梅花鹿在长茸期与发情期的睾丸组织结构

Change of Sika Deer Testicular Histomorphology During Antler Growth and Estrus Lin Huilian

在长茸期与发情期，梅花鹿的睾丸组织有明显的不同。长茸期（５，６月）的睾丸组织中的曲精小管萎缩，管中精原细胞排列稀疏，大部分精原细胞处于休静期，只有少量的初级精母细胞，未见次级精母细胞、精子细胞和精子。在发情期，曲精小管扩张，管中的精原细胞不断分裂增殖、分化发育、形成精子。在发情初期和后期。曲精小管中的生精细胞较少。但长茸期与发情期，曲精小管中的支持细胞总数没有显著的差异。
