Aim of study (acc. to author)

To study the effects of electromagnetic field exposure from GSM base stations on the induction of sperm head abnormalities in mice.

Background/further details: Three groups of mice (each n=5) were exposed under different conditions: 1) GSM base station exposure near residential environment, 2) GSM base station exposure near an office block, 3) control group (300 m away from any GSM base station).
