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. They screened 435 studies and records published between 2012 and 2021 and found 18—covering a total of 4280 samples—that were suitable for the statistical analyses. Their paper was made available online on July 30, 2021 and was published in Volume 202 of Environmental Research in November, 2021.
Overall, the results indicate that cell phone use is indeed associated with reduced sperm motility, viability, and concentration.

Correlation is not causality. I think that the study is questionable. You would have to rule out other factors.
