Tree Cerdocyon thous males received different anesthesia protocols: tiletamine-zolazepan (7mg/kg); ketamine-xylazine (12 and 1mg/kg); ketamine-xylazine-atropin (12, 1.0 and 0.04mg/kg), ketamine-midazolam (12 and 0.5mg/kg) and ketamine-acepromazine (12 and 0.1mg/kg) for semen collection by electroejaculation, testosterone hormonal dosages, fine needle aspiration cytology (FNAC), testicular manual evaluation, biometry by caliper and ultrassonography (US). The ejaculates collected by electroejaculation showed urine contamination making impossible the semen evaluation. The M±PD of serum testosterone was 0.74±0.2ng/mL. The cell types found in FNAC were: spermatogonia 13.3±11.5%, primary spermatocytes 5.5±1.1%, secondary spermatocytes 5.5±3.9%, early spermatids 12.8±6.2%, late spermatids 26.2±11.2%, sperm 14.5±4.7% and Sertoli cells 21.8±2.7%. Manual testicular evaluation showed normal consistency of testicles. The M±PD of testicular biometry by caliper was 3.8±1.5cm³ and by US was 1.1±0.3cm³. The animals showed normal spermatogenesis with normal spermatozoa observed in FNAC and normal testicular US.
