Procedure May Not Stop Child Molesters From Re-Offending

A serial child molester who made headlines when he asked to be castrated is now out of prison.

Larry McQuay was released from a Texas prison Wednesday after eight years behind bars.  McQuay had warned authorities he'd molest again and kill his victims if he wasn't castrated.

East Texas urologist, Dr. Brent Campbell, said the surgery decreases a man's sex drive because it takes away much of their testosterone.  But castration does not take away all of the desire for sex.

Castration is generally used to treat prostate cancer patients.

McQuay's request to be castrated prompted Texas to pass a law authorizing the procedure.
