Study of Spermatogenesis and Testes Histology of Laudakia caucasia (Stellio caucasicus: Agamidae) Species in Deh Gheibi Zone of Mashhad

Lizards are one of the most diverse and successful vertebrates in hot deserts of the world that biologists focus on their reproduction and gametogenesis. This research is experimental study and the aim of that is to investigation of spermatogenesis steps and sperm production limit identification belongs spring three months. 10 male lizards (Laudakia Caucasia, Syn: Stellio caucasicus: Agamidae) were collected at the end of each month. After determination and morphological studies, their testes were dissected of animal body and prepared for histological studies using light microscopy. Quantitative data were analyzed using SPSS by ANOVA and Kruskal-Wallis tests (P<0.05). Results showed that the spermatogenesis is started in the lizard from beginnings April and is gradually activated more with warming weather, As maximum spermatogenesis and mature spermatozoa production were observed in the end of June. Based on histological evidences, spermatogenesis step is activated from early spring and is continued to the late of spring. Maximum sperm production is in June.
