Abstract
The effect of magnetically pregenerated water structures was studied on oestrous cycles (OC) and body weight changes in cycling female albino mice. The result showed that exposure time-dependent, magnetically generated water structures produced by different polarities of a magnet produce differential effects on the OC and body weight of cycling mice. We believe that magnetically induced water structures may have caused these effects by influencing states of the central nervous system, activities of the gonadal hormones, and thus altering the physiological processes of cycling mice.
