The effects of electromagnetic field on the microstructure of seminal vesicles in rat: a light and transmission electron microscope study med./bio.

Published in: Pak J Biol Sci 2008; 11 (5): 692-701

Aim of study (acc. to author)

To investigate possible effects of exposure to 50 Hz electromagnetic fields on the cytoarchitecture and microstructure of the seminal vesicles.

Main outcome of study (acc. to author)

In the exposure group epithelial and basal cells showed significant destructions presented by heterochromatin and dense nuclei. In the stromal connective tissue cell debris and abnormal areas were recognizable. Obvious vacuolization was found within the epithelial cell cytoplasm and also between the cell organelles. The nuclei of the endothelial cells of the blood vessels were more rigid and endothelial cell cytoplasm contained a lot of vacuoles and pinocytotic vesicles.
The results suggest that electromagnetic field exposure may cause profound changes in the seminal vesicle tissues. Therefore exposure to electromagnetic fields may result in pathological changes that could lead to infertility.
