Development of a software to study echotexture of the testicular parenchyma in mammals.

To develop a software to quantify testicular echotexture, and to integrate it inside an ultrasound scanner, in order to provide a tool that will allow veterinarians and animal breeders to predict breeding potential of males.

Ultrasound examination of the testes has proven to be a valuable, noninvasive technique for evaluation of testicular pathology in males. Also, changes in echotexture in peripubertal males suggest that ultrasonography may be useful for prediction of sperm production. Image analysis of ultrasonograms can provide substantial information regarding the function and structure of tissues. An ultrasonogram is composed of an array of picture elements (pixels), with each pixel representing a determined tissue density that is displayed in a range of shades of gray (ranging from white to black). High-resolution ultrasonograms are necessary for accurate detection of extremely small variations in tissue density that can be neither appreciated nor measured by the human eye. The objective of the present project will be: (1) to evaluate the relationship between semen quality, testicular histology and pixel–intensity analysis of testicular ultrasonograms in at least, 3 mammals species: bovine, equine and porcine species. (2) to investigate the possibility to predict semen quality based on testicular pixel–intensity (3) to find critical variables and cutoff values that could explain relevant echotexture changes (4) to develop a prediction equation for semen quality based on these variables (5) to develop a software capable of taking a serie of ultrasound images from a testicle and punctuate it according to their echotexture. (6) to integrate this software in an ultrasound scanner (7) to define the best configuration for this ultrasound scanner: type of ultrasound probes, type of images or video sequences, image and video configuration (brightness, frames per second, etc).
