“…Torsion of the spermatic cord causes strangulation of gonadal blood supply with subsequent testicular necrosis and atrophy, and results in diminished fertility in experimental animals. 12,13 Burdizzo castration has been shown to have no effects on most of feedlot performance traits and blood metabolites. 14 Higher peak cortisol concentration following surgical and banding castration was earlier observed.…”

Background: Castration is one of the frequent management practices in large animal husbandry and burdizzo castration has been shown to produce fewer long-term behavioral signs of pain and distress than banding. Castration is known to reduce virility and aggression due to the elimination of testicular androgens. Methods: This is a comparative study of hematological and biochemical parameters in intact, acute and chronically castrated West African dwarf goats. Twelve adult West African Dwarf bucks weighing between 8 to 14 kg randomly divided into 3 groups of intact, acute and chronic castrated. They were castrated using burdizzo castrator. Hematological and biochemical parameters were estimated by standard laboratory procedures. Results: There were significant decreases (P<0.05) in the PCV, Hb, RBC, WBC and MCH of acute and chronically castrated goat compared to the control group. The MCV and platelets increased significantly in acute and chronically castrated goat; while the neutrophil and lymphocyte showed no significant changes. The result also showed no significant changes in Na , AST and Creatinine. Mg 2+ and ALT significantly increased in chronically castrated goats compared with the acutely castrated goats while Zinc increased significantly (P<0.05) in acute castrated compared with the control goats. Conclusions: Therefore, from this study, either acute or chronic castration in goats have no detrimental effect on blood electrolytes, but mainly deter the hematopoietic process in the animal owing to testosterone and androgen depletion in castrate animals.

“…an intravaginal torsion. 7 In TT within the sheath, HCDU can easily identify the "whirlpool sign" above or posterior to the testis owing to TT. However, the whirlpool sign in TT outside of the sheath is difficult to identify using high-frequency colour Doppler ultrasonography, as perinatal TT is an extravaginal torsion.…”

contributed equally to this study.Objective: The goal of this study was to elucidate the different sonographic features of prenatal and postnatal testicular torsion (TT) using high-frequency colour Doppler ultrasound (HCDU) in an effort to increase diagnostic accuracy. Methods: 29 patients (average age, 7.5 days) with perinatal TT were divided into patients with postnatal (acute) TT vs patients with prenatal (chronic) TT and their clinical characteristics, imaging features on HCDU and surgical pathology results were retrospectively analyzed. Results: Significant differences were observed between prenatal and postnatal TT cases with regard to testicular size (p 5 0.01) and echogenicity (p 5 0.007). All 17 prenatal cases had non-homogeneous testicular parenchymal echo patterns compared with only 9 (64.3%) postnatal TT cases. Five postnatal TT cases presented with homogeneous echo patterns compared with none of the prenatal TT cases. Testicular blood supply was absent in 25 (80.7%) of 31 testes on colour Doppler flow imaging, with the majority occurring in the prenatal TT cases [i.e. 16 (94.1%) cases]. 1 affected testis out of a total 17 testes from 16 patients with prenatal TT was salvaged, with a salvage rate of 1/17 or 0.06%. 7 affected testes out of a total 16 testes from 13 patients with postnatal neonatal TT were salvaged, with a salvage rate of 7/16 or 43.8%. Conclusion: In neonates with acute scrotal symptoms, the possibility of perinatal TT should be considered and HCDU examination should be performed in a timely manner. HCDU examination could aid in testicular salvage by prompting quick surgical intervention. Advances in knowledge: This study underlined the clinical contribution of HCDU in evaluating postnatal (acute) vs prenatal (chronic) TT. The sonographic features of postnatal TT with salvageable testes were compared with prenatal torsion and the relative salvage rates in both cases were discussed.

“…Perinatal testicular torsion usually presents as a bluish-black discoloration of the scrotum associated with a scrotal swelling. Its management is controversial, due to the low viability of the testis and the possibility of bilateral torsion [3][4][5]. We present a case of a neonate with bilateral testicular torsion.…”
