  • Title: Effects of administration of testosterone on some biochemical correlates in seminal vesicle of Heteropneustes fossilis (Bloch) during preparatory phase: a study correlating changes in plasma testosterone level and testis activity.
    Author: Chowdhury I, Joy KP.
    Journal: Indian J Exp Biol; 2000 Jul; 38(7):713-9. PubMed ID: 11215316.
    Abstract:
    In the catfish H. fossilis, administration of testosterone (0.25, 0.5, 1 and 2 micrograms/g body weight for 20 days) during mid-preparatory phase (March) increased plasma testosterone, gonadosomatic index, seminal vesicle-somatic index and concentrations of total proteins, fructose and hexosamines in seminal vesicle (SV) and testis in a dose-related manner. In the lowest dosage (0.25 microgram) group, only the hexosamine and SV protein levels were significantly high. Glucose level decreased in a dose-related manner, the decrease being not significant in the 0.25 microgram group. The results indicate that testosterone stimulates SV and testicular secretions of total proteins, hexosamines and fructose in catfish. Decrease in glucose content suggests its conversion into fructose under testosterone stimulation.
