Eighty-one mixed breed intact male dogs were divided into three groups: Group 1 = left testicle biopsied by Trucut needle method (n=36); Group 2 = left testicle biopsied by Incisional method (n = 39); Group 3 = not biopsied (n = 6). The dogs were castrated 1 to 36 d following biopsy. The biopsy specimens and both testicles were examined for gross and histologic lesions. There was no effect of biopsy on testicle circumference. There was a positive correlation (r(2) = 0.93) between testicular circumference and occurrence of lesions. Incisional biopsies induced more gross lesions (67 vs 33%), and more histologic lesions (135 vs 43). The histologic lesions included hypospermatogenesis, coagulation necrosis, tubular degeneration, interstitial fibrosis and inflammation. In addition, the lesions observed in Incisional biopsy specimens were of greater severity and incidence than Trucut biopsy specimens (87 vs 35%). It was concluded that Incisional biopsy induced an increase in frequency and severity of lesions compared with Trucut biopsy of the canine testicle.
