“…Ceylan et al 22 studied the temporary stretch of spermatic cord of Wistar rats using a traction mechanism similar to this study and assessed the damage in the testis and vas deferens, but not measured testicular volume. Choi et al 23 evaluated the effects of compression and stretching of the spermatic cord of SpragueDawley rats using a vascular sling, but did not measure the traction force.…”

PURPOSE:To compare the measurement of the testicular volume of Wistar rats using a caliper and ultrasonography. METHODS:Forty Wistar rats were randomly assigned into four groups. A tensile force of 1.6 Newton (N) and 1.0 N was applied to the right spermatic cord in group I and group II, respectively. Group III was the sham group, and group IV served as a control. The initial and final testicular volumes were measured using a caliper and ultrasonography and compared. A significance level of 5% was used. RESULTS:The Kappa coefficient was equal to 0.292 (p = 0.006). The Pearson correlation coefficient obtained for the percent reduction in the right testicular volume using ultrasonography and a caliper was equal to 0.696 (p < 0.001). CONCLUSION:There was reasonable agreement and a significant positive correlation between the percent reduction in the right testicular volume using ultrasonography and a caliper.

“…Surgeons know that they should delicately handle these structures; however, they do not know the intensity of the traction force being applied during the intraoperative period. However, it seems that autoimmunization in humans is an unlikely cause, at least in the long term, of contralateral testicular lesion [11][12][13][14][15][16] .…”

PURPOSE:To determine whether tension in the spermatic cord of rats causes lesions in the testis, epididymis or vas deferens. METHODS:Forty Wistar rats were randomly allocated into four groups. A traction force of 1.6 Newton (N) in group I and 1 N in group II was applied to the right spermatic cord. Group III was the sham, and group IV served as the control. RESULTS:Testicular lesions occurred on the right side in 66.7% of the rats and on the left side in 46.1% of the rats. The testes showed a decreased number of Sertoli cells, necrosis and a decreased number of germ cells in the seminiferous tubules. Anatomopathological changes in the vas deferens were not identified. There was no decrease in the thickness of the muscle wall of the vas deferens. In the right epididymis, 71.8% of the animals showed a reduction and 5% showed an absence of intraluminal sperm. In the left epididymis, 37.5% of the rats showed a reduction. The volume and the final testicular weight of the right side in group IV was different from those in the other groups. CONCLUSIONS:Anatomopathological lesions were found in the testis and epididymis.

“…Diversas vias de acesso podem ser utilizadas para abordar o funículo espermático de ratos: laparotomia mediana 41 , incisão inguinal 19,42 , inguinoescrotal 15 , supraescrotal 18,40 e escrotal 43 . Optou-se, neste estudo, pelo acesso supraescrotal direito, a fim de evitarse a manipulação inadvertida do conteúdo escrotal no lado esquerdo, para reduzir a possibilidade de aderência do testículo na parede escrotal e para diminuir o edema, o processo inflamatório e a pressão intraescrotal no pós-operatório 44 .…”

“…Nesta pesquisa houve concordância razoável e correlação positiva, que foram significantes em relação à redução percentual do volume testicular direito pelo exame ultrassonográfico e pelo paquímetro nos ratos dos grupos I, II e III. Evidenciou-se redução do volume testicular final nos grupos em que houve manipulação e aplicação da força de tração no funículo espermático, tendo isso sido também relatado por outros autores 17,19 .…”

“…Trata-se de um tubo muscular que possui três camadas de musculatura lisa dispostas da seguinte forma: a camada média é circular e as camadas externa e interna são longitudinais 31,60,61 utilizaram essa classificação histológica para examinar testículos de ratos submetidos à fasciotomia descompressiva após torção testicular. A classificação histológica de Johnsen 67 também tem sido utilizada para avaliar testículos de ratos 17,19,55,68 . Todavia, essa classificação histológica foi idealizada inicialmente para registrar a espermatogênese em testículos de seres humanos, permitindo fazer a correlação entre as doenças endocrinológicas e o comprometimento da função testicular 67 .…”
