We identified the MD values of the entire 4280 samples and analyzed the MD values of each group after classifying them according to four criteria: control group setting (non-exposure vs. All in vitro studies were experimental, whereas all in vivo studies were observational. The sperm quality parameters established in each paper varied and were subjected to a meta-analysis 16 papers provided data on sperm motility, 6 provided data on sperm viability, and 12 provided data on sperm concentration. One conference paper included in the previous study was excluded. Nine studies from a previous meta-analysis and nine new studies that included 4280 samples were used for analysis. 18 studies fulfilled all inclusion criteria and were included in the meta-analysis (Table 1 and Fig. ![]() Relationship on usage: A systematic review and updated meta-analysis Kim remarks that “additional studies will be needed to determine the effect of exposure to EMWs emitted from new mobile phone models in the present digital environment.” The bottom line is, if you’re worried about your fertility (and potentially other aspects of your health), it may be a good idea to limit your daily cell phone use.Įffects of mobile phone usage on sperm quality – No time-dependent Moreover, seeing how technologies evolve so quickly, Dr. Knowing that the number of cell phone users is most likely going to increase in the future, it’s high time we start considering exposure to RF-EMW as one of the underlying factors causing a reduction in sperm quality among the male population. Kim warns that “Male cell-phone users should strive to reduce mobile phone use to protect their sperm quality.” Considering the results were consistent across both in vivo and in vitro (cultured sperm) data, Dr. However, they found out that the decrease in sperm quality was not significantly related to exposure time-just to exposure to mobile phones itself. Another important aspect that the researchers looked into was if higher exposure time to cell phones was correlated to lower sperm quality. ![]() These findings are more refined than those from the previous meta-analysis thanks to a better subgroup analysis of the data. Overall, the results indicate that cell phone use is indeed associated with reduced sperm motility, viability, and concentration. Their paper was made available online on Jand was published in Volume 202 of Environmental Research in November, 2021. They screened 435 studies and records published between 20 and found 18-covering a total of 4280 samples-that were suitable for the statistical analyses. In an effort to bring more up-to-date results to the table, a team of researchers led by Assistant Professor Yun Hak Kim from Pusan National University, Korea, conducted a new meta-analysis on the potential effects of cell phones on sperm quality. ![]() However, this meta-analysis had a few limitations, as it had low amounts of in vivo data and considered cell phone models that are now outdated. According to a meta-analysis from 2011, data from previous studies indicate that RF-EMWs emitted by cell phones degrade sperm quality by reducing their motility, viability, and concentration. This is because cell phones emit radiofrequency electromagnetic waves (RF-EMWs), which are absorbed by the body. They can have negative effects on health. But cellphones also have their downsides. That clearly indicates the connection between cell phone and decreasedĬredit: Pusan National University Cell phones have succeeded in bringing the world closer, making life tolerable during a very trying time.
