Abstract
Concentrations of GPC in the caput epididymidis are similar to those in the cauda epididymidis in rats (Riar et al., 1973; Brooks et al., 1974; Brown-Woodman et al., 1976) and rabbits (Holtz and Foote, 1978), others estimate slightly more in the cauda (Dawson and Rowlands, 1959; Dacheux et al., 1970; Setty et al., 1979). Epithelial cells from the caput contain more GPC than those from the corpus or cauda (Hoffmann and Killian, 1981) and the principal cells contain more than basal cells (Killian and Chapman, 1980; Hoffmann and Killian, 1981). Within the epididymal lumen there is more GPC in fluid than sperm cells (Brooks, et al., 1974). The concentration in epididymal fluid is high in the caput and is maintained distally (Table 15) whereas concentrations in spermatozoa increase as they mature (Quinn and White, 1967).
