In "Sans Rendez-vous", Rachel, a listener from Europe 1, wonders if there is a link between the waves emitted by smartphones and a possible decline in fertility.
For Doctor Jimmy Mohamed, it is above all an "epiphenomenon" which should not mask certain everyday things that are much more harmful for fertility.
Whether they are against an ear, in a pocket or at the bottom of a bag, smartphones are near us almost all the time.
But can the waves emitted by these devices have an impact on fertility, especially when a phone spends hours in a pants pocket?
This is the question asked by Rachel, a listener from Europe 1. It is true that "some studies conclude that the waves emitted by our phones, but also Wi-Fi, could have a toxic effect on sperm count. and their mobility ", points out the doctor Jimmy Mohamed in" Without Rendez-vous "on Europe 1.
An "epiphenomenon"
"But just because you are going to have less sperm does not mean that it will have an impact on your fertility," he reassures.
For Jimmy Mohamed, "maybe we are doing a little too much on these epiphenomena by forgetting certain everyday things", which are much more toxic, such as cannabis for example.
"If we take the men who consult a specialist for infertility, we realize that 10% of them smoke cannabis. It damages spermatozoa and destroys the mitochondria of cells [a kind of" engine "which notably ensures cellular respiration. , editor's note].

The danger of heat for men
On the other hand, Jimmy Mohamed points to the risk of having a cell phone in his pocket, or a computer on his thighs, when they heat up.
"The heat will increase the oxidative stress of the sperm, and we know that a variation of 1 degree between the temperature of the body and the bursa [which should normally be 2 degrees below the body temperature, editor's note] will cause a drop of 14% sperm. "
This is the reason why certain professions "are more at risk of infertility", further indicates the doctor.
These include bakers, cooks, or even pizzaiolos.

The effects of tobacco on women
But men are not the only ones to risk seeing a decline in fertility: women are also affected by the phenomenon. And if there is no clear data concerning the waves emitted by smartphones, the effects of tobacco are without appeal. "Smokers will take longer to have a child, and their menopause arrives on average two years before non-smokers. Not to mention that tobacco will damage the vaginal microbiota via a drop in estrogen in the blood. traces of tobacco in the vagina of smokers! "
