Exposure to electromagnetic waves from 3G+Wi-Fi modems significantly decreased sperm motility and velocity.

Plain English Summary

Summary written for general audiences

Researchers collected 40 semen samples from healthy men and divided them into exposed and unexposed groups. The exposed group was placed in an incubator with a 3G+Wi-Fi modem downloading data for 50 minutes, while the unexposed group was shielded with aluminum foil. Sperm motility class C was significantly lower in the exposed group, while class D was significantly higher. Several velocity parameters were significantly higher in the unexposed group. The authors concluded that electromagnetic waves from 3G+Wi-Fi modems significantly decrease sperm motility and velocity.

Why This Matters

The study found no significant difference in progressive motility (class A and B) between groups. The researchers noted that the in vitro design was a limitation. They used a Kolmogorov-Smirnov study and a paired t-test to compare semen parameters.

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.

Quick Questions About This Study

Exposed samples were placed in an incubator with a 3G+Wi-Fi modem actively downloading for 50 minutes, while unexposed samples were shielded with aluminum foil.
Class C motility was significantly lower in the exposed group, while class D motility was significantly higher. Classes A and B showed no significant difference between groups.
Velocity curvilinear, straight line, average path, mean angular displacement, lateral displacement, and beat cross frequency were all significantly higher in the unexposed group.
The authors concluded that electromagnetic waves from 3G+Wi-Fi modems cause a significant decrease in sperm motility and velocity, especially in non-progressive motile sperm.
The study's limitation was its in vitro design.
