A Comparative Study on Histochemical Distribution of Some Enzymes Related to Steroid and Glucuronide Synthesis in Seminal Vesicle and Testis of the Catfish, Clarias batrachus(Reproductive Biology)

In both seminal vesicle (SV) and testis of the catfish Clarias batrachus, a large number of interstitial cells are distributed, singly or in groups close to blood capillaries in the interstices of the secretory lobules and seminiferous tubules, respectively. They showed strong reactions for 3β-HSD, G-6-PD, NADH diaphorase and UDPGD activities. Both the germinal epithelium and SV epithelium showed moderate to strong reaction for UDPGD activity. These results strongly indicate that the SV is steroidogenic and capable of steroid glucuronidation, like the testis. It is suggested that the interstitial cells of the testis and SV are homologous having a common embryonic origin from the genital ridge.
