Treatment of female guppies from 1 day postpartum with L-thyroxine-sodium salt (Eltroxin, Glaxo) by immersion (0.5 ppm in 25% seawater renewed daily) significantly shortened the brood interval without affecting the brood size or the weight of the brood. This suggests an acceleration of early development of the fish by thyroxine. The thyroxine treatment also accelerated the development of the next batch of oocytes, particularly exogenous vitellogenesis (yolk-globule stages). The evidence suggests a role of the thyroid in vitellogenesis and gestation in the guppy.
产后1天的雌性孔雀鱼通过浸浴（在每天更新的25%海水中加入0.5 ppm左甲状腺素钠盐（优甲乐，葛兰素史克公司生产））进行处理，显著缩短了繁殖间隔，且不影响繁殖规模或幼鱼体重。这表明甲状腺素可加速鱼类的早期发育。甲状腺素处理还加速了下一批卵母细胞的发育，尤其是外源性卵黄生成（卵黄球阶段）。有证据表明甲状腺在孔雀鱼的卵黄生成和妊娠过程中发挥作用。
