本研究通过甲基睾丸酮的口服处理完成了功能的性反转从而得到了全部雌性仔代的 XX 雄性个体。从游泳期开始、添加有1ppm、5ppm 和10ppm 浓度甲基睾丸酮的补充食物饲养58天,以后仍以正常的食物饲养,观察到在处理未期雌鱼无正常的卵巢。另雄鱼的百分率范围因激素的浓度而定在实验结束时为60—88。记录了激素处理期间的高死亡率。 In this study, sexual function reversal was accomplished by oral administration of methyltestosterone resulting in XX male individuals from all generations of females. Starting from the swimming period, supplemented with 1 ppm, 5 ppm and 10 ppm of methyltestosterone supplemented food for 58 days and thereafter remained normal food, observed in the treatment of unprocessed female normal ovaries. The percentage range for the other males depends on the hormone concentration at 60-88 at the end of the experiment. High mortality rates were recorded during hormone treatment.
