Abstract
The development of a technique for cannulating the rete testis permitted continuous collection of spermatozoa and fluid from the testis of conscious rams for up to 5 months (Voglmayr, Scott, Setchell & Waites, 1967; Voglmayr, 1970). When this technique was employed on bulls, the flow of rete testis fluid began to decline 4 to 5 days after surgery and ceased by Day 11 (Voglmayr, Larsen & White, 1970). Histological examination revealed that fibrous tissue had blocked the orifice of the catheter (J. K. Voglmayr, unpublished observations). Early cessation of flow was unusual in rams even if several attempts were required to insert the flexible catheter into the rete testis (J. K. Voglmayr, unpublished observations). This paper describes a modified
