Do Cell Phones Lower Sperm Counts?

August 27, 2019

[Music] are men talking the reproductive health away there have been unexplained declines in semen quality reported in several countries my cell phones be playing a role as radiofrequency electromagnetic radiation from these devices could potentially affect sperm development and function the cell phone industry bristles at the r-word radiation preferring the more innocuous sounding RF EMFs they do have a point though about it being used by snake oil hucksters of radiation protection gadgets radiation need not be atomic bomb gamma rays but just a warm glow of sunshine on your face that’s radiation too the question is does the specific type of radiation emitted by cellphones affect male fertility after the World Health Organization declare the cellphones could possibly cause brain cancer many folks were like no problem just keep it in my pants and use Bluetooth or something away from the brain but close to the gonads put all the studies together including nearly 1,500 semen samples and exposure to mobile phones was associated with reduced sperm motility and viability zone unnecessarily sperm concentration how much less could they swim sperm motility only appeared to be about 8% less and so that alone may not actually translate into reduced fertility unless you’re starting out with a marginal sperm count in the first place so especially for men who already have fertility problems it might be better to avoid keeping an active cell phone next to your crotch for long periods of time cell phones may just be one of a bunch of things that could potentially add up for example Wi-Fi may be an issue so research has got semen samples more than a thousand guys and the total number of swimmers motile sperm were decreased and a group who used wireless internet okay but these were all just observational studies maybe men who use Wi-Fi just tend to smoke more or do more horseback riding or something and that’s the reason for the apparent link you don’t know until you to the test unfortunately many of the studies are like this on rats so while the microwaves emitted from a cell phone do not appear to affect rat testicles it can be argued that you can’t necessarily extrapolate from these animal models since for example there scrotums are non pendulous meaning their testicles are more inside their bodies rather than out swinging around so at least until proven otherwise it’s recommended that men with fertility issues may not want to keep their cell phones in their front pants pocket in close proximity to their testicles even when not in use cell phones emit radiation to keep pinging their location though the main exposures during talk mode where it may still remain the pocket thanks to headsets these days and then what happens when you have it in proximity to other common metal objects here’s a cross section at crotch level there’s the phone you may have a metal zipper keyring in your pocket you know when all three objects were added the SI or the amount of radiation absorbed into the testicles was generally increased even approximately double but that’s only a problem if the radiation does actually damage sperm how hard is it to just design a study where you just wave a cell phone over some human sperm in a petri dish to see if it’s an issue and here we go significantly more DNA fragmentation in sperm exposed to cellphone radiation starting within an hour of exposure such a dramatic effect that they suggest women might not want to pocket their cellphones for a few days after trying to get pregnant so as to not put the sperm at further risk [Music] you

    You know it's even more ironic that a number of the "negative ion" pendents and cards people buy to block the emf from phones actually emit nuclear radiation, ( alpha beta and gamma) as they contain thorium and other rare earth metals. I would personally settle for cell phone radiation down their but that's just me.

    First of all read your cellphone instruction (available in menu): guaranteed safe distance of use is is about 1.5 inch at all times, while your clothes or purse may provide 0.15 of an inch in thickness, and when you talk you hold your phone in direct contact. Second thing is accumulative effect: under how many cell phones signals are you in a bus during rush hour? How many wifi spots can your phone catch in the room where you study/sleep/work? Third: the machine which measures SAR, which is basically how much radiation goes to your brain while talking on the phone, is modelled on the skull of a standard male American soldier. Now think about how this standard relies to you (if you're female for example), and how many times thinner a childs / youngsters barrier is different from the standard American soldier?

    AT what distance does the radiation dissipate and what would block it? I am thinking that a wallet-style phone case might provide sufficient protection against the weak radiation of a phone. I would want a lead-lined wallet case, but maybe the radiation is weak enough that it can be blocked by the case and reduce exposure dramatically.

    was the EM field intensity somewhat close to the one we might get exposed to ? The graphs and their legend don't tell about it. I mean, in a microwave hoven you would have the same result. Intensity is investigated only in the beginning of video, with appropriate studies. But the last, that is the concluding one, don't give us youtube watcher any idea about the fact it is not another FUD study to claim more funds for further researches.
    EDIT : ok, i looked to the summary linked in the "sources" page on nutrition facts. The methodology is quitte simple and strong, totaly representative. Results should be confirmed by other studies quitte easily. Thanks for the good work.
    32 healthy men with normal semen parameters were selected for the study. Each sperm sample was divided into two equal portions (A and B). Portions A of all involved men were placed for 5 hours in a thermostat, and portions B were placed into a second thermostat for the same period of time, where a mobile phone in standby/talk mode was placed. After 5 hours of incubation the sperm samples from both thermostats were re-evaluated regarding basic motility parameters. The presence of DNA fragmentation in both A and B portions of each sample was determined each hour using a standard sperm chromatin dispersion test.

    What gets me is our government that we pay pretty good taxes to support, arent they supposed to be looking at this type of thing and put some type of rules and regs? One Problem with a Capitalist way of life is the cost of things, and maximum profits take precedence over health and safety. FDA is guilty of these type of things as well. So why is it in some countries they limit these type of things, weather its cell phones, or hydrogenated oils in foods for example, yet here in the "Good Ol' US of A" our government is hiding in the closet with what? Kick back money from the companies? It boggles the mind. So millions of phones out there, WIFI etc…just because YOU turn it off in your home, or apartment, doesn't mean the WIFI from your neighbors Gigabit router isn't going to affect you. Or how about the Cell Phone Tower that is 2 blocks from your house? Your phone is off yeah, but you think those Towers wont affect you? Who is doing anything about this? People, think about it…if you really think you turn off your wifi in your home, or dont own a cell phone that your safe from this potential threat? I am sad to say…your mistaken.

    I love your channel and you. The last line sounds so male centric. What about what that cell phone might do to the DNA that’s in the egg? While the study is about sperm, and this video is about sperm, that last line was galling. Perhaps women shouldn’t pocket a cell phone to protect themselves, too. Just have to say it. Men get all of the money for research and so I understand where this is coming from, and I don’t blame you.

    There are clothes made with silver and/or stainless steel fibers that protect against emfs. I notice a huge improvement in my energy and focus when I wear these clothes over or under my garments. I use a hat liner under knit caps and I don't get headaches as when I go without protection from all these cell phones towers and wireless routers at work. If we could only SEE the emf pollution, people would be running for the hills.

    To decrease the radiation exposure download the app Macrodroid to automatically give the instructions to your phone to turn off wifi, Bluetooth, location and nfc services when you turn off the screen. If interested and don't know how to do this just leave a comment below and I'll share my macros or setting with you.

    Please see the research on EMFs, somewhat brief,

    The Harmful Effects of Electromagnetic Fields

    1) Microwave EMFs activate voltage-gated Ca2+ channels (VGCCs) concentrated in the brain), (elevates blood pressure and/or heart rate)

    2) neuronal cell demyelination (Long-term exposure to 835 MHz RF-EMF induces hyperactivity, autophagy and demyelination in the cortical neurons of mice

    3) autophagic degradation in cortical neurons against a stress of 835 MHz RF Activation of autophagy at cerebral cortex and apoptosis at brainstem are differential responses to 835 MHz RF-EMF exposure.

    4) The results showed that EMF caused a significant decrease in total pyramidal and granular cell numbers in the hippocampus, and DG and in Purkinje cell numbers in the cerebellum in the EMF group compared to the other groups (p < 0.05). Effects of 900-MHz radiation on the hippocampus and cerebellum

    5) Effects of 2.4 GHz radiofrequency radiation emitted from Wi-Fi equipment on microRNA expression in brain tissue. Long-term exposure of 2.4 GHz RF may lead to adverse effects such as neurodegenerative diseases originated from the alteration of some miRNA expression

    6) Radiation From Mobile Phones Changes Protein Expression In Living People, Study Suggests

    7) Cell Phone Radiofrequency Radiation Exposure and Brain Glucose Metabolism (increases barin glucose metabolism)

    8) Exposure to 835 MHz RF-EMF decreases the expression of calcium channels, inhibits apoptosis, but induces autophagy in the mouse hippocampus

    9) RF-EMF-exposed cases: (1) significant morphological lesions in the myelin sheath of rats; (2) a greater risk of multiple sclerosis in a study subgroup; (3) effects in proteins related to myelin production; and (4) physical symptoms in individuals with functional impairment electrohypersensitivity, many of which are the same as if myelin were affected by RF-EMF exposure, giving rise to symptoms of demyelination. In the latter, there are exceptions; headache is common only in electrohypersensitivity, while ataxia is typical of demyelination but infrequently found in the former group. Overall, evidence from in vivo and in vitro and epidemiological studies suggests an association between RF-EMF exposure and either myelin deterioration or a direct impact on neuronal conduction, which may account for many electrohypersensitivity symptoms.

    10) Could myelin damage from radiofrequency electromagnetic field exposure help explain the functional impairment electrohypersensitivity? A review of the evidence.

    Symptoms: Among the more commonly reported changes are sleep disturbance/insomnia, headache, depression/depressive symptoms, fatigue/tiredness, dysesthesia, concentration/attention dysfunction, memory changes, dizziness, irritability, loss of appetite/body weight, restlessness/anxiety, nausea, skin burning/tingling/dermographism and EEG changes.

    To recap, it takes a pretty short time frame to cause neuronal damage/death 60 min/day, once per day (workplaces, schools, churches, stores). The EMF, EFA and EBS groups were exposed
    to 900-MHz EMF radiation inside a tube once daily over 21 days (60 min/day). The solution is to ask to turn off WIFIs, smart phones (flip phones, non 5G, emit far less EMFs.), use an Ethernet (hard wired) connection and to measure. The new 5G cell technology emit much greater EMF signals.
    If you do want the hard evidence is to measure, I purchased a meter Acoustimeter AM-10 (but doesn’t do a good job at measuring at 5Ghz levels), the cost is about $370, but I find it very useful. The is also Gigahertz Solutions HF35C RF Meter (You wouldn't believe the levels at some places and public parks, the new 5G technology is much worse in terms of EMFs.) I purchased from a Canadian company. There is a company here in the States,, but they hype up their products. I have no affiliations with either company. is also available through Amazon.
