Effects of High-Energy Shock Waves on Testes of Wistar Rats
1993
The effects of high-energy shock wave (HESW) on testes are still unknown. We investigated Wistar rats at 3 months of age for morphologic and functional changes in the testes and in serum follicle-stimulating hormone (FSH), progesterone (Prog), and testosterone (T). In an initial study, 12 rats received 1000 shocks at 19 kV directed at their testes using the JDPN-IV lithotripter. Two animals were sacrificed, and their testes were step-sectioned for light and electron microscopic examination on the operation day and on postoperation days one, two, four, eight, and sixty. There was angiectasis and congestion (58%) and focal hemorrhage (42%) in the testicular tissue, as well as mitochondrial swelling, reduction or disappearance of mitochondrial cristae (42%), and degranulation of the rough endoplasmic reticulum (33%) in spermatocytes. In the definitive study, groups of 10 rats were exposed to the same power index directed at their testes. One week after this exposure in Group 1 and at 3 and 6 weeks in Group 2...
