The two basic principles that are thought to be responsible for the ROP's purported effects are the low voltage DC galvanic current that is produced between the zinc and copper rods stimulating the Leydig cells of the testicles and the possibility of zinc ions being transfered into the testicles for increased testosterone production.
There should be no estrogen related issues with the ROP. Most estrogen problems that men develop are the result of excessive aromatase activity. Aromatase is an enzyme the turns testosterone into estrogen. Zinc is a powerful aromatase inhibitor.
Google "copper zinc battery", "electrochemical cell", "galvanic copper zinc cell" for the scientific principles of the two metals producing voltage current and ion exchange.
Tons of help! Thanks sasquatch.
Which leads to my next question... DLD, you selling these yet?
