Abstract
A study was performed to determine if performing testicular biopsies or epididymal aspirates in dogs would induce sperm-bound anti-sperm antibodies (ASA), affect long-term sperm production or semen quality. Semen was collected from 8 mature dogs 3 times a week before and after hemicastratration and then 3 times a week after testicular biopsy (n = 3 and 1 control) or epididymal aspiration (n = 3 and 1 control). Detection of anti-sperm IgG (ASA) on sperm cells was performed by flow cytometry analysis using a flow cytometer. Two dogs with testicular biopsies became positive for ASA 16 d after testicular biopsy and remained positive for 7 and 9 d, respectively. One dog that had an epididymal aspirate became positive 13 d after epididymal aspiration and remained positive for 35 d. One dog became positive 21 d after hemicastration and remained positive for 28 d. Sperm output declined significantly in 7 of 8 dogs after hemicastration. A control epididymal aspirate treatment dog had decreased sperm output, and a testicular biopsy treatment dog had increased sperm output. None of the dogs with ASA had significant changes in sperm output after treatment. Sperm motility declined significantly in 3 dogs after hemicastration. An epididymal aspiration treatment dog had a decrease in sperm motility, a control epididymal aspirate treatment dog and a control testicular biopsy treatment dog each had increases in sperm motility. None of the dogs with ASA had significant changes in motility. The percentage of normal spermatozoa significantly decreased in 3 dogs and significantly increased in 1 dog after hemicastration. Two dogs that had testicular biopsies and 1 dog that had an epididymal aspiration had decreases in percent normal sperm. Two of 3 dogs with decreases in percent normal sperm after treatment had ASA, but 2 dogs with ASA had no change in motility. Hemicastration, epididymal aspiration, and testicular biopsy can induce ASA production within 2 wk of the procedure, but ASA are transient and do not have a predictably negative effect on total sperm output or motility. Testicular biopsy and epididymal aspiration are safe diagnostic procedures, but further work investigating post-treatment fertility must be done before final conclusions can be made.
