• Seasonal spermatogenetic changes were observed in the testis of a lizard, Eumeces latiscutatus, common in Japan-Hondo. During the months of April, May and early June, all spermatozoa are eliminated from the seminal tubules. Spermatogonial divisions occur in May and June. Primary and secondary spermatocytes and maturation divisions appear through July and August. Spermioteleosis is practically completed during from late November to December. During hibernation, there is no spermatogenetic activity in the testis.
