The absorption of L‐carnitine from the duct of the proximal regions of the rat epididymis was investigated using a stopped‐flow, split‐droplet microperfusion technique. L‐carnitine was absorbed from the duct of the proximal caput epididymidis by a time‐dependent and saturable transport system (Km= 25 μm; Vmax= 0.65 pmoles absorbed/min/mm3tubular volume). Furthermore, absorption appeared to be primarily sodium‐independent, although the existence of a minor sodium‐dependent pathway cannot be ruled out. A similar transport system was not evident along the distal caput epididymidis, where absorption of L‐carnitine was attributable to passive diffusion only. The inward and outward movement of L‐carnitine across the epithelium of the proximal and distal caput epididymidis appears to be regulated so that the spermatozoa come into contact with high levels of L‐carnitine in the distal caput region.
