Abstract

Morphological studies were made on the sp < /strong>erm reserve in the testis and vas deferns of 89 slaughtered growing Dokki-4cockerels. The pH of the incised testis was slightly acidic, while that of semen reserve in the vas deferens was slightly alkaline. The percentages of motility and normal spermatozoa increased significantly from 12 to 24 weeks of age as well as during their transportation through the excurrent ducts. The reverse of these findings was reported with the percentages of sperm with secondary abonormalities. The motility of testicular spermatozoa was discussed in the text, while the different forms of spermatids, normal and abonormal spermatozoa were illus trated.
