Abstract:
Captured wild chipmunks which have been extensively used for leprosy research, were studied in our laboratory for the reproductive potentials. Histologically normal organs, which are involved in reproduction in both sexes, were observed. Functionally active viable sperms in sufficient amount were produced by the males, and were used for artificial inseminations. A state of normal reproductive physiology of the females was also confirmed by studies on histologic analysis of oogenesis in the ovaries and in cultured ovaries in vitro. Regularity in ovulation was also determined by vaginal epithelial cell examinations. Thus these animals appeared to be normal in terms of fecundity. It was considered that the inability of these animals to have successful breeding in the captured state was due to problems in fertility, especially in maintaining the pregnancy.
