How you use your laptop or where you carry your phone could affect your fertility. Studies show that exposure to non-ionising radiation (EMF) in the form of cell phones, microwave ovens, laptops, or Wi-Fi can negatively effects the testes, which in turn can affect sperm count, sperm motility and increase DNA damage as well as disrupt hormones and antioxidative enzymes.
Most studies are done on sperm because they are more easily studied so even though there are not the same number of studies on female reproductive organs it it likely that the effects from EMF are similar.
