Use of grayscale histogram to assess testicular changes in ram caused by heat stress

Because it detects discrete changes in tissue density, ultrasound allows an early diagnosis of physiologic changes, especially when dealing with subclinical changes. aimed to evaluate the use quantitative analysis gray scale images ovine testicles as a method for testicular caused by heat stress. Testicles from ten were insulated and then evaluated regarding echogenicity, echotexture, anatomical measurements, seminal characteristics. Echogenicity was first variable show during insulation period, well one evidence regeneration those There correlation (p < 0.05) between echogenicity sperm vigor, motility, mass echotexture motility. Echogenicity, motility decreased within four days insulation, there no change > echotexture. Testicular measurements only altered after insulation; however, structural integrity seminiferous tubules not altered. is efficient parameter degenerative process its regeneration.
