Sperm concentration in different segments of the goat epididymis

Spermatocrit values of fluid collected by micropuncture from the caput, corpus and cauda of goat epididymides as well as rete testis fluid and testicular fluid were determined for eight animals. The values indicated that 98.02% of fluid is absorbed in the epididymis and that the cauda epididymis contains the lowest amount of fluid, significantly different from the rete testis, corpus and caput.
