Reptiles generally reproduce sexually,[117] though some are capable of asexual reproduction. All reproductive activity occurs through the cloaca, the single exit/entrance at the base of the tail where waste is also eliminated. Most reptiles have copulatory organs, which are usually retracted or inverted and stored inside the body. In turtles and crocodilians, the male has a single median penis, while squamates, including snakes and lizards, possess a pair of hemipenes, only one of which is typically used in each session. Tuatara, however, lack copulatory organs, and so the male and female simply press their cloacas together as the male discharges sperm.[118] Most reptiles lay amniotic eggs covered with leathery or calcareous shells. An amnion (5), chorion (6), and allantois (8) are present during embryonic life. The eggshell (1) protects the crocodile embryo (11) and keeps it from drying out, but it is flexible to allow gas exchange. The chorion (6) aids in gas exchange between the inside and ...

Ascidians have been employed as model organisms in investigating spermatogenesis. 17b-hydroxysteroid dehydrogenase (HSD) is a steroidogenic enzyme essential for invertebrate spermatogenesis. A homologue of HSD was found in the EST database of Ciona intestinalis and cloned. Sequence analysis showed significant homology to zebra fish, sea urchin and human 17b-HSD. The gene has an open reading frame (ORF) of 918 nucleotides coding for a polypeptide of 306 amino acids and a calculated mass of 35-kDa. Immunoblotting with an antibody raised against HSD recognized a 35-kDa protein purified from the C. intestinalis testis. The HSD protein was localized in steroidogenic cells in the Ciona testis. These results suggest that C. intestinalis 17b-HSD is equivalent to the enzyme of vertebrate Leydig cells and that 17b-HSD could be a phylogenetic marker for organisms producing steroids.. Keywords 17b-HSD; Ciona intestinalis; Leydig Cell; ...
