Study Details

The aim of the present study was to investigate Effects of 1950 MHz W-CDMA-like signal on human spermatozoa

we analyzed the effects on human spermatozoa (sperm motility and kinetic variables) induced by 1 h o...

No significant differences were observed between the EMW exposure and the sham exposure in sperm mot...

We conclude that W-CDMA-like exposure for 1 h under temperature-controlled conditions has no detectable effect on normal human spermatozoa. Differences in exposure conditions, humidity, temperature control, baseline sperm characteristics, and age of donors may explain inconsistency of our results with several previous studies
