TDI is defined as the percentage of tubules reaching a particular stage of development (having at least three germ cells at a specific stage) (38).
**
Just one colony-like compartment was observed in a testis of 4 week group.
-Different letters represent significant difference between the amount of the treatment groups in a column (p<0.05).
