An integrated hypothesis explaining the implications of environmental influence on the reproductive process has not emerged owing to paucity of data. Nevertheless, evidence is at hand to show that favorable physiological disposition for reproduction is brought about with external and internal factors through the mediation of the neuroendocrine mechanisms. It is now clear that the environmental factors impinge on the exteroreceptors and through them affect the central nervous system, the hypothalamus, the pituitary and finally the gonad. Another endogenous factor is the internal rhythm, which is known to regulate at least in part the seasonal reproductive activity. A review of literature reveals that comparatively much work has been done on the structure and seasonal changes of the testes of fishes. The aim of the present study is to observe seasonal changes in the testes of fish Puntius ticto and their relation to heavy metal toxicity.
