Methods to produce fixation between the tunica albuginea (visceral tunica vaginalis) and surrounding structures were used in Sprague-Dawley rats as an experimental model of orchiopexy to prevent testicular torsion. Eversion of the parietal tunica vaginalis without suture, or with absorbable or nonabsorbable suture produced excellent scarification, as did the use of talc. Absorbable and nonabsorbable suture, when placed between the parietal tunica vaginalis and tunica albuginea (visceral tunica vaginalis), produced only minor degrees of inflammation. Tetracycline instillation similarly failed to produce a significant inflammatory response.
