Abstract

A study was made of the effect of interrupted EMF SW of 500 and 250 V/m on endocrine glands of male rats. The following changes were noted: activation of neurosecretion in hypothalamus, inhibition of adrenocorticotropic and gonadotropic functions of hypophysis and adrenal cortex, degenerative and dystrophic changes in testes. The observed disorders were aggravated as the intensity of the field and duration of exposure increased.

Main findings

Interrupted short-wave EMF exposure at 500 and 250 V/m was associated with activation of hypothalamic neurosecretion, inhibition of adrenocorticotropic and gonadotropic functions of the hypophysis and adrenal cortex, and degenerative/dystrophic changes in testes. Reported disorders increased with higher field intensity and longer exposure duration.

Outcomes measured

  • Neurosecretion in hypothalamus
  • Adrenocorticotropic function of hypophysis
  • Gonadotropic function of hypophysis
  • Adrenal cortex function
  • Testes degenerative and dystrophic changes

Limitations

  • Frequency of the short-wave EMF not reported in the abstract
  • Exposure duration not specified in the abstract
  • Sample size not reported in the abstract
  • Study design details (randomization, controls, blinding) not described in the abstract
