Radiation effects over male fertility (mobiles, Wi-Fi, microwaves, etc.)

Some
electronic devices, such as mobile phones, laptops, Wi-Fi, and microwave ovens,
generate non-ionizing radiation that can affect male fertility. This is
revealed by one of the latest reviews recently published by Agarwal’s research
group in Cleveland, USA (Kesari et al., 2018).

These devices generate radio frequency electromagnetic fields that applies a detrimental effect on different parameters that measure sperm […]
