Abstract
RAM spermatozoa require 12 to 15 days to traverse the epididymis1 and during this time undergo changes which have been called maturation. In order to investigate these a technique has been developed for the continuous collection of spermatozoa before they enter the epididymis so that their in vitro metabolism may be compared with that of ejaculated spermatozoa from the same ram. The technique has also enabled a continuous collection of the fluid which is secreted by the testis and in which testicular spermatozoa are carried to the head of the epididymis. To our knowledge this investigation represents the first evaluation of testicular fluid and spermatozoa collected from conscious animals.
