The histopathological impact of the sublethal concentrations of zinc, copper and lead on the gonads of Puntius conchonius was evaluated. Copper (Cu) interfered with spermatogenesis temporarily while zinc (Zn) and lead (Pb) produced dilation in the testicular blood capillaries with necrosis and disintegration of the seminiferous tubules. All three metals induced significant atresia in the ovary. The damaged mainly the younger oocytes, whereas Cu and Pb were more effective on relatively older oocytes. The studies suggest a direct action of heavy metals on the gonads.
评估了亚致死浓度的锌、铜和铅对孔雀鱼性腺的组织病理学影响。铜（Cu）暂时干扰精子发生，而锌（Zn）和铅（Pb）导致睾丸毛细血管扩张，伴有生精小管坏死和崩解。所有三种金属均诱导卵巢出现显著闭锁。损伤主要发生在较年轻的卵母细胞，而铜和铅对相对较成熟的卵母细胞影响更大。研究表明重金属对性腺有直接作用。
