Anatomical and histological study of the female reproductive system Steppe Agama, Trapelus agilis (Sauria: Agamidae)

This study evaluate the anatomical and histological structure of the female reproductive system in Trapelus agilis of the Agamidae family. Specimens of Trapelus agilis steppe lizard were collected in spring and summer from Shadegan area (Southwest of Khuzestan Province). Samples were anesthetized with chloroform after death (by intraperitoneal injection of Sodium pentobarbitone) and described in the laboratory. After that, their reproductive system was studied anatomically and then removed from the animal's body and tissue passage (dehydration, clarification, impregnation and molding) steps were performed on them. Following the cutting stage with a rotating microtome, serial sections were prepared from the female reproductive system. Following the cutting stage with a rotating microtome, serial sections were prepared from the female reproductive system. The results of this study showed that Trapelus agilis lizards wake up from hibernation in early spring and increase their physical strength to enter the reproductive phase by hunting insects. Histological results showed that lizard's ovaries began to increase in volume in spring and in the months (April and May) with a large number of follicles and in the months (June and July) are ready to ovulate.
