Can taking prednisolone for a week's duration as a two or three year old child cause the child's penis to stop growing or shrink?

No: a two week course of properly prescribed Prednisone should not cause the penis to stop growing.

No: Prednisolone is a medication that mimics a natural stress hormone produced by the body's adrenal glands. It has nothing to do with the sex steroids made by the body. It has no influence on penile growth. Periodic use of this medication is well tolerated in a growing child with minimal side effects.The most common one I see is cranky, aggressive behavior, which ends with reduction of med.
