Thin germinal epithelium containing 1-2 layers of squamous epithelial cells was observed in the cortex, while testicular cords, the future seminiferous tubules, were noticed in the medulla (Fig.
Note: thin cortex (C, arrowhead) containing 1-2 layers squamous epithelial cells and testicular cord (asterisk) in the medulla (M).
In male embryos, the structure of testicular cords
of 14-day-old embryos was well delineated.
The results from the present study indicate that EMF exposure during fetal period has detrimental effects on testicular development and destruction of testicular cords
, which may result in subfertility on adulthood.
