    A study (Titled ĎImage content influences menís semen qualityí) has found that cell phones are detrimental to male sperm quality (Lower sperm motility and sperm concentration). Itís original goal was to determine if image content has a effect on sperm quality, but accidentally discovered that men who said they kept their phone in their pocket had worse sperm quality than those who didnít have a phone in their pocket. As far as I can tell, from my limited knowledge, the study isnít very flawed. What I do know is that they used 52 men, which doesnít seem like a lot.


    Another possible flaw is in regard to how they took sperm samples. Sperm parameters can vary amongst healthy individuals, the WHO recommends taking at least 2 samples to determine fertility. This study took one sample from all 52 men, then asked them if they wanted to participate the second time around and only 25 men agreed. So, they did take more than one sample but only for 25 men. Iím not sure, but this doesnít seem like very good methodology as only 25 of the samples are representative.


    Another issue is that the study had a variable that it changed from person to person. As stated, itís original goal was to find out if image content affected sperm quality, and they concluded that it can. They gave different images to each mam, meaning that some of the images would have had a detrimental affect to the sperm quality. So, they could have gave a healthy cell phone user a type of image that causes poor sperm quality. However, it would be coincidental that cell phone use was still correlated with poor sperm, even if the study randomly gave out out different images to different people that could cause poor sperm in the analysis the ones with poor sperm.


    Also, the study was done in 2004, just year after 3G came out and 6 years before 4G, so it isnít very modern.


    I was wondering if certain lifestyle factors that tend to be associated with phone use where causing the infertility, not the phones themselves, but the study had a very extensive questionnaire and adjusted for many different factors from bathing habits to diet, so I donít think that the study can be flawed in this are. What do you guys think? Is this something that we should be worried about and change our habits over, or is it scientifically limited and no cause for alarm until bigger and better studies conform their findings?

    You certainly present an interesting topic. It seems rather remarkable that viewing images would have any impact on sperm issues as one would think that such mental aspects would not affect a normal, physiological function, but it apparently does.

    It would seem that the study has enough participants and controls to at least get an idea about the validity of such image results. Moreover, fertility clinics appear to have established a link in image issues with sperm donors, so the image aspect appears valid, at least to some extent.

    The radiation issue also appears to have some cause for concern, assuming you wish to have healthy sperm to help keep the human population ramping up.

    A study from 2014 using isolated sperm with or without a mobile phone in their immediate vicinity is related. After five hours. the control group showed no changes, but the sperm exposed to the EM of a cell phone had reduced motility and more DNA fragmentation.

    While this is only one study (there are almost certainly others), it might be cause for concern not only for sperm, but the rest of one's body, relative to DNA damage. Aside from saving a lot of money, there may be another very good reason to avoid cell phones and Wi-Fi devices as much as possible, especially for younger people. The longer the exposure, the greater the damage, as it is mostly irreversible.

    This all sounds extremely unlikely to me. The bit about images strikes me as ridiculous.But as you don't seem to have provided any reference to the research you are talking about, it is rather hard to comment definitively. What study was this, and can you give us a link so we can read about it?

    Can you provide a link to the study you are talking about?

    There is what looks like a balanced evaluation of some 2016 Israeli work here: https://www.nhs.uk/news/lifestyle-an...sperm-quality/
