Sperm damage after whole body exposure of mice
The reported finding
After five weeks, exposed mice had lower sperm vitality and motility and increased sperm DNA fragmentation. Oxidative DNA-base damage increased across exposure periods.
Reading it carefully
Fertilisation and blastocyst development were not impaired in the study. The affirmative claim concerns sperm damage, not a demonstrated loss of fertility.
Inside the study
Exposure conditions
905 MHz; reported whole-body SAR 2.2 W/kg; 12 hours/day for 1, 3 or 5 weeks.
Design & controls
Sham, untreated and RF groups. Figure 5 sperm function n=5-8 mice/group; Figure 7 fragmentation n=5-8, comet n=3, 8-OHdG n=3-5; testis histology n=3. Exposure was 905 MHz, whole-body SAR 2.2 W/kg, 12 h/day for 1/3/5 weeks.
Related research & shared cohorts
The protection question raised
Can sperm functional and DNA changes have consequences beyond the measured period? Fertilisation and early embryo development were not impaired here, so cellular injury and demonstrated reproductive impairment remain separate questions.
