Summary.

The gonadal and epididymal sperm reserves of thirty-four camels from Egypt and thirty-six imported from the Sudan were studied haemocytometrically from tissue homogenates during the months of spring and autumn. The testes and epididymides of the first group were significantly larger than those of the second. Per gram of tissue, the testes of the camels from Egypt and the Sudan contained, respectively, 30·3±3·1 and 27·5±2·9×106 spermatozoa during autumn, and 47·2±3·9 and 36·4±3·3×106 spermatozoa during spring. The difference between the seasons was highly significant. The capacity of the epididymides to store spermatozoa increased significantly in the spring.

The body of the epididymides represented 49·6 and 46·1% of the total weight, and 68·8 and 68·6% of the total sperm reserves in the camels from Egypt and the Sudan, respectively.

The weight of the testes and epididymides showed a significant correlation with each other as well as with their sperm content in all groups. In camels from the Sudan, a further significant correlation was present between the sperm content in the testes and the epididymides.

Reproduction is committed to supporting researchers in demonstrating the impact of their articles published in the journal.

The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
