Effects of exposure to a mobile phone on testicular function and structure in adult rabbit. (RETRACTED) med./biol. By: Salama N, Kishimoto T, Kanayama HO
Published in: Int J Androl 2010; 33 (1): 88 - 94 ( PubMed Entry , Journal web site )
Aim of study (according to author)
To study the accumulating effects of exposure to mobile phone emission (12 weeks, 8 h daily, standby position) on testicular function and structure of rabbits. (The study was retracted by publisher (Rajpert-De Meyts 2012).)
24 adult male rabbits were randomly and equally divided into three groups: 1) mobile phone exposure, 2) sham exposure group, and 3) cage control group. Semen analysis and sperm function tests were conducted weekly.
General category: mobile communication system, digital mobile phone, GSM
FIELD View further expo parameters
animal (species/strain): rabbit/New Zealand White
partial body exposure: testes
Methodsinvestigated material: isolated bio./chem. substance (in vitro), DNA/RNA (in vitro), intact cell/cell culture (in vitro), tissue slices (in vitro), isolated organ (in vitro), semen (ejaculate); sperms; blood samples
investigation on living organism
investigated organ system: reproductive system
time of investigation: before, during and after exposure
Main outcome of study (according to author)
Compared to the control groups (groups 2 and 3) a decrease in the sperm concentration appeared in the exposure group at week 6. This became statistically significant at week 8. There was no difference in motile sperm population amongst the three groups until week 10 when it declined significantly in the exposure and sham exposure groups (with more significant decline in the mobile phone exposed animals). Histological examination showed also a significant decrease in the diameter of seminiferous tubules in the mobile phone exposure group versus the two control groups. The other study parameters did not show any difference.
In conclusion, low intensity pulsed radiofrequency emitted by a conventional mobile phone kept in the standby position could affect the testicular function and structure in adult rabbits.
