Medical/biological Study (experimental study)

Aim of study (according to author)
The objective of the study was twofold: 1) to investigate the effect of radiofrequency electromagnetic field exposure on sperm head morphometry and the acrosome response and 2) to evaluate the consequence of exposure on the spermatozoa's zona pellucida-binding capacity.
Background/further details:
Semen samples were collected from 12 healthy donors. Spermatozoa were investigated immediately, 2 h and 24 h after exposure.

investigated material: spermatozoa

time of investigation: after exposure

Main outcome of study (according to author)
The irradiation did not affect the acrosome reaction. The analysis of morphometric parameters revealed a statistically significant reduction in all the morphometric parameters of exposed sperm samples compared with unexposed controls. There was a statistically significant reduction in zona pellucida binding in exposed sperms compared with that in controls.
The authors conclude that although radiofrequency electromagnetic field exposure did not adversely affect the acrosome reaction, it had a significant effect on sperm morphometry. In addition, a significant decrease in sperm binding to the hemizona was observed. These results could indicate a significant effect of radiofrequency electromagnetic field on sperm fertilization potential.
