Estimate of cycle length (of seminiferous epithelium) based on reappearance of spermatids at 25-29 days and of sperm at 34-38 days

Range 8.7 Table - link days
Organism Mouse Mus musculus
Reference Oakberg EF. Duration of spermatogenesis in the mouse and timing of stages of the cycle of the seminiferous epithelium. Am J Anat. 1956 Nov99(3):507-16. p.512 table 2PubMed ID13402729
Method Periodic acid-Schiff technique
Comments "Application of the periodic acid-Schiff technique to mouse testis reveals 16 stages of spermiogenesis. The first 12 of these stages correspond to one cycle of the seminiferous epithelium, and have been used to establish the developmental sequences occurring during germ cell renewal in the mouse (Oakberg, ’56, in this number)....Data showing the progressive disappearance of cell generations are given in table 1 (BNID 110660). Curves were fitted for disappearance of each cell type, and time intervals between successive curves were read at the 50% point. ...When the data of table 2, which are based on repopulation, are treated in a similar manner, the estimate of cycle length is 8.702 days, with a standard error of .353."
