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.
在鲶鱼鲇属中，在准备期中期（3月）给予睾酮（0.25、0.5、1和2微克/克体重，持续20天），会使血浆睾酮、性腺体指数、精囊体指数以及精囊（SV）和睾丸中总蛋白、果糖和己糖胺的浓度呈剂量依赖性增加。在最低剂量（0.25微克）组中，只有己糖胺和精囊蛋白水平显著升高。葡萄糖水平呈剂量依赖性下降，在0.25微克组中下降不显著。结果表明，睾酮刺激鲶鱼精囊和睾丸分泌总蛋白、己糖胺和果糖。葡萄糖含量的下降表明其在睾酮刺激下转化为果糖。
