Spermatogenesis in the thick-tailed bush baby,
Otolemur garnetti, was studied using light microscopy.
The stages and stage frequencies of the cycle of the
seminiferous epithelium were determined using semithin
sections stained with methylene blue-azure II. These
sections were obtained from the testes of six healthy
adult males (n=6). They revealed 11 stages of the seminiferous
epithelial cycle in this species. The mean relative
frequencies of the stages I–XI were 10.9, 6.0, 5.9,
7.3, 13.2, 10.7, 11.7, 9.2, 7.6, 8.9 and 8.6, respectively.
Comparisons were made between the frequency data in
the thick-tailed bush baby and equivalent data in the rat,
hamster, macaque, baboon, chimpanzee and man. There
was a significant correlation (P<0.05) between the
Otolemur data and equivalent stage frequency data of
two rodent species (rat and hamster) and monkey
(Macaca arctoides). However, there was no significant
correlation between the present data and those of the
baboon, chimpanzee and man. Possible phylogenetic
implications of these findings are discussed.
