Effects of extremely low-frequency electromagnetic field on fertility and heights of epithelial cells in pre-implantation stage endometrium and fallopian tube in mice. med./bio.

Published in: Zhong Xi Yi Jie He Xue Bao 2010; 8 (1): 56-60

Aim of study (acc. to author)

To study the effects of an extremely low frequency electromagnetic field (50 Hz, 0.5 mT) on the fertility and heights of epithelial cells in pre-implantation stage in the endometrium and fallopian tube in mice.

Background/further details

80 female rats were randomly divided into two groups: control group and exposure group. At the time of implantation, the blastocysts were obtained from the presumed pregnant mice (controlled by vaginal plug) by flushing the isolated (dissected) uterus horns.

Main outcome of study (acc. to author)

The analysis of the mean number of the flushed blastocysts in the exposed group showed a significant decrease as compared with the control group. The height of the fallopian tube epithelial cells was significantly increased in the exposed group as compared with the control group. However the height of the endometrial epithelial cells in the electromagnetic field exposed group showed insignificant increase as compared with the control group.
The authors conclude that an extremely low frequency electromagnetic field exposure has a detrimental effect on the female reproductive system in mice by decreasing the number of flushed blastocysts and increasing the height of fallopian tube epithelial cells.
