C. Spermatozoa (S) were released from germinal epithelium in June 132. D. The thickness of spermatogenetic epithelium increased but spermatozoa decreased in July 132. E: Spermatozoa occluded the lumen of the seminiferous tubules in August132. F: The ger- minal epithelium atrophied in February 200. Spermatocytogenesis started from late April to early May, and the spermatocyte layers increased progres- sively in germinal epithelium. The testicular weights began to increase in May. By the end of the month, the germinal epithelium contained dividing sper- matogonia, spermatocytes and a few spermatides (Fig. 2B). In June, spermatozoa were released from germi- nal epithelium (Fig. 2C) without accompanying apparent increase in epididymal weights. The active spermatogonia division progressed until July. The thickness of spermatogenetic epithelium increased and the diameter of seminiferous tubules reached.
