| Chamber | The coils were placed face to face vertically and horizontally in a Faraday cage (130 x 65 x 80 cm) |
| Setup | Animals were exposed in Plexiglass cages (32 x 18 x 15 cm). Animals for sham exposure were kept under the same condition but in the absence of magnetic field. |

The data showed that 50 and 100 days of exposure to a 1 mT extremely low frequency magnetic field can cause alterations at the cellular level and in malondialdehyde concentration.
Ultrastructural dissolution, decrease in cell organelles, cavities in cells, and typical structural loss of the nucleus were revealed in germinal epithelial cells of the ovaries in the 50-days exposure group. Ultrastructural alterations in germinal epithelium and tunica albuginea of ovaries, irregularity in nucleus and nucleolus, increase in lipid vacuoles of cell cytoplasm and reduction in organelles were found in ovaries in the 100-days exposure group. Similar alterations were observed in uterus.
Malondialdehyde concentration of the ovaries and uterus increased in rats of the two exposure groups.
