Abstract
A single oral dose of diβnβbutyl phthalate (DBP) to male rats caused a sloughing of the germ cells at 6 h, with more severe sloughing at 24 and 48 h. DBP is metabolized to monoβnβbutyl phthalate (MBP), which is transported through the bloodβtubular barrier into the seminiferous lumen. MBP is incorporated into the lumen at a maximum rate between 1 and 3 h after dosing with DBP. MBP caused decreases in the activities of succinate dehydrogenase in the Sertoli cells and sorbitol dehydrogenase in the germ cells, an increase in the activity of lactate dehydrogenase (LDH) in the germ cells and in the seminiferous lumen and a decrease in testicular iron levels.

This study reports changes in levels of ferritin, haemoglobin and transferrin in the bone marrow, liver and spleen as an attempt to determine the causes of testicular iron depletion. A single oral dose of di-n-butyl phthalate (DBP) to male rats caused a sloughing of the germ cells (at 6 h) prior to
Zinc deficiency affects the testicular tissues adversely. The testes of zinc-deficient rats showed variable degrees of degeneration compared to both control and zinc-supplemented ones. Initially, there was an early pronounced spermatic arrest followed by a series of degeneration of the cellular laye
