title: Transport of carnitine by the epididymis of the cynomolgus macaque (Macaca fascicularis).
abstract: Unravelled tubules from the monkey caput and cauda epididymidis were perfused through the lumen in vitro during immersion in an organ bath kept at scrotal temperature and containing [3H]carnitine and [14C]inulin. The specific transport of carnitine from the bath to the lumen was constant for 4 h and reached a steady-state value of about 90 pmol/30 min per cm perfused length in the cauda and about 30 pmol/30 min/cm in the caput. These regional variations in carnitine transport differ from those found in the rat epididymis but may be relevant to human epididymal physiology.
