Summary

Testicular and epididymal sperm reserves were determined in six sexually mature Mujjafaranagri rams. The testes and epididymides weight were 151·4±5·49 and 20·7±0·164 g respectively. The total spermatids/g were 78±21·8×106, while daily sperm production per ram was estimated to be 4·46×109 when corrected for tunica albuginea weight. The number of spermatozoa in the caput, corpus and cauda epididymides were 3·18, 2·56 and 16·29×lO9 respectively and they represented 14·4, 11·6 and 73·9% respectively of the sperm reserves on that side. The total epididymal sperm reserve per male ram was about 44·06×109 spermatozoa.
