Pesticides represent a considerable source of environmental pollution. In this work the
effects of widely used pesticide namely, lannate and newly manufactured
organophosphorous pesticide namely tamaron on testicular ultrastructure of albino rats had
been studied. For each pesticide three groups were included control, low (received LD 50)
doses treated animals. In high dose treated animal received lannate there was extensive
cellular damage of the majority of seminiferous tubules and there was degeneration of the
Sertoli cells and all spermatogenetic cells including spermatogonia in addition there was
arrest of spermatogenesis. Rats received high dose of tamaron there was degeneration of
Sertoli cells and primary spermatocytes. In rats received low dose of lannate there was
degeneration of degeneration of Sertoli cells and primary spermatocytes.
However low dose treated tamaron morphologically abnormal sperm cells was
observed in some seminiferous tubules. In conclusion lannate and tamaron pesticides even
at low doses have toxic effect on testicular ultrastructure. |
