Plain English Summary
Iranian researchers exposed human sperm samples to electromagnetic waves from a 3G+WiFi modem downloading data for 50 minutes and compared them to shielded samples. The exposed sperm showed significantly reduced motility (movement quality) and velocity, particularly affecting sperm that move poorly to begin with. This matters because declining sperm quality is already a major concern for male fertility worldwide.
Why This Matters
This study adds important evidence to the growing body of research linking wireless radiation to male reproductive health problems. What makes this research particularly relevant is that it specifically tested 3G+WiFi modems during active data downloading - mimicking how these devices actually operate in our homes and offices. The science demonstrates that even a brief 50-minute exposure can measurably impair sperm function, with the most dramatic effects on sperm that were already struggling with motility. While this was an in vitro study (meaning sperm samples in a lab, not men carrying devices), it aligns with population studies showing declining sperm counts in developed countries where wireless device use is highest. The reality is that many men routinely place laptops with active wireless connections directly on their laps for hours at a time, creating exposure scenarios far more intense than what this study tested.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
The purpose of this study was to evaluate the effects of 3G+wifi modems on human sperm quality.A total of 40 semen specimens were gathered between March and September 2015, from healthy adult men.
The sperm samples were divided into two groups - 3G+wi-fi exposed and unexposed groups. In the unexp...
Mean percentage of sperm with class A and B motility were not significantly different in two groups ...
Electromagnetic waves (EMWs) emitted from 3G+wi-fi modems cause a significant decrease in sperm motility and velocity, especially in non-progressive motile sperms. Other parameters of semen analysis did not change significantly.EMWs, which are used in communications worldwide, are a suspected cause of male infertility. Many studies evaluated the effects of cell phones and wi-fi on fertility. To our knowledge, no study has yet been done to show the effects of EMWs emitted from 3G+wi-fi modems on fertility.Our study revealed a significant decrease in the quality of human semen after exposure to EMWs emitted from 3G+wi-fi modems.
