Resumen: | We have investigated the toxic effects of trichloroethylene (TCE) on the epididymis and epididymal sperm in mice. Mice were exposed to TCE (1000 ppm) by inhalation for 6 h/day for 5 days/week for 1 to 4 weeks. Segments of the epididymis (caput, corpus and cauda) were examined by light and electron microscopy. At the light microscopic level, degeneration and sloughing of epithelial cells were evident as early as 1 week after TCE exposure, and were most pronounced after 4 weeks. Such epithelial damage was observed in the caput, corpus and cauda regions of the epididymis. Ultrastructural observations revealed vesiculation in the cytoplasm, disintegration of basolateral cell membranes, and sloughing of epithelial cells. Sperm were found in situ in the cytoplasm of degenerated epididymal cells. Additionally, a large number of sperm in the epididymal lumen exhibited abnormalities including malformation of head and tail components. Our results demonstrated that exposure to TCE by inhalation causes damage to the epididymal epithelium and sperm. |
