A study conducted at the Rappaport Faculty of Medicine at the Technion and the Carmel Medical Center reveals a clear connection between cell phone use and damage to the quality of the user's semen. Men who talk on the cell phone for more than an hour a day double the risk of damage to sperm concentration; Talking while charging the device and carrying it near the groin also cause similar damage

The quality of male sperm, which is constantly decreasing in Western countries, is responsible for 40% of fertility problems among couples. The research knowledge accumulated on this topic reveals that sperm quality is affected by innate genetic factors but also by environmental variables. One of them is the expanding use of cell phones.
Many studies that dealt with the question of the relationship between sperm quality and the radiation emitted from cell phones came up with different and uneven conclusions, since they were carried out under different conditions (laboratory experiments on tissues, experiments on laboratory animals, etc.) and did not always refer to the set of relevant variables.
Recently, this relationship was examined comprehensively and in depth in a study conducted at the Rappaport Faculty of Medicine at the Technion and the Carmel Medical Center. The study was conducted as part of Dr. Yulia Sheinfeld's MD thesis and under the direction of Prof.-Clinical Associate Marta Diernfeld, Director of the Fertility and In Vitro Fertilization Unit at the Carmel Medical Center.
The study referred to a wide range of variables related to cell phone usage habits and sperm quality according to the parameters established by the World Health Organization (WHO) in 2010. The study population included 106 men who were evaluated in the fertility and in vitro fertilization unit in 2011-12. The participants filled out detailed questionnaires that include demographic data and characteristics, medical conditions that may affect sperm quality, and a broad and very detailed reference to how the mobile device is used: how long does the user talk on the phone every day, where does he carry the device, does he make calls in areas with poor reception and while charging the device, etc. At the end of the data collection, the relationship between the independent variables (phone usage habits) and the sperm quality results was examined.
The results of the study indicate clear causal relationships: talking on a cell phone for over an hour a day, and talking on the device while it is connected to the charger, doubles (from 33.3% to 66.7%) the likelihood of a drop in sperm concentration. The sperm concentration dropped to an abnormal level even among men who carried the device at a distance of less than 50 cm from the groin; An abnormal concentration was found in 47.1% of them, compared to only 11.1% of the male population as a whole.
Dr. Ariel Zilberlicht, a gynecologist at the Carmel Medical Center and a faculty member at the Rappaport Faculty of Medicine at the Technion, summarizes the data: "In light of the research findings, it is definitely recommended to shorten the duration of the conversations, not to carry the device near the groin, not to sleep next to it, not to talk into it While charging (in fact, it's better to turn it off while charging), and use headphones or a speakerphone if possible." The researchers emphasize that more studies are needed, in large samples, that will examine the damage of cellular radiation in the context of male fertility.

So do a study on men who come to the fertility clinic. Is this what is called a representative sample? Even if so, is the number of those being investigated enough? Can other effects be neutralized with such a number?
Obviously, any heating of the testicles will lower the quality of the sperm, so they hang outside the body. Has anyone calculated how many degrees the temperature rises as a result of the phone? And compared to just standing in the sun for fifteen minutes a day?
But I see an opportunity for the start-up company: a heater for birth control.
50 cm is not a mistake. The radiation intensity at a distance of less than 10 cm is very high.
A distance of a few meters (1-2) from a low voltage line (230 volts = neighborhoods) to a residential building is also desirable and preferably ten to twenty meters from a high voltage/high current line. In the electrical grid, the rules are strictly followed in planning, and it is clear that someone standing at 0 distance from a power line will measure radiation, but the thickness of an electrical cabinet is at least 10 cm and that is enough to reduce the radiation 100 times from 1 cm. The radiation decreases as the square of the distance both in 50 HZ radiation and in gigahertz radiation. The dangerous radiation is mainly a magnetic field.
Whenever you can place the cell phone on a table 50 cm away from the body in general - the whole body. In the car, at work, at home, the cell phone does not have to be on us. If we are aware that it also brings diseases resulting from radiation, the effort is worthwhile, and there is nothing strange about it. Likewise, by the way, from LED lamps, from stationary computers (the power supply, the crystal, and the processor are the sources of radiation) and from a stationary computer. In the bedroom - turn them off when not working. And as above, a microwave oven. different frequency ranges. I measured radiation - we live in an invisible radiation bath of 4 milligauss per 50HZ, and milliwatts per square meter in cellular devices. Contrary to the vision that humanity lives longer, relatively young people are also seen getting sick with the terrible disease, and new diseases are emerging such as Zika, and the microcephalus phenomenon seen in Haifa Bay.
All the research was done only on men who came to the fertility institute in the first place. And more in the northern region ("small head circumferences of babies"...) and relies on questionnaires (everyone answers what they think is expected of them)... it is impossible to conclude from this about the entire population...
"Men who carried the device at a distance of less than 50 cm from the groin"
50 cm?! This is too much, there is a mistake here... I don't know a single person who puts their phone in their hat or socks.
