“…echogenicity ranging from low to moderate, regardless of the testicle (right or left) and the scanning plane used. Instead, they found that the echogenicity increased in direct proportion to the age of the animals, corroborating the results of Cartee et al [11], and Moura et al [12].…”

The objective of this study was to determine the minimum representative area to evaluate testicular echotexture parenchyma and to identify the correlations between the intensity of pixels of the testicular parenchyma and the fibrosis score with the physical and morphological characteristics of the ejaculate of Texel rams. The study used 88 Texel rams, aged between 10 and 12 months, and reared in a semi-extensive system. The animals underwent breeding soundness evaluation (BSE) and ultrasound of the testicles. The images were transferred to a computer where they were defined in areas of 400, 1600, 3600, and 6400 mm 2 , after which the average intensity of the pixels of each image of the testicular regions was evaluated. A testicular fibrosis score was assigned in order to quantify the frequency of fibrotic lesions. In relation to the intensity of pixels of the predetermined regions, only the area of 400 mm 2 presented a difference (P < 0.05), with the area of 1600 mm 2 being the smallest area that best represented the testicular parenchyma. There were no correlations between the intensity of pixels of the testicular parenchyma and the fibrosis score with the physical and morphological characteristics of the ejaculate of the rams.

“…The mediastinum testis was represented as a hyperechoic line in longitudinal images. These observations are similar to those described for boar [28], dog [29], bull [30], rams and male goats [17] and camels [31]. Ahmad et al [32] recorded an increase in the echogenicity of testicular parenchyma with advancement in age of the bull; the mean number of pixels of testicular ultrasonograms increased significantly up to 24 mo of age and then leveled off as the age increased.…”

“…In animal studies trans-scrotal ultrasonography has been shown to demonstrate the ultrasonic morphology of testes of bulls [38], rams and boars [28]; to assess testicular trauma, evaluation of testicular swelling or masses [39], infertility [40], male hypogonadism [41], testicular interventions etc. It is also helpful not only for diagnosis of testicular torsion, cryptorchidism, scrotal hernia, varicocoele but also follow-up of testicular microlithiasis [42].…”

This study was designed to evaluate the effectiveness of recombinant Ovalbumin-LHRL (OL) immunization on changes in testicular size, histological appearance and testosterone production in buck kids. Thirty native buck kids at 18 weeks of age were divided into three groups, control (n = 10), immunization (n = 10) and castration (n = 10) groups. Immunized animals received OL protein generated by recombinant DNA technology. Ultrasonographic and histological examinations of the testes were performed. Animals were slaughtered at 44 weeks of age. Semen and epididymides were evaluated for the presence of sperm cells. Immunized animals generated anti-LHRH antibodies. Testosterone production, testicular and accessory glands development and sperm production were suppressed in the immunized animals (p < 0.01). Semineferous tubule diameters decreased (p < 0.01), basal membrane of the tubule was thickened and hyalinized in immunized kids. Immunization affected ultrasonographic appearance of the testes drastically. While testes of control animals gained their normal ultrasonographic appearance as the age increased, immunized animals had uniform hypoechogenic testicular structure as observed at 18 weeks of age until slaughter. Simultaneous histological and ultrasonographic evaluations indicated that the changes in testicular histology could partly be monitored via ultrasonographic imaging; nevertheless, it is difficult to claim that ultrasonographic image reflects the exact changes in such instances. In conclusion, these results indicate that recombinant OL fusion protein is effective in immunocastration in buck kids and has a potential to be used as an alternative to physical castration. Further researches should be conducted to help assessing reproductive status of testes from ultrasound images.
