TESTICULAR PROSTHESIS IN A QUARTERHORSE STALLION - A CASE-REPORT

A testicular prosthesis was surgically removed from the scrotum of a Q uarterhorse stallion presented for evaluation of a large, firm, unilat eral scrotal mass. The prosthesis was constructed from methyl methacry late moulded around a roll of fiberglass casting tape. The prosthesis had been surgically implanted in the scrotum approximately 4 yr prior to presentation in order to give the appearance of 2 testicles in the scrotum for showing and breeding purposes. The horse had been used to successfully breed mares prior to presentation and produced 4.046 x 10 (9) progressively motile, morphologically normal spermatozoa in an eja culate collected 4 mo after surgery to remove the prosthesis. Ethical issues raised by this case are discussed.
