
Prevention doesn't mean giving up technology – it means consciously reducing exposure.
One small step more
For those who, because of work or lifestyle, can't significantly reduce their use of wireless devices, the HSC Card and the Syn(c)Energy bracelet can be part of an everyday habit of living more mindfully with technology – a promising step in protection alongside the tips above.
If you are worried about your fertility, the most important step is talking to a doctor and having a semen analysis – early diagnosis gives the most options.
Live better. Every day.
